PROBLEM TO BE SOLVED: To perform an automatic priming and prevent the overflow of priming water from a suction port by dividing the discharge port downstream side of a tap water feeding solenoid valve into two passages, allowing one of them to communicate with the water injection port of a washing tub, and allowing the other to communicate with a priming port through priming hose. SOLUTION: When a power source switch is on, and a bathwater course start button is pressed, a current is carried to a feed solenoid valve 31 for a prescribed time, for example, 15 seconds. The water leaving a discharge port is collided to the wall of a priming feed port 33, and part of the water is supplied as priming water from the priming water port of a casing cover 41 into a pump through a priming hose 34. After the lapse of 15 seconds, the current carrying to the feed solenoid valve 31 is stopped, the motor 43 of a bathwater suction pump is rotated, a suction chamber 41d is laid in a negative pressure by the rotation of a runner 42 to suck bathwater through a sucking hose 27 connected to a suction port 26a. The bathwater is supplied to a washing tub through a discharge chamber 40i and a discharge pipe 26b.
