Product review (5 stars): Perfect replacement; perfect way to save $200.
Perfect replacement part.  My dishwasher would continue to fill after  load was done due to the old part leaving the fill valve open just a bit.  This solved the problem.  Yes, you can replace this part without taking the dishwasher out.  Remove bottom panel and on my Kenmore it is on the left.  Hardest part was removing/installing the water line as my washer has a hard cooper line.  But, with patience, out it came.  This must be done first and last.  Everything else is a piece of cake.  Unplug electrical connectors, remove one hose from a clamp then reverse the process.  One small screw holds this piece in place.  Estimated repair cost between $200 and $250, I called two places.  This was completed for less than $25.  I'm not the most handy, but I got it done.  So can you.
