What happens in each option
SELECT
Energy Saver Dry option
If the Energy Saver Dry option is selected,
air in the dishwasher is not heated during
the “dry” part of the cycle. Using this option
helps save energy, but dishes take longer to
dry (overnight) and some water spotting may
result. Some items (such as plastics) may
need towel drying. For best drying results,
use a liquid rinse agent.
Low-Energy Washing option
(on some models)
When the Low-Energy Washing option is
selected, water heating is reduced during
the main wash and final rinse. This will
reduce the amount of electricity needed to
run the dishwasher. However, dishes may
not wash as well. See page 13.

Using the detergent dispenser
What type of detergent to use
l Use automatic dishwasher detergent only.
Other detergents are too mild and much too
sudsy to work in the dishwasher.
l Follow manufacturer’s directions when using
liquid automatic dishwasher detergent or
concentrated powder detergent.
l Do :lot add detergent until you are ready
to wash.
l Store detergent tightly closed in a cool, dry
place. Fresh automatic dishwasher deter-
gent is necessary for best washing results.
NOTE: Different brands of dishwasher detergent
have different amounts of phosphorus for

softening water. If water is hard and phosphorus
content is low (6.0% or less), you may need to:
See phosphorus content on package labels
l Use more detergent.
OR
l Use a brand with a higher phosphorus content
(8.7%).
10

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. See “Cycle selection chart” on
paw 8.
l Put detergent only in the covered section for
cycles with one wash. See “Cycle selection
chart” on page 8.
Cover latch
l Push the cover down until it is latched.
Detergent in the open section falls into the
dishwasher when the door is closed. The
covered section opens automatically when the
main wash starts.
Use covered section
alone for cycles

Use both sections
for cycles with
two washes
How much detergent to use
The amount of detergent to use depends on
the hardness of your water. If too little is
used, dishes won’t be clean. However, if too
much is used in soft water, glassware will
begin to etch.
l HARD-Fill one or both sections to slightly
below the top of the section (3 table-
spoons) if water hardness is 8 or more
grains per gallon, or 135 or more parts per
million. Leave enough space in the cov-
ered section to allow cover to close.
l MEDIUM-Fill one or both sections to the
top of the second step (2 tablespoons) if
water hardness is 5 to 7 grains per gallon,
or 85 to 119 parts per million.
l SOFT-Fill one or both sections to the top
of the first step (1 tablespoon) if water
hardness is 0 to 4 grains per gallon, or
0 to 68 parts per million.
Find out your water’s hardness by asking
your local water department, water softener
company or county extension agent.
Using the rinse agent dispenser
Rinse agent dispenser
Keep the rinse agent dispenser filled with a
liquid rinse agent. A rinse agent greatly
improves the drying of dishes by helping
water flow off them during the last rinse. A
rinse agent also keeps water from forming
droplets and drying as spots.
Release of a small amount of rinse agent
into the rinse water is automatic in the final
rinse of each cycle. For best drying results,
check the dispenser periodically to see if it
needs refilling.
11

To check dispenser
Remove dispenser cap. If dispenser is
empty, an “E” will be clearly visible inside
the dispenser.
“E” shows

mPty
To fill dispenser
You do not have to wait until the dispenser
is empty to refill it, but do not overfill it. The
dispenser will hoM 6 ounces (175 mL) of
rinse agent. Under normal conditions, this
will last about 3 months.
1. Make sure the dishwasher door is fully
open.
2. Remove the Fill Indicator cap.
3. Add rinse agent to the dispenser. Do not
fill past the smallest opening in the lower
part of the dispenser.
lf you overfill, excess rinse agent can
come out. This will not harm the dish-
washer, but coukf cause over-sudsing.
4. Clean up any spilled rinse agent with a
damp cloth.
5. Replace the Fill Indicator cap and keep it
tightly closed.
NOTE: Your dishwasher is designed to use
a liquid rinse agent. You do not need to use
a solid or bar-type rinse agent.
Keep rinse agent

Quiet operating tips
To avoid thumping and clattering noises
during operation:
l Make sure lightweight bad items are
secured in the racks.
l Make sure pot lids and handles, pizza
pans, cookie sheets, etc. do not touch
interior walls or interfere with the spray
arm’s rotation or cover the spray tower.
l Load dishes so they do not touch one
another.
NOTE: Keep sink drain plugs inserted during
dishwasher operation to prevent noise
transfer through drains.
12

Water temperature tips
Hot water dissolves and activates the
dishwashing detergent. Hot water also
dissolves grease on dishes and helps dry
glasses spot-free.
For best dishwashing results, water must
be at least 120°F (49°C) as it enters the
dishwasher. The dishwasher will automati-
cally heat the water to help washing
performance.
To check water temperature
1. Run hot water at the faucet closest to
your dishwasher. Let the water run for at
least one minute.
2. Measure the water temperature with a
candy or meat thermometer. Put the
thermometer in the running stream
of water.
3. If the water temperature at the faucet is
below 120°F (49”C), have a qualified
person raise the water heater’s thermo-
stat setting.
Energy saving tips
You can help save energy if you:
l Wash full loads. Running a half-filled
dishwasher uses the same amount of
electricity and hot water as a fully loaded
machine.
l lf your model has the Light Wash cycle,
use it whenever possible. The cycle uses
less hot water and energy than the Normal
Wash cycle.
l Use the Energy Saver Dry option when
you don’t need a rapid drying cycle. Allow
longer drying times (overnight). Use a rinse
agent to improve drying.
l Load correctly for best washing results.
Incorrect loading may cause poor washing
and the need to rewash all or part of
the load.
l Do not pre-rinse normally soiled dishes.
Select the correct cycle for the load and
use the recommended amount of deter-
gent for good washing results without
hand-rinsing.
l Use your dishwasher during off-peak
hours. Local utilities recommend this to
avoid heavy usage of energy at certain
times of day.
l Use the Low-Energy Washing option, if
available. The water heating in the main
wash and final rinse will be reduced.
NOTE: Loads may not wash as well if the
water temperature is too low.
13

Special tips on dishwasher use

see if it is dishwasher-safe.

Page Page
Preparing to load the dishwasher ...15 Loading the bottom rack ..................16
Loading the top rack ........................15 Loading the silvetware basket ........17
This section tells you how to properly load your dishwasher for the best washing and rinsing
results.
Preparing to load the dishwasher
l Scrape leftover food, bones, toothpicks
and other hard items from dishes.
l To save water and energy, do not rinse
dishes before putting them into the
dishwasher.
l Foods like eggs, rice, pasta, and cooked
cereals may be hard to remove if they are
left to dry over a period of time.
Run a Rinse & Hold cycle (if available) to
keep dishes moist if you do not plan to
wash them soon.
l Load dishes so soiled surfaces face the
rotating spray arms.
l Load dishes so they are not stacked or
overlapping. It is important for the water
spray to reach all soiled surfaces for best
washing. For best drying, water must be
able to drain from all surfaces.
Loading the top rack
The top rack is designed for cups, glasses
and smaller items. Some models have a
third level wash to improve washability. Do
nol cover the third level wash when loading
the top rack.
Cup and glass load
l Place so open ends face down for cleaning
and draining.
l Load glasses in top rack only. The bottom
rack is not designed for glasses. Damage
may occur to glasses in bottom rack.
l Place items in the rows between prongs.
Placing them over the prongs can lead to
breakage.
l Be sure lightweight items are held firmly
in place.
l China, crystal and other delicate items
must not touch each other during dish-
washer operation. Damage may occur.
Do not cover third level wash
(on SOIIW models)
Cup and glass load
15

Mixed load
l Load plastic items in the top rack only.
Only plastic items marked “dishwasher-
safe” are recommended.
l Load plastic items so the force of the spray
does not move them during the cycle.
l Plastic items may melt in the bottom rack.
Utensil load
l Small bowls, pans and other utensils can
be placed in the top rack.
Extra-capacity fold-down shelves
(on some models)
Extra shelves on the right and left side of the
top rack can be folded down over short items
(cups, juice glasses, cereal bowls, etc.) to
hold extra items.
Do not cover third level wash
(on some models)
I
Loading the bottom rack
Items with cooked-on or dried-on food
should be loaded in the bottom rack, with
soiled surfaces facing inward to the spray.
Mixed load
l Make sure pot handles and other items do
not stop rotation of the lower spray arm.
Spray arm must move freely.
l Load items so they do not block or cover
the spray tower.
l Securely place heavily soiled cookware
face down in rack.
Dish load
l Place plates, soup bowls, etc., between
prongs and facing inward to the spray.
l Do not place items directly over spray
tower.
16

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.
Utensil load
Loading the silverware basket
Personal Injury Hazard
Load sharp items (knives, forks,
skewers, etc.), with the point down.
Failure to do so could cause personal
injury.
l Load the silverware basket while in the
bottom rack or take the basket out for
loading on a counter or table.
NOTE: The loaded basket must be placed
in the center front of the bottom rack for
proper washing. (Style 1 basket fiis over
the spray tower.)
Some of the load may not be completely
washed if the loaded silverware basket is
placed in a different location.
l The basket can also be removed for easy
unloading. Always unload or remove the
basket before unloading the racks to avoid
spilling water droplets on the silverware.
l Load forks and spoons so they don’t nest
together. Spray cannot reach nested items.
l M’ucitems in each section of the basket
with some pointing up and some down.
l Small items (baby bottle caps, jar lids, etc.)
can be put in any section.

Caring For Your Dishwasher
Your new dishwasher is designed to give you many years of dependable service. There are a
few things you can do to maintain your dishwasher properly. This section tells you how to
clean and care for your dishwasher. Refer to “Solution chart” on pages 19-21 for special
cleaning problems.
Personal Injury Hazard
Before cleaning interior or fitter screen,
wait at least 20 minutes after a cycle
for the heating element to cool down.
Failure to do so could result in burn
injuries.
Cleaning the interior
Hard water minerals may cause a white film
to build up on the inside surfaces, especially
just beneath the door area. To clean interior:
l Apply powdered dishwasher detergent to a
damp sponge to make a paste.
OR
l Use liquid automatic dishwasher detergent
and clean with damp sponge.
Wear rubber gloves. Do not use any type of
cleanser other than dishwasher detergent
because it may cause foaming or sudsing.
Cleaning the filter screen
The fitter system requires periiic cleaning
as needed. To clean screen:
1. Unload and slide the bottom rack forward.
(Remove bottom rack if necessary to
reach filter screen.)
2. Remove collected particles from the
screen with your fingers or paper towel.
3. Return the bottom rack to original position.

mended procedure on page 13.
Use recommended dishwasher deter-
gents only.
Follow recommendations on page 10 for

generally require extra detergent.
Detergent should be fresh. Store in a
cool, dry place, preferably in an airtight
container. Discard lumpy detergent.
Home water pressure should be 20 to
120 psi for proper dishwasher fill. A
booster pump on the water supply may
be necessary if pressure is too low.
Dishes must have proper water drain-
age. Do not overload. Follow instruc-
tions for loading dishwasher on pages
15-l 7. Use a liquid rinse agent to speed
draining.
Some plastics, due to material, may
need to be towel dried.
It may not be possible to prevent
problem, except by hand-washing. To
retard this process, use a minimum
amount of detergent but not less than
one tablespoon per load. Use a liquid
rinse agent and underload the dish-
washer to allow thorough rinsing. Silica
film and etching are permanent and can
not be removed. Use the Energy Saver
Dry option.
Aluminum items should be loaded so
that they will not rub against dishes
during washing. Throw-away aluminum
items should not be washed in the
dishwasher because they may break
down and cause marking. Aluminum
markings can be removed by using a
mild abrasive cleanser.
