After each pass, the very small lint filter must be taught. This is as far as normal. However, the device has another filter behind a service hatch. However, this has to be cleaned after about every 3rd round.
The filter consists of a sponge (one knows vll. From the aquarium) after approximately 1 year use has been excessive wear and no longer properly fit into the mold.
Despite regular cleaning of the channel is already heavily polluted after the 2nd filter. I am afraid that I can not use a long time this dryer. The filter must be changed already.
UPDATE 12/01/2015
Unfortunately, I have to say: The biggest expense in the overall laundering merge and dryer maintenance.
The dryer should decrease work actually.
The customer service of Bauknecht pointed out to me that I should read better before buying the guide would.
There is pointed to the high level of maintenance ....
Did the assessment then reduced to a star.
