Product review (5 stars): Great, Ordered Saturday nite, arrived Monday Morning!
My old dishwasher sounded like a hammer ever since it was new.  I dread appliance repair people (numerous bad experiences) so I just put up with it.  After 2 years it died and Whirlpool wanted $270 to fix it.  A quick internet search narrowed this part as the probable culprit, so I took a chance and ordered it.  It worked great!  I would have bought locally, but appliance stores close early on Saturday, so I couldn't be sure they had it in stock.  I ordered from Amazon with 1 day shipping expecting it would go out Monday and I'd get it Tuesday.  I was very surprised and pleased it shipped on Sunday and I got it 8:30 Monday morning.  The repair was very easy, the hardest part being disconnecting the water connections and removing the dishwasher from the cabinet. It you decide to do this yourself, remember to drain it first!
