well, bought some aftermarket bearings, this was a difficult job – as the case is solid the drum has to come out of the top, which means everything out then machine on its side to drag drum out on a board. time 8 hrs including fitting bearings. reasemble 5 hrs.start the machine even more noisy. i then took it out again and this time split the inner and outer drum – the spider riveted to the drum was corroded and split on all 3 sides (new machine ordered). over the last 6months i have replaced the door rubber(started to shred), the dampers as the machine was vibrating and finally the bearings! i cannot be sure but i supect that all these were related to the spider breaking down/collapsing. i wrote down a blow by blow list of taking the machine apart if anyone wants help with how you dismantle please ask

I too know the feeling only to well with an infamous Smeg / Bosch washer dryer. The actual fault was interesting by way of how it fails. The expensive door seal rubber had been damaged due to friction burning, that was obvious, as the drum had rubbed the on the door seal or it could have been caused by something getting caught and that is what I first thought. Customer could shine no light on the subject and was typically vague as vague can be. To cut to the chase, the drum spider had not cracked where a drum spider normally cracks which is obvious when the whole plot is dismantled. It was cracked right under the drum `s shaft where the shaft is heat set in the aluminium casting, very difficult to see but none the less that was the problem. To make matters worse the drum dropping only happened with certain types of sizes of loads and there was no loud knocking noises you would normally get when a spider cracks, and neither did the drum, when spun by hand or on spin empty, look the tale tale buckled bicycle wheel effect…..all good fun?
