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
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
oul 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. Wait 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...
I. Insert pump guard legs (on inside 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.
Check Water
Temperature
Water must be hot
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.
