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 a level
slightly above the heating element. This water is constantly pumped through the rotating
spray arm and center wash tower onto the dishes. Soiled water is pumped out and replaced
with clean water during a cycle. The number of times depends on the cycle being used.
Loud dishes so soiled surfaces face the powerful spray from rotating arm and center
wash tower.
Preparing the load for washing
It is not necessary to rinse dishes before putting them into the
dishwasher. Just remove large pieces and quantities of food
and bones. Foods that are burned onto utensils (not just cooked
on] may be difficult to remove. Some hand washing may be
necessary
Water must be hot
140 F
Cl
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 ISas hot as possible
2. Hold a candy or meat thermometer 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

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 or
intlerfere with the spray arm rotation and center wash tower extension.
l Load dishes so they don’t touch one another.
NOTE: Keep sink drain plugs inserted during dishwasher operation to prevent noise transfer
through drains.

wash tower. Water must be able to drain off completely for best 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 L’our dishes clean Read this sectlon 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 (6.04, 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

Energy saving tips
You can help save energy if you:
1. Wash full loads. Runnrng o half-filled dish-
washer uses the same amount of electrrcity
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 moderately
soiled loads. It uses less hot water and energy
than NORMAL WASH.
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 utillties recommend this to ovoid
heavy usage of energy at certain times of
dav
Kitchen cleanup can be done quickly and
efficiently through the use of yourdishwasher.
Most appliance parts that can fit in the dish-
washer can be cleaned by it. Burned-on soil,
however, should be cleaned by hand.
