The control circuit includes the main control (6), that on the start signal drives the motor for washing for a preset time, a sensing circuit (30) comprising an amplifier A5 and a photo-coupler (3) for sensing the number of revolution of the pulley p linked to the motor, a water supply valve drive section (20) controlled by the main control counter (7), and a pressure sensing section (50) that is arranged to correct or adjust initial errors and off-set voltage and apply its output via an annalog/digital converter (15) to the main control MIC.
