A method for maintaining a set temperature of wash water of clothes washer comprises the steps of supplying first cold water into a wash tub, measuring supply time of the first cold water until filling a first target level of the first cold water, measuring temperature of the cold water contained in the wash tub, supplying hot water and second cold water in the wash tub containing the first cold water, measuring supply time of the hot water and the second cold water until filling a second target level of the hot water and the second cold water, measuring temperature of mixed water being comprised of the hot water and the first and second cold water contained in the wash tub, and comparing temperature of the hot water which is calculated on the following four values-supply time of the first cold water, temperature of the first cold water, supply time of the hot water and the second cold water, and temperature of the mixed water with predetermined temperature, and controlling a valve for the cold water and a valve for the hot water.
