I have a creda t622 condenser tumble drier. Occasionally I will take out shirts or sheets and they will have black oiliness on them where they have been caught in the mechanism. This does not always happen but when it does it tends to be on collar points and frills
you need a new felt seal at the front,this wears down creating a gap that pinches clothes,some models use bearing pads,oblong pieces of plastic that the drum sits on at the front
