Product review (5 stars): Quick and easy fix even for a do-it-yourselfer
It was the lowest price and works great.  Unfortunately I had already pulled out the whole dishwasher from under the counter, but it's easy to access from the front so pulling the whole washer out is unnecessary.  All you have to do is cut off the water supply, remove the front lower plate, the 1 mounting screw, unplug 2 wires, 2 hoses, and then reverse the process to install the new one.  Do-it-yourself and you'll save a lot of money.
