I replaced the Float Valve Assembly. Unfortunately, it took me longer because the switch was behind the front base as opposed to being in front like later models. I wasn't able to slide the dishwasher out so I had to use a mirror to look at the switch float with the flashlight from my phone. How did the float assembly need to reassembled, I don't know. In any event, I reassembled the float Switch switch Float and replaced the float assembly and it worked fine. Btw your customer service people are amazing.
