Product review (5 stars): Pretty easy. Pulling the washer out of cabinet is hardest part.
It works great.  The dishwasher is as quiet as new (which was really the "only" problem, but damn it was loud!). The YouTube video detailed a replacement operation in my exact model, and it probably saved me at least a couple of missteps. In fairness to my skills, I "rebuilt" the machine in my last house 25 years ago... those things were a *lot* tougher because the parts were discrete.

Note: The first day when I started it, I selected extra pressure and rinse options, and it gave me an error code and wouldn't run. "Straight up" starts worked fine, so I rolled with that.  Several days later, I tried those options again and everything was fine - and has been now for a couple of months.
