Clean your KitchenAid ice maker by running the cleaning cycle, then flushing the water system

KitchenAid ice makers have a built-in cleaning mode that removes mineral buildup and bacteria from the internal water lines and ice-making components. You do not need to take the machine apart. The process takes about 30 minutes and uses a cleaning solution you can buy at any grocery store or online. Most models require you to run the cleaning cycle once every six months, or more often if you have hard water.

The exact steps depend on whether your model has a digital display or manual controls, but the principle is the same: fill the reservoir with cleaning solution, run the cycle, then flush the system with fresh water. This guide covers both types and walks you through what to expect at each stage.

Key Takeaways

  • KitchenAid ice makers have a dedicated cleaning cycle you access through the control panel or a manual valve, depending on your model.
  • You will need a commercial ice maker cleaning solution (citric acid-based products work well) and access to the water reservoir.
  • The cleaning cycle itself takes 15 to 20 minutes, but you should budget 30 minutes total to include the rinse cycle that follows.
  • After cleaning, run fresh water through the system for at least two full cycles before making ice again to remove all cleaning solution residue.
  • If your ice tastes or smells off, or if the machine produces less ice than usual, cleaning is often the first troubleshooting step.

What you need before you start

Gather these items before you begin: a bottle of commercial ice maker cleaning solution (brands like Affresh or Ice-O-Matic are common and cost $8 to $15), a clean cloth or sponge, and access to your ice maker's water reservoir. Check your user manual to confirm which cleaning solution your model accepts—most KitchenAid machines use citric acid-based cleaners, but some older models may have different requirements.

You will also need fresh water for the rinse cycle. If your ice maker is connected to your refrigerator's water line, make sure the water supply is turned on and the filter is not clogged. If your model has a manual water reservoir, fill it with fresh water before you start the rinse phase.

Turn off the ice maker before you begin. Most models have a power switch on the back or a button on the front control panel. Wait a few minutes for any remaining water to drain from the lines.

Running the cleaning cycle on a digital display model

If your KitchenAid has a digital screen or LED buttons, look for a "Clean" or "Cleaning" button on the control panel. Press and hold it for three to five seconds—your manual will specify the exact duration. The display should show a cleaning mode indicator, often a wrench icon or the word "Clean." Some models require you to press the button twice in quick succession; check your manual if nothing happens on the first try.

Once cleaning mode is active, open the water reservoir (usually located on the front or side of the machine) and pour in the entire bottle of cleaning solution. Do not dilute it. Close the reservoir and press "Start" or wait for the cycle to begin automatically—this varies by model. The machine will pump the solution through the ice-making mechanism and water lines. You will hear the pump running and may see solution dripping into the ice bin.

The cleaning cycle typically runs for 15 to 20 minutes. Do not interrupt it. When it finishes, the display will show a message like "Rinse" or "Cleaning Complete," and the machine will pause. Empty the ice bin of any solution-tinted ice and discard it.

Running the cleaning cycle on a manual control model

Older KitchenAid models without digital displays use a manual cleaning valve. Locate the small valve on the back or underside of the machine—it is usually labeled "Clean" or has a wrench symbol. Turn the valve counterclockwise (or pull it outward, depending on the design) to open the cleaning mode. Your manual will show the exact position.

Fill the water reservoir with the full bottle of cleaning solution. If your model does not have a reservoir, you may need to pour the solution directly into a funnel or opening at the top of the machine—again, your manual is essential here. Once the solution is in, turn the valve back to the closed position and wait. The solution will circulate through the system for 15 to 20 minutes. You may hear gurgling or see drips, which is normal.

When the cycle is complete, the flow will stop. Turn the valve to the cleaning position again and let any remaining solution drain into a bucket or sink. Then turn the valve back to the normal operating position. Empty the ice bin and discard any ice made during the cleaning cycle.

Flushing the system with fresh water

After the cleaning cycle ends, you must run fresh water through the machine to rinse out all cleaning solution. This step is critical—leftover solution will affect the taste of your ice and can damage the machine if left inside.

Fill the water reservoir with fresh, cold water. If your model is connected to a refrigerator water line, straightforward turn the water supply back on. Run the ice-making cycle twice without adding any cleaning solution. The first cycle will produce ice that may still taste slightly of the cleaning solution; discard this ice. The second cycle should produce clear, normal-tasting ice. If you are unsure whether the rinse is complete, run a third cycle.

Some KitchenAid models have a dedicated "Rinse" button or mode. If yours does, press it after the cleaning cycle ends and let it run to completion. Check your manual for the exact procedure on your model.

Common mistakes to avoid

Do not use vinegar or homemade cleaning solutions. KitchenAid machines are designed for commercial ice maker cleaners, and vinegar can leave residue or damage internal seals. Stick to the brands recommended in your manual.

Do not skip the rinse cycle. This is the most common mistake. Cleaning solution left in the lines will make ice taste bad and can corrode metal components over time. If you are in a hurry, at least run two full ice cycles with fresh water before using the machine normally.

Do not clean more often than necessary unless your ice tastes off or the machine is producing less ice. Over-cleaning can wear out seals and valves. Every six months is the standard interval for most households; hard water areas may need cleaning every three to four months.

Do not forget to empty the ice bin before you start. If you leave old ice in the bin, the cleaning solution may splash onto it, and you will have to throw it all away anyway.

When to clean your ice maker

Clean your KitchenAid ice maker every six months as routine maintenance. If you notice any of these signs, clean it sooner: ice that tastes or smells off, a decrease in the amount of ice produced, or visible cloudiness or discoloration in the ice. Hard water areas (high mineral content) may need cleaning every three to four months instead.

If your ice maker is connected to a refrigerator water line, also check the water filter. A clogged filter can reduce water flow and make the machine work harder, which can trigger the need for cleaning more often. Replace the filter according to your refrigerator manual, usually every six months.

Keep a note of when you last cleaned the machine. Write the date on a piece of tape and stick it to the back of the unit, or set a phone reminder for six months from the cleaning date. This straightforward habit prevents you from forgetting and helps you catch problems early.

Frequently Asked Questions

Can I use vinegar to clean my KitchenAid ice maker?

No. Vinegar can leave residue inside the machine and may damage rubber seals and gaskets. KitchenAid machines are designed for commercial citric acid-based cleaning solutions. Using vinegar may void your warranty and can affect ice quality.

What should I do if the cleaning cycle will not start?

First, check that the machine is powered on and the water supply is turned on. Make sure you are pressing the correct button or turning the valve the right direction—refer to your manual. If the machine still will not enter cleaning mode, the control panel or valve may need service. Contact KitchenAid customer support with your model number.

How long does the entire cleaning process take?

The cleaning cycle itself takes 15 to 20 minutes. Add another 10 to 15 minutes for the two rinse cycles with fresh water. Budget 30 to 40 minutes total from start to finish, including the time to empty the ice bin and refill the reservoir.

Is it safe to drink ice made right after cleaning?

No. Discard all ice made during the cleaning cycle and the first rinse cycle. The ice from the second rinse cycle should be safe, but if you are concerned about any residual taste, run a third cycle. It is better to waste a small amount of ice than to drink cleaning solution.

What if my ice maker is still making cloudy or bad-tasting ice after cleaning?

Make sure you ran at least two full rinse cycles with fresh water. If the problem persists, check your water filter—a clogged filter can cause poor ice quality even after cleaning. If the filter is new and the problem continues, the water supply line itself may be contaminated or the machine may need professional service.
