Proper Use of Detergent:
The amount of detergent to use depends on the type of water in your living area
whether it is hard or soft and whether items are lightly or heavily soiled.
Water softness or hardness is measured in grains content per gallon (gpg). You can
find out the gpg level by calling your local Environmental Protection Agency (EPA) in
your county.
If you find that the gpg level is higher in the water, then the water will be harder in
your living area. You will need more detergent to clean. If gpg level is lower, then
the water will be softer in your living area so you will need less detergent to clean.
See the following table to understand the "water hardness type" and gpg level.
Note: If gpg level is over 12, then water is very hard. You may need water softener
to improve the water quality and the performance of your dishwashing.
Note: The quality of the detergent will make a big difference in the cleaning of
dishes. Detergent that is damp or too old will not be as effective to clean because the
active ingredients will be phased off. Detergent will not work properly.
Note: Use only "Automatic Dishwasher Detergent" for your dishwasher.
Other types of detergents that are not for dishwasher use may cause foaming. Do
not use detergents that are dried, caked or moist. These types of detergents will not
dissolve properly and will clean effectively.
Pouring Dishwasher Detergent:
Use the recommended amount of detergent for your wash loads. Measure and pour
the detergent into the large compartment for the main wash. The detergent for the
pre-wash goes into the small compartment next to the main wash compartment.
Note: For the pre-wash, you should use one-half the amount of detergent that you
use for the main wash.
We recommend that you use a Rinse Agent to help remove spots and prevent new
film build-up on your dishes, glasses, flatware, cookware and plastic.
Note: Use only a liquid form of rinse agent in the dispenser
