How to Fix / Troubleshooting
Safety first: Only qualified persons should work on live electrical circuits. Disconnect power before opening panels.
- Check supply: Verify that the circuit breaker or fuse feeding the dishwasher has not tripped. Reset or replace if necessary.
- Inspect mains cable: Check the power cord and plug (if fitted) for damage.
- Terminal block: Open the electrical connection box and ensure all phase and neutral wires are tight.
- Test power switch: Use a multimeter to confirm that the on/off switch passes voltage when turned on. Replace if faulty.
- Control board: If supply is present but the display remains off, the main PCB may be defective and require replacement.
