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 about
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
bspumped out and replaced with clean water
during a cycie-the number of times depends
on the cycle oeing used.
Load dishes so soiled surfaces face pow-
erful spray from rotating arms.
The self-cleaning filtering system and
removable pump guard help eliminate pre-
rinsing by removing food particles from the
water.
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..
IWait at least 20 minutes after a cycle tar
the heating element to cool down.
2. Unload and remove the bottom rack.
3. Press the outside wail of the pump guard at
the center to release the latch.
4. Lift out and rinse clean.
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
Check Water
Temperature
140 FWater must be hot
For best cleaning and drying results, water should be at least
140°F {60°C).
t. 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. It the temperature is too low, have a qualified person raise the
water heater thermostat setting,

fer through dralns.

Adding detergent
The kind and amount of dishwasher detergent you use is an important part of
getling 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 conlent is
low [6.0°,'0 or less], you
may need to use more
detergent or use a brand
with a higher phosphorus
content [8.7% or higher].
Do not add detergent
until you are ready to
wash. Fresh automatic
dishwasher detergent
is necessary for best
washing results. Store
detergent tightly closed
nn a cool dry place.

Use AIR DRY only
HEAT DRY or AIR DRY?
If the HEAT DRY Option isselected, air in the
dishwasher is heated during the "dry" part of
the cycle
If the AIR DRY Option is selected, air in the
dishwasher isnot heated. Using this option helps
save energy, but dishes take longer to dry (over-
night) and some water spotting may result.
Some items (such as plastics) may need towel
drying.
For best results, use a solid rinse aid.
Changing a setting
You can change a setting anytime during
any cycle.
1. Liftup on the door latch to unlatch the door
and stop the cycle. Don't open the door until
the spray arms stop spinning.
2. Turn the Cycle Control Knob clockwise to the

stop the cycle. Don't open the door until the
spray arms stop spinning.
3. Open the door and add the dish.
4. Close the door Do not latch it. Wait 30 sec-
onds for air in the dishwasher to warm up. This
helps reduce the amount of moisture that
can come from the vent when restarting the
cycle.
5. Press door firmly to latch it. The dishwasher
will automatically start where it stopped

Energy saving tips
You can help save energy if you:
I, Wash full loads. Running a half-filled dish- 2. Use the LIGHT WASH Cycle for normally
washer uses the same amount of electricity soiled loads. It uses less hot water and energy
and hot water as a fully loaded machine, than NORMAL WASH.
3. Airdry dishes when you don't need a rapid
drying cycle. Allow longer drying times
(overnight].
4.
5.
7.
Load correctly for best washing results. In-
correct loading may cause poor washing
and the need to rewash all or part of the
load
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.
Use your dishwasher during off-peak hours.
Local utilities recommend this to avoid
heavy usage of energy at certain times of
day.
Kitchen cleanup can be done quickly and
efficiently through the use of your dishwasher.
Most appliance parts that can fit in the dish-
washer can be cleaned by it. Burned-on soil,
however, should be cleaned by hand.

Special tips on dishwasher use
Remember, use your dishwasher only for the job it was designed to do.
Some items ate not dishwasher safe or may require special care.
Read these special tips for the following items:
Aluminum: Aluminum loses its bright, shiny appearance and darkens in color due to minerals in
the water and the alkalinity of the dishwasher detergent Colored aluminum may fade.
TIPS: It washed in the dishwasher avoid placing directly in front of detergent dispenser where
it could be sprinkled with undissolved detergent, causing spotting, pitting, and discoloration.
Follow utensil manufacturers' cleaning instructions.
China: Hand-painted, metal-trJmmed_ and antique china fade due to high water temperatures
and a_kaline detergent solution in the dishwasher. NOTE: Delicate, antique items should not be
washed in the dishwasher.
TIPS: Load china carefully, Do not allow pieces to touch each other Testone piece by washing it
daily in the dishwasher for several weeks, Then compare it with the rest of the set to see if colors
have changed.
Crystal and decorative glasses: Crystal can break from sudden exposure to high water
temperature. Metal trim and colorful decoration on glass will fade in time when washed in the
dishwasher NOTE: Delicate, antique items should not be washed in the dishwasher.
TIPS: Load crystal carefully in top rack only. Be sure to load a few larger items in the bottom rack
to reduce amount of force of water spray reaching glassware from lower spray arm. Use the
shortest cycle.
Flat_¥are.* Salty and acidic foods may tarnish silver and stainless flatware if allowed to remain on
the utensils. A film may form on sterling silver and silver plate items washed in a dishwasher. This film is
caused by reaction of silver with chlorine in the detergent. Gold flatware is not dishwasher sale.
TIPS: Rinse flatware as soon as possible, especially if it is not to be washed right away. Dishwasher
detergent may remove antique finishes. Wash by hand. Tarnish and film build-up can be removed
with silver polish.
Cast iron utensils: The seasoned finish will be removed in the dishwasher. Rusting will result,
TIPS: Wash by hand. To re-season, coat with unsalted fat and heat in a slow oven torah hour or two.
Plastics** Many plastics will have "Dishwasher Safe" written on them. Some plastics are heat
sensitive and may melt or warp,
TIPS: if in doubt, try one piece. Place in upper rack only. AIR DRY option provides additional
protection.
Non-stick finish utensils: Most can be washed in the dishwasher.
TIPS: Follow manufacturers' suggestions.
Wood: Many wooden items will crack and warp or lose their finish,
TIPS: Do not wash cutting boards, wooden salad bowls or knives with wooden handles in the
dishwasher.
Pewter or pcwter-like materials: May streak, discolor, and pit.
TIPS: To keep pewter at its very best, hand wash with mild detergent
Dishwasher care & cleaning:
Exterior - Regular use of a soft damp cloth or sponge
and a mild detergent is all that is necessary, in most cases,
to Keep the outside of your dishwasher nice looking and
clean. Interior Hard water minerals may cause a
white film to build-up on the inside surfaces,
especially just beneath the door area,
Wear rubber gloves when cleaning
the dishwasher interior. Do not use
any type of cleanser other than
dishwasher detergent because
it may cause foaming or sudsing.
