My dishwasher backs directly against an outside wall which is uninsulated. My wife called me at work yesterday to say when she pushed the button it "got warm inside" but nothing happened. My first thought was that the water line had frozen to the dishwasher so it wasn't getting any water. She said she'd wait for me to come home to do anything about it. Well she never turned it off. So she comes into the kitchen 20 minutes later and there's a small waterfall pouring out of it. She's turns off the water and calls me again and is panicking and can't tell me anything about where it's coming from blah blah blah. So now when I turn on the water supply to the dishwasher even with it off it just starts to fill with water, when she had done it the bottom of the dishwasher was already full of water so it would start to immediately leak out. Water doesn't leak from the bottom until it fills up the bottom and leaks from there. I think the fill valve is broken and stuck in the open position, am I on the right track?
