KitchenAid KUIC18NNTS3 freestanding ice maker Parts

On the KitchenAid KUIC18NNTS3 freestanding ice maker, we reset the icemaker by turning it OFF, then back ON at the control panel; if the Service light returns after cycling power, the manual directs turning the unit off and back on again and then scheduling service if the light comes back.

Quick reset steps (control panel)

• Press OFF to stop ice maker operation.
• Wait about 30 seconds.
• Press ON to restart ice production.
• If you just installed the unit or it has been off, allow 24 hours for the first batch.
• Discard the first batch of ice produced after startup.

What the lights and buttons mean on this model

The KUIC18NNTS3 uses a control panel with On/Off, Holiday Mode, and Clean/Reset indicators. The On/Off button stops ice production but does not shut off power to the ice maker.

What you see	What it usually means	What we recommend
Ice maker not making ice	Unit is OFF or recovering after restart	Turn ON and allow up to 24 hours
Service light on	The unit detected a condition needing attention	Turn OFF then ON; if it returns, arrange service
Clean/Reset light yellow or red	Cleaning is due or ice production is dropping	Clean the ice making system per the KUIC18NNTS3 owner's manual

If “reset” does not restore ice production

These checks solve the most common no-ice complaints on freestanding ice makers:

• Confirm the ice maker is ON (not in Holiday Mode).
• Verify the water supply valve is fully open and the supply line is not kinked.
• Clean the condenser; restricted airflow reduces ice capacity.
• If the bin is overfilling or shutting off early, the bin temperature sensing can be involved; check the ice maker bin thermostat WPW10503764.
• If the unit is not filling with water, the inlet valve can be involved; check the freestanding ice maker water inlet valve W10585391.

Why it matters

A proper reset gets the control back into a normal cycle, but consistent ice production depends on water supply, airflow across the condenser, and routine cleaning. Keeping those basics in shape prevents slow ice production and nuisance service lights.

Yes. For the KitchenAid KUIC18NNTS3 freestanding ice maker, running a vinegar-and-water solution through the system is a practical way to dissolve mineral scale that can reduce ice production and cause off taste or odor; finish by flushing with multiple fresh-water cycles so no vinegar remains.

Recommended way to clean (safe, effective)

Use the cleaning steps and cycle described in the KUIC18NNTS3 owner's manual. If you are using vinegar as your descaling solution, this approach works well for routine scale removal.

• Turn the ice maker OFF before starting.
• Empty the bin and remove any loose ice.
• Mix a 1:1 solution of white vinegar and warm water.
• Run the unit's cleaning cycle (or circulate the solution through the water system as directed in the manual).
• Let the solution contact internal surfaces long enough to break down scale.
• Drain, then run 2 to 3 fresh-water rinse cycles (more if you still smell vinegar).
• Turn the ice maker back ON and discard the first batch of ice.

What not to use

The manual cautions against harsh or surface-damaging cleaners on the unit.

• Do not use abrasive cleaners on surfaces.
• Do not use chlorine bleach on stainless steel surfaces.
• Do not use sharp tools that can scratch or puncture components.

When cleaning is especially important

Your ice maker is designed to signal when cleaning is due, and scale can directly affect performance.

Symptom	What it often means	What to do next
Ice production drops a lot	Scale buildup in the water/freezing system	Run a cleaning cycle and rinse well
Off taste, odor, or gray ice	Mineral content or scale	Clean the system; consider water treatment
Ice sheet not cutting well	Ice bridging or grid issue	Level the unit; clean; check grid connection

Parts that commonly relate to cleaning and scale issues

If cleaning does not restore normal operation, these model-matched parts are commonly involved in water flow or ice formation.

• Freestanding ice maker water inlet valve W10585391 (controls water fill)
• Ice maker water tubing WPW10217922 (delivers water; can scale or restrict)
• Ice maker bin thermostat WPW10503764 (helps regulate bin temperature)

Why it matters

Regular cleaning helps prevent premature component problems and keeps the ice making system operating efficiently; it also reduces scale-related issues that can cause thin ice, low output, or unpleasant taste and odor.

If your KitchenAid KUIC18NNTS3 freestanding ice maker runs but makes no ice, the most common causes are the control being OFF, no water supply, or a drain problem that keeps the water pan from holding water. Start with power, ON/OFF, water supply, and drain checks from the KUIC18NNTS3 owner's manual.

Quick checks (in order)

• Confirm the control is set to ON.
• Verify the water supply line is connected and the shutoff valve is fully open.
• Make sure the drain cap is tight; a loose cap can empty the water pan and cause thin ice or no ice.
• Check the drain tube and drain hose for debris, twists, or kinks.
• Make sure room temperature is above 55°F (13°C); colder rooms can cause the bin thermostat to shut the unit off.
• If you recently added a lot of water and your model has a drain pump, wait a few minutes for it to clear.

What the symptoms usually mean

What you notice	Most likely issue	What to do next
Unit has power but no ice production	Control OFF or water supply off	Turn control ON; open water valve
Water pan will not stay filled	Drain cap loose or drain issue	Tighten cap; clear/kink-check drain
Ice sheet sticks or ice between plate and grid	Unit not level or needs cleaning	Level the unit; run a cleaning cycle
Stops making ice in a cool space	Room temp below 55°F	Warm the room; recheck operation

Parts that commonly relate to “no ice”

If the basic checks above do not restore ice production, these model-specific parts are often involved:

• Freestanding ice maker water inlet valve W10585391 (controls water fill)
• Ice maker bin thermostat WPW10503764 (monitors bin temperature/ice level conditions)
• Ice maker electronic control board WPW10226156 (controls the ice-making cycle)

Why it matters

This ice maker drains mineral-heavy water after each freeze cycle and refills with fresh water. If the drain is restricted or the water pan cannot hold water (loose drain cap, kinked drain hose), the unit can run without producing a proper ice sheet.
