Bosch Classixx 1200 Express Drum Stability

I've made a video of the problem. I'm an electronics engineer, so not daft.

I've checked the springs which seem fine, as do the dampeners. The concrete also seems stable. I did recently move home and ever since the machine has been incredibly noisey which has gotten progressively worse/developed into a knocking noise.

Is it the bearings? Can I fix it? Any help appreciated as I don't really have a clue. I've replaced the brushes but apart from that it's never failed me over the last 16 years.

Cheers

Can you reproduce the knocking noise with machine unplugged and shaking drum around? Or moving cabinet from side to side.

Hi, Those Classixx w/ms are known for the spider to fracture an arm... Take a look on youtube for some examples. Also how to replace a spider (the rivets have to be drilled out and replaced with bolts) It's quite a job as the outer drum has to be split open, but repair kits are available, depends how hands-on you are.

Yes Tracing noises like that is a matter of shaking it about and seeing where the noise is coming from. Something is loose.

Yeah I can replicate it, kind of, the sound comes from the back of the unit but only when it has any sort of load inside it - it sounds like the bearing but it's completely stable when it's empty. I'm going to remove the rear guard tomorrow and take a closer look.
