Product review (5 stars): Replace it from underneath WITHOUT moving the dishwasher!
I used this part to replace the leaking connector (pinhole) on my General Electric dishwasher model gsd5940D00SS.  There are a few excellent instruction videos on the interwebs, detailing the repair procedure.  You should definitely make use of these videos.  However, they all say that you have to take the dishwasher out of the cabinet and turn it upside down.  While that is certainly the correct way to do it, I was able to replace this part working from underneath, without moving the dishwasher.  First, do turn off the electrical power to the dishwasher before you start working!!  Next, I unscrewed the spray arm inside the dishwasher.  Then I used a turkey baster to remove the leftover water from the machine.  Now working underneath: I did not have to detach any of the water hoses.  I only detached the motor mount in the front, which is made from thick wire.  This allowed enough downward movement of the assembly to get the old connector out.  The connector is flexible, making it possible to nudge the old part out and the new one in.
