POWER CLEAW ”Washing System
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, through
the POWER CLEAN Module which removes food particles, and 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 POWER CLEAN Module removes food parti-
cles from the water, stores them, then washes
them down the drain.
Load dishes so soiled surfaces face power-
ful spray from rotating arms.
Step-saving preparation for washing
It is not necessary to rinse dishes before
putting them into the dishwasher. Just remove
large pieces, bones, and other hard items. The
POWER CLEAN Module will remove food parti-
cles from the water. It contains a chopping de-
vice which will reduce the size of food items.
If hard items such as fruit seeds, nuts and egg
shells enter the POWER CLEAN Module, you
might hear chopping, grinding, crunching or
buzzing sounds. Those sounds are normal when
hard items enter the module. DO NOT LET
METALLIC ITEMS (I.E. POT HANDLE SCREWS)
GET INTO THE POWER CLEAN MODULE. THIS
COULD RESULT IN DAMAGE TO THE POWER
CLEAN MODULE.

140°F - 60°C). Two ways to have a reliable hot
water supply...
1. Maintain 140°F water supply at central water
heater. To check water temperature, turn on
hot water faucet nearest the dishwasher. Let
water run until it is as hot as possible, then
check with a candy or meat thermometer. If
Quiet operating tips
To avoid thumping and clattering noises during
operation:
l Make sure lightweight load items are secured
in the rack.
l Make sure pot lids and handles, pizza pans,
cookie sheets, etc. do not touch interior walls
i
the temperature is too low, have a qualified
person raise the water heater thermostat
setting.
2. Use HI-TEMP WASH Option. If water heating is
needed, a thermostat will delay the cycle un-
til temperature reaches 145” (63°C). If water is
hot enough, the cycle will proceed with no
delay. This lets you turn down your water
heater, if you choose, without cutting back on

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 un-
til you are ready to wash.
When using Delay Wash,
make sure the detergent
dispensers are clean
and dry before adding
1 The detergent dispenser
The detergent dispenser has one section with
a cover and one without.
l For cycles with one wash, put detergent in one
section only.
-Use the open section if the cycle begins with
a wash.
- Use the covered section if the cycle begins
with a rinse.
l For cycles with two washes, put detergent in
both sections.
W l Push the cover down until it is latched.
I
Detergent in the open section falls into the dish-
washer when the door is closed. The covered
section opens automatically when the main
wash starts.

The amount of detergent to use
depends on the hardness of your

Find out your water’s hardness by

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,
but could cause over-sudsing. Keep the dispenser fill cap tightly
closed. 7

You can help save energy if You:
1. Wash full loads. Running a half-filled dish-
washer uses the same amount of electricity 2. Use the LOW ENERGY WASH Cycle whenever

than other wash cycles.
3. Air dry dishes when you don’t need a rapid 4. Load correctly for best washing results. In-
drying cycle. Allow longer drying times
(overnight). correct loading may cause poor washing
and the need to rewash all or part of the
load.
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.
6. Use Your dishwasher during off-peak hours
Local utrlities recommend this to avoid
heavy usage of energy at certain times of
day.
7. 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.
