E7
Display shows E7; condenser fan at the rear may not run, cabinet gets warm, and compressor runs hot.
Condenser Fan Motor Error
E8
Display shows E8; temperature cannot be adjusted or setpoint changes are not accepted.
Control Panel / Touch Keypad Error
E9
Display shows E9; unit may shut down or run continuously, and temperature readings are clearly incorrect.
General Sensor Circuit Error / Multiple Sensor Fault
Symptom
Clicking noise every few minutes from the rear of the wine cooler; unit struggles to cool.
Compressor Overload Cycling
Symptom
Display is completely blank; wine cooler does not respond, but mains outlet has power.
No Power to Control / Dead Main PCB
Symptom
Display works but buttons or touch controls do not respond to input.
Unresponsive Control Panel
Symptom
Door alarm beeps frequently even though the door appears closed and cooling is normal.
False Door-Open Alarm
Symptom
Dual-zone Siemens wine cooler: one zone cools correctly while the other remains warm.
Single-Zone Cooling Failure in Dual-Zone System
Symptom
Excessive condensation on the glass door or inside walls of the Siemens wine cooler.
High Humidity / Door Seal Issue
Symptom
Excessive frost or ice buildup on the back wall or around the evaporator inside the wine cooler.
Defrost System Failure
Symptom
High-pitched squealing or chirping noise from inside the wine cooler.
Evaporator Fan Bearing Wear
Symptom
Interior light not working, but the wine cooler otherwise cools normally.
Interior LED / Door Switch Failure
Symptom
Loud humming or buzzing noise from the rear of the wine cooler during operation.
Compressor or Condenser Fan Noise
Symptom
Rattling or clinking noise inside the cabinet when the compressor or fan runs.
Internal Shelf or Bottle Vibration
Symptom
Strong chemical or burning smell coming from the rear of the wine cooler.
Overheating Electrical Component
Symptom
Unusual chemical or solvent-like odor inside the cabinet that does not dissipate.
Plastic Component Off-Gassing or Contamination
Symptom
Vibration transmitted to surrounding cabinetry; nearby objects rattle when the wine cooler runs.
Installation / Leveling Vibration Issue
Symptom
Warm air or moisture felt around the door frame; door does not seem to seal properly.
Door Gasket Failure / Door Misalignment
Symptom
Water pooling at the bottom inside the cabinet or leaking onto the floor in front of the wine cooler.
Condensate Drain Blockage or Leak
Symptom
Wine cooler interior temperature fluctuates widely; bottles alternate between too warm and too cold.
Unstable Temperature Control / Airflow Imbalance
Symptom
Wine cooler not cooling at all; interior is at room temperature but lights and display work, no error code shown.
Compressor Not Running
Symptom
Wine cooler overcools; temperature inside is much lower than setpoint and bottles may be too cold or freezing.
Thermostat / Sensor Miscalibration
Symptom
Wine cooler runs but does not reach set temperature; only slightly cool inside.
Reduced Cooling Capacity / Refrigerant Loss
Symptom
Wine cooler runs continuously without cycling off, even when interior feels cold.
Continuous Run / Control or Sensor Fault
Symptom
Wine cooler short cycles; compressor turns on and off frequently in short intervals.
Short Cycling / Control Instability
