Use only a detergent designed for an automatic
dishwasher. Never use soap, laundry detergent or
hand dishwashing detergent In your dishwasher
as it will cause severe oversudsing.
When using the Light Wash setting, place the
proper amount of detergent in the right cup of
the dispenser.
When using Regular Wash or Pots & Pans, put
the proper amount of detergent In the right cup,
slide the cover over it and put the same amount

left cup will be used for the pre-wash; the
detergent In the right cup will be released
automatically Into the main wash.)
Do not use detergent in the Rinse Hold cycle.
Amount to Use:
The amount of detergent to use depends on the
water hardness and the amount of soil on the
dishes. Generally detergent amounts should be
increased for harder water end heavier soil. Too
little detergent can result In poor cleaning while
overuse of detergent (especially in chemically
softened water) can cause permanent etching
(cloudiness) of glassware. For detergents with
low phosphate content (8.7% or less) the usage
level may have to be increased. The phosphate
content Is shown on the side of the box.
Soft (0+4 grains)
Medium (5-8 grains)
Hard (9-12 grains)
