The appliance is removing water from the clothes, but not pumping the water up to the drawer. I have tested the pump and it is ok. I suspect the magnetic switch situated in the pump reservoir. Has anyone come across this? Also, there is a non return valve sort of arrangement, consisting of a chrome ball bearing in a tube, which is part of the sump. I’m not sure what this is supposed to do. Can anyone shed any light please? Cheers. Steve.
