What does it mean when my Whirlpool Hybrid Electric Heat Pump Water Heater displays “ICE” on the user interface?

CAUTION: Before attempting any corrective actions, ensure the power to the water heater is turned off at the circuit breaker/fuse box to ensure your safety.

INDICATES: Heat pump is in defrosting cycle.

What To Do: No action is necessary. The “ICE” diagnostic code indicates that the heat pump is currently in a defrosting cycle. This is a standard procedure to ensure the system functions efficiently, especially in colder conditions. The water heater will automatically resume its normal operation once the defrosting cycle is complete.
