- Disconnect the Power: To ensure your safety, start by disconnecting the power supply to your washer. Unplug the machine or turn off the circuit breaker if needed.
- Check the Connections: Once the power is off, access the back of your washer and locate the ATC thermistor. Inspect the wires and connections for any signs of damage or loosening. Tighten any loose connections if necessary.
- Test Continuity: Using a multimeter, test the ATC thermistor for continuity. If the reading shows an open circuit or a short, it means the thermistor is faulty and needs to be replaced.

If, after following these steps, the F40 error code persists, it may be best to consult a professional appliance repair technician for further assistance. They can accurately diagnose the issue and provide a solution specific to your washer model.
