Washer shows F37 and may not heat water correctly

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

Shorted NTC sensor, wiring short to ground, control board input fault

Safety first: Unplug the washer before testing the sensor.

Step-by-step checks:

1. Access NTC: Remove the rear panel and locate the NTC at the heater area.
2. Inspect wiring: Look for damaged insulation or wires touching the metal tub.
3. Test NTC: Measure resistance at room temperature. A very low reading (near 0 Ω) indicates a shorted sensor. Replace if shorted.

When to call a technician: If wiring and NTC are good, the control board may be misreading the circuit.
