Product review (5 stars): Works Flawlessly
Although some reviews indicate you can access valve from the lower front access cover, its much easier to pull entire dishwasher out from the cabinetry to have unobstructed access and vusual inspection for leaks, etc.  Only difficulty was the 3/8-inch copper elbow fitting at the connection to the original valve.  I found it easier to buy a new fitting rather than a continued struggle with the original fitting that seemed to be permanently locked in place.
