Whirlpool undercounter ice maker makes thin, slushy, or wet ice that melts quickly

Safety: Unplug the unit before adjustments.

• Check water temperature: Ensure the supply is cold water. Hot water lines will reduce ice quality.
• Adjust water level (if applicable): Some Whirlpool models have a water level adjustment screw on the reservoir float. Follow the tech sheet to set the correct level so the evaporator plate is properly covered but not overflowing.
• Inspect evaporator thermistor: Verify it is firmly attached to the evaporator and not loose. Replace if readings are out of spec.
• Run a test cycle: After adjustments, run a full cycle and observe freeze time. If ice remains slushy, further diagnosis of the control board may be required.
