Display shows F8 and the wine cooler may not cool; compressor does not run even though the unit has power.

Safety first: Unplug the appliance before cleaning or accessing the rear compartment. The condenser and compressor can be hot.

F8 is often related to overheating in the condenser area or a high-pressure condition.

• 1. Check installation and ventilation:
  • Ensure the wine cooler has the required ventilation clearances specified by Miele.
  • Verify that front and rear ventilation grilles are not blocked by cabinetry or objects.
• 2. Clean the condenser:
  • Remove the lower front grille or rear panel to access the condenser coil.
  • Use a soft brush and vacuum to remove dust and lint from the condenser fins.
• 3. Inspect condenser fan:
  • Locate the condenser fan near the compressor.
  • Check that the blades spin freely and are not obstructed.
  • If the fan does not run when the compressor should be on (after restoring power), suspect a failed fan motor.
• 4. Check condenser sensor or high-pressure device:
  • Some Miele models use a condenser temperature sensor or high-pressure switch.
  • Inspect wiring and connectors for damage.
• 5. Replace faulty parts:
  • If the condenser fan motor is seized or open-circuit, replace it with the correct Miele fan motor.
  • If the condenser sensor is defective (open/short), replace it with the specified Miele sensor.
• 6. Reset and test:
  • After cleaning and repairs, unplug the unit for 10 minutes to reset the control.
  • Restore power and monitor operation. If F8 returns quickly, a sealed-system or control board issue may exist and requires a professional technician.
