Heater

The heater mounted in the bottom of the tub in-
creases water temperature, then in the dry cycle
assist in drying the dishes. See Figure 21 The
amperage draw of the heater can vary depending on
the job it is to perform. When heating water, the
amperage draw can be 900 watts. This amperage
will drop to approximately 700 watts in the dry cycle.
The design of the heater is to be more energy
efficient. Mounted next to the heater on the under
side of the tub is a safety thermostat. This thermo-
stat will open if the temperature in the tub raises over
200°F. See Figure 22
Figure 21

Door baffles

Baffles have been installed into the bottom of the
inner door panel to direct hot air out of the dish-
washer. Foam baffle is mounted to the outside
bottom of the inner door panel to keep steam and air
from rising into the door. This foam baffle most not
be removed. See Figure 23

Dispensing System

The detergent and rinse aid dispenser consists of
two dispensers combined in one housing and are
controlled with one wax motor actuator. The first
time the control energizes the actuator the cover
over the detergent side of the dispenser opens
dispensing detergent for the main wash cycle. The
second time the actuator is energized rinse aid is
released for the final rinse cycle. The detergent side
of the dispenser consists of two cups: the smaller
cup is for detergent used in the pre-wash cycle, the
second larger cup is for the main wash section of the
cycle. The rinse aid section contains a reservoir that
will hold enough rinse aid for many applications. See
figure 24 This reservoir has an indicator that will be
clean if rinse aid needs to be added. A reed switch
has been added to the rinse aid dispenser that
informs the control when the rinse agent is low the
control then displays and LO in the display to inform
consumer of this condition. There is also an adjust-
able hub inside the dispenser, seen by removing the
cap, to control the amount of agent dispensed. This
detergent and rinse aid dispenser is replaced as a
complete assembly. The cap for the rinse aid dis-
penser is the only part available for this dispenser.

Dispenser Operation

The dispenser has two detergent cups both covered
by the same cover. In the bottom center of the
spring loaded cover is a thumb release. By pushing
up on this release, the cover will open. The larger of
the two cups, under the cover, is used for the main
wash cycle the smaller for the pre-wash. With the
detergent added the cover is closed. The cover is
slotted so the detergent from the smaller pre-wash
cup can be washed out without the cover opening.
