ABSTRACT:
An electronic control for a laundry washing machine is timed by mains derived pulses which are counted for timing. A plurality of executive blocks are summoned in turn to regulate the various operations by time signals from the counter and by sensers denoting the conditions are right; the drum speed is derived from an error signal but the speed regulating signal mainly comprises the integral of the true error signal.
