E6
Display shows E6 and the interior light or control panel behaves erratically when the door is opened or closed.
Door Switch or Door Sensor Fault
E7
Display shows E7 and the unit fails to maintain set temperature despite the compressor running.
Condenser Fan or Condenser Temperature Fault
E8
Display shows E8 and the compressor does not run; the unit remains warm.
Compressor Drive or Inverter Fault (if equipped)
E9
Display shows E9 and the unit beeps; temperature cannot be adjusted properly.
Control Panel or Keypad Fault
Symptom
Buzzing or rattling noise from the rear, especially when the compressor is running.
Condenser Fan or Condenser Vibration
Symptom
Cabinet exterior sides feel excessively hot to the touch.
Condenser Heat Dissipation Issue
Symptom
Clicking noise from the compressor area and intermittent starting attempts.
Compressor Start Failure
Symptom
Control panel buttons do not respond or respond intermittently.
User Interface Keypad Failure
Symptom
Display is completely blank, but interior light may still work.
Display Power or UI Failure
Symptom
Display shows temperature but does not change even after many hours of operation.
Sensor Stuck Reading or Control Board Fault
Symptom
Door does not close properly or pops open slightly after being shut.
Door Alignment or Gasket Failure
Symptom
Dual-zone wine cooler has both zones at the same temperature despite different setpoints.
Zone Separation or Damper Failure
Symptom
Excessive condensation on the glass door or inside the cabinet.
Moisture Ingress / Poor Insulation
Symptom
Excessive frost or ice buildup on the evaporator or rear interior wall.
Defrost System Failure or Air Ingress
Symptom
High-pitched whine or grinding noise from inside the cabinet.
Evaporator Fan Bearing Wear
Symptom
Interior light does not turn on when the door is opened, but the unit cools normally.
Interior Lighting Failure
Symptom
Interior light stays on even when the door is closed, causing heating inside the cabinet.
Door Switch Stuck Closed
Symptom
Loud humming, rattling, or vibrating noise during operation.
Mechanical Vibration or Loose Components
Symptom
Strong chemical or burning smell coming from the wine cooler.
Overheating Electrical Component
Symptom
Unit trips the household circuit breaker or RCD when plugged in or shortly after starting.
Electrical Short or Ground Fault
Symptom
Unusual sweet or solvent-like odor and loss of cooling performance.
Refrigerant Leak in Sealed System
Symptom
Water pooling at the bottom of the wine cooler or leaking onto the floor.
Condensate Drain Blockage or Overflow
Symptom
Wine cooler cools but temperature is uneven; top is warmer than bottom or vice versa.
Air Circulation Imbalance
Symptom
Wine cooler not cooling at all; interior is at room temperature, but lights and display work.
Complete Loss of Cooling
Symptom
Wine cooler runs continuously and overcools or cannot reach the set temperature, cycling rarely or not at all.
Thermostat / Temperature Control Miscalibration
Symptom
Wine cooler turns on and off frequently in short cycles.
Short Cycling / Control Instability
