Possible Causes
How to Fix / Troubleshooting
Safety: Unplug the wine cooler before defrosting or accessing the evaporator. Do not use sharp tools to remove ice.
Steps:
- Manual defrost: Remove all bottles, unplug the unit, and leave the door open until all ice has melted. Place towels to catch water.
- Check door seal: Inspect the gasket for gaps or damage. Replace if necessary to prevent moist air entering.
- Test defrost components: After defrosting, access the evaporator and test the defrost heater and sensor as described for E4.
- Reduce door openings: In very humid environments, limit door openings and ensure the door is not left ajar.
Action: Replace any failed defrost components with Zanussi-compatible parts. If ice buildup returns quickly despite good components and seal, consult a technician.
