Product review (5 stars): thanks to correct diagnosis
This was the key piece that made my dishwasher light up and work again.  However, I owe most of the success to my boyfriend who was able to take the front panel apart and diagnose the problem accurately.  When the part came, it was a simple installation for him.. BTW we think the original part eventually became damaged over time by roaches that got in there. I was also spraying around in there with roach killer.... a warning to others.
