For Best Results
Your dishwasher cleans by spraying a mixture of hot, clean water and detergent
against sorled surfaces of dishes, When a cycle ISstarted, the drshwasher fills with Water
to about the level of the heating element. This water IS pumped through the rotating
spray arms, drained through the filtersystem which removes food and soil, and pumped
back through the rotating spray arms. Soiled water is pumped out and replaced wrth
clean water during a cycle- the number of times depends on the cycle being used
The self-cleaning filtering system and
removable pump guard help eliminate pre-
rinsing by removing food particles from the
water.
Load dishes so soiled surfaces face pow-
erful spray from rotating arms.
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 partrcles are flushed
away as water is pumped out. Larger particles
are trapped in the pump guard.
To remove the pump guard for cleaning...
1. Wait at least 20 minutes atter 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 center to release the latch.
4. Lift out and rinse clean.
voble Pump Guard
To replace the pump guard...
1 Insert pump guard legs [on inside wall] into
matching openings in filter screen.
2. Press down on outside wall until latch snaps
into place.
3. Replace bottom rack with rack bumpers in
front.
Water must be hot For best cleaning and drying resutts, 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.
Top rack loading
The top rack is designed for cups, glasses
and smaller items.
l Place so open ends face down for clean-
ing and draining.
l load glasses in top rack only. Bottom
rack is not designed for glasses. Damage
may occur.
.
.
l Place items in the rows between prongs.
Placing them over the prongs can lead
to breakage.
Be sure lightweight items are held firmly
in place.
China, crystal and other delicate items
must not touch another item during dish-
washer operation. Damage may occur.
l Load plastic items only in the top rack.
Only plastic items marked “dishwasher
safe” are recommended.
l Plastic items can be melted in the bottom
rack.
l Small bowls, pans and other utensils can
be placed in the top rack.
l Items with cooked-on or dried-on foods should be loaded in the bottom rack with
soiled surfaces facing the spray.

Bottom rack loading
l Make sure pot handles and other items
do not stop rotation of either the upper or
lower spray arm. Spray arms must move
freely.
l Securely place heavily soiled cookware
face down in rack.
\ UTENSIL LOAD
l Load cookie sheets, cake pans and other
large items at sides and back. Loading
such items in front may keep water spray
from reaching detergent dispenser.
NOTE:
l Do not load glasses, cups or plastic items
in the bottom rack.
l When lower rack is removed, replace
with bumpers in front.
6
l Place plates, soup bowls, etc. be-
tween prongs and facing the spray.
SilverwaFe basket loading
Load the silverware basket while it’s in or
out of the bottom rack. The loaded basket
should be in the right front corner of the
bottom rack.
YES
Load forks and spoons so they don’t
nest together. Spray can’t reach nested
items.
Mix items in each section of the basket
with some pointing up and some down.
Small items - baby bottle caps, jar lids,
etc.- can be put in any section.
Make sure sharp items (knives, forks.
skewers, etc.) are put in point down. Make
sure long items do not stop the upper
spray arm from turning.

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,
Ditferent 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).
Da 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 wiih one wash.

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 water’s 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
Fill 1 or both sections to
middle line if Water is 5 to 7 grains of
l SOFT - Fill one or both sections to
bottom line if water is 0 to 4 grains of
hardness.

Energy saving tips
You can help save energy If you:
1.
3.
Wash full loads. Running a half-filled dish-
washer uses the same amount of electricity
and hot water as a fully loaded machine.
Alr 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.

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