PURPOSE: A control method for cool/hot water valves of a fully automated washing machine is provided to precisely control temperature of water by controlling a single control variable. CONSTITUTION: A control method for cool/hot water valves of a fully automated washing machine includes the steps of supplying cool water to a washing tub(S11), blocking the cool water supply when the cool water in the washing tub reaches a predetermined water level(S12), supplying hot water to the washing tub(S13), blocking the hot water supply when the temperature of the supplied water in the washing tub reaches a predetermined temperature(S14), supplying hot and cool water to the washing tub under the proportional and derivative control(S15), and blocking the hot and cool water supply if the water level reaches a target point(S16).
