How to Fix / Troubleshooting
Safety first: Unplug the appliance.
Basic checks:
- Verify heater and NTC: Confirm that the dryer heater and NTC sensor are functional (see F13 and F14 steps). If both are good, focus on the control.
- Inspect control board: Remove the top cover and inspect the main control for burnt areas near the dryer relay.
Resolution: If the board shows damage or F15 persists despite good heater and sensors, replace the main control board.
