No, it's definitely a switch of some kind. Turning it a quarter turn starts a programme. Sometimes the cycle completes with an empty machine and sometimes there is a puddle of (rather dirty) water in teh floor of the machine.
I have a secondary problem with the bottom sprinkler arm usually dropping off during a cycle. It seems to snap into place OK but clearly is wearing out. I can't imagine this is causing the main problem. But if anyone has any suggestions I would be grateful. (Or a phone number for Diplomat!).
