ABSTRACT:
A control system is provided for a fabric washing machine including a controller for controlling the machine through a predetermined cycle of operations and having a first state at which the cycle may be initiated and a second state at the end of the cycle. A lid actuated switch is in circuit with a power supply and the controller and is operable between first and second conductive postures by movement of the lid. First circuitry is connected to the first conductive posture of the switch for energizing the controller in the first state to control the machine through the cycle and terminate operation at the second controller state at the end of the cycle. Second circuitry is connected to the second conductive posture of the switch and is operable with the controller in the second state for initiating modification of the controller to the first state to condition the controller for initiation of a new cycle of operations. Operability of the switch to the second conductive posture is a prerequisite to initiating a new cycle of operations.
