Product review (2 stars): Not genuine.  Did not last as long as the original part.  But did work well while it did.
This is advertised as a Genuine Whirlpool part, but it was not.  It looked identical, and worked fine for 18-ish months.  However, it broke last week, and disassemble showed it had completely clogged up with scale and deposits.  Turns out there is an "unused" hole in the base plate, which lets water splash up into the motor housing, then dry and evaporate, leaving calcium deposits.  Mine had filled it so much it had jammed the rotor and seized the motor.
