My faithful tumble drier’s started letting us down! It just stops and beeps about 15-20 minutes into the cycle. It’s not showing any fault lights, I’ve cleaned the obvious filters and condensator and checked the door switches but I’m not sure what else a layman can do.
Would advise you to replace float switch on condensate receptacle, am only guessing here as to what may be the issue from past experience on this model, you may be best advised to get engineer to check it for you as you could end up going through a few parts before getting it sussed.
