Product review (5 stars): Easy, inexpensive and arrived quick.
Arrived on the 4th day.  Ahead of scheduled time.  Packaged securely.

Our dishwasher is 30 years old.  The new ones, s/a Kitchenaid, are impossible to repair, and are lucky to last 5 years.  Mine took 30 minutes to replace the pump/motor.  Just like new.

Most difficult part is unhooking the power, water and drain.  Pulled it out, tipped it on it's back, and was amazed at the ease of access and ease of replacement.

Instructions are wordy and cover several models.  However, it is very easy to do, without them.  I used a phillips screwdriver, pliers, and some electrical tape.  I  also used a nutdriver (5/16" ??) to loosen the bands on the big drains.

The old unit leaked and was noisy.  Amazingly, the new pump/motor is very quiet.

Maybe this will last another 30 years before I replace it again.
