Possible Causes

Failed heater relay on control, shorted heater, wiring short to ground, defective temperature sensor causing control shutdown

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.
