Product review (5 stars): Fairly easy to install, once you have access to the right side of the dishwasher
Just installed this on my Bosch SHE3ARF2UC/21 dishwasher. Seems to be running better now, time will tell. Installation was pretty easy. It is located on the right side (when facing) of the dishwasher at the bottom. I had direct access to the side, so did not have to pull the dishwasher out. Also, an appliance website suggests laying the dishwasher on its back. That would surely help, but I was able to pop the control unit out and then pull the connectors without doing that. Took plenty of pictures of the wiring harness. Connectors were a wee bit difficult to pull, but a pair of needle nose pliers and small screwdriver helped.
