Product review (5 stars): It "did the trick"!!!
My dishwasher lights would come on but NOTHING would happen. I went on-line and found several very informative videos on how to replace the latch assembly (since no instructions come with the part).

Since a defective or broken latch assembly is most often the problem when lights come on but the dishwasher won't start, I decided it was worth trying to replace it myself (for less than $30) rather than paying an appliance repairman to visit or just buying a new dishwasher. I'm glad I did it myself. It was very easy to do and seems to have solved my problem.

Amazon's price was less than anywhere else for the exact part I needed----thank you Amazon!
