I found manufacturers stating to use 2 cups of white vinegar in order to remove the white residue from the inside of the dishwasher. I threw in 2 cups of white vinegar and set the dishwasher to Normal, Hot wash, I turned off Heated dry, and I didn't use any soap. It removed some of the white residue. I repeated the wash cycle with white vinegar 2 more times and most of the white residue is gone now.
