For Best Results
Your dishwasher cleans by spraying a mix-
ture of hot, clean water and detergent against
soiled surfaces of dishes. When a cycle is
started, the dishwasher fills with water to a bout
the level of the heating element. This water is
pumped through the rotating spray arms,
drained through the filter system which re-
moves food and soil, and pumped back
through the rotating spray arms. Soiled water
is pumped out and replaced with clean water
during a cycle-the number of times depends
on the cycle being used.
If-cleaning filtering system and
removable pump guard help eliminate pre-
rinsing by removing food particles from the
The filtering system
It is not necessary to rinse dishes before
putting them into the dishwasher. Just remove
large pieces and quantities of food and bones.
The filtering system helps keep food particles
out of the wash water. Small particles are flushed
away as water is pumped out. Larger particles
are trapped in the pump guard.
To remove the pump guard for cleaning...
I. Walt at least 20 minutes after a cycle for
the heating element to cool down.
2. Unload and remove the bottom rack.
3. Press the outside wall of the pump guard at
the centerto release the latch.

Load dishes so soiled surfaces face pow-
erful spray from rotating arms.
Check Water
A Temperature
For best cleaning and drying results, water should be at least
140°F (60°C).
1. Turn on hot water faucet nearest the dishwasher. Let water run
until it is as hot as possible.
2. Hold a candy or meat thermometer in the stream of hot water
to measure the temperature.
3. If the temperature is too low, have a qualified person raise
the water heater thermostat setting.

Proper loading
Always load dishes so soiled surfaces are reached by spray from rotating spray arms.
Water must be able to drain off completely for best drying results. Be careful to Separate
items so spray can reach all surfaces.

Adding detergent
The kind and amount of dishwasher detergent you use is an important part of
getting your dishes clean. Read this section carefully.
Use automatic dlsh-
washer detergent only.
Other detergents are
too mild and much too
sudsy to work in the
dishwasher.
Different brands of
dishwasher detergent
have different amounts
of phosphorus. Phospho-
rus softens water and
helps prevent water
spots on dishes.
If water is hard and
phosphorus content is
low (8.7% or less], you
may need to use more
detergent or use a
brand with a higher
phosphorus content
(12% or higher).
Do not add detergent
until you are ready to
wash. Fresh, dry deter-
gent is necessary for
best washing results.
Store detergent tightly in
a cool, dry place.
The detergent dispenser
The detergent dispenser has one section with
a cover and one without.
l Put detergent in both sections for cycles with
two washes.
l Put deteraent in the covered section only for
cycles w’ih one wash.
l Push the cover down
until it is latched.
The cover opens auto-
matically when the main
wash starts. Detergent in

How much detergent to use
The amount of detergent to use
depends on the hardness of your
water. Iftoo little is used, dishes won’t
be clean. However, if too much is
used in soft water, glassware will
begin to etch.
Find out your waters hardness by
asking your local water depart-
ment, water softener company or
county extension agent.
l HARD - Fill 1 or both sections to top
line if water is 8 or more grains of
hardness.
l MEDIUM - Fill both sections to
middle line if water is 5 to 7 graifIS of
hardness.
l SOFT - Fill both sections to bottom

hardness.
Rinse aid dispenser
A rinse aid helps keep water from forming droplets and dry-
ing as spots. Keep the dispenser filled with a rinse aid such as
Jet-Dry.” A small amount is released automatically during the
final rinse of each cycle. Check the dispenser periodically to
see if it needs refilling.
Keep the dispenser fill cap tightly closed.

Energy saving tips
You can help save energy if You:
1. Wash full loads. Running a half-filled dish-
washer uses the same amount of electricity
and hot water as a fully loaded machine.
3. Air dry dishes when you don’t need a rapid
drying cycle. Allow longer drying times
(overnight).
5. Don’t pre-rinse normally soiled dishes. Se-
lect the correct cycle for the load and use
the recommended amount of detergent for
good washing results without hand rinsing.

mally soiled loads. It uses less hot water and
energy than HEAVY WASH.

load correctly for best washing results. ln-
correct loading may cause poor washing
and the need to rewash all or part of the
load.
Use your dlshwasher during off-peak hours.
Local utilities recommend this to avoid
heavy usage of energy at certain times of
day.
