Possible Causes
Unstable mains voltage, Loose power cord connection, Faulty noise filter (EMI filter), Defective main control board power supply section
How to Fix / Troubleshooting
Safety first: Unplug the washer before inspecting the power entry components. Do not work on live circuits.
- 1. Check outlet and plug: Ensure the washer's plug is fully inserted into a properly grounded outlet. Avoid using extension cords or power strips.
- 2. Test outlet: Plug in another appliance to confirm the outlet has stable power. If lights flicker or power drops, contact an electrician.
- 3. Inspect power cord: Look for cuts, burns, or kinks in the power cord. Replace if damaged.
- 4. Access EMI filter (advanced): Remove the rear or top panel to locate the noise filter / EMI filter module where the power cord enters the washer. Check for burnt smell or discoloration. Replace if faulty.
- 5. Main PCB check: If E30 persists with good supply and EMI filter, the main control board's power supply circuit may be defective and require replacement.
