Product review (5 stars): Direct Replacement for WhirlPool - works great.
Perfect fit for my Whirlpool Quiet 2 dishwasher, indistinguishable from the old part I removed.  The dishwasher stopped filling with water.  I did some online searching and saw that this was the likely culprit.  Replacement was fairly easy. Unplug power, turn off water, remove bottom cover to dishwasher. The valve is located on the bottom right.  Saved myself a lot of time and money by doing it myself.  Shipping was quick too.
