We have a WMM75 washing machine, now approx 3 years old. About a year ago, the three, light blue, plastic 'beaters' inside the drum started to come off, one by one. I replaced all three with new 'Hotpoint' components from an approved distibuotor. However, the new units started to fail within just a couple of months. The units fail by the small plastic clips on the underside (which hold them to the drum) breaking off. It is not possible to operate without the plastic 'beaters' as the exposed metal fixing points in the drum then rips your clothes. We are now seeing the units fail approx 1 per month which is annoying and getting expensive. I suspected a bad batch of the components but the manufacturer and distibutor say that there is nothing wrong with the replacements supplied and are blaming 'wear and tear'. We don't wash shoes or trainers in the machine so I'm at a loss as to why this is happening. Does anyone know if this has been seen before?
