Start by turning off the ice maker and removing the bin

The fastest way to clean an ice maker is to shut it off first, then pull out the ice bin. Most ice makers have a straightforward on-off switch on the front or side of the unit — flip it to off. If your model has a lever arm that stops production when the bin is full, push that arm up to the off position as well.

Empty the bin completely into a sink or trash can. Throw away any ice that has been sitting for more than a few weeks, since it absorbs odors from the freezer and can taste stale. Once the bin is empty, set it aside — you will wash it separately in warm soapy water, then rinse and dry it before putting it back.

Key Takeaways

  • Turn off the ice maker and remove the bin before you start cleaning to avoid water leaks and electrical hazards.
  • Wipe down the ice maker's interior walls and the chute with a damp cloth or soft brush to remove mineral buildup and mold.
  • Clean the water inlet valve and supply line every six months if your water is hard, since mineral deposits block water flow.
  • Run water through the system for 30 seconds after reassembling to flush out any debris before making ice again.
  • Replace the water filter every six months to one year depending on your water quality and how much ice you make.

Wipe the interior walls and chute with a damp cloth

Once the bin is out, look inside the ice maker cavity. You will see the walls where ice forms and the chute (the channel where ice slides down into the bin). Mineral deposits from hard water and mold growth are the two things that build up here. Use a damp cloth or a soft-bristled brush to wipe down all interior surfaces. Do not use anything abrasive — steel wool or scouring pads will scratch the plastic or metal interior.

Pay special attention to the corners and the chute opening, where water pools and mold tends to grow. If you see stubborn white or gray mineral buildup, dampen the cloth with a 50-50 mix of white vinegar and water, then wipe again. Let the vinegar sit for a few minutes if the buildup is heavy. Rinse the entire interior with a fresh damp cloth afterward to remove any vinegar smell.

Clean or replace the water inlet valve and supply line

The water inlet valve is a small component that controls water flow into the ice maker. It sits behind the refrigerator, usually near the bottom, where the water line connects. If your water is hard (high in minerals), this valve can get clogged and stop the ice maker from working. You do not need to replace it often, but you should inspect it every six months.

To check it, turn off the water supply to the refrigerator (look for a small valve under the sink or behind the fridge). Disconnect the water line from the valve by turning the fitting counterclockwise. Look inside the valve opening — if you see white or brown mineral deposits, soak the valve in white vinegar for 30 minutes, then rinse it under running water. If the valve is cracked or the opening is completely blocked, it needs to be replaced. Reconnect the water line and turn the water back on.

Flush the system before making ice again

After you have cleaned the interior and reassembled everything, turn the ice maker back on and let water run through the system for 30 seconds. This flushes out any debris or vinegar residue left behind. You can do this by holding a cup under the water dispenser (if your fridge has one) or by letting the ice maker cycle once and throwing away that first batch of ice.

The first batch of ice made after cleaning may taste slightly off or look cloudy — this is normal and will clear up after one or two more cycles. If the ice maker does not produce ice after 24 hours, check that the water supply valve is fully open and that the inlet valve is not still clogged.

Replace the water filter on schedule

The water filter is your first line of defense against mineral buildup and mold in the ice maker. Most refrigerators have a filter cartridge that sits inside the fridge (usually in the upper corner or behind the crisper drawer) or behind the fridge itself. Check your manual to find yours. Replace it every six months if you have hard water, or every 12 months if your water is soft.

A clogged filter forces the ice maker to work harder and can cause it to freeze up or stop producing ice altogether. When you replace the filter, run water through the dispenser for 30 seconds to flush the new filter before using it. Mark the replacement date on your calendar or set a phone reminder so you do not forget.

Know when to call for professional service

If you have cleaned the interior, checked the inlet valve, and replaced the water filter but the ice maker still does not work, the problem is likely inside the machine itself — a frozen water line, a broken motor, or a faulty thermostat. These repairs require opening the ice maker housing, which usually means calling a refrigerator repair technician.

Before you call, make sure the ice maker is turned on, the water supply is on, and the freezer temperature is set to 0°F or below. Ice makers need a very cold environment to work, and if your freezer is warmer than that, no amount of cleaning will help. If those basics check out and the machine still will not produce ice, a technician can diagnose the internal problem.

Frequently Asked Questions

How often should I clean my ice maker?

Clean the interior and bin every three months if you use the ice maker regularly. If you have hard water or notice mold or mineral buildup, clean it monthly. Replace the water filter every six to 12 months depending on your water quality.

Can I use bleach to clean the ice maker?

No. Bleach leaves a toxic residue that can contaminate ice and drinking water. Use white vinegar and water instead, or a cloth dampened with plain water for routine cleaning. Vinegar is safe and removes both mineral deposits and mold.

Why is my ice maker making cloudy or slow ice?

Cloudy ice usually means minerals in your water are freezing along with it — this is harmless but a sign your water filter needs replacing. Slow ice production points to a clogged inlet valve or water line. Clean the valve and replace the filter, then wait 24 hours to see if production improves.

What if water is leaking from under my refrigerator?

Turn off the ice maker and water supply when ready. The leak is likely from a cracked water line or a loose connection at the inlet valve. Check all fittings behind the fridge to make sure they are tight. If a line is cracked, it needs to be replaced — do not try to patch it with tape.
