Miele Dryer Error Codes — Complete List

Miele tumble dryers split cleanly into two worlds. F66 and the "Clean out airways" light are the codes owners actually see — both mean the lint filters or the plinth filter in front of the heat exchanger need cleaning, a genuine DIY job. Everything else documented for owners (F3, F36, F39) is an electronic or sensor fault with Miele's own instruction to call service.

• F3 F3 on a Miele tumble dryer means the drying-air temperature sensor is short-circuited — a technical fault Miele says can't be fixed at home.
• F36 F36 means Miele can't see proof the door is shut — the door contact (reed switch) is faulty, a technical fault for a technician.
• F39 F39 is the dryer's electronic-fault flag — Miele's page just says 'there is an electronic fault' and that it can't be remedied at home.
• F66 F66 is the dryer saying its airflow is choked — and Miele's own page says the cause is usually the lint filters or the plinth filter needing a proper clean.
• Clean out airways light (Clean out airways) The 'Clean out airways' light is the dryer's polite nudge that the lint filters or the plinth filter in front of the heat exchanger need a proper clean.
