The present invention provides a drum type washing machine capable of adequately distributing the laundry articles along the inner circumferential wall of the drum at the start-up of the dehydrating operation with high probability, thereby reducing the start-up time of the dehydration. In an embodiment of the present invention, the drum is controlled to rotate at a constant speed 50 r.p.m. to agitate the laundry articles (Step S 12 ), and the drum speed is almost continuously monitored. If the change in the speed does not exceed 1.5 r.p.m. for 0.5 second (Steps S 13 through S 16 ), the laundry articles are loosened and easy to distribute. Therefore, the drum speed is raised to 80 r.p.m. (Steps S 17 and S 18 ). If the eccentric load detected at this speed does not exceed a predetermined value (Steps S 19 and S 20 ), the laundry articles are adequately distributed along and pressed onto the inner circumferential wall of the drum. If a sudden change in the speed has been detected within a short period of time that is less than 36 milliseconds (Step S 22 ), the laundry articles are tangled in a mass form. Therefore, the rotating direction of the drum is reversed, and the agitating direction is restarted in the opposite direction (Step S 21 ).
