Its 12 pins are +5V power supply, and 24 pins are ground; Pins 11 and 12 are oscillating terminals, and external 500kHz crystal oscillators are connected; , pin switch SW1, SW2, SW3, SW 4 as program, cycle, water flow selection buttons respectively; and 22 pin water flow selectable display diodes v20 and v21; and Socket Cycle Selection Display Diode V18 and Socket V15-V16 LEDs as program selection indications; and feet to monitor the working status of the pressure switch and the safety switch respectively; 13 pins monitor the power supply voltage to protect the voltage of the chip The pins output control signals, and drive the thyristor VQ1 and VQ4 through V310-V313 to realize the control of the motor, drain valve and water injection valve.

The V306 converts the 50Hz AC negative half-cycle into a square wave and sends 17 pins to the microprocessor as a synchronization signal, so that the thyristor is triggered by zero crossing. The V301 is a simple series-regulated power supply that provides +5V.

There are six connectors on the electric annoyance board, which are connected to the motor, pressure switch, safety switch, water injection valve, drain valve and power switch.

In addition, the front and back sides of the entire computer board are sealed with 8 mm thick transparent glue to prevent waterproof and corrosion. The sealant was removed during the repair, and the glass glue was resealed after the repair inspection was correct to ensure safety.
