Please help. The machine is not drying well. When drying cycle is set to Dampness Level it runs for hours. I had to manually turn it off after 10 hours and clothes still came out damp (not dripping wet but damp) and I could see a bit of water (a few milimiters) left at the bottom of the door's grey rubber ring. If I use a drying cycle based on time, say 60 minutes, clothes also come out damp/wet. I've read about similar problems on this board but I'm still not sure how to proceed. Do I need to look at the Condenser or Filter? I have no idea how to do this and would really appreciate some detailed advice on where/how to address the problem. The machine is under a year old -- should I simply call out an engineer? Many thanks and Merry Christmas to all.
