Try to rub the film or residue off with a small amount of vinegar gently. If the film does not come off, it may be etching or a silica film on the glassware. Sometimes, there is a water/chemical reaction with certain types of glassware.
Laws passed in 2010 limiting the amount of phosphates in household dishwasher detergents. Major manufacturers have reformulated their dishwasher detergents for the entire United States.
This Eco-friendly change in detergents may cause a white film on your dishes, glassware, plastic items, utensils, and even the dishwasher tub.
NOTE: Antiques, feather-edged crystals, and similar types of china and glassware might be too delicate for automatic dishwashing. Wash by hand.
Is your water hard, or is there a high mineral content in the water?
Use a liquid rinse aid to help remove spotting and/ or filming. Keep the rinse aid dispenser filled.
Is the home water pressure high enough for proper dishwasher filling?
Home water pressure should be 20-120 psi. To determine if you have adequate water pressure:
Fully open the faucet nearest the dishwasher.
Place a 1-quart container under the faucet.
If the container takes longer than 9 seconds to fill, the water pressure is low. Contact a licensed qualified plumber for water pressure questions.
What type of detergent should I use?
High-quality pre-measured tablets and packs are recommended for improved performance.
Quality tablets and packs have been proven better than powder, liquid, or gel detergents at reducing filming on dishes. Using tablets and packs over time will start to reduce or eliminate white film. They are suitable for all water hardness and soil levels. Also, by using rinse aid, you can minimize the repeat buildup of the white film (not all packs and tablets contain rinse aid). Always place pre-measured detergents in the main compartment and close the lid.
The Pre-Wash indicator on the dispenser lid is for customers who use powder or gel detergent and wish to add an amount of detergent to the Pre-Wash cycle. The volume of detergent added here is approximately eight cubic centimeters if filled full and level. Any detergent added here would be immediately added to the wash when the cycle starts versus detergent inside the dispenser, which is added during the main wash cycle.
NOTE: Follow the instructions on the package when using other dishwasher detergent types.
Use automatic dishwasher detergent only. Add detergent just before starting a cycle.
Fresh automatic dishwasher detergent results in better cleaning.
Store the detergent in a tightly closed container and place it in a cool, dry place.
Extremely hard water mineral deposits (15 grains per U.S. gallon or more) can cause damage to your dishwasher and make it difficult to achieve good results. A water softener is recommended to avoid damage and achieve good results.
