How to Fix / Troubleshooting
Safety first: Before opening the appliance, ensure the circuit breaker is off. Only work on live circuits if you are qualified.
- 1. Check external power: Verify that the wall outlet has power by plugging in another device. Reset any tripped breakers or RCDs.
- 2. Inspect power cord: Check the Brandt dishwasher's power cord for cuts, burns, or loose connections at the terminal block.
- 3. Test mains filter: Access the base and locate the mains filter module. Check for burnt smell or visible damage. Replace if faulty.
- 4. Control board supply: If the mains filter is good, the internal low-voltage power supply on the control board may have failed. Replace the electronic control board if there is no low-voltage output.
