The door sensor cannot determine if the door is open or closed.
Possible Causes & Solutions:
Faulty Door Sensor:
The sensor responsible for detecting door status might be malfunctioning.
Misaligned Door:
The door may not be aligned correctly, causing the sensor to misread.
E03: Defrosting Error
There is an issue with the automatic defrosting system.
Possible Causes & Solutions:
Defrost Timer Malfunction:
The timer responsible for the defrost cycle might be malfunctioning.
Faulty Heating Element:
The heating element used during the defrost cycle might not be working.
E04: Fan Motor Error
The fan responsible for circulating air inside the unit isn’t operating correctly.
Possible Causes & Solutions:
Blocked Fan:
Ensure no obstructions are hindering the fan’s movement.
Faulty Fan Motor:
The fan motor itself might be malfunctioning.
E05: Compressor Error
The compressor, vital for the cooling process, isn’t operating as expected.
Possible Causes & Solutions:
Start Capacitor Issue:
The start capacitor gives the compressor the initial jolt to start; it might be faulty.
Overheating Compressor:
Ensure there’s adequate ventilation around the unit.
E06: Lighting Error
Internal lighting system of the wine cooler or refrigerator is not functioning.
Possible Causes & Solutions:
Burned Out Bulb:
The light bulb might need replacement.
Faulty Light Switch:
The switch responsible for the light might be malfunctioning.
E07: Humidity Sensor Error
The unit is unable to correctly measure the internal humidity.
Possible Causes & Solutions:
Faulty Humidity Sensor:
The sensor might be malfunctioning or has come loose.
Environmental Factors:
External humidity or temperature changes can sometimes affect readings.
E08: Voltage Irregularity
The refrigerator or wine cooler has detected an electrical issue or inconsistent power supply.
Possible Causes & Solutions:
Voltage Fluctuations:
Ensure the unit is plugged into a stable power source.
Faulty Power Supply:
The internal power supply components might be malfunctioning.
E09: Water Drainage Error
The unit is unable to drain excess water, usually from the defrost cycle.
Possible Causes & Solutions:
Blocked Drain:
Ensure the drainage system is free of any blockages or obstructions.
Incorrect Installation:
Ensure the unit is leveled correctly to allow water to drain.
E10: Overcooling Error
The internal temperature is getting too cold.
Possible Causes & Solutions:
Thermostat Issue:
The thermostat might be set too low or malfunctioning.
Sensor Error:
The unit might be misreading the internal temperature due to a sensor error.
E11: Undercooling Error
The internal temperature is not reaching the set point.
Possible Causes & Solutions:
Refrigerant Issues:
There might be a leak or insufficient refrigerant in the system.
Compressor Fault:
The compressor might not be working efficiently.
E12: Vibration Detector Error
For wine coolers: the system that ensures minimal vibrations is malfunctioning.
Possible Causes & Solutions:
Faulty Vibration Dampers:
The dampers designed to minimize vibrations might be worn out or faulty.
External Causes:
Other appliances or external factors causing the vibrations.
E13: UV Protection Error
For wine coolers: the UV protection system, typically for units with glass doors, is malfunctioning.
Possible Causes & Solutions:
Door Seal Issues:
Ensure the door seals properly and doesn’t allow external light to enter.
Faulty UV Filter:
The UV filtering mechanism or material might be damaged.
E14: Control Panel Malfunction
The control panel or touch interface isn’t responding correctly or giving false commands.
Possible Causes & Solutions:
Electrical Glitch:
Try unplugging the unit and plugging it back in after a few minutes.
Damaged Control Panel:
The control panel might need repair or replacement.
E15: Circulation Fan Error
The fan that ensures even temperature distribution inside the unit isn’t working efficiently.
Possible Causes & Solutions:
Blocked Fan:
Check if there’s any obstruction preventing the fan from rotating.
Faulty Fan Motor:
The circulation fan’s motor might need replacement.
E16: Wiring or Connectivity Issue
The internal wiring or connectivity has been compromised.
Possible Causes & Solutions:
Loose Connections:
Ensure all internal connectors and wires are securely in place.
Damaged Wiring:
Inspect for any visible wiring damages; seek professional repair if detected.
E17: Noise Level Error
The unit is operating at a higher noise level than expected.
Possible Causes & Solutions:
Compressor Issue:
The compressor might be aging or in need of maintenance.
Internal Components Misalignment:
Check for any loose or misaligned parts causing unnecessary vibrations or noise.
E18: Condenser Coil Issue
The condenser coil responsible for dissipating heat is malfunctioning.
Possible Causes & Solutions:
Dirt or Dust Accumulation:
Clean the condenser coil to ensure efficient heat dissipation.
Faulty Fan:
Ensure the fan assisting the condenser coil is functioning properly.
E19: Evaporator Coil Issue
The evaporator coil, crucial for the cooling process, is not functioning as expected.
Possible Causes & Solutions:
Ice Build-up:
Ensure there’s no ice accumulation around the coil affecting its efficiency.
Refrigerant Leak:
The coil might not be cooling due to a refrigerant leak; seek professional assistance.
E20: Ambient Temperature Sensor Fault
The sensor detecting room temperature for efficient operation is malfunctioning.
Possible Causes & Solutions:
Faulty Sensor:
The ambient temperature sensor might need repair or replacement.
External Factors:
Sudden changes in room temperature might affect readings temporarily.
