A. Détergent Dispenser ~ Bi-Meial Operated
The Bi-Wletal trigger used to release the detergent cup locking cam is made of two different metals which are bonded
together. The expansion rates of these metals are considerably different. The trigger bends when healed and releases
the locking cam, (See Figures 46 and 47.
The Bi-Wielal trigger is a low voltage device. It is placed in series with the dishwasher healing element. Current flowing
through the healing element is directed by the timer through the trigger mechanism either during or immediately after
the fill period for the second wash. The current heals the trigger and the cam is released.
Several different circuits have been used with these devices. Always refer to the wiring diagram for the model you
are servicing In all cases, power is taken from a timer terminal to one terminal of the Bi-Metal The other Bi-Metal
terminal is connected to the red heater lead, usually at the timer. The timer switch that normally supplies the healer
power must be open while detergent cup operation lakes place.
