Product review (1 stars): A bad machine from the start.  Avoid.
I'm writing as I'm about to junk this thing after two years.  As far as washing goes, it is a poor performer.  Any dish that egg has touched must be washed by hand.  We have tried many detergents, using pot scrubber mode, pre soaking, pre washing, you name it.  Nothing works.  Same goes for starchy foods, especially potatoes and rice.  If you cook either of these things and then put the dish in the dishwasher, the entire load will be covered in a white film.  Pot scrubber mode does not scrub the pots well enough to avoid hand washing afterwards, so there is no point in using it. Dishes always come out wet even when using jet dry.  Every 6 months or so it breaks a glass.
The racks themselves are not strong enough to hold up to normal use.  The first year was okay, but since then every 3 months somethin has broken-- we have gone through 3 tine clips and a wheel.  And these flimsy plastic parts are not cheap to replace.  Apparently this is an issue across many whirlpool products, so please do your research before buying a Whirlpool or KitchenAid dishwasher.
After 2 years the machine has started leaking water when filling the tub.  Considering how much the repair will cost, the constantly breaking dish racks and the poor washing performance it's just not worth fixing.
