How to Fix / Troubleshooting
Safety First: Unplug the washer and allow any hot water to cool before working near the heater.
Step-by-step checks:
- Test heater and NTC: Follow the procedures in F03 and F07 to verify the heater and temperature sensor are within specification and not shorted to ground.
- Inspect wiring: Check the heater wiring harness for chafing against the tub or cabinet that could cause shorts.
- Control inspection: Examine the main control board for signs of a burnt heater relay or damaged traces.
When to replace: Replace any shorted heater or damaged wiring. If components are good but F15 persists, replace the main control board.
