The amount of detergent needed can
vary due to differences in water hardness.
To determine the water hardness in your
area, contact your local water utility or area
water softening company. The harder the
water, the more detergent you may need.
Refer to the chart below for the recom-
mended detergent amounts based on
water hardness. Remember, you should
adjust the amount of detergent you use
by small amounts until you find the correct
amount.

Note that 12 grains and higher is extremely
hard water and detergent alone may not
be enough. You may need to use a water
softener to maximize the performance of
your washer. Also, in areas with extremely
hard water (9+) you may need to wash at
lower temperatures to prevent hard water
deposits from forming in the tank and wash
system.
Different brands of detergent have differ-
ent amounts of phosphorous for softening
water. If you have hard water and use a
detergent with less than 8.7% phospho-
rous content, you may need to use more
detergent or use a detergent with a higher
phosphorous content.
