In this type of washing machine during operation, strong electricity and weak electricity are separated. The electromechanical-type program controller fully automatic washing machine connects and disconnects circuits by connecting and breaking the current paths through various touch points inside the program controller, thereby controlling the operation of electrical components. Regardless of which type of electrical control system, their controlled objects are the same, namely the water inlet solenoid valve, drainage solenoid valve, and motor; their detection mechanisms are also the same, namely the lid (safety) switch and water level (pressure) switch.
