Using the Dispensers
For best washing results, review the information below. It is important to use detergents and
rinse agents properly.
Using the detergent dispenser
• Use automatic dishwashing detergent
only. Other detergents are too mild and
much too sudsy.
• Add detergent just before starting cycle.
• Store tightly closed detergent in a cool, dry
place, Fresh automatic dishwasher
detergent results in better cleaning.
Filling the detergent dispenser
The detergent dispenser has one section
with a cover and one without. Push cover
down firmly until it latches. Detergent in the
open section falls into the dishwasher when
closing the door. The covered section opens
automatically for the main wash.
NOTE: It is normal for the cover to open
partially when dispensing detergent.

How much detergent to use
• The amount of detergent to use depends
on the hardness of your water and the type
of detergent. If you use too little, dishes
won't be clean. If you use too much in soft
water, glassware will etch.
• Different brands of dishwasher detergent
have different amounts of phosphorus for
softening water. If you have hard water and
use low phosphorous content detergent
(6.0% or less), you may need to use more
detergent or use a detergent with a higher
phosphorous content (8.7%).
• Find out your water's hardness by asking
your local water department, water soft-
ener company, or county extension agent.
