To provide an economical washing machine capable of reusing drain water.
Water stored in an outer tub 5 in a washing process and a rinsing process is guided to a water storage tank 17 when the water is drained from the outer tub 5. The water stored in the water storage tank 17 is electrolyzed by the current application to an anode 19 and a cathode 20, and organic substances are precipitated in the bottom of the water storage tank 17. The precipitated organic substances are floated and separated with micro-bubbles by feeding micro-bubbles into the water in the water storage tank 17 from the micro-bubble generating device 40. The water (treated water) in the water storage tank 17 after the organic substances are floated/separated is fed into the outer tub 5 through a treated water suction pipe 32 and a water supply pipe 9 to be reused.
