What is a water level sensor in a Samsung washing machine, what kind of breakdowns are possible?

Each Samsung washing machine is equipped with a water level sensor. Its second name is pressure switch.

He assesses whether or not there is water in the tank, and then sends a signal to the controller, which decides which operation to apply next. Failure of the sensor leads to malfunctions in the washing machine.

The article will discuss where the pressure switch is located, how to check the water level sensor in the Samsung washing machine for operability and fix possible problems.

Where is the pressure switch located?

The pressostat is a small round piece. The sensor is made of plastic. It is connected to the tank using a tube, and to the controller - by wires.

How to check?

It is not difficult to check the water level sensor yourself, the main thing is to get access to the part. Sometimes it just needs to be cleaned, and sometimes repair or replacement of a component is required.

How to understand that it is working properly?

To understand that the sensor is working correctly, you need to do the following:

1. Unscrew the 2 screws on the back of the washing machine, then you can easily remove the cover.
2. Disconnect the pressure switch located on the side of the washing machine. It is attached to it with bolts. Be sure to remove the connectors with wires and the clamp securing the hose and fitting.
3. Dismantle the part.

To understand that the sensor is working, you first need to inspect it. There should be no blockages in the tube, if any, they are removed. Corrosion and contamination are removed from the lamellas.

Initial check instructions:

1. Put a hose on the fitting and blow into it. If the sensor is OK, a click should be heard.
2. There can be from 1 to 3 clicks. It depends on the model of the washing machine. If there is no sound, the part is broken.
3. If you have an ohmmeter, you can check the functionality of the contacts. When closing and opening them, you need to pay attention to the readings of the device. Normally, they should change.

The initial self-test does not take much time and does not require special skills.

When is setup required?

Adjustment is required after installing a new sensor, or if the water level in the drum does not correspond to the wash phase. There may be too much or too little liquid. The initial settings are made at the factory when the washing machine is assembled.

When is repair or replacement needed?

Understand that the water level sensor needs replacement or repair, can be on the following grounds:

• the machine continues washing or turns on the heating element, even if there is water in it;
• the tank is overfilled with water, or too little is collected;
• during rinsing, the water is periodically pumped out and enters the tank again;
• a burning smell appears and the heating element fuse is triggered;
• the machine does not start spinning;
• after spinning, things remain wet;
• some liquid remains in the tank after draining the water.

If there is one or more symptoms of a malfunction, it makes sense to check the function of the pressure switch.

If the machine has already been disassembled and the sensor is removed, then the need to replace it is indicated by the absence of a click when blowing the tube, as well as the lack of response of the multimeter when the contacts are closed and opened.

How to setup?

Before you start adjusting the sensor, you need to disconnect the washing machine from the mains. The pressure switch has 3 adjusting screws... The main screw is centered. It is most convenient to adjust it with a Phillips screwdriver.

To do this, turn it half a turn, after which the machine is assembled and put into operation. If the water level is not satisfactory, the cover is removed again and the bolt is again turned half a turn, after which the test is again carried out.

Intermediate visual control of the sensor is a prerequisite. Otherwise, the setting may end with the failure of the machine. If there is no knowledge and experience in this process, then it is better to entrust the work to a professional.

The fact is that when starting different modes, the machine can use a different amount of water, for example, with the “gentle wash” program, the tank is often filled only up to the middle.

At the factory, fine tuning is carried out by a specialist, and the position of the regulators is fixed with paint or varnish... You should not change the position yourself, so as not to disrupt the operation of the washing machine.

How to replace?

If the sensor is defective, it needs to be replaced. Repairing the part does not make sense, since it will not work to disassemble and assemble the pressure switch housing. Any attempt to open it will cause the component to malfunction.

Sequence of actions when replacing water level sensor:

1. Dismantle the old pressure switch.
2. Using the screws, install a new device in its place.
3. Connect the fitting and the hose, tighten the clamp.
4. Connect the wire connectors in the order in which they were connected earlier.
5. Replace the cover of the washing machine.

Where and for how much to buy a new part?

You can purchase a new water level control sensor at a specialized service center or store, or order it online. Sometimes the part is available from private craftsmenrepairing washing machines.

However, very often they sell used pressure switches that were removed from other devices. Such a sensor can work for several years or several days. There is no guarantee for it.

Before making a store purchase, you need to make sure that the new sensor is exactly the same type and name as the previous one. It must match the make and model of the washing machine.

This parameter directly affects the price sensor and varies from 900 to 2000 rubles.

The newer and more expensive the washing machine, the higher the price of all components will be.

When buying a sensor, you need to take a check from the seller... If it turns out to be faulty, it must be replaced at the outlet.

How much does the master's services cost?

If it was not possible to cope with the replacement of the pressure switch on your own, you need to call the master. You can find it by an ad on the Web or in a newspaper. It is possible that some of the acquaintances used the services of such a specialist and was satisfied with his work.

Reputable workshops can afford to provide a free visit of the master and diagnostics of the device, and discounts are often offered to retirees and low-income citizens.

The cost of work on replacing the pressure switch is about 1600 rubles. This procedure takes no more than an hour in time. Decent organizations give a guarantee for all work performed, which should not be less than 6 months.

Prices for the services of a master may differ, depending on the locality... However, they should not be 2-3 times more expensive. If a specialist asks for too high a price, you should not trust him.

Private craftsmen can offer more favorable terms of cooperation. However, calling such a repairman should not be left alone with him. If he asks for money for a service that he did not perform, you need to threaten to call the police.
