Replaced the shaft seal on my 30 year old GE Pot scrubber 1200, which otherwise from the leak functioned flawlessly. The seal fit perfectly since it was OEM, but I didn't need the push-on nut because this particular model had a factory washer and c-clip holding the seal in place. Actual seal replacement was done in less than 15 minutes but the most time spent was on cleaning years of dust from the dishwasher exterior and the counter cavity it sat in. Plus, I decided to replace the hot water line and upgraded the hard-wired connection from 14/2 to 12/2 cable. Finally, the shipping service was outstanding. I was a bit incredulous when the site stated that I'd receive the seal in 1.7 days on standard shipping. In reality, it was more like one day.
