The drain valve is one of the necessary parts to ensure the washing machine is working properly. If you want to learn about the structure of the washing machine drain valve to facilitate troubleshooting when encountering, please refer to the article below right away!
What is a washing machine drain valve?
Structure of the washing machine drain valve
The washing machine drain valve is an indispensable part in the washing machine with the main task of which is to drain the washing water in the process that the machine cleans clothes. The structure of the washing machine drain valve is also quite simple, mainly including:
- Small electromagnetic motor with rotor (which is a kind of permanent magnet).
- Centrifugal pump.
Working principle of washing machine drain valve
The washing machine drain valve is controlled by a solenoid valve using a voltage of 220V , and is divided into DC (symbol of direct current) and AC (symbol of alternating current).
In other words, the solenoid valve works thanks to the alternating voltage passing through the coil to form an electromagnetic field, which helps the drain valve to automatically open so that the water inside the washing tub is discharged through the pipe.
Conversely, when there is no AC voltage flowing through the coil, there will be no electromagnetic field, at this time the drain valve will automatically close and water cannot be discharged from the drum.
Signs that the washing machine drain valve is broken
Although the structure is simple, the drain valve is an indispensable part of the washing machine. So, if you see some of the following signs, it is very likely that your washing machine drain valve is damaged:
- The washing machine has a non-stop draining problem.
- The washing machine cannot close the drain valve.
- Wastewater from the drain valve is weak due to scale build-up inside the water pipe or valve.
- Drain valve wire is loose.
- Tractor drain valve is damaged.
The cause of some errors on the washing machine related to the drain valve
The drain is blocked due to a problem with the drain valve
The vibration of the moving iron core inside the solenoid valve is too great or the suction power is reduced , which can all be the cause of the clogged drain line.
Not only that, the appearance of dirt inside the water pipe or valve also becomes the cause of the washing machine not draining water.
Because the drain pipe is too high
The design of the drain pipe is too high or the drain pipe is easily bent, which will prevent the washing machine from draining as well as affect the operation of the solenoid valve.
Damaged discharge pump, pull-out
Loose adjustment rod nut on the exhaust valve or the tractor’s towing cable can also be the cause of the discharge valve.
And yet, if the spring inside the drain valve loses its elasticity or has been used for too long , or the gap between the rubber valve and the drain lever is larger, it will also cause the drain valve to work poorly, causing the discharge of tap water. poor washing as well as clogged.
Broken solenoid valve control board
Damaged parts of the circuit board inside the solenoid valve or small components inside the drain valve are the cause of poor performance of the drain valve, affecting the draining process of the washing machine when operating.
How to repair the washing machine drain valve?
With the causes of damage to the washing machine drain valve, you will have a corresponding remedy. Such as:
How to fix the problem of washing machine not keeping water?
If the washing machine cannot hold water for the washing cycle taking place in the drum, you need to check and clean the residue inside the drain valve along with the water inlet and drain pipes.
How to repair the solenoid valve control board
If you have determined that the cause of the solenoid valve is damaged, the internal circuit board is broken, then proceed to disassemble this part of the washing machine to check by using a multimeter to measure the voltage between the 2 plugs of the tractor. (exhaust valve).
If the measured voltage is 220V , the exhaust valve puller has a problem, and if the voltage is not 220V , the board inside the solenoid valve is damaged. What is damaged, you just need to repair or replace it!
How to open the washing machine drain valve
Opening the washing machine drain valve will help you check the condition inside this part. Therefore, you can use pliers to remove the decoupling pin that connects the solenoid valve hardware and the regulator frame.
Then you loosen the screws to the chassis to proceed to remove the overflow pipe and short drain pipe. Next, you hold the valve body and rotate it from right to left several times to separate from the outlet.
So you can disassemble the washing machine drain valve to check and clean it!
Note when repairing the drain valve and how to maintain the washing machine
In the process of repairing the drain valve, you need to pay attention to a few issues as follows:
- Avoid doing repairs yourself at home if you do not have enough expertise in refrigeration, as this can make the damaged part worse.
- Refer to the manufacturer’s instructions on the product such as the detailed structure of the parts on the machine to determine the correct drain valve, convenient for you to operate.
- Clean the washing machine periodically, every 6 – 9 months to promptly detect problems related to the washing machine.
- When repairing the drain valve, you can take pictures of the original condition and then remove the drain valve for inspection and repair. This will help you compare the drain valve before and after troubleshooting.
- The washing machine should be placed in a cool place, away from moisture or direct sunlight because it may damage the parts and components on the washing machine.
Hopefully these shares have helped you understand more about what the washing machine drain valve is as well as the structure of the washing machine drain valve when there is a need to determine to fix the problem of water discharge when the washing machine is in operation. okay then!
