How to Fix / Troubleshooting
Safety First: Internal temperature sensors are wired to mains-powered circuits. Turn off power at the breaker before any internal inspection.
- Confirm symptom: F6 appears early in the cycle and water may not heat properly.
- Power reset: Turn off the breaker for 5 minutes, then restore power and run a short cycle to see if the error reoccurs.
- Check for obvious damage: Without removing panels, inspect the interior for signs of overheating or melted plastic, which would require immediate professional service.
- When to call for service: F6 almost always requires testing the NTC sensor and wiring with a meter and replacing the faulty component or control board. This should be done by a qualified technician.
