Product review (2 stars): Buy extended warranty or go to another washer
The product worked well for 10 months.  Then the amount of bacteria and scum on the tub was unreal.  We used HE detergent and we did it as instructions called for.  We don't have hard water so I chalk it up to not having the bacteria free rinse as others do.  It would create odor as well.
At year 2 the machine "main tub valve" broke and was going to be $600 to fix.  So I called Whirlpool and they said there was nothing they could do.  So  I'm going to buy a new washer and it will not be a Whirlpool ever.
