Possible Causes
Blown mains fuse or tripped breaker, Faulty power cord or plug, Defective mains filter / interference suppressor, Failed main control board power supply
How to Fix / Troubleshooting
Safety first: Do not open live electrical parts. Always unplug before removing panels.
- Check outlet: Test the wall socket with another appliance to confirm it has power. Reset any tripped breakers or RCDs.
- Inspect power cord: Check the dishwasher's power cord and plug for damage, burns, or loose connections.
- Door fully closed: Ensure the door is properly closed; some models will not power the display if the door switch is open.
- Internal checks (advanced): Remove the lower front or side panel to access the mains filter and wiring. Check for burned components or loose connectors. If the mains filter is visibly damaged, replace the mains interference filter. If power reaches the control board but it remains dead, the main control board likely needs replacement.
