Re: diplomat dishwasher
Hi,
That machine should have a switch assembly to select the program and an electro-mechanical timer unit on it. It’s possible that the timer is simply “stuck” (it happens) and needs reset. To do this you will need to remove the furniture door and turn the timer shaft back to the correct position for “off”, from memory.
If you’re not sure about getting the door off then I wouldn’t advise trying it as you are likely to break the lugs that hold it in place.
From the information given it should be a pretty easy fix though.
