I apologise in advance as I'm touching on that delicate topic of exploding drums, but I'm a bit concerned. A friend of mine has a servis washing machine, one of the final models before its demise in 2008. So I was looking inside the drum (the one with 4 paddles) and couldn't find a seam in the drum; its hidden under a paddle. I also remember, before I became a member, seeing a pic of an exploded servis (or its equivalent). Could anyone tell me if they know whether the drum is screwed or welded? Thanks
