Possible Causes

Incorrect supply voltage, loose power cord connection, failing line filter, main control power supply fault

How to Fix / Troubleshooting

Safety first: Turn off the circuit breaker before inspecting power connections. Use a meter only if you are trained to work with live voltage.

Verify supply voltage:

  • Confirm the washer is connected to a dedicated 120 VAC circuit (in North America). Avoid extension cords.
  • Check the outlet for proper voltage and polarity.

Inspect internal power connections:

  • Unplug the washer and remove the top or rear panel.
  • Inspect the line filter and main control board power connectors for loose wires or burn marks.

If the supply and wiring are correct but F40 persists, the main control's power supply section may be defective and the board should be replaced.
