Using the Dispensers

For best washing results, review the information below. It is important to use detergents and

rinse agents properly.

only.

Other detergents are too mild and

much too sudsy.

l Add detergent just before starting cycle.

detergent

results in better cleaning.

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.

How much detergent to use

l 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.

l 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%).

l Find out your water’s hardness by asking

your local water department, water soft-

ener company, or county extension agent.
