How to Fix / Troubleshooting
Safety first: Unplug the washer-dryer before opening any panels. Only qualified persons should work on live circuits.
- Verify outlet: Test the wall outlet with another appliance or a voltage tester to confirm power is present.
- Inspect power cord: Check for cuts, burns, or crushed sections. Replace the cord if damaged.
- Access main PCB: Remove the top or rear cover to locate the main control board. Look for an inline fuse or board-mounted fuse. If blown, identify and correct the cause (shorted component) before replacing.
- Check connectors: Ensure the main power connector from the cord to the PCB is fully seated and not burnt.
- Board replacement: If fuses and wiring are intact but the unit remains dead, the main control board is likely faulty and should be replaced.
