E4
Display shows E4 and the unit stops cooling; fan may still run.
Condenser Temperature Sensor Failure
E5
Unit displays E5 and does not start ice-making cycle; compressor may not run.
Compressor Overload / High Temperature Protection
E6
E6 appears on the display and the ice maker stops mid-cycle; ice may be partially formed.
Ice Full Sensor / Infrared Beam Fault
E7
Display shows E7; unit may power on but no ice is produced and the water pump does not run.
Water Pump Circuit Failure
E8
E8 error appears; unit may start but shuts down quickly, often with no compressor operation.
Main Control Board Communication / Internal Fault
E9
E9 is displayed and the ice maker stops; fan may run but no ice is produced.
Low Refrigerant / Evaporator Frost Fault (Detected by Sensor Logic)
H1
Display shows H1 and ice production is suspended; unit may still power on.
High Ambient Temperature Protection
ICE
Display flashes ICE or ice-full icon; unit stops making ice even though bin is not full.
False Ice Bin Full Detection
LO
Display shows LO or low water icon; unit beeps and stops making ice.
Low Water Level Detected
Symptom
Display is on but buttons do not respond; unit stuck in one mode.
Keypad Failure / Stuck Buttons
Symptom
Display works but shows incorrect indicators (e.g., wrong mode, random segments lit).
Display Board Malfunction
Symptom
High-pitched squealing or chirping noise while the fan is running.
Worn or Dry Fan Motor Bearings
Symptom
Ice bin overfills and ice spills out even when bin is full.
Ice Level Control Failure
Symptom
Ice cubes are cloudy or white instead of clear.
High Mineral Content or Aerated Water
Symptom
Ice cubes are fused together in large clumps in the bin.
Excessive Melt and Refreeze in Bin
Symptom
Ice cubes are very small or hollow; ice melts quickly in the bin.
Insufficient Water Flow to Evaporator
Symptom
Ice cubes have a bad taste or odor.
Contaminated Water Path
Symptom
Ice maker interior surfaces frost over excessively.
Excessive Frost / Humidity Ingress
Symptom
Ice maker is leaking water inside the cabinet; ice bin is wet and slushy.
Poor Drainage / Meltwater Management Fault
Symptom
Ice maker is leaking water onto the counter or floor.
Water System Leak or Overflow
Symptom
Ice maker produces ice but cubes are irregularly shaped or stuck to the evaporator.
Improper Harvest / Evaporator Coating Issue
Symptom
Ice maker produces ice very slowly; ice cycles take much longer than normal.
Reduced Cooling Capacity / High Head Pressure
Symptom
Ice maker runs but produces no ice at all; evaporator plate does not get cold.
Compressor or Sealed System Failure
Symptom
Ice maker runs continuously without cycling off even when bin is full and ice is present.
Control Logic or Sensor Stuck in Demand Mode
Symptom
Ice maker starts a cycle then shuts off after a few minutes without making ice.
Thermal Protection or Sensor Misread
Symptom
Ice maker vibrates excessively or rattles against the counter or cabinet.
Cabinet Vibration / Leveling Issue
Symptom
Ice maker will not power on at all; no lights or display.
No Power / Electrical Supply Failure
Symptom
Loud grinding or rattling noise during ice-making cycle.
Mechanical Obstruction or Failing Motor
Symptom
Unit frequently stops with ice partially formed and then restarts later.
Intermittent Power or Overheat Cycling
Symptom
Unit trips the household circuit breaker or GFCI when it starts.
Electrical Short or Ground Fault
Symptom
Water pump runs but no water reaches the evaporator.
Airlock or Blockage in Water Circuit
Symptom
Water remains on the evaporator and does not drain properly after harvest.
Evaporator Drainage / Tilt Issue
