Turn off the ice maker and empty the bin before you start

The first step is to shut down the machine completely. Locate the power switch or unplug the unit from the wall outlet. Wait a few minutes for any remaining water to drain and for the interior to stop any active cycles.

Once the machine is off, remove the ice bin—usually a plastic or metal container that slides or lifts out from the front or bottom of the unit. Empty all ice into a sink or trash. Wipe the bin dry with a clean cloth before setting it aside. This prevents water from pooling while you work on the interior.

Key Takeaways

  • Always turn off and unplug your ice maker before cleaning any internal parts to avoid electrical hazard and accidental operation.
  • The water filter should be replaced every six months or according to your manufacturer's instructions, as a clogged filter reduces ice quality and production.
  • Vinegar and warm water dissolve mineral buildup inside the machine; run a cleaning cycle with this mixture, then flush with fresh water at least twice.
  • The ice bin, scoop, and any removable parts should be washed by hand with warm soapy water and dried completely before reassembly.
  • Mineral deposits and mold grow fastest in machines that sit unused for weeks, so clean every three to six months depending on your water hardness and use.

Replace or rinse the water filter

Most ice makers have a water filter that catches sediment and chlorine before water enters the freezing chamber. Check your user manual to find where the filter sits—usually behind a panel on the front or inside the machine near the water inlet.

If your filter is cartridge-style (a replaceable cylinder), unscrew or unclip it and install a new one rated for your machine's model number. If it is a mesh or screen filter, rinse it under running water while brushing gently with a soft toothbrush to remove trapped particles. A clogged filter slows water flow and forces the machine to work harder, which shortens its lifespan and produces smaller or cloudier ice.

Run a cleaning cycle with vinegar and water

Fill the water reservoir with a mixture of equal parts white vinegar and warm water. This solution dissolves mineral deposits (calcium and magnesium) that accumulate inside the freezing mechanism and water lines. Do not use bleach or harsh chemicals—they can damage plastic parts and leave toxic residue.

Plug the machine back in and run a full cleaning or test cycle if your model has one. If not, straightforward run the ice-making cycle once and let the vinegar solution flow through the system. You will see discolored water or ice come out; this is normal and shows the vinegar is working. Discard this batch of ice.

Flush the system with fresh water twice

After the vinegar cycle completes, empty the bin again and refill the reservoir with fresh, cold water only. Run another full cycle to rinse away vinegar residue. Discard this ice batch as well.

Repeat the fresh-water cycle a second time. This second flush removes any remaining vinegar smell or taste. Only after two fresh-water cycles should you use the ice for drinking or food. If you still detect vinegar odor, run one more cycle with fresh water.

Wash the bin and scoop by hand

While the machine is running its cleaning cycles, wash the ice bin and ice scoop (if your model includes one) in warm, soapy water. Use a soft sponge or cloth—abrasive scrubbers can scratch plastic bins and create places where mold can hide.

Pay special attention to corners and seams where mineral deposits or mold spores collect. Rinse thoroughly under running water and dry completely with a clean towel before putting the bin back in place. A wet bin left inside the machine can promote mold growth.

Reassemble and test the machine

Once the final fresh-water cycle is done and the bin is dry, slide or clip the bin back into its slot. Make sure it sits flush and locks into place—a loose bin can trigger error codes or prevent the machine from operating.

Run one more short cycle to confirm the machine is working normally. The ice should be clear and odorless. If you notice cloudiness, off-taste, or a vinegar smell, run another fresh-water cycle. Store the ice scoop in a clean, dry place between uses.

How often to clean and what to watch for

Clean your ice maker every three to six months, depending on your water hardness and how often you use the machine. Hard water (high mineral content) requires more frequent cleaning—every three months. Soft water and light use may only need cleaning twice a year.

Watch for these warning signs that cleaning is overdue: ice production slows down, ice cubes are smaller than usual, ice tastes stale or mineral-y, or you see white or gray buildup inside the bin or on the freezing mechanism. Machines that sit unused for more than a month should be cleaned before use, even if the calendar says it is not time yet. Stagnant water breeds mold and bacteria.

Frequently Asked Questions

Can I use bleach to clean my ice maker?

No. Bleach can damage plastic parts, corrode metal components, and leave toxic residue that contaminates ice. Stick to white vinegar and water, which are safe and effective for mineral and mold removal.

What if my ice maker has a self-cleaning cycle?

If your model has a built-in cleaning mode, use it instead of manually running vinegar through a regular cycle. Fill the reservoir with the vinegar-water mixture, press the cleaning button, and let the machine run its programmed cycle. Then flush with fresh water twice as described above.

Why does my ice taste like vinegar after cleaning?

You did not run enough fresh-water cycles to rinse out the vinegar solution. Run two or three more cycles with plain water only, discarding each batch of ice. The taste should disappear after the second flush.

Can I clean the ice maker while it is plugged in?

No. Always unplug the machine before opening panels, removing the filter, or touching internal parts. This prevents electrical shock and accidental operation while your hands are inside the unit.

What causes white buildup inside the ice maker?

White or gray deposits are mineral scale from hard water. These form on the freezing mechanism and inside water lines. Vinegar dissolves this buildup, but if you have very hard water, you may need to clean every two to three months instead of six.
