An operation control device for a washing machine incorporating electrical equipment such as a motor and electromagnetic valves includes a sub microcomputer for controlling the electrical equipment incorporated in the washing machine and a host microcomputer supplying control commands to the sub microcomputer to control the same. The host microcomputer determines whether or not a control sequence of the washing machine has reached a stage where the incorporated electrical equipment are to be controlled by the sub microcomputer and then, supplies a reset signal to the sub microcomputer to reset the same when a result of the determination signifies a negative.
