ABSTRACT:
A control circuit for dispensing detergent and a wetting agent in a dishwasher is provided in which a single triac can be utilized to selectively energize either the detergent dispenser operator or the wetting agent dispenser operator by connecting the two operators, each in series with an oppositely oriented diode, in parallel, and such connection in series with the triac, and then biasing the triac into low impedance at the beginning of either positive or negative half line cycle depending on the operator selected to be energized. If an operator is of low resistance, it is connected in series with the heater which then acts as a current limiter, and if the operator is of high impedance, it is connected in parallel with the heater.
