I have a T701 that has suddenly and without warning started making thumping noises as the drum rotates. I rotated the drum by hand and you could clearly feel the shaking as the thing turned. So, I am guessing that I need new rollers. Then mid cycle the thumping ceased! I don't think the rollers would have just fixed themselves would they? Seems odd.
I would love to get the service manual for this model (is it the same as the T700?). I am happy to donate to a worthy frothy cause.
