How to Fix / Troubleshooting
Safety: Unplug the washer and avoid repeated power cycling until the fault is diagnosed.
- Inspect door lock coil: Remove the door lock and check for burn marks or melted plastic. Replace if damaged.
- Check harness for shorts: Look for rubbed-through insulation or pinched wires between the lock and control board.
- Control board inspection: Remove the top panel and visually inspect the board for burned components near the door lock output. Do not touch capacitors or live circuits.
Because E43 typically indicates a control-level failure, professional board diagnosis and replacement are recommended.
