Product review (1 stars): Stay Away!
Wish I could give 0 stars. Total garbage. Had it less than 5 years. Nut worked itself loose at the bottom causing the entire gear assembly to shift downward. Everything started grinding. Bearings shot, caused a water leak that rusted the motor which pretty much kills the machine.  Even when it worked it didn't clear well at all.
Customer service didn't help even with all the similar problems with this machine. Never to buy a Whirlpool product again.
