Thanks for the question.
Does the motor sound like its going slower than normal.
Thew number 22 in the breakdown is the impeller kit the kit includes the motor seals.
That would be the way to go, you were lucky to get 10 yrs out of that unit,
for another $ 200.00 you can buy a new d/w though.
I think I will go that way since the unit came with the house when we moved in 6 years ago. I am saving more than half the price of a new one from what I have seen at Lowes and Home Depot. I wanted to do business with the local store but the prices seemed out of line.
Is the impeller kit a fairly straight forward replacement? Or do I need any extras that I mentioned in my last communication.
