Abstract
A dishwashing machine includes at least one additive distributor for dispensing additive into a wash tub, a first electrically controlled actuator for operating the distributor, a water softener for softening water supplied to the wash tub, a regeneration circuit for regenerating the water softener, a second electrically controlled actuator for operating the regenerating circuit, and a programmer for controlling the operation of the first and second actuators. The first and second actuators are electrically connected in parallel to each other. A single switch is controlled by the programmer for connecting the parallelly connected first and second actuators to a power source for at least one first time period and at least one second time period longer than the first time period. The first and second actuators have response times respectively shorter and longer than the first time period, and the response time of the second actuator is less than the second time period.
