Hi I have an Indesit WD 11 Washer-dryer which is playing up. The dial clicks round endlessly and the light flashes eight times. (And after a while flashes 8 times again, etc.) According to another website, which was in reference to a WD 12, 8 flashes refers to a “heater relay cannot be activated” fault. Does anyone understand the problem or know how it can be fixed? Thanks for your help.
