Disclosed is a water-supply valve of a washing machine in which the consumption of electric power can be minimized in opening and closing the valve to supply water into and block off the water supply into a washing tub of the washing machine. In the water-supply valve, an actuator rod is elevated against downward biasing force of a spring by a magnetic force of the first solenoid generated by applying an electric current thereto, and then is retained at its uppermost position by the attractive force of the permanent magnet. And, the actuator rod starts to be lowered by a magnetic force of the second solenoid generated by applying an electric current thereto, and is retained at its lowermost position by the downward biasing force of the spring.
