The washing machine is provided with an inner rotatable drum which can be expanded for the wash and rinse cycles of the machine and contracted for the spin cycle of the machine. The drum includes front and rear end walls, and a plurality of wall segments connected to the end walls so as to define the side wall of the drum. The movement of the sidewall segments is controlled by a linkage assembly and a shaft actuated with a motor. By contracting the sidewall of the rotatable drum during the high speed spin cycle, unbalanced loads are eliminated or minimized.
