What should I do if my dishes have spots and film on them?

Spotting can be caused by several factors: extremely hard water, old or damp powder detergent, low inlet water temperature, low phosphate level in detergent, overloading, improper loading, empty rinse agent dispenser, or too little detergent. To remove stubborn spots, run the POTSCRUBBER cycle without detergent for 18-22 minutes, then pour 2 cups of white vinegar into the bottom and complete the cycle.
