DISHWASHER DISPENSER & DETERGENTS CAUTION The use of industrial grade detergent can damage the heating coil and other parts of the dishwasher leading to damage to the unit and surrounding property. Use only household grade automatic dishwasher detergents. Cover Main Wash Cup Pre-Wash Cup Cover Latch Filing the Detergent Dispenser The detergent dispenser has one covered and one uncovered cup. Detergent in the uncovered cup falls into the dishwasher when the door is closed. The covered cup opens automatically to release detergent. • Use only fresh automatic dishwashing detergent. Other detergents may cause oversudsing. • When using automatic dishwashing detergent tabs, place one tab in main wash cup and close. • Add detergent just before starting cycle. • Store detergent in a cool, dry location. Moist or caked detergent may not dissolve properly. If the cover is closed on the Main Wash Cup open by pressing the Cover Latch. How much Detergent to use The amount of detergent to use depends on the water hardness. Water hardness is measured in grains per gallon. Using too little detergent can result in poor cleaning and hard water filming or spotting. Using too much detergent in soft water can cause etching to some glassware which is surface damage that appears like a film but cannot be wiped off. Your local water company, water softener company or county extension agent can tell you the water hardness in your area. Cycle Detergent Usage Chart Soft Water Medium Hard Water (0-3 grains) (4-8 grains) Hard Water (9-12 grains) Very Hard Water (Over 12 grains) Heavy Wash or Normal Wash 2 teaspoons (each cup1/4 full) 5 teaspoons (each cup- fill to line above "Regular") 8 teaspoons (each cupcompletely full) Each CupCompletely Full (water softener recommended) As a rule, use 1 teaspoon for each grain above 12. For very hard water, detergent alone may not be enough and then a water softener is recommended to improve water quality and dishwashing performance. 9
