Washer shows F23 and may stop mid-cycle, often associated with temperature issues
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
How to Fix / Troubleshooting
Safety first: Unplug the washer and shut off water supply before accessing rear components.
Step-by-step checks:
- 1. Run a cold wash: Select a cold-only cycle. If the washer completes without F23, the issue is likely in the heating/NTC circuit.
- 2. Access NTC and heater: Remove the rear panel. Locate the heater and NTC sensor at the bottom of the tub.
- 3. Inspect wiring: Check the harness from the NTC and heater to the control for damage or loose connections. Reseat all plugs.
- 4. Test NTC: Disconnect the NTC and measure resistance at room temperature. Compare to the spec in the tech sheet. Replace if open, shorted, or far out of range.
- 5. Test heater: Measure resistance across heater terminals and to ground as described for F07. Replace if open or grounded.
When to call a technician: If both NTC and heater test correctly, the control board may be misreading temperature and should be evaluated by a professional.
