Clean your KitchenAid ice maker with vinegar and water every three to six months

A KitchenAid ice machine builds up mineral deposits and mold inside its water lines and ice-making surfaces, even if your water looks clean. Vinegar dissolves those deposits, and a straightforward rinse cycle removes them. The whole process takes about an hour and requires only white vinegar, water, and a soft brush — no special tools or chemicals.

Most KitchenAid models have a cleaning cycle built in. You run vinegar through the machine, let it sit, then run water through to rinse. The exact steps depend on whether your model is a countertop unit, an under-counter built-in, or part of a refrigerator. All follow the same principle: vinegar first, water rinse second, then make a batch of ice and throw it away before using the machine again.

Key Takeaways

  • Clean your ice machine every three to six months using white vinegar and water to prevent mineral buildup and mold growth.
  • Most KitchenAid models have a dedicated cleaning cycle — check your user manual for the exact button sequence or menu option for your model.
  • Always discard the first batch of ice after cleaning, since vinegar residue may linger in the lines.
  • If your machine has not been cleaned in over a year, run the vinegar cycle twice to break up heavy mineral deposits.
  • Call a service technician if the cleaning cycle does not run, if ice tastes like vinegar after rinsing, or if the machine stops making ice.

Gather vinegar, water, and a soft brush before you start

You will need white vinegar (the kind you use for cooking), tap water, and a soft-bristled brush or cloth. Do not use apple cider vinegar, balsamic vinegar, or any colored vinegar — they can stain or leave residue. A standard bottle of white vinegar from any grocery store works fine.

If your ice machine has a removable water filter, take it out now and set it aside. You will replace it after cleaning. If the filter is not removable, leave it in place — the vinegar will not damage it. Check your user manual to see whether your model has a water reservoir you can access, or whether water enters only through a built-in line connected to your home's water supply.

Run the cleaning cycle with vinegar

Locate the cleaning button or menu option on your KitchenAid machine. On countertop models, this is usually a button labeled "Clean" or "Cleaning Mode." On built-in models and refrigerator ice makers, it may be in a settings menu accessed through a digital display or a series of button presses. Your user manual will show the exact sequence — if you do not have the manual, search online for "KitchenAid [your model number] cleaning cycle" to find the instructions.

Fill the water reservoir (if your model has one) with white vinegar, or pour vinegar into the water inlet if the machine connects directly to your home's water line. Press the cleaning button and let the cycle run. The machine will pump vinegar through the ice-making mechanism and the water lines. This usually takes 15 to 20 minutes. Do not interrupt the cycle — let it finish completely.

Once the cycle ends, leave the vinegar sitting in the machine for 15 to 30 minutes. This gives the acid time to dissolve mineral deposits. You will see vinegar drip out of the ice chute or collection bin — this is normal. Place a small bowl or cup underneath to catch it.

Rinse thoroughly with water

After the vinegar has sat, run the cleaning cycle again, but this time use only water. Fill the reservoir or inlet with fresh tap water and press the cleaning button. Let the full cycle run. This flushes out the vinegar and any loosened mineral particles.

Repeat the water rinse a second time. Two water rinses are better than one, because vinegar smell or taste can linger if you skip this step. After the second rinse, the machine should smell like nothing — no vinegar odor at all.

Clean the ice chute and collection bin by hand

While the machine is rinsing, remove the ice collection bin and the chute cover (if your model has one). Rinse both under warm running water and wipe them with a soft cloth. If mineral deposits have built up on the plastic, dip your soft brush in white vinegar and scrub gently, then rinse with water.

Look inside the chute opening for any ice buildup or debris. Use a soft cloth or plastic scraper to wipe it clean — never use a metal tool, which can scratch the plastic or damage sensors. Dry the bin and chute with a clean cloth before putting them back in place.

Make and discard the first batch of ice

After cleaning and rinsing, run the ice-making cycle once and let it complete. Throw away the entire first batch of ice — do not use it. This batch may contain traces of vinegar or loosened mineral particles that rinsing did not catch. Making and discarding one batch ensures the lines are clear before you use the ice.

The second batch of ice is safe to use. If you notice any vinegar taste or smell in the second batch, run the water rinse cycle one more time and discard another batch.

Replace the water filter if your model has one

If you removed a water filter at the start, install a new one now. Do not reuse the old filter — it has trapped minerals and particles during the cleaning process. Most KitchenAid filters are replaced every six months anyway, so cleaning is a good time to swap it out.

If you do not know what filter your model uses, search for "KitchenAid [model number] water filter" online or check the manual. Filters are inexpensive and widely available. Installing a new one takes less than a minute and improves both the taste of your ice and the machine's performance.

Frequently Asked Questions

How often should I clean my KitchenAid ice machine?

Clean it every three to six months if you use it regularly. If you live in an area with hard water (mineral-heavy water), clean it every three months. If you rarely use the machine, every six months is fine. If the ice starts to taste odd or the machine slows down, clean it sooner.

Can I use a commercial ice machine cleaner instead of vinegar?

Yes, but vinegar is cheaper and works just as well for home machines. If you prefer a commercial cleaner, buy one made for ice machines and follow the instructions on the bottle. Never use bleach, ammonia, or bathroom cleaners — they can damage the machine and contaminate your ice.

What if the cleaning cycle does not start or the machine makes a strange noise during cleaning?

Check that you pressed the cleaning button correctly and that the machine is plugged in. If the cycle still will not start, the button or control board may be faulty — call a KitchenAid service technician. If the machine makes grinding or squealing sounds during cleaning, stop the cycle and unplug the machine, then contact a technician.

The ice still tastes like vinegar after I discarded the first batch. What do I do?

Run the water rinse cycle two more times and discard another batch of ice. Vinegar can linger in hard-to-reach lines if the machine has not been cleaned in a long time. If the taste persists after three total water rinses, the machine may have a clogged line — contact a service technician.

Do I need to turn off the water supply before cleaning?

No. The cleaning cycle controls the water flow automatically. If your machine connects to your home's water line, you do not need to shut off the main supply. If you are uncomfortable with water running through the machine, you can turn off the ice maker's water valve (usually located under the sink or behind the refrigerator), but it is not necessary.
