Product review (5 stars): This little valve can cause the whole dishwasher to stop working
One of my tenants called complaining that there dishwasher wasn't working, when I looked at the the dishwasher to see what the problem was, I noticed that maybe my tenants hands must be broken because it look as if they never washed a dish sense they moved in (EWWWWW!!!) but that's a different story.

after trouble shooting the dishwasher, this one valve wasn't allowing the water from the main line to travel up to the top of the dishwasher to disperse across the dishes.  Changed the part and the dishwasher works like it is suppose to.  My tenant on the other hand actually using it....DOUBTFUL!!!
