Product review (4 stars): Easy replacement part, flawed design
This was an extremely easy fix and took me maybe 15-20 minutes (and I am NOT a DIYer).  I spent around $900 for a Kenmore 13963 dishwasher that had this adjuster.  This model has been a pretty good dishwasher except for this part, which is the Achilles' heel.  It has broken twice within a 3-4 year period.  The first time it happened, everything was covered under warranty.  The engineer who designed this piece of crap should be ashamed (or maybe he/she can blame the executive who wouldn't approve a more costly, robust design).  As far as I can tell, this is a 3rd party OEM part and the price at Amazon is much lower than anywhere else - so, be glad that you are not being ripped off by Sears.  Installation was easy, just a matter of unsnapping and re-snapping a few tabs.  if you need a visual see this video on YouTube:  [...].  1 star for the design, 4 stars for the fact that someone was able to produce an OEM-quality part at a low price.
