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

Partially failed heater element, Scaled heater reducing efficiency, Faulty NTC sensor reading, Low supply voltage

Safety first: Unplug the washer before internal inspection.

Check water temperature: During a 60°C cycle, feel the door glass after 20–30 minutes. If only lukewarm, heating is slow.
Descale: Run a descaling program with a Miele-approved descaler to remove limescale from the heater.
Inspect heater wiring: Access the heater terminals and ensure all connectors are tight and free of corrosion.
If F19 persists: The heater or NTC may be out of specification and should be tested and replaced by a technician.
