Note: The amount of
detergent needed can
vary due to differences
in water hardness. The
harder the water, the
more detergent you
may need. Adjust the
amount of detergent
you need by small
amounts until you find
the correct amount.
Please contact your
local water utility
company if you have
questions about the
hardness of your water.

Detergent Dispenser

The detergent dispenser must be refilled before the start of each wash
cycle following the instructions provided in the "Wash Cycle" table on
the previous page. This dishwasher uses less detergent and rinse aid
than conventional dishwashers. Generally, only slightly more than one
tablespoon of detergent is needed for a normal load of dishes. Add
the detergent just before starting the dishwasher; otherwise, it could
get damp and will not dissolve properly.

Water Hardness

The amount of detergent to use depends on whether your water is
hard or soft. With hard water, you need extra detergent to alleviate
the deposits that are left by the excessive minerals. Less detergent is
needed for soft water.
To identify whether your water is hard or soft, contact your water
department. A water softener is recommended for water that contains
twelve or more grains. Without it, lime can build up in the water valve,
which could stick while open and cause flooding. Too much detergent
with soft water can cause a permanent cloudiness of glassware,
called etching.
For heavily soiled loads, use the Heavy wash cycle, fill one or both of
the interior cups, depending on the hardness of your water, and also
fill the open cup on the dispenser lid.
Use the information in the table below as a guideline to determine the
amount of automatic dishwasher detergent to place in the dispenser:
Number of Grains
Less than 4
4 to 8
8 to 12
Greater than 12
To open the wash cover:
Press the button and the cover will flip back revealing the detergent
dispensing cups. See diagram to the left.

Removing Hard Water Spots

To remove hard water spots, try the following:
Run dishes through a normal wash program.
Remove all metal dishware, such as cutlery, pans, etc. from the
dishwasher.
Do not add detergent.
Pour two cups of vinegar into a bowl and set the bowl face-up
on the lower rack of the dishwasher.
Run the dishes through a normal wash program.
If this doesn't work, try the same process with ¼ cup of citric acid
crystals instead of vinegar.
