See as the figured circuit, the controller composed of the water level detector, trigger controller and step-down rectifier circuit, etc.
The bias circuit composed of water detecting poles of a, b, c, W1, R1,R2 and R3 is the level detector.When the level is under b, Vp-b≈R3×VDD/(Rw1+R1+R2+R3)<1/3VDD, 555 is offset, SCR is triggered and conducting, the motor runs and draws water.When the level is above a, Vp-a≈R3×VDD/(Rw1十R3)>2/3VDD, 555 is reset, 3-pin is in a low LEV. SCR is blocked and the motor stops running . (View)
