wattage drops to approximately 700 watts. This
design makes the heater more energy efficient. There
are two different shaped heaters used in these
products but both function the same. Along with the
heater, there is also a safety thermostat that is
mounted under the tub on the left side. This thermo-
stat will open if the tub temperature raises over 200°
F. It will reset after the tub temperature drops below
100°F. This is to protect the dishwasher tub.

FILL SYSTEM
The fill system consists of the water fill valve and a
float safety switch. The water valve is an electrically
operated shut off valve having also a built-in flow
washer. The purpose of the flow washer is to regu-
late the quantity of water leaving the valve based on
the water pressure applied to the valve inlet. To
insure there is proper water flow into the tub, the
water pressure to the valve needs to be between 20
and 120 psi. The amount of water used is deter-
mined by the electronic control. The float safety
switch is used to stop power to the water valve if the

tub is over filled for any reason. Water from the water
valve enters the tub from the left side through an air
gap mounted to the side of the tub.

DISPENSING SYSTEM
The dispenser assembly combine two dispensers
using one common wax motor actuator. One dis-
penser is for wash detergent the other for rinse aid.
The dispensers are actuated by the electronic control
energizing the common wax motor actuator. First to
be dispensed is the detergent, this is done in the main
wash cycle. The rinse aid is released in the last rinse
cycle just before the dry cycle. The rinse aid dis-
penser can be adjusted by the consumer by removing
the filler cap and changing the setting found in the
dispenser opening. The dispenser assembly is
replaced as a complete assembly. The only indi-
vidual replacement part for this assembly is the filler
cap.
DISPENSER OPERATION
The dishwasher has two detergent cups. One is for
pre-wash detergent. This cup can be molded into the
inner door panel or a partitioned off section under the
detergent dispenser cover. The second cup is in the
dispenser covered by a spring loaded cover. This
cover can be released manually or automatically by
the control.
