Replaced the dispenser with a new dispenser from AppliancePartsPros.com. I watched the available video and then began on my dishwasher. The model wasn't exactly the same as that shown in the video, but it was close enough for me to do the whole thing following along.
The hardest part of the whole replacement process was pulling the dishwasher out to get access and then putting it back into place. The actual disassembly of the door and removal/reinstallation of the dispenser was almost exactly the way it was shown in the video; that part of the repair took 20 minutes.
This was the fourth or fifth appliance repair I've done relying on the videos from AppliancePartsPros.com. I've done work on washers and dryers in addition to this dishwasher. You won't find better instructional videos.
