Clean your ice maker by emptying the bin, wiping interior surfaces with a damp cloth, running a cleaning cycle with a commercial ice machine cleaner, and flushing the water lines

Most ice makers need cleaning every three to six months, depending on your water hardness and how often you use the machine. The process takes 30 minutes to an hour and requires only a cleaning solution made for ice machines, a soft cloth, and access to your machine's drain. You do not need to take the machine apart or call a technician for routine maintenance.

Cleaning prevents mineral buildup that slows ice production, removes bacteria and mold that grow in damp spaces, and keeps your ice tasting fresh. Hard water leaves calcium and lime deposits inside the water lines and on the evaporator plate where ice forms. If you skip cleaning, the machine works harder to make the same amount of ice and eventually stops producing altogether.

Key Takeaways

  • Turn off the machine and empty the ice bin completely before you start, because cleaning solution will contaminate any ice left inside.
  • Use only cleaners labeled for ice machines—household cleaners and vinegar can damage seals and leave residue that affects taste.
  • Most machines have a cleaning cycle you set up by holding a button or pressing a menu option; check your manual for the exact steps for your model.
  • After the cleaning cycle finishes, run the machine through two to three full dump cycles to flush out all cleaning solution before making ice for use.
  • Wipe the exterior and interior bin with a damp cloth weekly to prevent mold growth between deep cleanings.

Gather your supplies before you start

You will need a commercial ice machine cleaner—brands like Scotsman Ice Machine Cleaner, Manitowoc, or Ice-O-Matic make products designed for this purpose. Do not use vinegar, bleach, or all-purpose kitchen cleaners, because they can corrode metal parts, damage rubber seals, or leave flavors in the ice. Buy the cleaner at restaurant supply stores, online retailers, or sometimes at large hardware chains in the appliance section.

Gather a soft cloth or sponge (not abrasive scouring pads), a bucket or sink for rinsing, and your machine's manual or model number so you can look up the cleaning cycle instructions. Have a drain pan or towels ready in case water spills. Most cleaners cost between $15 and $30 per bottle and last through several cleanings.

Empty the ice bin and turn off the machine

Remove all ice from the bin and discard it. Scoop out any loose ice at the bottom. If the bin is difficult to access, check whether it slides out—many residential and small commercial machines have removable bins that make this step easier.

Turn off the machine using the power switch or by unplugging it. Wait five minutes for any residual water to drain and for the machine to cool slightly. This prevents the cleaning solution from evaporating too quickly and ensures it reaches all the surfaces that need it.

Wipe the interior and exterior surfaces

Use a damp cloth with plain water to wipe down the inside of the bin, the walls, and any visible surfaces where ice forms. Remove loose debris, dust, or any visible mold or slime. Pay attention to corners and crevices where moisture collects. This step removes material that the cleaning cycle alone cannot reach.

Wipe the exterior with a damp cloth as well. If your machine has a stainless steel finish, you can use a stainless steel cleaner after the ice machine cleaning is complete, but do not use it during the cleaning process itself.

Run the cleaning cycle with the commercial cleaner

Follow the instructions on your ice machine cleaner bottle for the amount to use—most require you to pour the concentrate into a water reservoir or directly into the machine's water line. Check your machine's manual for where to pour the cleaner; some machines have a dedicated cleaning port, while others require you to add it to the water inlet.

Turn the machine back on and locate the cleaning cycle button or menu option. On many machines, you hold down a button labeled "Clean" for three to five seconds, or you navigate a digital display to select "Cleaning Mode." The cycle typically runs for 15 to 20 minutes and pumps the cleaning solution through the water lines and over the evaporator plate where ice forms. You will hear the machine running and may see solution draining into the bin.

Do not interrupt the cycle once it starts. Let it run to completion. Some machines beep or display a message when the cycle finishes.

Flush the system with water cycles

After the cleaning cycle ends, turn off the machine and let it sit for five minutes. Then turn it back on and run a full ice-making cycle, allowing the machine to produce and dump a full batch of ice. This flushes cleaning solution from the water lines. Discard this ice—do not use it.

Repeat this dump cycle two more times. Run the machine, let it make a full batch, and dump the ice. After three complete cycles, the cleaning solution should be fully flushed out. If you notice any chemical smell or taste in the ice, run one more cycle.

Clean the bin and reassemble if needed

While the machine is running its flush cycles, wash the ice bin with warm soapy water and rinse it thoroughly. Dry it with a clean cloth. If the bin slides out, make sure it is completely dry before sliding it back in.

Once the final flush cycle is complete and the bin is clean and dry, your machine is ready to make ice for normal use. The ice produced after the third flush cycle is safe to use.

Maintain your machine between deep cleanings

Wipe the interior and exterior of the bin once a week with a damp cloth to prevent mold and mineral buildup. Empty any standing water from the bin if you notice it pooling. If your machine has a removable filter in the water line, check it monthly and replace it according to the manufacturer's schedule—usually every three to six months depending on your water quality.

If you have very hard water (more than 200 parts per million of minerals), clean your machine every two to three months instead of every six months. If you have soft water and use the machine lightly, you may be able to extend cleaning to every nine months. Watch for signs that cleaning is needed: slower ice production, smaller ice cubes, or a musty smell from the bin.

Frequently Asked Questions

Can I use vinegar to clean my ice maker?

No. Vinegar is acidic and can corrode the metal components and damage rubber seals inside the machine. It also leaves a vinegar taste in the ice. Always use a cleaner labeled specifically for ice machines.

What if my machine does not have a cleaning cycle button?

Check your manual for the model number and search the manufacturer's website for cleaning instructions—some older or commercial machines require you to manually run water through the system or have a different set up method. If you cannot find the manual, contact the manufacturer with your model number and they can walk you through it.

How do I know if my ice maker needs cleaning?

Signs include slower ice production, smaller cubes than usual, a musty or off smell from the bin, or visible mineral deposits on the evaporator plate. If you have not cleaned the machine in six months, it is time regardless of whether you notice symptoms.

Is it safe to use ice made during the cleaning cycle?

No. Always discard ice made during the cleaning cycle and the first two or three dump cycles afterward. The cleaning solution is not food-safe, and you need multiple cycles to flush it completely from the system.

What should I do if the machine leaks during cleaning?

Turn off the machine when ready and check that all water inlet connections are tight. Place a drain pan under the machine to catch any remaining solution. If the leak continues, the machine may have a cracked seal or internal damage—contact the manufacturer or a service technician before using it again.
