Error codeF4
ApplianceDryer
Quick answer
Miele tumble dryer fault F4: an open circuit at the drying air temperature sensor. A technical fault that needs a repair appointment.
Model compatibility
Miele reuses codes across series and model years, so F4 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What thiscode means
Miele dryer code F4 indicates an open circuit at the drying air temperature sensor.
Display code F4 on a tumble dryer refers to an open circuit at the drying air temperature sensor.
Reading the F4 message
Support information labels it a technical problem, and the owner cannot remedy it.
How to proceed
Set up a repair visit, as Miele advises. Until then, the dryer should stay off.
Other codes worth a look
Next to it sits F3, a short circuit at the drying air temperature sensor. Compare F40, another electronic module fault. Then there is F43, a model type that is not programmed or an incorrect variant.
