Product review (5 stars): Authentic whirlpool part
Not much to say here - this was a direct OEM replacement for our dishwasher chopper blade.

NB the 'teeth' on the back of our original chopper had worn down and were not touching the 'teeth' on the motor so we replaced this chopper first.  However, after replacement still food was still not being chopped.  After investigation, we found that the 'teeth' on the motor had also worn down and so we also had to replace the motor assembly since the 10 year old motor had been replaced with a new model and the 'teeth' assembly was not availabe as a separate part for the old motor any longer.  If you're having cleaning issues make sure there's no blockage caused by the chopper blade not chopping which in turn may be due to worn 'teeth' on the blade and the motor.
