Washer displays F23 and may stop heating or abort cycle; often related to temperature sensing.

Safety Warning

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 or open NTC sensor, wiring short to heater, failed main control temperature circuit

How to Fix / Troubleshooting

Safety first: Unplug the washer. Heating and sensor circuits can carry hazardous voltage when powered.

Check NTC and wiring:

Follow the NTC location and testing steps in the F05 procedure.
Inspect the wiring harness from the NTC to the control board for chafing or shorts, especially where it passes near the heater terminals.

Corrective action: Replace the NTC sensor if resistance is out of specification or intermittent when gently wiggling the wires. If sensor and wiring are good, the control board may misread the temperature and require replacement.
