Product review (4 stars): Works great. Cheaper than buying just the motor
Pros: Works great. Cheaper than buying just the motor.

Cons: Does not include the water sensor(?).

Notes:
Worked great.  Just be careful and make sure you buy the correct unit for your dishwasher.

I went through the whirlpool site and cross referenced the replacement parts.  This one superseded the part I had on my washer.  It failed to mention that the water sensor(?) had changed.  Luckily all the other parts were interchangeable and all I needed was the motor.  So I just disassembled the new unit and installed the motors and gaskets on the old plastic housing so I could reuse the water sensor.
