Abstract

Abstract A full automatic washing machine includes an outer tub, a rotatable tub rotatably mounted in the outer tub, an agitator rotatably mounted in the rotatable tub and an electric motor for driving the rotatable tub and the agitator. The volume of clothes accommodated in the rotatable tub is detected. A control circuit controls either a stored-water rinse mode in which the clothes are rinsed with water being stored in the rotatable tub or a rinse-with-dehydration mode in which the clothes are rinsed and dehydrated with the water supplied into the rotatable tub. The stored-water rinse mode is selected when the detected volume of clothes is large. The rinse-with-dehydration mode is selected when the detected volume is small.
