Heat-pump dryer shows F50 and does not heat properly.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Low refrigerant charge due to leak, blocked capillary or expansion device, compressor mechanical failure, sensor fault in heat pump circuit

Safety first: Unplug the dryer. The sealed refrigeration system must only be serviced by certified personnel.

User-level actions:

Clean all filters and the condenser thoroughly to ensure maximum airflow across the heat pump.
Ensure the dryer is installed in a room within the recommended ambient temperature range; very cold rooms can impair heat pump operation.
If F50 persists, do not attempt to open the sealed system. Contact a Miele-authorized service provider for leak detection, pressure checks, and refrigerant handling.
