Possible Causes
Burnt relay contacts on control board, Broken solder joints, Internal PCB track damage, Overheated connector
How to Fix / Troubleshooting
Safety first: Isolate the dishwasher from mains power before opening the control housing.
- Access control board: Remove the inner door panel or top cover (model dependent) to reach the main PCB.
- Visual inspection: Look closely at the relay area (usually near the heater and motor outputs). Check for cracked solder joints, burnt relay cases, or discoloured PCB tracks.
- Check connectors: Inspect the high-current connectors for signs of melting or burning. Replace any damaged connectors and associated wiring.
- Board repair or replacement: While some technicians may re-solder or replace relays, the recommended approach for most users is to replace the entire control board with a genuine Iberna part.
Due to the complexity and safety implications, E11 faults are best handled by an experienced appliance technician.
