Hi Dave, I think that’s the sensor I already replaced. Anyhow, I refitted the felt ring around the drum at the rear which had torn apart and fallen off and that seems to have fixed it. I’m annoyed I didn’t do this before spending £100 on parts but we learn! At least it’s working now.
one small thing, when I detached the drum I found a small pin with a moveable T fastener and a spring on the floor. Any ideas where this could have come from?
Thanks for your help.
Cheers Grant
