Product review (5 stars): Cheap and worked
I must have searched around 20 different websites for this thing once I found the right part number.  A lot of those websites had cheaper prices, but after getting free shipping on this order, and not wanting to wait 4-6 weeks or some other B.S., I chose amazon.

Directions I found online and helpful hints from posters here helped me get this on really easily, and now it works great.  I don't have to buy a new dishwasher or pay a technician to come out here and fix it.

Took me about an hour and a half of fiddling, figuring, and playing and it was done.  Probably could have been done in 15 minutes honestly, but it felt good to be handy so I didn't mind.
