Drying became very slow, or laundry comes out half-dry
The #1 cause by far: the filter system is clogged — the double lint filter in the door, and the plinth filter in front of the heat exchanger. Lint that slips past them builds on the exchanger itself and chokes the heat pump.
clean the door filters after every load, and wash the plinth filter with its sponge under running water — dry it fully before refitting. Still slow = the exchanger needs a deep clean with our equipment, or the heat-pump circuit needs a check.
