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.

*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.
