Customer Questions and Answers for Actuator by Bosch

Mike, first check the speed control switch, make sure one of the buttons is pressed and locked down in place, then check the switch circuit. Since you've already tried a timer, you'll need to check the wires to the motor for damage or loose connections. The timer reverses the polarity (direction of electrical current) to the motor to make it reverse directions, if the motor runs in the spin cycle, it should also run in the agitate direction as well.
