She needed a new dishwasher anyway, but kinda embarrassing to have the installer find the problem.

Yeah. I've got one of those switches in my kitchen. Totally unmarked and they never actually told me what it does. I turned on everything and turned it off to see what happened.

There is also one in my garage that for some bizarre reason actually turns off the washing machine and the freezer sockets. Not quite sure why they're wired like that.
