How to prevent spots and filming on glasses and flatware in my GE GDF640 Dishwasher?
- JJanet CookSep 2, 2025
If you're noticing spots and filming on your glasses and flatware after running your GE Dishwasher, it could be due to several reasons. Extremely hard water is a common cause; try using rinse agents like Finish® Jet-Dry® Rinse Aid, and consider a water softener if the problem persists. Low inlet water temperature can also contribute, so ensure it's at least 120°F (49°C). Overloading or improper loading can prevent proper cleaning, so load the dishwasher as shown in the Loading section. Other factors include old or damp powder detergent (ensure it's fresh and use a highly rated detergent), an empty rinse agent dispenser (refill it), or using too little or a low-performing detergent (use the proper amount of a highly rated detergent).
