Product review (5 stars): Whirlpool 675806 Impeller Kit - Great Product - Great Price
This dishwasher impeller repair kit arrived on time and with all parts as advertised.  I used it to repair my
Kenmore 665.17795791 model.  I installed these parts and they worked well however my problem was not fixed.
It turns out that my dishwasher still has some water remaining in the bottom after it runs.  The reason turned out
to be due to a small piece of metal lodged on the check valve for the drain hose.  This check valve is located
adjacent to the motor under the dishwasher.  I am providing this info in the hopes that it helps others who
experience a dishwasher which only partially drains.
