Brand new.  The "Heated Dry" function does NOT work in any way.  (Yes, I am placing the on-off toggle to "ON").  My dishes and the dishwasher itself are continually extremely wet after the entire cycle has completed.  I am using the rinse aid feature EXACTLY as suggested in your manual.

I must towel dry my dishes.  I must leave the dishwasher wide open, with both racks pulled completely out, to get it to air dry.  It takes at least 2 days for the washer to air dry in this manner.  Imagine the mold/calcification buildup if the washer was to sit, dripping wet, for weeks on end if I didn't leave it open to dry!
