Product review (1 stars): Lasted 18 months, then failed spectacularly.
EDIT 12/10/2017: This thing failed in spectacular fashion about 18 months after I installed it, dumping the ENTIRE contents of the Rinse Aid liquid holder with every wash cycle. Sometimes it dumps it during the wash, other times, after the wash is done, where it runs down the inside of the door. I expected it to last more than 18 months, but that was obviously a fantasy.

Relatively easy to install (I did have to remove the front panel, and replacing it is sometimes a two person job), fit right in place, hooked up and working.

As an aside, why are all major appliances now built to last five years or less? It's pathetic. The first dishwasher I owned (bought in 1980) lasted 25 years with minor repairs. The second one started needing parts about three years in and got too expensive to fix after 5 years of very moderate use (3-5 times a week). The current one also started needing replacement parts after just 3 years, and every few months, something else malfunctions. In the last three months alone, this dispenser failed, the spring assembly that counterbalances the door snapped a cable, the "Start" pushbutton switch failed, and two days ago, the thermal fuse went, taking the unit down AGAIN.

I tend to do my own repairs on things like this, and it's turning into a full time 'hobby' now. If I had to pay to have someone come out to fix all these issues, I'd be a LOT more upset.
