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 waterto 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
is pumped out and replaced with 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

erful spray from rotating arms.

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.
Check Water
Temperature
2. Hold a candy or meat thermometer in the stream of hot water
to measure the temperature.
3. Ifthe temperature is too low, have a qualified person raise

. Load dishes so they don’t touch one another.
NOTE: Keep sink dmin plugs inserted during
dishwasher opemtion to prevent noise trans-
fer through drains.

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 dish-
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, Phos-
phorus softens water and
helps prevent water
spots on dishes.
If water is hard and
phosphorus content is
low (6.0% 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
in a cool dry place.
How much detergent to use
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 detergent in the covered section only for
cycles with one wash.
l Push the cover down
until it is latched.
\ ,\!L
Detergent in the open
section falls into the dish-
washer when the door is
closed. The covered sec-
tion opens automatically
when the main wash
starts.
NOTE: It is normal for cover to open partially
when dispensing detergentThe coverwill open
fully when the door is opened.
COVER COVER LATCH I

LIGHT WASH Cycle sections for.. .
POTS&PANS Cycle
NORMAL WASH Cycle
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 1or both sections to top line
if water hardness is 8 or more grains
per gallon, or 136 or more parts per
million.
l MEDIUM - Fill 1or both sections to mid-
dle line if water hardness is 5 to 7 grains
per gallon, or 85 toll9 parts per million.
. SOFT - Fill 1or both sections to bottom
line if water hardness is 0 to4 grains per
gallon, or 0 to 68 parts per million.
Rinse aid dispenser
A rinse aid helps keep water from forming droplets and drying
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. An
“E” will be visible inside dispenser when it is empty Make sure
dishwasher door is fully open when refilling. Do not fill past the
smallest opening in the lower part of the dispenser. If you overfill,
excess rinse aid can come out. This will not harm the dishwasher.
Keep the dispenser fill cap tightly closed. 3

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).
2.
4.
5.
6.
7.
Use the LIGHT WASH Cycle for normally
soiled loads. It uses less hot water and energy
than other wash cycles.
I
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.
