Miele Dryer Error F20

DIY Fix Basic checks if error appears

1. Turn the dryer off and unplug it from power for at least 2–5 minutes.
2. Confirm that the dryer’s lint filter and airways are clean and unrestricted.
3. Restart the dryer and see if the error persists.

Technician Only Inspect heating circuit components (if F20 is indeed a heating fault)

1. Check internal heating elements, thermostats, and related temperature sensors for continuity and proper function.
2. Inspect wiring between the control board and heater components for damage or loose connections.
3. Use proper diagnostic tools to verify if the heating circuit fails to reach temperature within expected timing.

Parts needed: Heating element, High‑limit thermostat or thermostop, Temperature sensors (NTC)
