Miele Dryer Error Code F10 — Intake Air Restriction / Blocked Vent
What this means
The F10 error code on Miele dryers means the machine has detected restricted airflow. This is most commonly caused by a clogged lint filter, a blocked exhaust vent duct, or a crushed vent hose. Restricted airflow reduces drying efficiency and can cause overheating. Miele dryers have built-in airflow monitoring that triggers this alert before a safety shutdown.
Alternate codes: F 10
Step-by-step fix
4 stepsClean the lint filter thoroughly
Remove the lint filter and clean it under running water with a soft brush. Fabric softener residue creates an invisible film that blocks airflow even when the filter appears clean. Let it dry completely before reinserting.
Hold the filter under running water — if water pools on the mesh instead of flowing through, fabric softener film is present.
Clean the exhaust vent duct
Disconnect the dryer from the vent duct at the back. Use a dryer vent brush kit to clean out lint from the entire duct run to the outside vent hood. Also clean the vent hood flapper.
Dryer vent fires are a leading cause of house fires. Annual vent cleaning is essential, especially for long duct runs.
Check for a crushed or kinked vent hose
Inspect the flexible transition hose between the dryer and the wall vent. Make sure it is not crushed, kinked, or compressed by the dryer being pushed too close to the wall.
Use rigid or semi-rigid metal vent duct instead of flexible foil. Rigid duct provides better airflow and is less prone to lint accumulation.
Verify the vent hood operates freely
Go outside and check the vent hood. The flapper should open when the dryer runs and close when it stops. If the flapper is stuck shut by ice, bird nests, or debris, clear the obstruction.
Install a vent cover with a floating ball seal instead of a flapper — they are less prone to sticking.
When to call a professional
If you cannot reach or clean the full vent duct run (especially long or multi-turn installations), hire a professional dryer vent cleaning service.
