Product review (5 stars): Saved me from replacing my dishwasher!!
My dishwasher was having water standing in the bottom of the tub after washing a load of dishes.  I thought my pump was going out and was thinking about having to buy a new dishwasher but a friend said maybe water is getting back into the tub at end of cycle.  I looked on the Kenmore website & looked at the part diagram and determined that this part could cause such a problem like what I was seeing so I thought it was worth spending the money to replace the part.  It did fix the problem and the old part had a lot of the stopper material missing and was pitted and cracked.
