Do-it-yourself repair of the samsung sc8870 vacuum cleaner

In detail: do-it-yourself repair of a samsung sc8870 vacuum cleaner from a real master for the site my.housecope.com.

For any household appliances, sooner or later breakdowns are characteristic, the Samsung vacuum cleaner is no exception. To delay this moment for as long as possible, the Samsung sc 6570 vacuum cleaner needs proper care.

Although this will not give eternal performance to your unit, whether it is a Samsung vacuum cleaner or other brands, so you should prepare in advance for a vacuum cleaner breakdown, at least mentally. Often, such units require replacement of a Samsung vacuum cleaner brush, dust collector or bag.

If the equipment has broken, for example, a filter for a Samsung vacuum cleaner, the repair is fully justified. Or, for example, your vacuum cleaner is so dear to you that there is no desire to part with it, or the purchase of a new Samsung vacuum cleaner (including the Samsung robot vacuum cleaner) was not included in the family budget plans, then it is worth considering such a solution to the issue as a repair that you can conduct it yourself or contact the service center.

Some vacuum cleaners have too expensive spare parts, so sometimes it is easier to buy a new vacuum cleaner than to pay for the repair of an old one.

Modern repair centers can replace the flask, electric motor, power regulator for sc 6570 vacuum cleaners. But a dust collector or a turbo brush, a hepa filter or a hose, as well as bags - everyone can easily buy and replace these parts on their own.

Before attempting to repair a Samsung vacuum cleaner or another company, you should understand its device. So, for example, each vacuum cleaner is equipped with an air suction unit, where air is sucked in. And in front of it there is a filter designed to clean the air (vacuum cleaners with a water filter work according to a slightly different principle).

Video (click to play).

Most often, the filter for a Samsung vacuum cleaner is made by Nera. The air is cleaned when it enters the Hepa filter, and then it goes to the engine, where it performs a cooling function.

The engine must be cooled to avoid overheating. If the cooling is carried out sufficiently, then the vacuum cleaner, or rather the motor of the Samsung vacuum cleaner, can work continuously for 120 minutes. The way a vacuum cleaner motor works is also significantly influenced by the filter for a Samsung vacuum cleaner.

It is preferable to use the hepa filter for Samsung vacuum cleaners (it is also installed on a cordless vacuum cleaner), especially for the Samsung sc 6570 model. It is recommended to keep the hepa filter clean at all times.

In general, vacuum cleaners experience mechanical or electrical breakdowns:

Electrical breakdowns can be caused by a problem with the sc 6570's outlet or plug. If removed correctly, the problem may be in the cord, possibly cracking or kinking. If such problems are found, they need to be repaired.
In addition, electrical breakdowns are possible due to malfunctioning brushes or the motor itself burned out. You can make repairs or completely replace the electric motor of the vacuum cleaners.
For vacuum cleaners (sc 6570, etc.), mechanical breakdowns are also possible when a hose, motor or brush for a Samsung vacuum cleaner breaks down (a common problem with washing vacuum cleaners for laminate flooring). For example, if the sc 6570 vacuum cleaners hear a hacking hum during operation, the electric motor is working very loudly, and the air is not sucked in, then the hose is most likely clogged. To troubleshoot, it is recommended to remove the hose and clean it carefully. To do this, it is recommended to pass a heavy metal ball through the hose to locate the blockage.Then insert the squeegee handle into the hose and gently stir up the blockage. If the hose is accidentally damaged during cleaning, you will need to buy a new hose.
Sometimes poor absorption occurs when the power regulator is set to minimum parameters. If the settings are standard and the absorption is low, the power regulator itself may have broken. Replacing the power regulator is easy. It is difficult for a person who is not particularly versed in electrical engineering to repair the power regulator on his own. That is why it is easier to buy a new power regulator and insert it into the sc 6570 vacuum cleaner.
Often, poor suction is caused by a clogged dust container or waste bag. To fix this problem, you need to remove the dust container or bag. The dust container is thoroughly washed and replaced, and the bag should simply be thrown away and replaced with a new one.
Low suction can occur when the filters are clogged. You should carefully read the instructions that each vacuum cleaner has. It indicates how many filters and where they are installed. Experts recommend putting your vacuum cleaner on hepa filters. Generally hepa produces universal spare parts for all vacuum cleaners. So, having studied the instructions, remove the filter that protects the electric motor from dust. Some filter models, for example, hepa, can simply be rinsed with warm water, but it must be dried before installing. If, according to the instructions, the filter cannot be washed, then buy a new hepa brand and install it yourself.
Sometimes the vacuum cleaner does not turn on at all, for example, when the electric motor burns out. The repairs and maintenance that the vacuum cleaner motor sometimes requires should only be carried out by specialists. The price of such a spare part as an engine is sometimes prohibitively high, but in some models it is economically justified to replace the motor.
Sometimes the vacuum cleaner sucks well, the power regulator is normal, the dust collector or bag is not clogged, the electric motor is running, and the vacuum cleaner does not collect dust well (a common problem with vacuum cleaners with an aquafilter). In such a situation, the Samsung vacuum cleaner brush is to blame. The turbo brush is equipped with a special roller if it is incorrectly adjusted. A similar breakdown can occur when the turbo brush is worn out.

If you have already established for sure that the vacuum cleaner does not work because it has a faulty engine, we can carry out the repair in two ways: on our own or in a service center. If you decide to adjust the vacuum cleaner motor yourself, you need to carefully disassemble it, then remove the motor and check the condition of its brushes.

If the motor does not function due to worn brushes, then they must be replaced. Frequently, the motor overheats and burns (a common cause of breakdowns with Philips vacuum cleaners), or the windings are damaged.

In this case, it is recommended to send the motor for repair to professionals. On average, it costs about 1,000 rubles to repair a motor (for Lentel vacuum cleaners, the price is slightly higher), as well as buying a new spare part, which is much more cost-effective than buying a new unit.

In order for the vacuum cleaner to serve for a long time, and not to have to buy spare parts for it, it is recommended to take good care of it. It is necessary to change the bags in a timely manner, or wash the dust collector; a turbo brush requires regular cleaning.

In general, a turbo brush, like other spare parts, is available for sale in specialized stores. The turbo brush of a Samsung vacuum cleaner costs about 600-1000 rubles (there are cheaper brushes for Miele vacuum cleaners).

A turbo brush in a vacuum cleaner rarely needs to be replaced, since regular cleaning from debris accumulated on the pile is enough for it for a long service life. In general, Samsung vacuum cleaners have a long service life and, with proper care, are considered durable.

Today they brought me a vacuum cleaner to the workshop for repair, or to be more precise, in order for me to change the motor.Everything would be fine, but it was disassembled in a salofan bag. In general, the owner disassembled it, but it was not enough to collect the mind. It is clear that as a master, such surprises from clients are not even very pleasant to me, but I also have to collect such constructors. I will say this, if you are going to repair the vacuum cleaner with your own hands, then first of all you need to know the order of disassembly and assembly, otherwise it turns out later as in the video that I posted below. From the point of view of the master, disassembling and assembling a vacuum cleaner is a fairly simple operation, but for an ordinary person, this may seem like a rather difficult task. Especially for those who want to try themselves as a master of household appliances, I suggest reading this article

First, let's see what is, in general, the whole repair of Samsung vacuum cleaners. As I wrote above, this household appliance consists of several spare parts that can be easily changed by almost anyone. Before proceeding with the disassembly and assembly of the vacuum cleaner, I want to tell you about the diagnosis of parts, that is, what determines the correct operation of the vacuum cleaner

How to assemble and disassemble a vacuum cleaner with your own hands - video

I hope you watched this very informative video and decided for yourself whether to suffer yourself or entrust this work to someone who does it all the time. If you still feel that you can, then let's proceed to the next topic of our article, namely, because of what the vacuum cleaner does not start. It is important to understand that this malfunction is inherent not only in the Samsung vacuum cleaner, but also in other vacuum cleaners that have such a problem. First, let's list those parts that are responsible for turning on the engine.This video shows one of the reasons why the vacuum cleaner does not turn on

We unscrew the bolt located in the back of the vacuum cleaner, unfasten the terminal from the control board and remove the vacuum cleaner body.

Image - DIY repair of the samsung sc8870 vacuum cleaner

As you can see in the photo, the vacuum cleaner was used to remove construction waste, which is not recommended. We take a brush and remove all construction dust.

Unscrew the bolt from the control board, disconnect all terminals and remove the board.

Unscrew 4 bolts from the engine cooling housing.

Unscrew 4 bolts from the engine compartment.

Unscrew 4 bolts from the engine housing and remove it.

We take out the old engine.

As you can see, the engine is completely clogged with construction dust, as a result of which the engine emits noise, the windings are burned out and a burning smell is felt. We will change this engine to a new one. We disconnect the terminals from the old engine and connect them to the new one, also do not forget to put a sealing rubber on it.

Assembles everything in the reverse order, do not forget to connect all the terminals and continue to use a fully working vacuum cleaner. Important! Do not use the vacuum cleaner for cleaning debris, as the vacuum cleaner will quickly fail.

Not many people know how to disassemble a Samsung vacuum cleaner with their own hands. Meanwhile, this is not very difficult. The presence of a special tool and the ability to handle it is often a sufficient minimum for success.

There are not many of them. As a rule, they are quite trivial, but when they occur, disassembly of the vacuum cleaner is required. You cannot do without it when diagnosing faults. The main reasons for the breakdown of the vacuum cleaner are the following:

failure of bearings;
wear of engine brushes;
engine failure;
malfunctions in the electronic system.

Along with the above, there may be other deviations in the work, but they, as they say, lie on the surface. For example, a fuse has blown. In this case, it is enough to replace it with a new one, and the vacuum cleaner will work again.

Before proceeding with the repair, it is necessary to prepare everything for this. First of all, you need a toolkit. Nothing unusual is included in it: a set of screwdrivers, pliers, a set of heads, an awl, a small hammer - that will be enough. Additionally, you need to have WD-40 fluid, EP-2 or Litol-24 grease, a soldering iron and a clean rag. To ring out electrical circuits, you will need an ordinary tester.

For those who are engaged in disassembly for the first time, it is advisable to have a camera with them - to record the disassembly sequence.

Disassembling a vacuum cleaner is not so difficult as it might seem at first glance. First you need to unscrew the mounting bolts from the case.

After that, it will be possible to remove the cover. Having disconnected the wires from the electronic board, we carefully separate the case from the controls. On this, the main part of the disassembly work can be considered completed. Next, we carefully take out the engine and carefully remove it from the plastic case in which it is placed.

All work must be carried out without the use of brute force in order not to break fragile plastic parts.

Since most of the malfunctions of a vacuum cleaner arise from the engine, it often has to be disassembled for repair.

This process is not difficult and looks as follows. Using a thin screwdriver, carefully remove the impeller cover. As a result, access to the nut of its fastening is opened. By unscrewing this nut, you need to remove the motor brushes and loosen the body tightening screws. It remains to carefully remove the anchor, and you can start removing the bearings. As a result of the work done at the workplace, you should get something like the following picture (pictured).

A readily available tool is usually sufficient to remove bearings, but sometimes a special puller is required. After disassembly, all parts are thoroughly cleaned of dust and dirt. Particular attention is paid to the bearing seating surfaces and the engine manifold.

The impeller nut has a left-hand thread. There are exceptions, but very rare.

Sometimes it happens that the vacuum cleaner suddenly stops performing its main function. Everything seems to work, and the dust is not sucked in. In this case, first of all, you need to get and inspect the filters. If the filters are clogged with dust, they must be cleaned. If cleaning does not work, the filters must be replaced. Before replacing, you need to turn on the vacuum cleaner without filters, and make sure that the suction power is at the proper level. If it is still small, you will have to inspect the impeller. It may happen that it is completely clogged with small debris.

At the same time, check the condition of the brushes and the engine manifold. Worn brushes must be replaced and the collector cleaned. The tightness of the hoses may also be affected, especially in the places where they are attached to the nozzles. You also need to pay attention to this.

Advice. The collector can be very carefully cleaned with fine sanding paper # 0 or # 00.

The next common malfunction is the vacuum cleaner does not turn on... There are three main reasons for this:

blown fuse;
open circuit in the network wire;
malfunction in the switch.

The fuse has already been mentioned, but to check the rest of the faults, you will need an ordinary tester. With its help, you can easily ring the wires and locate the breakage point. Then a soldering iron is connected to the case and the malfunction is eliminated.

Before starting to search for wire breaks, you need to make sure that the temperature sensor in the vacuum cleaner has not worked and that the motor has not been forcibly de-energized.

This happens when the vacuum cleaner has been in operation for a long time. No repairs are required here. After cooling down, the performance of the vacuum cleaner will be restored automatically.

If during operation the vacuum cleaner vibrates or squeals are heardgrinding, it means that there is a problem with the bearings. They need to be lubricated, and it is best to replace them immediately. The presence of sharp sounds in the bearing assembly indicates the development of its motor resource.

And the last trouble - the power wire is not tightened... Repair in this case is also not very difficult. Here the problem may most likely be in the spring. You need to get to the winding drum and inspect it. It is possible to weaken the spring or vice versa, tighten it. If everything is fine here, then you will have to remove the drum and unwind the wire from it (or vice versa, rewind it). This will adjust the tension force of the drum.

During inspection, it is necessary to check the performance of the pressure roller. Vacuum cleaners of any brand are not immune from such a malfunction, when the engine speed is no longer regulated. In this case, the problem needs to be looked for in the electronic control unit... It is simply not recommended to repair it yourself.

The process of disassembling and repairing a Samsung vacuum cleaner is not very difficult. It can be done independently with minimal knowledge of electrical engineering and the ability to handle a locksmith's tool.

In some cases, you will need to buy a new device, but most often you can try to repair it yourself at home. As a rule, the steps to repair a vacuum cleaner are few and far between. You must first disassemble the device in order to diagnose it and eliminate the malfunction that has arisen.Most often, the following malfunctions occur in the operation of the device:

when the power button is pressed, the vacuum cleaner turns on and off immediately;

during operation, extraneous sounds are heard;

the appliance heats up, an unpleasant odor arises.

Most often fail:

bearings;

motor brushes;

engine;

electronic system.

Along with the above malfunctions, the fuse may blow. To fix the vacuum cleaner with your own hands, it is enough to replace this device with a new one.Before proceeding with the repair, you need to prepare the following tools:Additionally, you will need a soldering iron and rags. You will also need a tester for ringing electrical circuits.Many parts of the vacuum cleaner are made of plastic, they are quite fragile, so you need to act carefully when disassembling and repairing.To disassemble the vacuum cleaner, you must:

1. Unscrew the fixing screws from the device case using a Phillips screwdriver.

2. Then you can remove the cover of the vacuum cleaner.

3. Having disconnected the wires from the control board, you need to separate the device case.

4. Then remove the motor from the plastic case.

Depending on the model, the devices are equipped with motors of different power and type:To disassemble the motor of a Samsung vacuum cleaner, you need to follow these steps:

1. Use a thin screwdriver to remove the impeller cover. The nut usually has a left-hand thread.

2. After that, unscrew the fastening nut.

3. Then it is required to remove the brushes and unscrew the tightening screws of the device case.

4. Then you need to remove the armature and remove the bearings.

A readily available tool is sufficient to remove the bearings, but sometimes a special puller is used. Before assembly, all elements are thoroughly cleaned of dust and dirt. Particular attention should be paid to the bearing surfaces and the motor manifold.The vacuum cleaner may not work for several reasons:

blown fuse;

open circuit in the network wire;

switch malfunction.

Methods for eliminating various breakdowns are presented in the table.You will need a tester to check this problem. With it, you can ring the wires and determine the exact location of the break.Further, this malfunction must be eliminated with a soldering iron.Before starting to search for a break, you need to make sure that the temperature sensor in the device has not worked and that the motor has not been forcibly de-energized. This happens when the vacuum cleaner is in operation for a long time.In this case, no repairs are required. After the vacuum cleaner cools down, performance will be restored immediatelyThis often indicates that there is a bearing problem.The presence of sharp sounds in the bearing assembly indicates the depletion of its resource.These parts must be thoroughly lubricated or replaced with new ones.In any vacuum cleaner there is a special compartment in which there is a wire up to 3 m long. If it is not tightened, then the problem is in the spring.It is necessary to inspect the winding drum. The spring may be loose or tightened. If everything is fine with her, then you will have to take out the drum and unwind or wind a wire around it. This is how the tension force of the drum is adjusted.The vacuum cleaner ceases to perform its main function. Dust is not sucked inIt is required to remove and inspect the filters. If they become clogged with dust, then they must be thoroughly cleaned. If cleaning does not give a result, the filters must be replaced with new ones.Before replacing, turn on the device without filters and make sure that the suction power remains at the correct level.It should be borne in mind that some models allow you to adjust the suction power. If it is not strong enough, then you will have to inspect the impeller. It can be completely clogged with small debris.Sometimes the tightness of the hoses is broken, most often in the places where they are attached to the nozzles.It is also worth checking the condition of the brushes and the collector. Failed brushes need to be replaced, and the collector should be cleaned with fine sandpaper Image - DIY repair of the samsung sc8870 vacuum cleaner

The location of the filters in the vacuum cleaner (1, 2, 3)

When diagnosing, you also need to check the operation of the pressure roller. Vacuum cleaners are not immune to violations of the motor speed control. In this case, the problem lies in the malfunctioning of the electronic control unit.

Regardless of the type of vacuum cleaner, the heart is called the engine. Television programs like to depict the creation of a vacuum, which, in our opinion, is an inept manipulation of words. The motor draws in air by the blade, the filter keeps the moving parts from dust. Each bearing is provided with an insert for this purpose. The engine is devoid of protection from vacuum ... Do-it-yourself repair of a vacuum cleaner is advisable when the heart of the device is functioning properly, there is a need to replace, modify the brushes, lubricate the bearings. It is charming that the devices are similar from the inside, like two drops of water. The mechanical part, the device for collecting dust, filters, brushes, hoses, housings vary. Accessories are an essential part of the appliance. The device of the vacuum cleaner, the basic idea remains the same!

The heart of the vacuum cleaner is rightly called a motor, traditionally a collector motor. Let's take a quick look at the design of an irreplaceable product and create a clear idea. In an asynchronous motor, a rotating field is created by the correct distribution of the phases by the windings, the winding collector commutes in series. There are unpopular exceptions. The direction of movement is determined by the direction of engagement:

The current flows, the fields work for attraction.
The current flows, the fields are repelled.

As for the question why the rotor turns exactly in this direction, not opposite when connecting the windings unidirectionally, the answer is revealed by the mutual arrangement of the brushes and stator coils, the structure of the collector. The number of coils is wound on the armature, equal to the number of contact pads of the shaft. The brushes feed a single winding at a time. Then the shaft rotates a certain angular distance, the next coil is energized. One revolution passes, the cycle begins anew.

Imagine the stator pole (so far only one - not two), located at the bottom. Suppose, at the initial moment of time, the brushes are set so that the armature pole is fed to the left of the building axis. Then, due to repulsion, the shaft begins to describe the hour hand. The axis passes the angular distance, the current begins to flow around the next winding, which managed to take the place of the previous one. This happens as long as the current exists. And there is no difference, constant or variable. The collector motor will run driven by the direction of the field. The speed of rotation is not determined by the frequency - by the design of the mechanical part, by the magnitude of the voltage.

Now if the fields are attracted, the rotation will start counterclockwise. By the time the stator and rotor poles become opposite each other, the power will be transferred to the next coil, which will begin to create the required force. The cycle is circular. Now the coils. Brush motors are equipped with a pair of stator windings for direct current because the alternating current encounters too much resistance from the inductors. This is why some brushed motors are designed with separate stator leads. It will allow you to use one instead of two windings. It is clear that the load capacity drops significantly. But losses are decreasing.

In a vacuum cleaner on the motor stator, we notice two diametrically opposite windings that help each other.Mutually beneficial coexistence is ensured by the correct direction of inclusion (wrote above). Reversing motors have a special power relay that switches the poles in proper order. For comparison, in an induction motor, a similar relay distributes the voltage phases in a different way. It turns out a reverse. The collector motor does not require a starting winding and a capacitor (one phase), which try to imitate the second winding. Simply put, the efficiency of three-phase asynchronous motors is higher. The brainchilds of Nikola Tesla and Dolivo-Dobrovolsky are used by industrial equipment, in the 90s they were replaced by collector equipment from household appliances (vacuum cleaners were traditionally supplied with graphite brushes before the restructuring).

Two brushes are used to transfer current to the armature. The difference is leveled, where the plus, where the minus, the direction is provided by the correct commutation.

Is it possible, by changing the order of connecting the brushes, to make the motor rotate in the opposite direction. The polarity of the field is reversed. This technique is used to obtain a constant voltage reverse. When doing self-repair of vacuum cleaners, remember the correct position of the contacts.

A tangential fan is hidden behind the filters for coarse and fine air purification. Air enters in the center, is discharged to the periphery, moving forward, enters the room through a HEPA filter that traps particles of a few microns (micrometers) in size. The blade is covered with a cover, the part is made in the form of curved aluminum partitions between two metal planes. Closed channels are obtained. The engine is enclosed by a plastic casing (traditionally white), in which the outlet flow path is cut.

It is interesting! Due to the presence of a tangential fan, the efficiency of the vacuum cleaner barely reaches 20-30%. With a power consumption of 1600 W, the suction will be 350 W.

Brushes are fixed in mines, it is useful for beginners to know: this is a typical pencil graphite (carbon, coal). You can, if necessary, sharpen the parts, adjust as needed, so that they become in place. If the area of contact with the collector is small, it is not scary, gradually the brushes will wear in. The tips are slightly grinded in a semicircle inward. Each brush is pressed by a spring through which the current passes, the measure will provide a long service life to the products. The carbon will work until it wears down to the ground. However, the copper collector must be kept clean. Wipe with your favorite product if necessary, remove the oxide film to a coppery shine.

The shaft is attached to the stator with two bearings. Different sizes to make it easier to disassemble the vacuum cleaner motor. The front bearing is large and the rear bearing is small. The shaft is carefully knocked out of the stator by suitable means (pneumatic puller), moderate heating helps. The bearings are equipped with anthers. Although the vacuum cleaner creates a vacuum, dirt gets in there too. The anthers are carefully removed with a screwdriver if necessary to lubricate the parts. Suitable: composition HADO, Litol - 24, EP - 2. The grease is put inside, the boot is put in place.

Do-it-yourself vacuum cleaner repair begins by removing the case. In each case, the methods are different. Filters blocking access to the engine are removed. The electrical installation is disconnected (the vacuum cleaner is unplugged), the plastic motor housing is unscrewed from the base. Remove the motor from the casing, after which the fan is removed. The nut has a left-hand thread, twist carefully. The fan is followed by a collector-cover, under which the electrical part is hidden. The further course of operations is clear from what was previously read up to the removal of the rotor.

If necessary, the bearings are racked off with a threaded remover or a hydraulic press. Aids are being used. Small balls with a diameter extending into the bearings. It is recommended to flatten on one side so as not to roll. Reverse mounting is done in a similar way.If you hold the armature by the bearing in your hand, the rotation should be fast, quiet, confident. When lubricating, the outer boot is removed, take the trouble to put new spare parts on the same side.

Other vacuum cleaners have two motors. The second is located on the brush, where it makes the villi move. Cyclonic models use a turbo, moving air does the work. Constructive refinement simplifies the manufacture of the hose, eliminates one big problem when the wire breaks in the thickness of the rubber. Of course, modern means will allow you to accurately determine the location of the incident, it is better to avoid breakage altogether. The idea of the designers, who placed the motor inside the brush, is easy to understand: there is no need to press when cleaning, the weight is decent. Do you like it, decide for yourself. In the opinion of the editors, the brush should be light to make it easier to operate.Repair of washing vacuum cleaners does not differ from that described above. However, the units contain a pump that supplies water to the hose. We will return to the question in the reviews later. As for the inlet path, the configuration does not differ from the usual one, excluding the presence of a water filter. Most look like dull boxes filled with water. In some vacuum cleaners with an aquafilter, thin streams of water hit the junction of the hose and the body. Primary dust collection is in operation. However, it is difficult to notice the malfunction. It's another matter if the vacuum cleaner is equipped with a self-diagnosis option, which will tell you the location of the breakdown.

The repair of robotic vacuum cleaners is closely related to the field of electronics. There are nothing service mechanisms at all. However, you will find the engine in a reduced size. Most of the functions are implemented in microcircuits, the memory accommodates various programs. Repairing Electrolux vacuum cleaners will seem like child's play compared to the task of adjusting the work of Rumba or Scuba by the American company iRobot (a developer of US army and police automation). A significant disadvantage of robots is the impossibility of cleaning uneven surfaces. Electronic servants lack the ability to create a vacuum ... use a rotating brush to sweep away dust.For any, even a small malfunction, it becomes necessary to disassemble the vacuum cleaner. Repairing a Samsung device is not difficult if you know how to use a special tool correctly. Do-it-yourself repairs are less expensive than professional help. A prerequisite for the operation of a Samsung vacuum cleaner is the use of multiple filters. One of them is designed to remove large pieces of debris and dust, the other collects microparticles not exceeding 0.3 microns, which protects the engine from dust. If the vacuum cleaner breaks down for the first time, you need to have a camera or mobile phone at hand in order to capture the sequence of disassembly for the subsequent correct assembly of the equipment. For the prevention of malfunctions, it is necessary to clean the filters in a timely manner.In order to fix the Samsung vacuum cleaner yourself, you should read the instructions for its operation. First you need to unplug the power cord from the outlet, pay attention to external signs to determine the location and nature of the breakdown.In a modern vacuum cleaner, the motor is completely cooled with purified air. On the case, the detachable parts are connected by means of screw clamps with six self-tapping screws, two of which hold the front part of the fastening cover, and four are located on the opposite side. The handle is fixed from the bottom with two self-tapping screws, the same amount is held by the butt. The electronic board for controlling the motor is covered by the upper housing cover and secured with four plastic locks on latches (grooves with projections).The Samsung vacuum cleaner repair technique is simple and easy to understand. You should first prepare the necessary tool:

1. Several different screwdrivers, pliers.

2. Different heads with an awl.

3.Small hammer, soldering iron with a clean rag.

4. Stock of WD-40 liquid, EP-2 or Litola-24 grease.

5. Tester, which is necessary to carry out continuity of electrical circuits.

6. Camera.

To disassemble the device, unscrew the bolts on the case, open and remove the cover. Then disconnect the wires that lead to the electronic motor control board, carefully peel off the sheathing. After that, you need to get out the plastic case in which the engine is located, and very carefully pull it out of there so as not to destroy the plastic. The main malfunctions of the vacuum cleaner are associated with this particular part, so it should be disassembled. To remove the impeller cover you will need:

1. Pry off the cover with a thin screwdriver and remove the part.

2. Unscrew the nut (usually with left-hand thread, right-hand thread is very rare).

3. Remove the motor brushes.

4. Unscrew the body tightening screws, carefully pull out the armature.

5. Remove the bearings, remove the impeller.

Do-it-yourself removal of parts is done with the existing tool, but there are exceptional situations when you cannot do without a special puller. When the disassembly is completed, all parts must be thoroughly wiped, cleaned of dust, and dirt should also be removed from the bearing surfaces of the bearings and the engine manifold.

When working with a Samsung vacuum cleaner with clogged filters, dust is not sucked in. A few minutes after its start (from 1 to 15), the power is automatically reduced. In this case, in the presence of protective automatics, the emergency thermostat will turn it off, and if it is absent, the device will burn out. Typical signs of clogged vacuum cleaner filters are poor draft, strong hum and heat. Before proceeding with the disassembly of the device, all filters should be checked, if necessary, replace them or clean (certain types need to be rinsed) and refilled.

If you cannot remove dirt, you need to remove these elements and turn on the vacuum cleaner without them to make sure that the suction power is normal. With a small one, you will need to clean the impeller from the accumulated small debris, and then check the condition of the turbo brush and the engine manifold. Unsuitable brushes must be replaced and the manifold must be cleaned with fine N0 or N00 abrasive paper.

If the vacuum cleaner is used for a long time, the fuse may blow and the unit will not turn on. In this case, it should be inspected and replaced before starting the start. The next common breakdown is a break in the power cord. The vacuum cleaner will not work if it has a faulty switch. To identify this defect, you will need an ordinary wire continuity tester to determine the location of its break. First, you need to make sure that the thermal sensor in the vacuum cleaner has not worked, which could forcibly de-energize the engine. You can eliminate such a malfunction with a soldering iron in a few minutes. The vacuum cleaner will cool down and turn on automatically.

If at the time of operation the device begins to vibrate, emit unpleasant cutting sounds, grinding, this means that the bearings should be lubricated or replaced with new ones. Such signs indicate wear of parts.

Also, the power cord may not be pulled in. This is due to a weakening of the spring in the winding drum or a tightening of the cord. To fix the problem, you need to remove the drum, inspect it and solve the problem by rewinding the cord. If the pinch roller does not work, you must contact a specialist. The vacuum cleaner is assembled in the reverse order.
