The solenoid valve of the washing machine is used during drainage. The 220V AC voltage is connected with the solenoid valve coil to form a magnetic field, an electromagnet suction, and automatically opens the rubber valve. The water in the washing machine flows along the pipeline.After power off, the electromagnetic valve coil lost the current, the magnetic field disappeared, the electromagnet was loose, the rubber valve was automatically closed, and the water in the washing machine could not flow out.
How to repair the solenoid valve of the washing machine
Cant enter the water: One is that the circuit is not connected. During the inspection, there is no voltage without voltage at a multimeter or test -electrical pen to check the electromagnetic valve wiring end.Find out the exact failure point, take the right medicine, and connect the line.Second, if the electromagnetic valve wiring has a current flowing, but it cannot be water, it may be a failure of the solenoid valve coil. The general method is to replace a solenoid valve with the same specifications.Another reason is that the solenoid valve itself is not damaged, but the water level switch of the water inlet solenoid valve is controlled to fail, and the coil of the water inlet solenoid valve is always electric.Check the cause of the fault and rule out the failure of the water level switch.It will make the water normal.Before practicing it, you must check whether the washing machine is a problem with the solenoid valve. It is determined that the problem of the solenoid valve can be done.If you need to replace the solenoid valve, go to the hardware shop to buy a new one, change it for two minutes, and the washing machine can be used normally.
Principle of washing machine solenoid valve
The principle of direct -motion solenoid valve: When powering, the electromagnetic force is generated by the electromagnetic coil to lift the closing piece from the valve seat, and the valve is turned on; when the power is disconnected, the electromagnetic force disappears, the spring is pressed on the valve seat, and the valve is closed.Features: It can work normally during vacuum, negative pressure, and zero pressure, but the diameter generally does not exceed 25mm.When the coil (1) is powered on, the motor iron core (3) suction, the first guide valve port (5) is in the opening state, so that the main valve plug (7) to lower the pressure, the main valve plug (7) is opened due to the pressure difference, the mediumControl.Principle of distributed direct -mobring solenoid valve: It is a combination of a direct movement and a pioneer. When there is no pressure difference between the entrance and the exit, the electromagnetic force directly lifts up the pilot valve and the main valve in order.Open the valve.When the entrance and exit reaches the starting voltage difference, after the power is powered, the electromagnetic pioneering valve, the pressure of the lower cavity of the main valve rises, and the upper cavity pressure decreases, so as to use the pressure difference to push the main valve upward.Power or medium pressure push the closure part and move down to make the valve close.Features: It can also move when zero -pressure or vacuum and high voltage, but the power is large, and it must be installed horizontally.The electromagnetic valve structure is simple, consisting of coils, fixed iron cores, moving iron cores, and valve bodies.
