Product review (1 stars): Avoid the DW80H9930US, not worth the hassle especiallly at this absurd price.
(my opinion) Manufacturing defect: Second level shelf rails installed too far forward or bad batch of rails.

(my opinion) Design defect: The machine does not know the door is not fully closed.

Bottom line: weak testing at design level and manufacturing level for quality control. Cleans dishes okay, does not get angled dishes.  Does not dry well.  Always must use DRY+ mode which makes it hotter but doesn't completely dry the dishes.  Must open door to let air dry after otherwise you will get a musky mildew smell on your dishes.  Does not vent heat to try to dry dishes, hence smell.
