Miele
Dryer
Code F3
medium severity
Miele models: Miele heat-pump and condenser dryers do not vent externally; condensate drains to a collection tank or a direct-drain connection. The door-opening lint filter is the primary filter, but there is a secondary condenser fluff filter in the lower plinth that must be cleaned monthly. A full condensate tank will pause the cycle without an explicit error.
Common causes
- Heating element failed (most common on electric dryers)
- High-limit thermostat tripped
- Thermal fuse blown
- Restricted airflow caused an overheat that tripped a safety device
Step-by-step fix
- Check the vent duct first — a F3 caused by restricted airflow will recur if the duct is not cleared.
- Test the heating element for continuity — a broken element reads open.
- Test the high-limit thermostat and thermal fuse.
- Replace whichever component is open.
