Washer displays F38 and may not heat or may stop mid-cycle

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Open NTC sensor, broken NTC wiring, loose connector, control board input fault

Safety first: Unplug the washer before accessing the rear panel.

Step-by-step checks:

1. Inspect NTC connector: Ensure the plug is fully seated and not corroded.
2. Test NTC: Measure resistance at room temperature. An infinite reading indicates an open sensor. Replace if open.
3. Check wiring: Follow the harness to the control and repair any breaks.

When to call a technician: If a new NTC and good wiring still result in F38, the control board likely needs replacement.
