Product review (5 stars): Purring again
The original motor of my diswasher, which I used daily, for 8 years purred quietly like a kitten,,,then WHAM!! it was roaring and grinding LOUDLY like a lion.  My son tore it apart, assessed the problem and we ordered the Whirlpool W10239404 Pump and now my super quiet motor is again purring quietly.  You cannot even tell it is running.  The motor is purrrrfect.  And ask my son,,,I'm not easily impressed.  Be sure to  have the model number of the old motor to make your seach go easier but again Amazon had what I needed at a less painful cost than others. Got great service and fast delivery from Amazon.  I would recommend them highly.
