We've had out heatpump tumble dryer about 18 months and it's been fine until recently.
Now, rather than the lint filter collecting all the lint, the lint filter seems to stay pretty clear and the lint just accumulates round the door and on the clothes.
Yes, the lint filter is cleaned regularly, and yes, the heat exchange filters gets cleaned regularly.
Any ideas what to check next?
Hey @AJUK, are you still having issues with this? Can you share the model number of the heat pump dryer? This should be on a label on the inside door. Also, is there any error message displayed on the screen of the machine?
