Machine is 12 years old and recently started making intermittent noises which appear to be getting progressively worse. Recently after finishing a spin cycle, when the front door was opened, a small amount of smoke came out. On investigation the noise appears to come from the drum binding/rubbing on boot during a portion of every rotation. If I lubricate the rubber seal where it meets the drum with house hold detergent - then the noise goes away and the drum rotates smoothly. During a normal cycle it seems to make friction noise when rotating whenever water is not present in the drum. Appears not to be related to load. I removed the front door bellows and inspected the rubber seal - it appears OK with no visual sign of abrasion. Without the bellows attached, I put the machine through a long spin cycle - all was quiet and smooth. Drum seems equally spaced around the outer casing. The Drum seems solid with no wobble. When I re assembled, the drum and the boot seem to sit OK with nothing obviously sagging. However the drum still binds on the boot for a small portion of a rotation. I hesitate to change door bellows without understanding the root cause of problem - cause I wont have any change out of $100, and not sure the problem wont still be there.
Any help appreciated
