For Best Results
Your dishwasher cleans by spraying a mixture 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 removes 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
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 particles are flushed
away as water is pumped out. Larger particles
are trapped in the pump guard.
To remove the pump guard for cleaning...
1. 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 center to release the latch.
4. Lift out and rinse clean.
To replace the pump guard...
1. Inset-t pump guard legs [on inslde 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
Removable Pump Guard
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 meatthermometer 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 drarning.
l Load glasses in top rack only. Bottom
rack is not designed for glasses. Damage

to breakage.

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 washlng results.
Store detergent tightly in
a cool, dry place.
1 The detergent dispenser
I
The detergent dispenser has one section with
a cover and one without.
l Put detergent in both sections.
l Push the cover down
until it is latched.
The cover opens auto-
matically when the main
wash starts. Detergent in
the open section falls
into the dishwasher
when the door is closed.
COVER COVER LATCH
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 watefs 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 grainS Of
hardness.
l SOFT - Fill both sections to bottom
lineifwaterisOto4grainsof
hardness.

Energy saving tips
You can help save energy lf 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.

2. Air dry dishes when you don’t need a rapid
drying cycle. Allow longer drying times
[overnight].
Load correctly for best washing results. In-
correct loading may cause poor washing
and the need to rewash all or part of the
load.
4. Don’t pre-rinse normally soiled dishes.
Using the WASH Cycle with the recom-
mended amount of detergent and proper
loading will provide good washing results
without hand rinsing.
5. Use your dlshwasher during off-peak hours,
Local utilities recommend this to avoid
heavy usage of energy at certain times of
day.
