I have a 4 year old Bosch WFL2450 washing machine that pongs! There's nasty build up of scum in the rubber seal, and with a torch inspection, covers the whole of the outside of the drum. We don't use powder, only liquid and have checked for blockages, all clear. After each wash I have to use to use the mini drain hose to let out the jamjar's worth of water out (which smells) otherwise the machine stinks - it's usually cloudy with bots of scum.
Any ideas?
