The problem is it keeps filling up and then the anti flood switch brings on the pump and empties out some water then it brings more water in and this will go on all day, can’t blame the water level switch as i can’t find one anyone any ideas????
Common problem and loads of posts on it. Faulty flow sensor ( impellor jug ) Part no 424099. Its fitted at the rear left and is a white cyclindrical object inline with the inlet hose just before it enters the water matrix.
Dont take this the wrong way
but how sure are you this will fix it, because I was just advised a couple of weeks ago to change the programmer which I did and that seemed to fix it at the time, but same problem back again.
