Clean the ice maker monthly to prevent mineral buildup and keep ice tasting fresh
A KitchenAid ice maker needs cleaning about once a month, depending on your water hardness. Mineral deposits from tap water collect inside the machine and can slow ice production, affect taste, and eventually clog the system. The cleaning process takes 15 to 30 minutes and requires only items you likely have at home: white vinegar, warm water, and a soft brush or cloth.
Most KitchenAid ice makers have two parts you can access without tools: the ice basket and the water filter. Some models also have a removable ice-making head or auger. Check your owner's manual to see which parts your specific model allows you to remove — not all KitchenAid models are identical, and forcing a part that should not come apart will damage it.
Key Takeaways
- Empty the ice basket and soak removable parts in equal parts white vinegar and warm water for 15 minutes to dissolve mineral buildup.
- Scrub the ice-making head and interior surfaces with a soft brush or cloth; do not use abrasive scrubbers that scratch stainless steel.
- Replace the water filter every six months or sooner if your water is hard, because a clogged filter reduces ice production more than mineral buildup does.
- Run a cleaning cycle with vinegar solution through the water line if your model has a built-in cleaning function, then flush with fresh water three times.
What you need before you start
Gather white vinegar, warm water, a soft cloth or non-abrasive sponge, and a soft-bristled brush — an old toothbrush works well. Do not use bleach, harsh chemicals, or abrasive scrubbers. Bleach can damage seals and leave a taste in ice; abrasive pads scratch the stainless steel interior and create places where bacteria can hide.
Turn off the ice maker and unplug it from the wall outlet before you begin. If your model is built into a refrigerator, locate the power switch on the ice maker itself — usually a small lever or button on the front or side — and turn it off. Wait five minutes for any remaining water to drain.
Remove and soak the ice basket and filter
Open the ice maker door and lift out the ice basket. Empty any ice into the sink. The ice basket is usually held in place by two clips or a straightforward slide mechanism; check your manual if you are unsure how to release it. Once removed, set the basket aside in your sink.
Locate the water filter, which is typically a cylindrical cartridge near the water inlet or inside the ice maker housing. Turn it counterclockwise by hand to unscrew it, or press the release button if your model uses a push-fit design. Do not force it; if it does not turn easily, consult your manual for the exact location and removal method.
Fill a bowl or sink basin with equal parts white vinegar and warm water. Submerge the ice basket and water filter in this solution for 15 minutes. The vinegar dissolves mineral deposits without damaging plastic or rubber seals. While these parts soak, move on to cleaning the interior.
Clean the interior and ice-making head
Dip a soft cloth into the vinegar-and-water solution and wipe down all interior surfaces you can reach: the walls, the bottom, and the ice-making head (the part that freezes water into ice). Pay special attention to any visible white, gray, or tan buildup — that is mineral scale. Wipe gently in circular motions.
Use a soft-bristled brush to scrub the ice-making head and any grooves or crevices where mineral deposits collect. The auger (the spiral part that pushes ice out) can usually be accessed by removing a cover or panel; check your manual. If you can remove it, soak it in the vinegar solution for 15 minutes, then scrub and rinse it thoroughly.
Do not pour vinegar directly into the machine or let it sit in the basin for more than 30 minutes, as prolonged exposure can damage rubber seals. Work quickly and rinse each part as soon as you finish scrubbing it.
Rinse everything thoroughly with fresh water
Remove the ice basket and water filter from the vinegar solution. Rinse both under running tap water for at least one minute each, turning them to reach all surfaces. Shake off excess water and set them on a clean cloth to air-dry for five minutes.
Wipe the interior of the ice maker with a cloth dampened in fresh water only — no vinegar. Repeat this step two more times to remove any vinegar smell or taste. Use a dry cloth for the final wipe to prevent water spots.
Once the ice basket and filter are dry, reinstall them. Slide the basket back into place and lock it according to your manual's instructions. Screw the water filter back in by turning it clockwise by hand until it is snug — do not over-tighten, as this can crack the cartridge.
Run a test cycle and check for leaks
Plug the ice maker back in and turn it on. Listen for the motor to start and watch for water to flow into the ice-making head. The first batch of ice may smell or taste slightly of vinegar; this is normal. Discard the first two batches of ice and run a third batch before using the ice for drinks.
Check the area around the water inlet and filter for drips. If water leaks from the filter connection, turn off the machine, unscrew the filter, and reinstall it, making sure it is seated properly. If the leak continues, the filter cartridge may be cracked and needs replacement.
When to replace the water filter instead of cleaning
The water filter cannot be cleaned and reused — it must be replaced every six months, or sooner if you have hard water or notice ice production dropping. A clogged filter restricts water flow more than mineral buildup does, and cleaning will not restore its function.
KitchenAid sells replacement filters specific to each model. Check your manual or the ice maker housing for the filter model number, then order the correct cartridge online or from an appliance parts retailer. Installation takes one minute: unscrew the old filter, screw in the new one, and run water through it for 30 seconds before making ice.
If you have very hard water (more than 200 parts per million of dissolved minerals), consider installing a whole-house water softener or using filtered water in your ice maker. This extends the time between cleanings and prolongs the life of the machine.
Frequently Asked Questions
Can I use vinegar in the water line to clean the ice maker automatically?
Some KitchenAid models have a cleaning cycle that runs vinegar through the water line. Check your manual for a "clean" or "descale" button. If your model has this feature, fill the water reservoir with equal parts vinegar and water, press the button, and let the cycle run. Afterward, fill the reservoir with fresh water and run two complete cycles to rinse.
How do I know if my ice maker needs cleaning?
Signs include slower ice production, smaller ice cubes, cloudy or discolored ice, or a stale taste. If you notice any of these, clean the machine even if it has been less than a month. Hard water speeds up mineral buildup, so you may need to clean more often than monthly.
What if I cannot remove the ice basket or filter?
Do not force any part. Consult your owner's manual for the exact removal steps for your model — some baskets slide out, others lift straight up, and some are held by clips. If the manual is lost, search for your model number online and read a replacement copy from KitchenAid's website.
Is it safe to use commercial ice maker cleaner instead of vinegar?
Commercial cleaners designed for ice makers are safe if used according to the product instructions. Vinegar is cheaper and works just as well for most mineral buildup. Avoid all-purpose cleaners, bleach, or descaling products meant for coffee makers, as these can damage ice maker seals.
Why does my ice taste like vinegar after cleaning?
You did not rinse thoroughly enough. Run three batches of ice and discard all of them before using ice for drinks. If the taste persists after the third batch, turn off the machine, remove the filter, and run fresh water through the water line for one minute to flush remaining vinegar from the pipes.
