Possible Causes
Open or shorted heating element, failed temperature sensor (NTC), wiring issue to heater, failed heater relay on control
How to Fix / Troubleshooting
Safety first: Unplug the washer and turn off water supply. Heating components are high voltage; do not test live circuits unless trained.
Step-by-step:
- Access heater and sensor: Remove the rear or lower front panel (depending on model). Locate the heater at the bottom of the tub and the temperature sensor nearby.
- Inspect wiring: Check for burnt or loose connections at the heater and sensor.
- Check for leaks: Look for water traces around the heater seal that could cause shorts.
- Component replacement: If the heater is visibly damaged or the sensor is cracked, replace the faulty part with the correct Maytag heater or NTC sensor.
- Control check: If heater and sensor are good but F23 persists, the main control heater circuit may be faulty and require replacement.
