Product review (4 stars): Easy part to replace and a big money saver
Our dishwasher was leaking all over the kitchen and into the basement.  We thought we would need a new one, but tried replacing this part first.  It runs better and quieter than it has in years!  If your dishwasher starts to take a lot longer to wash and gets noisier, replacing this part is the likely easiest and cheapest option.  Do that before you flood the kitchen!
