How do I remove hard water spots and film from the interior of my dishwasher?

Load clean dishes and glasses normally without any metal utensils or silverware, and do not add detergent. Select the NORMAL WASH cycle, press START/CANCEL, and allow the dishwasher to run until it starts the second water fill (approximately 8 minutes), then open the door and pour 2 cups of white vinegar into the bottom of the dishwasher before closing the door and allowing the cycle to finish.
