An object of the present invention is to perform efficient stroke control in accordance with dirt of a washing liquid. SOLUTION: A turbidity detecting means 92 provided in a drainage duct 75 for detecting the turbidity of washing liquid by infrared transmission, a pair of electrodes 94 provided on the inner periphery of the outer periphery of an outer tub 43, and Conductivity detection means 78 including a water detection circuit 98, a dirt detection circuit 99, and the like, and a control means 87 for controlling operations of the drive means 48 and the like, and sequentially controlling a series of steps of washing, rinsing and dehydration. In the washing process, the control means 87 detects the washing liquid turbidity by the turbidity detection means 92 to determine the degree of dirt, and the conductivity detection means 78 detects the washing liquid conductivity and determines the degree of dirt. It is possible to achieve efficient process control and performance improvement by determining and finally determining the degree of contamination from the clothing based on the two determination results and performing subsequent process control.
