Dishwasher Dispenser & Detergents
• Use only fresh automatic dishwashing detergent.
Other detergents will cause oversudsing.
• Add detergent just before starting cycle.
• Store detergent in a cool, dry location. Moist or
caked detergent will not dissolve properly.
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.
