Most KitchenAid stand mixer problems trace to a few causes that KitchenAid’s own help pages name: oil separating from the grease, beater clearance that has drifted, a loose neck pin, overload and steam. The table below gives the first check for each.

KitchenAid describes a few drops of oil, a head that bounces under dough and a stop mid-batch as expected in some conditions. This guide does not come from using a mixer myself, and where KitchenAid’s pages disagree with each other, I say so.

Quick answers to common KitchenAid stand mixer problems

Oil leaking: what KitchenAid says is normal

KitchenAid’s product help page on oil leaks says the mixer is packed with enough solid grease to last its lifetime, and that the grease spreads over the gears as the mixer runs. Over time some oil can separate and settle at the lowest point of the motor head. That is just above the beater shaft if the mixer stands upright, or the speed control and lock lever slots if it was stored or shipped on its side.

The same page says this is more likely in warm weather and with a mixer that is not used often, and that regular use may prevent it. It also lists overusing the mixer without letting it cool completely between uses as a possible cause.

On how worried to be, KitchenAid says oil leakage will not harm the mixer, and that unless a fairly large amount has been lost it is most likely not a concern. If the mixer sounds normal and is not grinding, it can continue to be used. The grease is food grade and approved for incidental contact with food, but it can discolor light-colored frostings or mashed potatoes, and you do not need to add oil as maintenance.

What to do about it

• Wipe it first: clear oil from around the beater shaft and out of the bowl before mixing.
• After a long idle spell: the product help page says to run the mixer empty at speed 10 for about two minutes, switch it off, and wipe excess oil from around the planetary action. Fit the pouring shield first, because some oil can splatter.
• Going forward: KitchenAid’s troubleshooting guide says to store the mixer upright and run it at least once a month, with or without ingredients in the bowl.

When oil is a service job

KitchenAid says the only way to stop leaking completely is a service facility, where the old grease is removed, new grease packed in and the gasket replaced. The troubleshooting guide says to contact support if a large amount is lost, the leakage keeps returning after regular use, or the mixer starts grinding or sounding unusual.

Repair sites such as PartSelect publish a take-it-apart-and-regrease procedure. The KitchenAid pages I read do not give owners one. I did not read the warranty terms, so whether opening the housing affects coverage is something to ask KitchenAid before trying it.

Serious Eats reaches the same conclusion from the same pages: the grease is food grade, separation does not harm the mixer, and a fix needs a KitchenAid service facility.

Head wobble, bounce or won’t lock

Some movement is normal. KitchenAid’s help page for a bouncing tilt-head says the head bouncing a little when kneading bread or using heavy beaters is expected, and recommends kneading dough on speed 2. The head should not come unlocked during proper use.

If it keeps moving, KitchenAid’s pages give three checks in this order:

1. Is it dough, and on what speed? KitchenAid asks this first and recommends speed 2 for kneading, because heavy dough above that makes the head work harder.
2. Is the beater touching the bottom of the bowl? A beater set too low pushes into the bowl and makes the head bounce. The fix is the clearance adjustment below.
3. Is the silver neck pin loose? It runs through the neck of a tilt-head mixer and fastens the head to the base, with its rounded ends visible on both sides. The troubleshooting guide says it can be pushed back into place and its screw tightened, using a 1/8-inch hex drive or Allen wrench on some models. You reach the screw by laying the mixer on its side, and the guide sends you to your owner’s manual for where it is.

The two KitchenAid pages disagree on one detail. The product help page says that if the beater is too high, the head cannot lock. The troubleshooting guide says that if the head will not lock, the beater may be sitting too low and pressing into the bowl. Both lead to the same step, which is checking the clearance, so that is where to start.

A head that has fallen down is treated differently: the help page for it says to contact KitchenAid or use its service locator rather than adjusting anything.

Beater hits the bowl or misses the ingredients

KitchenAid says the flat beater is set at the factory to just clear the bottom of the bowl, and that the clearance can drift with shipping, time and use. The signs it lists are:

• Beater too low: it scrapes the bottom of the bowl, the white coating on a coated flat beater chips or wears, or the head bounces. KitchenAid’s product help says a chipped or worn white coating means the beater should be replaced.
• Beater too high: ingredients collect at the bottom of the bowl and are not mixed.
• Bowl-lift models, beater hitting the sides: the bowl is not snapped into place. It can look level without being locked, so you should hear a snap when you press down on the back of the bowl.

The dime test

KitchenAid’s adjustment guide says to put a dime in the bowl with the flat beater attached, turn the mixer on and watch the dime. If it does not move, the beater is too high. When the mixer is properly adjusted, the dime should move about a quarter inch inside the bowl with each pass of the beater.

The two KitchenAid pages describe the too-low result differently. The adjustment guide says the beater is too low if the dime does not move around the bowl smoothly, while the troubleshooting guide says it is too low if the dime moves continuously around the bowl. The quarter-inch figure is the same in both, so treat that as the target.

One caveat from the product help page: the dime test works for stainless steel bowls only, not glass or ceramic. Glass is made slightly differently, so KitchenAid says to adjust glass-bowl clearance without the dime until mixing performance is right.

Making the adjustment

1. Switch the mixer to off and unplug it.
2. On a tilt-head, tilt the head back and find the screw in the hinge. On a bowl-lift, lower the bowl-lift handle. The screw is in one of two places there, and the product help page shows both. That page also says mixers made before 1980 have no adjustment screw, so a service facility has to make the adjustment.
3. With the flat beater attached, turn the screw slightly: counterclockwise raises the beater and clockwise lowers it on a tilt-head, according to both the adjustment guide and the Ireland FAQ. The screw will not turn more than a quarter turn (90 degrees) either way, and the whole range is half a turn.
4. Repeat the dime test and adjust again if needed.

Three warnings come with it. If you over-adjust, the bowl lock lever on a tilt-head may not lock. KitchenAid’s product help says that on some bowl-lift models made after April 2003 the screw turns the opposite way, so if clockwise does not help, try the other direction.

The third is a wording clash on bowl-lift models. The product help page says counterclockwise raises the bowl, while the adjustment guide says counterclockwise raises the beater, and those have opposite effects on the gap. On a bowl-lift, make a very small turn, repeat the dime test, and turn back if the result is worse.

Stops mid-mix, won’t turn on, or runs hot

Stops during mixing

KitchenAid says some mixers have thermal overload protection that switches the motor off if it overheats or is overloaded, depending on what you were mixing and for how long. Once the mixer has cooled completely, about 30 minutes, it should start again. Steam is the other cause it names: steam from something hot can condense on the circuit board and cut the power, and the unit should restart in about three minutes once the steam clears.

The guide’s advice for dense mixtures such as sourdough, bagel dough or large batches is to use the dough hook and stay at speed 2.

Will not turn on

The product help page gives a faulty outlet and a tripped thermal overload protector as the usual reasons, and says to try another outlet first. The troubleshooting guide adds checking that the cord is fully in and that the speed control lever is at Off before you restart.

Warm head and a hot smell

KitchenAid says it is normal for the head to feel warm enough that you cannot comfortably touch it after long mixing, such as back-to-back batches of pasta or bread dough. Exceeding the ingredient capacity can also do it, and KitchenAid says speed 2 is the one to use for yeast doughs because a higher or lower speed can be hard on the motor. It says the exterior and motor can take 30 to 45 minutes to cool completely, and that continuing while the mixer is too warm to touch may cause damage.

KitchenAid also says its planetary action typically takes about half the time a recipe states to mix thoroughly. A faint warm smell during a long session is described as possible, and the guide says to switch off and rest the mixer. A smell during light work, one that returns after cooling, or one that comes with power loss or odd sounds is the point where it says to stop using the mixer and contact support.

Noises, bowl lock and speed control

• Clicking or tapping: light tapping can happen with dense mixtures like mashed potatoes or stiff dough. Check that the bowl is locked, the accessory is seated and the clearance is right. Repeated grinding, knocking or metal-on-metal sounds that continue after those checks are the signal to stop and call.
• Bowl will not lock, tilt-head: turn the bowl until it locks on the base plate. If it is still loose, KitchenAid says to inspect the bumps on the bowl base and base plate for wear, because worn ones mean replacing the bowl or plate.
• Bowl will not stay, bowl-lift: seat both sides on the support arms and press until you hear the snap. Kneading above speed 2 can unlock the bowl, and worn bowl clips may need replacing.
• Speed does not seem right: only the Stir speed (1) and the even numbers are labeled, with notches between them for the odd speeds. If the mixer runs only at high speed or only at low speed whatever you select, KitchenAid says to contact it.
• Beater hard to remove: the troubleshooting guide says not to store beaters, whips or dough hooks on the shaft, because it can make them harder to remove.

When KitchenAid says to stop and call

The troubleshooting guide lists these as the cases for support: power that keeps cutting out, oil leakage that keeps returning, a beater shaft that no longer rotates properly, adjustments that no longer hold, repeated grinding, a damaged power cord, or movement that gets worse over time. It also says that if something hard such as a measuring spoon fell into the bowl while mixing, an internal gear may be damaged.

It suggests having the model number, serial number and a description of when the problem happens ready, including whether it is under load, at every speed or only with one attachment.

How this guide was put together

The facts come from KitchenAid’s U.S. product help pages for stand mixers, its troubleshooting and adjustment guides, and the Ireland site’s oil leak FAQ, plus the Serious Eats article linked above. I have not used or opened a mixer myself.

Several things could not be established. KitchenAid’s owner’s manual PDFs would not download, so model-specific details such as the neck pin screw location are the help pages’ own pointer to the manual. KitchenAid’s page on a mixer tripping a GFCI explains what a GFCI is but gives no fix in the text I read. And this covers KitchenAid only; I did not read Cuisinart, Hamilton Beach or Bosch manuals for this guide.

Frequently Asked Questions

Is it normal for a KitchenAid stand mixer to leak oil?

KitchenAid says a few drops of oil near the beater shaft or in the bowl can appear over a mixer’s lifetime, because oil separates from the packed grease. It is more likely in warm weather and with infrequent use. KitchenAid says it will not harm the mixer.

Is the oil safe if it gets in food?

KitchenAid says the grease is food grade and approved for incidental contact with food prepared in the mixer. It can discolor light-colored foods such as frosting or mashed potatoes, so wipe away any residue before mixing. You do not need to add oil to the mixer as maintenance.

Why does my KitchenAid mixer head wobble?

KitchenAid’s pages give heavy dough above speed 2, a beater set too low that pushes into the bowl, and a loose silver neck pin. A little bounce while kneading is expected. Wobble with light mixtures, or that gets worse, is where it says to check the pin or call.

How do I adjust the beater height?

Unplug the mixer, tilt the head back and turn the hinge screw slightly counterclockwise to raise the beater or clockwise to lower it, no more than a quarter turn. Check with the dime test and repeat if needed. Some bowl-lift models made after April 2003 turn the other way.

Why does my KitchenAid mixer shut off while mixing?

KitchenAid names thermal overload protection and steam as the two causes. After an overload the mixer should restart once it has cooled for about 30 minutes, and after steam in about three minutes. Dough on speed 2 with the dough hook is the advice for dense mixtures.

How long should a KitchenAid mixer cool down?

KitchenAid says 30 to 45 minutes for the exterior and motor to cool completely when the head is too warm to touch comfortably. It says continuing while the mixer is too warm may cause damage, and that it can be turned back on once completely cooled.

The short version

Oil, a bit of bounce under dough and a stop after a long batch are all things KitchenAid describes as ordinary. Grinding, oil that keeps coming back, a head that gets worse, or a beater that stops turning are the ones it sends to service.

If you are choosing a mixer rather than fixing one, my best stand mixer for bread dough guide, my best stand mixer guide and the stand mixers hub cover the options, and the KitchenAid Classic vs Artisan comparison covers two tilt-head models for which the head and neck pin checks above apply.

Cleaning an espresso machine is two jobs: rinsing and wiping what coffee and milk touch, and descaling to remove mineral scale. The first is mostly the same on every machine. The second, and the detergent you use, depends on the machine, and the manuals for three popular machines give different answers.

This guide sets out what the Breville Bambino Plus, Gaggia Classic Pro and Nespresso Essenza Mini manuals say, and where the web’s usual advice, backflushing and vinegar included, goes beyond them.

What the three manuals say

The daily routine they agree on

• Milk machines: Breville says to wipe the steam wand after texturing milk and let it purge, because a wand that is not purged can block. Gaggia gives the same two steps: wipe, then open the steam knob for a second or two.
• Portafilter and baskets: Breville says to rinse them under hot water straight after use to remove coffee oils. Gaggia says to wash the filters daily in warm water.
• Shower screen: Breville says to wipe the group head and shower screen with a damp cloth, and to run hot water through with the basket in place and no coffee now and then. Gaggia says to brush grounds off the screen.
• Drip tray: Breville says to empty and clean it after each use or when the indicator rises; Nespresso says daily.

The steam wand not frothing guide covers what to check when a wand still performs badly after cleaning.

One machine’s cleaning cycle, step by step

The Bambino Plus is the only one of the three with a built-in cycle, so it is worth seeing what it asks for. This is the sequence in its manual:

1. Put the cleaning disc in the filter basket in the portafilter.
2. Place a cleaning tablet on top of the disc, then lock the portafilter into the group head.
3. Empty the drip tray and put it back, then place a 2 liter (68 oz) container under the portafilter and steam wand.
4. Fill the water tank to the MAX line and reattach it.
5. Hold the 1 CUP and 2 CUP buttons for 5 seconds, then press either one to start. The lights flash alternately while it runs.
6. When it finishes, rinse the portafilter, disc, drip tray and container.

The manual also says you can start the cycle yourself before the 200-extraction alert, by holding 2 CUP and STEAM for five seconds while the machine is off.

Backflushing: community practice, not a manual instruction

Backflushing means putting a solid basket or disc in the portafilter with detergent and running the pump, so that water is pushed back through the group head’s valve. Serious Eats recommends it with Urnex Cafiza tablets, as long as your machine can do it. My Home Barista says to do it weekly on machines with a 3-way solenoid valve, and names the Bambino and the Classic Pro.

None of the three manuals uses the word. The Bambino Plus manual builds a flushing cycle into the machine, with a cleaning disc and tablet, and starts prompting after 200 extractions. The Gaggia manual does not describe a backflush at all, and it warns not to clean the pressurized filter holder in the dishwasher or with washing-up liquid.

So for a Gaggia, backflushing is a widely repeated routine, not a Gaggia instruction. For a Breville, the cycle is the maker’s own version. Check whether your machine’s manual describes it before buying a blind basket.

Vinegar: the one place the sources split

Gaggia’s manual says never to use vinegar or other descaling agents. Nespresso’s descaling guide says vinegar or store-bought descalers may damage the machine. Serious Eats says no, citing strong odors and effects on the machine and the shots. My Home Barista allows it only as an emergency descale, because it is hard to rinse out and can affect seals.

Breville’s own blog guide goes the other way: it says that if you use vinegar, mix one part to one part water. Its Bambino Plus manual names a descaling agent and a cleaning tablet and does not mention vinegar. When the maker’s manual and a general guide disagree, I would follow the manual, especially while a machine is under warranty. Drip coffee makers are a different case: several drip makers give vinegar steps of their own, as the coffee maker descaling guide sets out maker by maker.

How often to descale, by maker

The intervals are tied to the machine and the water, not a single number. Gaggia says every 2 months, and elsewhere in the same manual 2 to 3 months. Nespresso’s guide says every 3 months or 300 capsules, whichever comes first, while its manual table runs from 300 to 1,200 cups by hardness. Breville’s machine tells you with its lights.

My own descaling guide covers the general reasoning for scheduling it.

What the manuals say not to do

• No dishwasher: Breville says not to clean any parts or accessories in it. Nespresso says never to put the appliance or any part in one. Gaggia says not to put the pressurized filter holder in one.
• No abrasives: Breville and Gaggia both say not to use abrasive pads or scouring cleaners on the machine; Nespresso adds no solvents, brushes or sharp objects.
• No immersion: all three say never to put the machine in water.
• Do not dry the brew group with a cloth: Gaggia says fibers can collect inside it.

If the machine leaks after cleaning, why an espresso machine leaks lists the usual causes.

If the machine will sit unused

• Breville: switch it off, unplug it, empty the water tank and drip tray, and make sure it is cool, clean and dry. Store it upright and put nothing on top.
• Gaggia: do not leave water in the tank for a long period, because it can become contaminated, and use fresh water every time. Do not keep the machine below 0°C (32°F), since water left in the heating system may freeze and cause damage.
• Nespresso: the Essenza Mini has an emptying mode for a long period of non-use and for frost protection. With the tank removed and the lever open, you hold both buttons for 5 seconds and it empties itself and switches off.

For Gaggia, a machine left idle for more than two weeks is treated like a new one, and the manual sends you back to its first-use instructions.

Grinders need their own routine: how to clean a coffee grinder.

How this guide was put together

The facts come from the Breville Bambino Plus instruction book, the Gaggia Classic Pro US manual, the Nespresso Essenza Mini manual and descaling guide, and the Serious Eats, My Home Barista and Breville blog pages linked above. It does not come from cleaning these machines myself.

Several things could not be established. I did not read a De’Longhi Dedica manual because De’Longhi’s manual page returned an error. I did not read a detergent label, so the Cafiza advice is the guides’ account of it.

Three manuals do not cover every machine, so if yours is not one of them, its own manual comes first. Reviews of two of these machines are at Breville Bambino Plus and Gaggia Classic Pro.

Frequently Asked Questions

How often should I clean my espresso machine?

Wipe the steam wand and rinse the portafilter and baskets after every use; both Breville and Gaggia say so. Drip trays are daily on the Nespresso. Deeper cleaning varies: Breville prompts after 200 extractions, while My Home Barista suggests weekly backflushing.

Do I need to backflush my espresso machine?

Only if your machine is designed for it. Serious Eats says to check first, and neither the Gaggia Classic Pro nor the Bambino Plus manual uses the word. The Bambino Plus has its own cleaning cycle with a disc and tablet, so follow your manual.

Can I clean or descale an espresso machine with vinegar?

Gaggia’s manual says never, and Nespresso’s guide says vinegar may damage the machine. Breville’s blog allows a one-to-one mix, but its Bambino Plus manual does not mention vinegar. Following the manual for your own machine is the safer reading.

Can espresso machine parts go in the dishwasher?

The manuals say no. Breville says not to clean any parts or accessories in the dishwasher, Nespresso says never to put the appliance or any part in one, and Gaggia says not to put the pressurized filter holder in one.

What is the difference between cleaning and descaling?

Cleaning removes coffee oils and milk residue from the parts coffee touches. Descaling removes mineral scale from inside the machine. Breville’s manual calls its cleaning cycle a flushing cycle that is separate from descaling, and each has its own prompt.

How do I clean a steam wand?

Wipe it with a damp cloth after every use and purge it. Breville says that if the holes are blocked you can unscrew the tip and use the cleaning tool stored under the water tank. Gaggia says you can unscrew the nozzle and wash it.

The short version

Wipe, purge and rinse every day, follow your own manual’s cleaning cycle and descaler, and treat vinegar as something the makers warn against. For fixes when something goes wrong, the coffee hub lists the espresso troubleshooting guides.

Rust on cast iron is surface rust, and every maker page read for this guide says it comes off. Scrub it away, dry the pan completely, wipe on a thin layer of oil, and re-season in the oven only if much of the seasoning went with the rust. Do not cook on a pan that still has rust on it.

The makers agree on the steps and disagree on the tools. Lodge reaches for steel wool first, and Field Company treats it as a last resort. The sections below set out both sides so you can match the method to your pan. If your pan is carbon steel, the carbon steel rust guide covers what its makers say.

Work out how bad the rust is first

What you see	What the maker pages say to do
A few orange spots or a dull orange film	Scrub, dry on heat, wipe with oil. Lodge says small amounts of rust may not need re-seasoning, and Field says to keep cooking if the rust was only in a few spots.
Rust across much of the surface, seasoning mostly gone	The same scrub, then an oven re-season. Lodge gives 450 to 500°F for one hour, and Field says one or two rounds.
Heavy rust all over, such as a vintage find	Field’s vinegar bath: equal parts white vinegar and water for about one hour, then scrub off what is left.
Black flakes and no orange	That is seasoning breaking down, not rust. Lodge calls the flakes carbonized oil and says they are not harmful.
Cracks, or deep pitting in the cooking surface	Real Simple says these are the only things likely to make a pan unrepairable.

Is it safe to cook on a rusty pan?

Remove the rust first. Field Company says not to use a skillet while it still has rust on it. An Ask Extension answer attributes two statements to the USDA: rust is not a food-safe material, and visible rust on a cast-iron skillet should be removed before you use it.

Stargazer takes a milder line, calling rust harmless iron oxide that only damages a pan if it is left for an extended time. The two views are not far apart in practice. Removal takes minutes, so there is little reason to cook on rust.

How to remove rust, step by step

These steps combine what Lodge, Field, Smithey and Victoria publish. The next section covers where they differ.

1. Scrub the rust off. Field uses a stiff brush or scouring pad, and Lodge uses steel wool or its Rust Eraser. Field suggests scrubbing under cold water, which it says helps stop the rust re-forming quickly. Lodge and Smithey both use warm soapy water. Keep going until no orange is left.
2. Rinse and dry at once. Towel dry, then put the pan on the stovetop. Field says to heat it over medium-low for about five minutes, because cast iron is porous and holds moisture you cannot see. Lodge says a few minutes on low heat.
3. Oil it thinly. Wipe a thin layer of cooking oil over the whole pan. Lodge says it should be thin enough not to drip or run when you tilt the pan, and recommends coating inside and out.
4. Check the surface. Field says that if you can still see or smell rust, you repeat the steps.
5. Decide on the oven. Few spots, keep cooking. Widespread rust, re-season, as set out below.

Where the makers disagree

Maker	Scrub tool	Vinegar	Oven re-season
Lodge	Rust Eraser or steel wool, warm soapy water	Not mentioned on the pages read	Only if the rust is extensive: 450 to 500°F, one hour, upside down
Field Company	Stiff brush or scouring pad under cold water; steel wool if you really need to	Equal parts with water, about one hour, severe rust only	One or two rounds if the rust is widespread
Smithey	Steel wool or chainmail scrubber with soapy water	Not mentioned	A small seasoning layer after drying; no oven temperature on the care page read
Stargazer	Hot water and an abrasive scouring pad	Not mentioned	Re-season at once; full oven seasoning is 475°F for one hour, in two or three layers on bare iron
Victoria	Steel wool	A vinegar-water spray if needed	425 to 500°F, upside down, one hour

The sharpest split is steel wool. Lodge’s cleaning page says it does not recommend steel wool or metal scrubbers for daily cleanup but that using them to remove rust is fine. Field says steel wool can sand down the pan, and a pan that is too smooth will not hold well-bonded seasoning.

These statements are about different things: Lodge is saying steel wool will not hurt a rusted pan, and Field is warning about taking off more iron than you need. A sensible reading is to start with the gentlest tool that moves the rust and keep steel wool for what is left.

When a vinegar soak makes sense

Field keeps the vinegar bath for heavy rust, and says nine times out of ten you will not need it. Its mix is equal parts white vinegar and water for about an hour, followed by scrubbing with an abrasive pad or steel wool. Martha Stewart’s rust guide uses the same mix for 30 minutes to an hour and says not to go longer.

That page then scrubs again, treats any remaining spots with a baking soda paste, rinses the pan thoroughly and dries it. It quotes two cleaning-company presidents, not a cookware maker, so weigh it accordingly. None of the maker pages read recommend an overnight soak.

Anything that takes the rust down to bare iron needs re-seasoning afterwards. Lodge says so directly for its Rust Eraser.

Re-seasoning in the oven

Lodge’s steps are the most complete. Apply a very thin layer of oil, set foil on the bottom rack to catch drips, put the pan upside down on the center rack, bake at 450 to 500°F for one hour, then let it cool in the oven. Victoria gives 425 to 500°F for one hour, and Stargazer gives 475°F for one hour after a short warm-up.

The common mistake is too much oil. Lodge says a sticky, gummy pan results from too much oil or too little heating, and says to put the pan back in the oven for another hour. The guide to cast iron that is sticky after seasoning covers that case, and seasoning that flakes off covers the other common failure.

Enameled cast iron with a rusty rim

Enameled pieces are different. Lodge’s enameled care page says rim rust can come from damp storage, drip-drying on a rack or the dishwasher. It recommends cleaning with a nylon sponge and dish detergent, drying thoroughly, and rubbing a small amount of cooking oil around the rim to seal it.

The bare vs enameled Dutch oven guide covers the difference in care. For stains and everyday washing on enamel, see how to clean enameled cast iron.

When a pan cannot be saved

Real Simple says cracks or heavy pitting on the cooking surface are the only things likely to make a cast iron pan unrepairable. It adds that a welder may be able to fix a crack, but that this is probably only worth doing for a piece with sentimental value. Before paying a welder, check whether the maker’s warranty covers it: see what to do if a cast iron skillet cracked. Ordinary surface rust, however widespread, is not in that category.

A rusty flat-top griddle follows the same logic, and why a Blackstone griddle rusts covers that case.

Keeping the rust away

• Do not soak it. Lodge says soaking is a recipe for rust, and Field says not to let the pan sit in water for more than a couple of minutes.
• Keep it out of the dishwasher. Lodge says a dishwasher will remove the seasoning and likely cause rust.
• Dry it on heat. Field, Smithey, Stargazer and Lodge all say to put the pan back on the stove after washing to drive off moisture.
• Oil it lightly. Smithey and Field both finish with a thin sheen of oil before storing the pan.
• Store it dry. Field says to keep the pan somewhere dry. My pan storage guide covers drying and storing cast iron alongside the rest of your cookware.

Soap is not the problem. Lodge says today’s dish soap is not strong enough to strip cast iron seasoning. For everyday care, see the cast iron skillet guide, and for the Dutch oven, how to clean a cast iron Dutch oven.

How this guide was put together

The facts come from the care and troubleshooting pages of Lodge, Field Company, Smithey, Stargazer and Victoria, Lodge’s enameled care page, and articles from Martha Stewart and Real Simple. It does not come from restoring a rusty pan.

Several things could not be established. The USDA wording comes from an Ask Extension answer, and the USDA’s own page was not found. No page read tests how much iron steel wool removes or how long a vinegar soak takes to etch a pan, so those points rest on the makers’ say-so. The maker pages carry no dates, so their steps may have changed.

Frequently Asked Questions

Can I cook on a cast iron pan with a little rust?

Remove it first. Field says not to use a skillet while it still has rust, and the Ask Extension answer quoting the USDA says to remove all visible rust. Stargazer calls rust harmless iron oxide, but scrubbing it off takes only minutes.

Do I need to re-season after removing rust?

It depends on how much there was. Lodge says small amounts of rust may not need re-seasoning, and Field says to keep cooking if only a few spots were affected. For widespread rust, both say to re-season in the oven.

Will vinegar ruin my cast iron pan?

The pages read give a time limit rather than a damage test. Field uses equal parts vinegar and water for about an hour, and Martha Stewart’s guide says 30 minutes to an hour and no longer. Neither mentions longer soaks.

Is steel wool safe to use on cast iron?

Lodge says steel wool is fine for removing rust, though not for daily cleaning. Field says it can sand down the pan so seasoning bonds poorly. Try a brush or scouring pad first and keep steel wool for stubborn patches.

Can I use dish soap on a rusty pan?

Yes. Lodge says soap is okay on cast iron, and both Lodge and Smithey scrub rust with warm soapy water. Lodge adds that the wash may remove some seasoning, which is fine when you are about to re-season the pan.

How do I stop cast iron rusting again?

Do not soak it or put it in the dishwasher. After washing, dry it on the stovetop over low to medium-low heat, wipe on a thin layer of oil, and store it dry. These steps appear on the Lodge, Field and Smithey pages.

The short version

Scrub, dry on heat, oil, and repeat if you still see rust. Go to the oven only when much of the seasoning has gone, and keep vinegar for the heavily rusted vintage pan. If you are shopping for a replacement, the best cast iron skillet guide has the picks, and the cookware hub lists the rest.

Most Keurig faults come down to four things: too little water or a badly seated reservoir, clogged needles, scale, or a power problem. Keurig’s own guides cover all four. Refill and re-seat the reservoir, run a water-only brew, clean the needles with a paper clip, and descale.

The steps below come from Keurig’s Use & Care guides for five models, so button names and lights differ by brewer.

Find your symptom first

What is happening	What Keurig’s guides list first
Nothing comes out when you press brew	Water below the brew minimum, reservoir not seated, handle not fully down

Check the water and the reservoir first

The K-Slim guide and the K-Supreme guide both say a minimum of 6 ounces of water is required to brew. Their fix for a brewer that will not brew is to add another 2 ounces to the reservoir, press brew, and repeat until it begins to dispense.

The K-Elite guide and the K-Duo Essentials guide say the same thing differently: if the add water light is on, fill to and not beyond the MAX line, and make sure the reservoir is seated properly in its base. If the light stays on after refilling, both guides tell you to contact Customer Service. They also say to push the handle down securely after placing the pod.

The K200 (Keurig 2.0) guide adds a step for a touch-screen brewer that says “More Water Please” even after refilling: remove the reservoir, empty it, clean it thoroughly, fill it to the MAX line, and seat it properly again. If the reservoir was taken off during brewing, the K-Duo, K-Elite and K200 guides all say to put it back and run a rinsing brew without a pod.

It brews only part of a cup

Keurig’s list for a partial cup is short, and the guides give it the same way:

• Purge the brewer (K-Slim and K-Supreme): power it off, hold the brew button and the 12 oz button for 5 seconds until water starts dispensing, release, let it purge, discard the water, and power it back on.
• Clean the exit needle, which may be clogged.
• Clean the K-Cup pod holder (K-Slim and K-Supreme).
• Descale. If you have run the descale procedure twice and it still brews a partial cup, the guides say to contact Customer Service.

The K-Duo’s carafe side has its own causes. Its guide lists a clogged drip stop, which means removing the filter basket drawer and rinsing the plunger, and not enough water for the size selected. It also warns that more than 15 tablespoons of ground coffee, or 12 for decaf, may overflow, and says to contact Customer Service about short carafe brews at high altitude.

How to clean the needles

Grounds in the cup and slow or partial brews often trace back to the two needles. The K-Slim and K-Elite guides give this method, and the K200 guide is close to it:

1. Exit needle. Remove the pod holder assembly and detach the funnel. The exit needle is on the inside bottom of the pod holder. Push a straightened paper clip into it to loosen any grounds.
2. Entrance needle. Lift the handle and find the needle on the underside of the lid. Hold the handle up, and with your other hand carefully push a straightened paper clip into the holes and move it around gently.
3. Rinse. Lower the handle completely and run two water-only brew cycles, with no pod.

The K200 guide marks both with a caution: the needles are sharp, so do not put your fingers in the chamber.

Descaling

Keurig says scale is non-toxic but can hinder performance if left alone. The K-Slim guide says to descale every 3 months, and the K-Elite guide says every 3 to 6 months, so it depends on the model and on how hard your water is.

The procedure is the same in outline in each guide: use no pod, pour a bottle of Keurig Descaling Solution into an emptied reservoir, run rinse brews into a large mug, rest the brewer, then rinse with fresh water.

The details differ. On the K-Slim you hold the 8 oz and 12 oz buttons together for 3 seconds to enter Descale Mode, and the guide allows 15 to 20 minutes. The K-Elite uses the hot water button, lets the brewer stand for at least 30 minutes, then asks for at least 12 fresh-water rinse brews, and allows about 45 minutes. Follow your model’s own guide for the button sequence.

A heavily scaled brewer may give only a small amount of water, or none, followed by the sound of air blowing out. Keurig’s guidance is to turn it off and unplug it, discard any descaling solution in the reservoir, rinse the reservoir and refill it with fresh water, then plug it in and repeat the fresh-water rinse. If it still does not run normally, leave it unplugged for at least 30 minutes before continuing the rinse.

For espresso machines the interval is a different question, which this site’s guide to how often to descale an espresso machine covers. For drip machines, and for pod brewers whose guide you no longer have, the site’s coffee maker descaling guide covers the general procedure.

No power, or it shuts off

• The power button. Check it has been pressed. On the K-Duo, the guide says to press the OZ or CUPS button, and on the K200 to press and hold the power button until the touch screen lights.
• A shared circuit. Every guide read says to plug the brewer into its own grounded outlet, because an overloaded circuit may stop it working properly.
• Automatic shut-off. The K-Slim and K-Supreme guides say the brewer turns itself off 5 minutes after the last brew, and the K-Duo guide says 60 seconds. Pressing the power button restarts it.

If it still has no power after those checks, the guides say to contact Customer Service.

Lights and screen messages

The K200 guide lists four touch-screen alerts. “More Water Please” is covered above. “Sorry, Brew Interrupted” means slowly lifting the handle, removing the pod, lowering the handle and running a rinsing brew. “Sorry, There is a Problem” points to grounds stuck in the entrance needle.

The water filter reminder appears after every 1,000 ounces or two months, and you press YES to reset it after replacing the filter.

The button-light models are blunter. The K-Elite guide says that if the 4, 6, 8, 10 and 12 oz lights all blink together, you should contact Customer Service, and the K-Duo guide says the same for all buttons blinking at once. If those lights and the ICED light are all on at once on the K-Elite, lift the handle, remove any pod, close it over a large mug and press the power button once.

Water, storage and cold

The K-Supreme guide recommends bottled or filtered water if you notice a chlorine or mineral taste, and says not to use distilled water. For storage it says to empty the reservoir, and to let a brewer that has been below freezing warm to room temperature for at least 2 hours before using it. After storage it recommends rinsing the reservoir and descaling.

Fixes you will see online that the guides do not mention

Some pages suggest turning the brewer upside down and shaking it, or resetting a thermal fuse. None of the five Keurig guides read for this page mention either, so they are not covered here. If one of Keurig’s own steps does not work, the next step in every guide is Customer Service rather than a repair.

When to stop and call Keurig

Call when the guide for your model says to: the add water light stays on after a refill, all the lights blink, it brews a partial cup after two descales, or it has no power after the outlet and button checks. The guides give 1-866-901-BREW (2739).

The guides describe a one-year limited warranty, and they say not to return a brewer without first getting a Return Materials Authorization number from Customer Service. They also say damage caused by non-Keurig pods or accessories may not be covered.

How this guide was put together

The facts come from Keurig’s Use & Care guides for the K-Slim, K-Supreme, K-Duo Essentials, K-Elite and K200. It does not come from repairing or testing a Keurig.

Several things could not be established. Keurig’s support site articles would not load for this guide, so only the printed guides were read. Other models, including the K-Mini and K-Cafe, were not read, and their steps may differ. Nothing here says how often each fault occurs, because the guides do not give failure rates.

Frequently Asked Questions

Why will my Keurig not brew?

Check the water first. Keurig’s K-Slim and K-Supreme guides say at least 6 ounces is needed to brew, and its other guides say to fill to the MAX line and seat the reservoir properly. Then check the handle is down, clean the needles, and descale.

Why does my Keurig only brew half a cup?

Keurig’s guides list a clogged exit needle, scale, and a reservoir removed mid-brew. Clean the needle with a straightened paper clip and run a rinsing brew. If two descales do not fix it, the guides say to contact Customer Service.

How often should I descale a Keurig?

Keurig’s K-Slim guide says every 3 months, and its K-Elite guide says every 3 to 6 months. Hard water builds scale faster, which is why the guides give a range. Use Keurig Descaling Solution and follow the steps in your own model’s guide.

Why does my Keurig say add water when it is full?

The reservoir is probably not seated properly in its base. Keurig’s guides say to remove it, seat it again, and fill only to the MAX line. If the message persists on a touch-screen model, empty and clean the reservoir, then refill it.

Can I use distilled water in a Keurig?

Keurig’s K-Supreme guide says not to use distilled water, and recommends bottled or filtered water if you notice chlorine or mineral tastes. Its other guides read here do not address the question, so check the guide for your own model before choosing.

Why does my Keurig keep turning off?

It may be the automatic shut-off, which Keurig’s guides put at 5 minutes on the K-Slim and K-Supreme and 60 seconds on the K-Duo. A shared outlet can also cause it, because the guides say the brewer should be on its own grounded outlet.

The short version

Water and the reservoir seat first, then needles, then scale, then power. Keurig’s guides stop at Customer Service after that, so do not open the brewer. If you are choosing between pod and drip machines, read single-serve vs drip coffee makers, and for a different machine that leaks, coffee maker leaking covers the causes. The coffee hub lists the rest.

Yes, you can use cast iron on an induction cooktop. Cast iron is magnetic, so bare and enameled cast iron both work without an adapter. What changes is how you handle it: heat it slowly, match it to the zone, and lift it instead of sliding it across the glass.

The sections below cover each of those points, and the one place where the makers disagree.

Why cast iron works on induction

Whirlpool’s help page says most induction-compatible cookware is made from ferrous materials, which contain iron, and lists cast iron and enameled steel as examples. Lodge’s own induction page explains it the same way: induction heats cookware with magnetic fields, so the pan must contain a ferrous metal, which makes cast iron a good fit. ABC News gives it as a main benefit of cast iron that it can be used on any cooktop surface, induction included.

That puts cast iron in a different group from aluminum and copper, which Whirlpool says typically do not work unless they have a magnetic base. This site’s guides cover those cases in copper pans on an induction cooktop and using a moka pot on an induction stove.

Three things that change on induction

Preheat slowly

Lodge says the magnetic fields on induction cooktops are very efficient, and that heating a skillet too quickly can leave the temperature of the iron unbalanced, causing thermal shock. In severe cases, it says, that can break cookware on the stovetop. Its advice is to preheat slowly with oil: the skillet is ready when the oil shimmers and ripples, and if the oil starts to smoke the pan is too hot and should come off the heat for a minute or two.

Match the pan to the zone

Lodge tells you to choose the piece closest to the size of the burner, and says many induction cooktops detect cookware size, so a skillet that is too small for the burner may not switch the zone on. Whirlpool and Jenn-Air say the same thing, and Jenn-Air adds that oversized pans may decrease performance. None of them gives a single number, because each cooktop sets its own minimum, so your manual is the final word.

Full contact is not required

Lodge says cookware does not have to sit flush with the burner to heat. Some pieces sit flush or nearly flush, and others have a heat ring that leaves a small gap, and a few millimeters of distance does not change how well the pan heats.

Will cast iron scratch the glass?

This is the one point where the sources do not line up, so here is what each says.

Source	What it says
Lodge (cast iron maker)	Its cookware is cast very smooth on the bottom and should not scratch, but lift it between burners rather than sliding it
GE (appliance maker)	Do not use cookware with a rough bottom such as cast iron, do not slide cookware, and coarse particles like salt or pepper trapped under a pan can scratch
Bosch (appliance maker)	Avoid cookware with rough bases such as cast iron pans, because scratches cannot be removed once they happen
Jenn-Air (appliance maker)	Do not slide cookware, keep pan bottoms clean and dry, and check flatness with a ruler: no space or light should show under it

The two sides are not really contradicting each other. Lodge is describing its own smooth-cast bottoms, and GE and Bosch are warning about rough ones. What none of these pages tells you is how smooth your particular pan is, which matters most for an older or rough-cast skillet.

So the check is yours to make:

• Run your hand over the base. If it feels gritty or has burrs, it is the rough kind that GE and Bosch warn about.
• Lay a ruler across the bottom, as Jenn-Air describes. Light under the edge means the pan is not flat.
• Wipe the base and the cooktop before every cook, since GE names trapped salt and pepper as a cause of scratches.
• Lift the pan on and off, and never drag it between zones.

GE also says small scratches typically become less visible after cleaning, and that some marks that only look like scratches come off completely. Bosch says real scratches cannot be removed.

How heavy it is matters on glass

ABC News lists weight as a main drawback of cast iron, especially when the pan is filled with food. On this site’s Lodge 12-inch skillet review the listing gives about 7.9 pounds empty. A pan that heavy is awkward to lift cleanly, so use both hands and never slide it to reposition it.

Bare or enameled cast iron

Both work. Whirlpool lists cast iron and enameled steel among its examples, and this site’s best cast iron Dutch oven guide says all cast iron Dutch ovens, enameled or bare, work on induction. ABC News adds that the enamel on enameled cast iron can chip and scratch, so look at the base as well as the cooking surface. Bare vs enameled cast iron covers the choice itself.

Griddles and double-burner pans

A pan that spans two zones is the case where cast iron can go wrong. Lodge says that with a larger griddle, such as a reversible grill/griddle, a bridge burner that sends heat to the gap between the main burners helps it heat evenly and reduces the risk of thermal shock. If the distance between the edge of the piece and the cooking surface is too large for it to heat efficiently, Lodge says to switch to a piece closer to the size of the burner.

Whether your cooktop has a bridge burner is a feature of the cooktop, so check its manual before buying a double-burner griddle for induction. I compare five options in my best griddle for induction cooktops guide.

How to check a pan you are not sure about

Not every pan that looks like cast iron is cast iron, and an old skillet may carry no marking at all. Whirlpool’s test is simple: hold a magnet against the bottom, and if it sticks firmly the pan is induction compatible, while a magnet that slides off or does not stick at all means it is not suitable. The word “cast” on a label is not the test, because Whirlpool says aluminum typically does not work on induction unless it has a magnetic base.

If you are buying, this site’s best cast iron skillet guide states that every pan on its list works on induction, and its reviews give each pan’s weight so you can judge how easy it is to lift.

What usually goes wrong

• Heating on high straight away. Lodge’s thermal shock warning is the main risk specific to induction.
• A small skillet on a large zone. The cooktop may not detect it, so it will not switch on.
• Sliding the pan across the glass. Lodge, GE and Jenn-Air all say to lift.
• Grit under the base. GE says trapped coarse particles scratch, so wipe both surfaces.
• An old, rough-bottomed pan. This is the case GE and Bosch single out.
• A large griddle without a bridge burner. Lodge says it may heat unevenly.

How this guide was put together

The facts come from Lodge’s induction page, Whirlpool’s and Jenn-Air’s help pages, GE’s and Bosch’s pages on scratches, ABC News, and this site’s own Lodge review. It does not come from cooking on an induction cooktop.

Several things could not be established. None of the pages used here addresses cast iron making noise on induction, or how evenly a large skillet heats across a small zone. No independent test of scratching was found, only each maker’s advice. Le Creuset’s and Staub’s own induction guidance was not read for this guide.

Frequently Asked Questions

Can you use cast iron on an induction cooktop?

Yes. Cast iron is magnetic, and Lodge, Whirlpool and ABC News all say it works on induction. Preheat slowly, match the pan to the zone, and lift it instead of sliding it. No adapter is needed, unlike aluminum or copper pans without a magnetic base.

Does enameled cast iron work on induction?

Yes. Whirlpool lists enameled steel among its induction-compatible examples, and this site’s Dutch oven guide says enameled and bare cast iron both work. Check the base for chips, because ABC News says enamel can chip and scratch, and handle it the same way as bare iron.

Will cast iron scratch an induction cooktop?

It can. Lodge says its smooth-cast bottoms should not scratch, but GE and Bosch warn against rough-bottomed cast iron, and trapped grit can scratch too. Check the base, wipe both surfaces, and lift the pan rather than sliding it. Bosch says scratches cannot be removed.

Does cast iron have to touch the whole burner?

No. Lodge says cookware does not have to make full contact to heat, and that a few millimeters of gap, such as from a heat ring, does not change how well the pan heats. Size matters more: choose a pan close to the size of the zone.

Can you use a cast iron griddle on induction?

Yes, with care. Lodge says a larger griddle heats more evenly on a bridge burner, and that a piece too far from the cooking surface may not heat efficiently. Choose one close to your zone’s size, and check your manual for a bridge feature.

What heat setting should cast iron use on induction?

Start low and go up slowly. Lodge gives no dial setting, because cooktops differ, only the signal: the oil shimmers and ripples when the skillet is ready. If the oil smokes, take the pan off the heat for a minute or two before cooking.

The short version

Cast iron works on induction, bare or enameled, with no adapter. Preheat slowly, match the zone, check the base for roughness and grit, and always lift.
