Dishwasher Dispenser & Detergents
Filling 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.
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.
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.

*Note: For very hard water, detergent alone may not be enough. A water softener is recommended to improve
water quality and dishwashing performance. Try adding more detergent at the beginning of the main wash portion
of the cycle. As a rule, use 1 teaspoon for each grain above 12. Unlatch the door, open slowly and add detergent
to the bottom of the tub. Close the door to latch and the dishwasher will continue through the cycle.
