Diagnosis and replacement of the water inlet valve on the washing machine

For the washing machine to function properly, it is necessary that the inlet valve is installed and working well. It often fails, especially if you hard water. Replacing the water supply valve on a Samsung washing machine can help return the equipment to a normal operating mode.

Part functions

The purpose of the inlet valve is to supply water to the washing machine's tank, as well as to the container for powder and detergent. In addition, it should close access to the water supply when it is not needed. Most of the time, the intake system is in the closed state, holding back the water pressure, and at the right moment, on command from the control unit, the system opens to supply washing liquid.

Without this system, water will constantly get inside the machine, and it will not be able to work correctly.

Types of intake systems and how they work

Depending on the model of the washing machine, different types of valves can be installed. They differ number of sections. Each section is a separate water supply path. The most commonly used intake valve with a single circuit. In such washers there is no difference in the water supply - it is fed simultaneously to the drum and other systems. Two and three-section models are used in more functional units.

In general, all models of electrically operated intake systems work in the same way. Regardless of the number of working circuits, it is used for opening and closing electromagnetic coil. When voltage is applied to it, the plug opens and water passes through the hole. When the power is turned off, the plug closes under the action of the spring.

The intake valve for the Samsung washing machine works on the same principle as in any other model: when the control signal is given, the plug opens and the pressurized fluid enters the system.

Much less commonly used mechanical systems water supply.They were used in old washing machines that did not have an electronic control unit. Such valves had only 1 circuit, which was opened by means of a mechanical actuator, and access was closed using a damper. It is much simpler - except for the spring, there are no control elements in it. They rarely fail.

We check the performance

To understand whether there is a problem with the intake system in the washing machine, you need to check it. This can be done independently, without calling to the house of the master.

1. To check it is necessary to remove the valve, connect it to water supply hose. If it does not hold pressure, then it is a signal of the need for replacement. If the valve holds the water well, then we continue to check.
2. Alternately connect the power to each coil. At the same time, the valve should open and water should flow into the system. Immediately after turning off the power, the water supply should stop. If this does not happen, then it is necessary to check the valve coil. It's enough to take a tester.
3. After checking the plastic inserts dispenser - when contaminated, they reduce the amount of water supplied.If the dispenser falls, then when washing in the machine will be poured more water than is necessary for the desired mode.

After verification, we summarize whether the flap works, or it is faulty.

Repair the intake valve is impractical, it must be replaced with a new one.

DIY Replacement

To replace the valve, shut off the water, disconnect the inlet supply hose from the washing machine and proceed to disassembling a washing machine. The flap is located at the top. back wall. For convenience, it is worth moving the washing machine so that you have easy access to all the walls. On the floor, you can lay out cloths or foil, so as not to flood the neighbors.

We replace the intake valve in the following order:

• remove the top cover;
• disconnect the wires from the control unit;
• unscrew the water supply valve (as a rule, it is mounted on several screws to the rear wall);
• change a spare part for a new one (it is better to purchase a part in advance, having selected it exactly according to your model);
• we collect everything in the reverse order;
• we connect the car and we carry out trial washing.

By changing the inlet valve of the washing machine according to the algorithm described above, you can again operate the unit in the same mode.

The main thing is to choose a similar original part, otherwise the washing machine may not work correctly.

Repair Tips

DIY repair washing machine Samsung or any other should be carried out only with full confidence in their abilities. To change one part for another is not difficult, but if something is wrong to assemble or connect, you can ruin the working elements. It is very dangerous to get water inside the washing machine - you can spoil the electronics or the motor itself.

Select the necessary tool in advance and take a picture of the collected elements - this will help to correctly assemble the washing machine after repair. During assembly it is necessary to firmly tighten all internal and external hoses: when a weak connection can pass water that can damage the internal elements, causing corrosion. Worth paying attention to water aroundThis may be evidence of the flow of compounds.
