Product review (5 stars): Perfect replacement
My Sears dishwasher began to make some terrible grinding noise after about 8 years.  From the sound, I figured it was the motor (or rather the motor bearings).  Since all the other parts of the dishwasher worked fine, I thought I'd see if I could just replace the motor myself.

After identifying the part number from the parts listing that came with the dishwasher (you can also find it through an internet search), I searched Amazon and found this motor for sale (and at a better price than available at the Sears parts web site).  It arrived quickly (Prime).  I turned off the power to the dishwasher (at the circuit breaker), turned off the hot water flow at the handle beneath the sink, disconnected the water tube leading into the dishwasher and the drain tube leading out from the dishwasher, then removed the screws holding my dishwasher in place and slid the whole dishwasher out.  Using a "star" screwdriver, I was able to remove the old motor and put this one in its place.  The electrical connection was just a snap in type, so I didn't have to do any fancy wiring.  Reassembly was just doing everything in reverse.

Motor works perfectly.  The dishwasher works better than ever, and it's so nice to have a quiet home again when the dishes are being washed.  I am quite pleased.  HOWEVER, do not attempt this repair unless you are a pretty good fix-things-up kind of guy.  The motor is very heavy, the screws are not your typical slot or phillips type, and connecting and disconnecting water pipes can result in a disaster if you make mistakes.  Also, if you fail to properly cut the electrical flow to machine before you begin the job, you could end up electrocuted.  Only experienced handymen capable of lifting relatively heavy weights should consider this job.  If you qualify (and ONLY if you qualify), and if you dishwasher is otherwise in good shape, you can save yourself some money by replacing a defective motor with this one.
