Possible Causes
Low or unstable supply voltage, Loose power cord connection, Faulty mains filter (EMI filter), Internal power supply fault on main PCB
How to Fix / Troubleshooting
Safety first: Switch off and unplug the washer before inspecting electrical components.
- Check outlet: Verify the wall socket provides stable voltage using a suitable tester. Avoid using long extension cords or multi-plug adapters.
- Inspect power cord: Check for cuts, burns, or loose plug pins. Replace the cord if damaged.
- Examine mains filter: Access the mains filter module where the power cord enters the washer. Inspect for burn marks or bulging components. Replace if visibly damaged.
- Avoid overloading circuit: Ensure the washer is on a dedicated circuit where possible.
- PCB power supply: If external causes are ruled out and E18 persists, the internal power supply on the main PCB may be faulty and should be serviced or replaced by a professional.
