Do-It-Yourself Story

This was not an obvious source of a leak. The Tower Heater Assembly Nut developed a crack over time due to heat exposure. So the leak was gradual slowly getting worse over time. It was a hairline crack that ran down one of the edges of the nut making it hard to see. In talking to a pro he said it isn't a common problem. It is all the way in the back of the bottom of the dishwasher so it is not something you can see without pulling the dishwasher out and running it. The repair itself is easy. I replaced the washers that go on the inside under the heating element just to be sure. But the old ones hadn't worn out at all. This stopped the leak.
