Clean the water reservoir and filter first

The water reservoir is where bacteria and mineral buildup start, so empty and rinse it every week. Most countertop models have a removable reservoir at the back or side — check your manual for the exact location. Empty any remaining water, then wash the inside with warm water and a soft cloth or sponge. Do not use abrasive scrubbers, which can scratch the plastic.

If your model has a replaceable water filter, swap it out according to the manufacturer's schedule — usually every three to six months, depending on your water hardness. A clogged filter slows ice production and lets minerals accumulate inside the machine. If you do not have a filter yet and your water is hard, consider adding one; it extends the life of the machine and improves ice clarity.

Key Takeaways

  • Empty and rinse the water reservoir weekly with warm water and a soft cloth to prevent bacterial growth.
  • Replace the water filter every three to six months, or more often if you have hard water.
  • Run a cleaning cycle with a commercial ice maker cleaner or white vinegar every month to dissolve mineral deposits inside the machine.
  • Wipe down the exterior and ice basket weekly, and empty the basket after each use to prevent ice from clumping.
  • Never use bleach, abrasive scrubbers, or harsh chemicals, as they damage plastic components and can contaminate ice.

Run a monthly cleaning cycle with vinegar or commercial cleaner

Mineral deposits build up inside the ice-making mechanism over time, especially if you have hard water. Once a month, run a cleaning cycle to dissolve these deposits before they clog the machine. Fill the reservoir with a commercial ice maker cleaner (brands like Affresh and Ice-O-Matic make them) or white vinegar diluted with equal parts water. Check your manual for the exact ratio — some machines have a dedicated cleaning mode you set up before running the cycle.

Let the cleaning solution run through the machine until the reservoir is empty. Do not interrupt the cycle. After it finishes, empty the ice basket and discard any ice made during the cleaning run. Refill the reservoir with fresh water and run two or three more cycles to rinse out all traces of cleaner or vinegar. Taste the first batch of ice from the rinse cycles — if it tastes like vinegar, run another cycle.

Wipe the exterior and ice basket weekly

The outside of the machine collects dust and fingerprints. Wipe it down once a week with a damp cloth and dry it when ready to prevent water spots. Pay attention to the vents on the sides and back — dust blocks airflow and makes the compressor work harder. Use a soft brush or the brush attachment on a vacuum to gently remove dust from the vents.

The ice basket should be emptied and rinsed every time you use the machine. Ice left sitting in the basket absorbs odors from the freezer and can clump together. Wash the basket with warm soapy water, rinse it thoroughly, and dry it before putting it back. If ice has stuck to the basket, soak it in warm water for a few minutes to loosen it — do not chip it off with a hard object.

Descale the machine if ice production slows

If your ice maker suddenly produces less ice or makes smaller cubes than usual, mineral scale is likely blocking the water lines. This happens faster in areas with hard water. Use a commercial descaling solution made for ice makers, or make a stronger vinegar solution — one part vinegar to one part water. Pour it into the reservoir and run a full cleaning cycle as described above.

If the machine still runs slowly after descaling, the scale may be too thick to dissolve. Contact the manufacturer for a service recommendation; some machines have internal components that need professional cleaning. Do not try to disassemble the machine yourself, as this voids the warranty and can damage the refrigeration system.

Store the machine properly during off-season

If you use the ice maker seasonally or plan to store it for more than a month, clean it thoroughly before putting it away. Run a full cleaning cycle, empty the reservoir completely, and leave the lid open so the interior dries fully. Store it in a cool, dry place — not in a damp basement or garage, where mold can grow inside.

When you take the machine out of storage, run two or three cycles of fresh water through it before using the ice. This flushes out any dust or mold that may have accumulated. If the machine sat unused for more than three months, replace the water filter before using it again.

What to avoid when cleaning

Never use bleach, ammonia, or harsh chemical cleaners on an ice maker. These can damage plastic parts, corrode metal components, and leave residue that contaminates the ice. Do not use abrasive scrubbers, steel wool, or scouring powder on any surface — they scratch the plastic reservoir and the interior walls.

Do not pour cleaning solutions directly into the ice-making chamber or try to clean internal parts by hand. The machine is designed to run cleaning solutions through its own system. Poking around inside can break delicate components and expose you to electrical hazards. Stick to cleaning the reservoir, filter, basket, and exterior only.

Frequently Asked Questions

How often should I clean my countertop ice maker?

Empty and rinse the water reservoir weekly. Run a full cleaning cycle with vinegar or commercial cleaner once a month. Wipe the exterior and ice basket every time you use the machine. In areas with very hard water, you may need to descale every two weeks instead of monthly.

Can I use regular vinegar to clean my ice maker?

Yes, white vinegar works well for cleaning and descaling. Mix it one-to-one with water and run it through a cleaning cycle. Avoid vinegar with added flavors or colors. After the cycle finishes, run two or three cycles of fresh water to rinse out the vinegar smell completely.

Why does my ice taste bad or smell like plastic?

New machines sometimes have a plastic smell that goes away after a few cleaning cycles. If the taste or smell persists, the water filter may be clogged or the reservoir may need deeper cleaning. Run a full cleaning cycle with vinegar, then rinse thoroughly with fresh water cycles. If the problem continues, replace the water filter.

What should I do if the ice maker stops making ice?

First, check that the water reservoir is full and the machine is plugged in. Run a descaling cycle to clear mineral buildup in the water lines. If ice production does not improve after descaling and rinsing, the compressor or water pump may need service. Contact the manufacturer for repair options.

Is it safe to use the ice maker right after cleaning?

After running a cleaning cycle with vinegar or commercial cleaner, you must rinse the machine thoroughly. Run two or three cycles of fresh water and discard the ice from each cycle. Taste the ice from the final rinse cycle — if it tastes clean, the machine is ready to use. If it still tastes like vinegar, run one more water cycle.
