Miele Dryer F66 Error Code
What it means
The dryer airflow is restricted, most often because the lint filters or plinth/toe-kick filter are dirty, wet, damaged, or airflow around the dryer is obstructed.
Try this first
- Clean the lint filters after every drying program and clean the plinth filter whenever the filter symbol or cleaning prompt appears.
- If washing the lint filters, dry them thoroughly before reinstalling; wet filters can cause further drying faults.
- Clean the plinth/toe-kick filter thoroughly, squeeze out the water, and let it air-dry if necessary; do not reinstall it dripping wet.
- Inspect the heat exchanger for visible lint. Do not touch the sharp cooling fins; if vacuuming, use a dust brush lightly so the fins are not bent or damaged.
- Reduce the load if the drum is overloaded and remove anything blocking the ventilation grille below the door.
- For condenser dryers in a small or warm room, open a door or window while drying to provide ventilation.
- If the plinth filter has white detergent residue, wash the filter by itself with no detergent at a maximum 105 F (40 C) and 600 rpm.
- Replace a deformed, torn, or damaged plinth filter that no longer sits flush.
- If the fault remains after these checks, contact Miele Service.
