How to Fix / Troubleshooting
Safety first: Turn off the circuit breaker and unplug the appliance. Work only if you are comfortable with mains electrical safety; otherwise contact a technician.
- 1. Confirm outlet power: Test the wall socket with another appliance to ensure it is live.
- 2. Inspect power cord: Check the cord for cuts, burns, or kinks. Ensure it is firmly seated in the rear socket (if detachable).
- 3. Access mains filter and module: Remove the top or rear panel to locate the mains filter and power module. Look for an accessible fuse on the module; test and replace only with the same rating if blown.
- 4. Check connections: Verify that all connectors from the mains filter to the power module and from the module to the UI are secure.
- 5. If still dead: A failed power module or UI board is likely. These are complex, high-voltage parts; replacement is best handled by an authorized Gaggenau service provider.
