Dishwasher Dispenser & Detergents Filling the Detergent Dispenser The detergent dispenser has one main wash and one prewash 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 will 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 will not dissolve properly. 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. 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 a permanent film called etching. Your local water company, water softener company or county extension agent can tell you the water hardness in your area.
