Abstract
A progress indicator for a washing machine comprises display means having six light-emitting elements to indicate which stage of a washing or rinsing cycle the machine is in. The display means are controlled by signals outputted from detectors of turbidity and the amount of water in the tank. Although the operation is not temporally controlled, say, but a timer, this indicator can accurately display the progress of operation.
