Disclosed is a washing machine (1) provided with: a dewatering tub (2), a bottom (2c) of which is provided with a stirrer (4); three baffles (8), which serve as a water delivery pipe and are disposed at equal intervals in a circumferential direction on an inner circumferential surface (2a1) of the dewatering tub (2), and are open near the bottom (2c) and are provided with circulating water ports (80) formed in the upper end thereof; a water receiving ring unit (5), which is fixed at the upper end of the dewatering tub (2) and formed by overlapping three annular water guide grooves (5a, 5b, 5c) that are connected to the upper ends of the baffles (8) respectively in a radial direction; and a nozzle unit (30), which is capable of separately injecting adjustment water into each of the water guide grooves (5a, 5b, 5c), wherein the levels of bottom surfaces (5ta, 5tb, 5tc) of the three water guide grooves (5a, 5b, 5c) are lowered in order from an outer peripheral side to an inner peripheral side. The washing machine (1) allows adjustment water to smoothly move from the water guide grooves (5a, 5b, 5c) to the baffles (8), and appropriately carries out control for eliminating an unbalanced state of the dewatering tub (2).
