Dishes Do Not Dry Completely

Silica Film or Etching (Silica Film is a White Irides- cent Deposit; Etching is a Cloudy Film)

Black or Gray Marks on Dishes

Dishes do not drain PropeW

Plastics

A water chemical reaction with certain types of glassware. Usually caused by some combination of sofl or softened water, alkaline washing solutions, insufficient rinsing, over-loading the dishwasher, and heat of drying.

Aluminum items

Dishes must have proper water drain- age. Do not overload. Follow instruc- tions for loading dishwasher on pages 15-l 7. Use a liquid rinse agent to speed draining.

Some plastics, due to material, may need to be towel dried.

It may not be possible to prevent problem, except by hand-washing. To retard this process, use a minimum amount of detergent but not less than one tablespoon per load. Use a liquid rinse agent and underload the dish- washer to allow thorough rinsing. Silica film and etching are permanent and can not be removed. Use the Energy Saver Dry option.

Aluminum items should be loaded so that they will not rub against dishes during washing. Throw-away aluminum items should not be washed in the dishwasher because they may break down and cause marking. Aluminum markings can be removed by using a mild abrasive cleanser.
