Ice cubes are hollow, very small, or melt quickly in the bin.

Safety first: Use only potable, cool water in the reservoir.

• Adjust ice size: Set the ice size to medium or large to extend the freeze time.
• Use cooler water: Fill the reservoir with cold tap water instead of warm water to reduce cycle time.
• Clean evaporator: Mineral buildup on the evaporator can reduce heat transfer. Turn off the unit, drain water, and clean the evaporator plate with a soft cloth and a 1:1 vinegar-water solution. Rinse thoroughly.
• Sensor check: If cubes remain hollow even on large setting, the evaporator thermistor or control board may be misreading temperature and should be tested and replaced if necessary.
