Today I scrapped a Miele Heat Pump drier from 2011, I bought it second hand for $100 and when it arrived, there were no secondary filters and the front of the evaporator was choked with fluff and lint. I cleaned it out but it never managed to dry a load, it would get warm but never hot, it was either worn out from age or abuse.
I stripped it down for parts as everything other than the sealed system is compatible with the 4 others that I have, what amazed me, is how clean the evaporator and condenser were, considering that the front of the evaporator was originally stuffed full of fluff. For those speculating about the fluff forcing itself all the way through, this is what a 13yo abused dryer looks like.
I had only ever cleaned the front, the rest of the unit is as freshly unwrapped.
The evaporator is at the front, the condenser at the back and there is a secondary condenser in front of the compressor, this is used to dump heat into the room to reduce the temp in the airflow and to help improve the condensation of moisture.
Best of all, I dissaessmbled the entire thing, with just the refrigeration system left on the base, all with a single Torx Screwdriver. No other tools needed
