The working principle of the drainage solenoid valve, the failure symptoms of the drainage solenoid valve

Drainage solenoid valve How it works

Solenoid valve is based on the principle that current flows through the coil to form a magnetic field. The solenoid valve of the washing machine is used when draining water. The 220V AC voltage is connected to the solenoid valve coil to form a magnetic field. The electromagnet attracts and automatically opens the rubber valve, and the water in the washing machine flows out along the pipe. After the power is cut off, the solenoid valve coil loses current, the magnetic field disappears, the electromagnet loosens, the rubber valve automatically closes, and the water in the washing machine cannot flow out.

Drainage solenoid valve failure symptoms

1. It may be drainage rubber The ring ages and cracks or loses its elasticity, resulting in poor sealing performance and water leakage.

2. Something fell into the drain valve, causing of.

3. Because the drainage rope is too short, resulting in The drainage rubber ring cannot be placed in place and cannot make close contact with the surroundings of the drainage outlet.

4. It may be caused by the solenoid valve not working properly. of.

5. The drainage rubber valve may be damaged or deformed, etc. Cause water leakage etc.

6. It may be that the drainage rubber valve is too elastic. It is too strong or has too little elasticity, and it is not tight enough with the drain outlet, causing water leakage.

Suggested solution Method:

1. Just replace the drainage rubber ring.

2. Remove the upper cover, and then remove it Washing machine impeller, then remove the inner drum cover, and finally remove the inner drum. If you don’t understand it well, it’s best to ask after-sales service to help you fix it.

3. Properly adjust the elasticity and drainage of the drain valve The length of the pull strap can be adjusted and the drain pipe can be reinstalled. It is recommended to have it installed by professionals.

4. Operate the dehydration program to see if the solenoid valve If there is movement, or use a multimeter to measure whether there is electricity in the two wires of the solenoid valve. If it does not work, the solenoid valve is broken. If there is no electricity in the two wires, it means the board is broken. Replace with a new one < strong>Solenoid valve will do.

5. Just replace it with a new one that matches the size Just use the drain valve.

6. Adjust the elasticity of the drainage rubber valve or replace it A suitable drain valve will do.
