How to Fix / Troubleshooting
Safety first: Ensure the appliance is unplugged before opening any panels. Mains voltage is dangerous.
- Check outlet: Test the wall socket with another appliance to confirm power is available.
- Inspect plug and cord: Look for damage, burns, or loose connections at the plug.
- Check household protection: Reset any tripped breakers or replace blown fuses with the correct rating.
- Internal checks (advanced): Remove the top cover and inspect the mains filter module and wiring for burns or loose connectors. Replace a damaged mains filter.
- Control board: If power reaches the control board but there is no response, the board's power supply may have failed and requires professional replacement.
