Now we will fix the most common breakdown of Samsung vacuum cleaners.
In this case, the vacuum cleaner does not turn on. Most often, the engine fails. Now we are going to replace it.
First, take out the dust container
Unscrew the four screws at the front of the case
Next, unscrew the countersunk screw hidden under the film
Next, remove the cover of the vacuum cleaner
Vacuum cleaner without top cover
We take out the engine together with the casing
We remove the sealing gum and take out the faulty engine. A detailed examination reveals that he has burnt lamellas, one of the most common causes of malfunction of vacuum cleaner motors.
We take the previously purchased new engine and insert it into the place of the old engine and assemble in the reverse order.
If everything is assembled and connected correctly, then the vacuum cleaner will work as before.
The most common reason for the breakdown of a vacuum cleaner is the wear of its internal parts and mechanisms. 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 immediately
This 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 in
It 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, 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
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.
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 have to collect such constructors as well. 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
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

Now let's talk about how to change the bearings of the vacuum cleaner motor. It is almost impossible to talk about it, you just can't show it on your fingers.Although the topic is quite relevant, I, as a master, would advise to change the motor, not the bearings, but given the fact that we still do not live in the wild west, but on the territory of the former Soviet Union, and many citizens of this huge region simply do not have the opportunity to buy this spare part , but the replacement of bearings is still cheaper, I decided to shed some light on this dark question. To begin with, you need to know in which cases the bearings should be changed. First of all, you need to pay attention to excessive sparking, if it sparks strongly, then the replacement is unlikely to help, although I have had cases when, after the operation, the engine worked no worse than the new one. The appearance of noise also indicates that it is time to change the bearings. Vacuum cleaner bearings should be of high quality, preferably from SKF. Well, how this is done in general, you will see below, after watching my video and do not be very upset if, after replacement, the engine sparks or makes a lot of noise - it means it did not work out, but we tried

I hope my article helped you. The most important thing is to know what to do for what and how. With this information, you can probably do everything that I did in my videos. Of course, to me, as a master, it all seems simple, maybe it’s so, but I also didn’t know how to disassemble the vacuum cleaner, and if you also take into account the fact that about such information that is given to you in this article, at that time, when I started and there was no question, now it will be much easier for you than for me once. The only thing I want to add is that be careful and follow safety precautions, otherwise it beats a lot
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 heard grinding, 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.

Igor Shubin at his site in the village "Lesnoye"
Igor was looking for a forest suburban area, and among others he got this one. And not only is it an impassable forest, but also in the middle of the site - 6 meters of slurry from a small stream. Because of this swamp, the future owners could not cross to the other side of the site to inspect the boundaries of the property.

So I lived to see my workshop, which needs to be equipped and supplemented with various tools for a long time and persistently.
But the main thing is there is a warm room, although not your own, there is where to work until they are kicked out.
This warehouse is quite spacious, if you remove everything you do not need, so you have to do a lot to at least somehow get to work. And the first thing I did was take out too much and started assembling a large desktop.

The first attempts to make something out of the brought slabs. Although there may be attempts, the material costs money and the margin for error is as much as there is money in your pocket. Train at your own expense, as they say.
Therefore, each board is carefully examined and measured, the proverb about seven times measure in action.
The work itself is not tricky, creative, there are several boards and you need to pick them up so that it looks beautiful and there is no overrun. All adjustments to the size and trimming are done with the minimum possible material removal, simply sawed off a bit here, cut it off a little there with a chisel.
A person very quickly gets used to good things, so anyone who has ever tried to use a vacuum cleaner is unlikely to want to take up a broom again. However, like any technique, vacuum cleaners tend to break down at the most inopportune moment. Not every housewife is capable of single-handedly troubleshooting a Samsung, LG, Phillips or other vacuum cleaner. Nevertheless, there are breakdowns that can be eliminated on their own without resorting to the help of specialists.
Before you start repairing a Samsung vacuum cleaner with your own hands, you need to try to determine what exactly broke there. Correct diagnostics is very important, because the speed and cost of repair directly depends on it. The design of the vacuum cleaner is quite simple, therefore, before paying money to the master, you can try to fix the malfunction yourself.
It should be noted that a breakdown is not always associated with an engine malfunction. Such a malfunction can be identified by the sound of the unit running. If the vacuum cleaner hums, whistles, makes intermittent sounds and throws out dust from itself, most likely you are out of luck - the engine is "covered". But it happens, for example, that the vacuum cleaner seems to work, but the garbage pulls badly - then, most likely, the hose or filters are to blame. Let's take a closer look at some of the typical malfunctions of this very useful home assistant.
As we have already found out, if the vacuum cleaner does not draw dust well, then you, most likely, will have to repair the vacuum cleaner hose (you have Samsung, or other brand products - it does not matter). First of all, make sure that nothing is stuck in it - foreign objects caught in the hose greatly reduce the draft. Simply put, peek into the hose and remove the blockage.
If you are sure that the hose is not clogged, carefully inspect it and check the integrity of the corrugation. Very often housewives are too lazy to bend down to rearrange the unit from place to place, and they simply drag it around the room "by the tail". From this, gaps arise between the turns of the corrugation, as a result of which the thrust decreases. If you find a gap, take duct tape and wrap the gap tightly in several layers. Of course, such repairs will not be enough for a long time, and over time the hose will still have to be replaced, but for some time it will still serve you.
If everything is okay with the hose, check all filters and waste bag - they may be heavily soiled.Clean the filters thoroughly and replace the bag with a new one. Also, do not forget to check the position of the power regulator - it may be out of order. Return it to the desired position.

In this case, do-it-yourself repair of the Samsung vacuum cleaner will consist in a thorough examination of the brush. Make sure it is low enough to contact the floor - if it is not, pull it out all the way. Examine the brush itself - its fibers are probably too worn out and will need to be replaced.
Turn on the vacuum cleaner and inspect the brush in working order - if it does not spin or rotates weakly, you will have to work hard. In the first case, the bearings are probably jammed. Disassemble it and check if there are threads or hair wrapped around the ends, remove them. In the second case, a weakening of the brush belt is possible - disassemble it and change the part to a suitable one for your model. Please note: although spare parts for Samsung vacuum cleaners are very often interchangeable for different modifications, it is best to choose the right ones for your model.
If you plugged the unit into an outlet, and nothing happens, then the repair of the Samsung vacuum cleaner (with your own hands, of course) should begin with a thorough examination of the electrical part of the device. First, make sure that the outlet itself is working - to do this, plug in another, known working device. If everything is in order - inspect the vacuum cleaner cord, look for scuffs, cracks, kinks or other damage. Disassemble the plug and carefully inspect the connection with the cord. Use a control or an electrical tester to "ring" the wire - it is probably burnt out.
If all of the above actions did not give a result, it means that the brushes are to blame or the engine burned out. This part of the repair is already classified as more complex.
The reason for such a breakdown may be a hose (for Samsung this is an ordinary case): between the turns of the corrugation, dirt and debris often get stuck, which eventually begins to emit an unpleasant odor. Rinse the hose thoroughly with a jet of water, preferably with high pressure and detergent. After that, be sure to dry the corrugation well before using it again.
Belt can be another source of unpleasant odor. Check its tension, tighten if necessary or replace with a new one. The smell of burnt rubber will disappear.
It so happens that during seemingly normal operation, a strong noise is heard and the unit beats are observed. In this case, the repair of the Samsung vacuum cleaner (it is not always possible to manage here with your own hands, but it is still worth trying) will be as follows:
If you have a vertical model of a vacuum cleaner, then, most likely, a damaged fan is making noise - inspect it. Replacing and balancing the fan yourself is not an easy task, it is best to entrust it to a specialist.
If the vacuum cleaner is washing, inspect the pump that pumps water into the hose. The repair recommendation is the same - to a specialist.
In most models of vacuum cleaners, the reason for the rattling is "broken" bearings on the brush. If you are confident in your abilities, you can try replacing them yourself. Take a roller and carefully unscrew the end cap, remove the metal shaft from it. Holding it with pliers, unscrew the next end stop, then replace the bearings, anthers and gaskets. Put everything back into place.
Now we come to the most important and difficult breakdown - repair of the motor of the Samsung vacuum cleaner. To make sure of this, you need to disassemble the vacuum cleaner. Carefully remove all body protectors and locate the motor itself. Now, very carefully, observing all precautions, turn on the vacuum cleaner. If the cause of the breakdown lies in the motor, then most likely you will see a sheaf of sparks emanating from the engine. There may be several reasons for this:
wear of brushes;
turn-to-turn circuit in the winding;
increased load on the "engine".
So, in order. To replace the graphite brushes, first of all, unscrew and remove the plastic caps and remove the springs. We take out the brushes themselves and insert new ones.Next, we perform all actions in the reverse order - insert the springs, tighten the caps. In order for the brushes to work properly, they need to be ground in. This can be done by stretching a fine sandpaper between the brush and the collector. In this case, the abrasive of the sandpaper should be turned towards the brush and, as it were, comb it off a little.
If all the manipulations done have not been successful, and the sparking of the engine continues when turned on, then the engine has shorted. It will not work to make an independent repair of the motor of the Samsung vacuum cleaner (and any other one too) at home, you will have to carry it to the service.
Another reason for engine failure that you can try to fix at home is bearing replacement. It is very easy to check whether this should be done. Take the motor in your hand and lightly shake it by the armature: if you notice that the shaft is wobbling from side to side, then replacing the bearing cannot be avoided. To do this, you need to remove the brushes and unscrew the screws that tighten the body. Then remove the motor covers one by one, using a small hammer and screwdriver to help yourself. Follow this procedure very carefully, otherwise you risk damaging the winding. Carefully, helping yourself with tools, remove the bearings (preferably both at once) from the armature shaft. With extreme care, use a hammer and a tube of a suitable diameter to push the new bearings into place and assemble the motor.
One little tip: Before deciding to disassemble the engine, sketch out a wiring diagram. Believe me, this will come in handy.
As you can see, repairing any household vacuum cleaner can be very easy. The main thing is to remember that spare parts for Samsung vacuum cleaners or equipment from other manufacturers must be of high quality. And if you doubt your abilities even a little, it is still better to entrust the repair of equipment to professionals.
The problem that the keyboard does not work in BIOS, users usually notice when reinstalling the operating system, when it is required to set the boot priority, or in case of changing additional settings of the first.
If your laptop beeps when you turn it on, the reasons for this may be different. Let's try to figure them out. Computer equipment is often subject to various breakdowns. The fact is that a laptop consists of a large number.
No housewife can imagine herself without an automatic washing machine. The assortment range allows you to choose a model that is most suitable in terms of dimensions, technical capabilities, and in accordance with the existing bureau.
Owners of domestic off-road vehicles "Chevrolet Niva", however, like all other Russian-made cars, in most cases prefer to repair their iron horses with their own hands.
We will describe how to repair Samsung monitors with your own hands with a malfunction, which consists in the fact that the device does not turn on, the indicator on the front panel is inactive. Consider several options for damage.
Steering is an important part of any car. The traffic rules prohibit the operation of motor vehicles with various breakdowns in the steering system. It is very important even with insignificant p.
After loading the drum with laundry, you find that the washing machine does not start? It may not respond at all to manipulations with buttons, not respond to the launch of the selected program, or the indicators begin to work in.
Gadgets have become an integral part of the life of a modern person. But with them very often various problems arise. For example, from time to time, users complain that their ASU tablet does not turn on.
The car has become an integral part of our life. He often helps at the right time. However, it also happens that a person is late somewhere, and only a car can help out. But, getting into the car, the pony driver.
A car cigarette lighter has long ceased to be used only for its intended purpose. Today, its socket is actively used by drivers as an on-board socket, from which additional electrics work.
The SAMSUNG SC 8854 vacuum cleaner was purchased by us five years ago. And all this time he served us impeccably. But recently, during the operation of the vacuum cleaner, some kind of strumming began to be observed. Then he got up altogether. After a short manipulation, that is, on-off, twisted, knocked, he came to life. But not for long. The next time he worked, he got up again, and a smoke with a pungent smell of insulation flowed out of him. That's it, the vacuum cleaner is out of order, or rather: his email. engine.
After not long deliberation, it was decided to buy a new email. motor for the Samsung vacuum cleaner. And do it yourself repair the vacuum cleaner. And then the question arises: How to disassemble this vacuum cleaner. In fact, there is nothing complicated about it.
The first thing to do is remove the dust container and rear filter. Then remove the wheels of the vacuum cleaner. To do this, you need to pry off the decorative cap that covers the wheel mount with something sharp (for example, an awl). And the fastener is an ordinary screw, which is unscrewed with a Phillips screwdriver.
The wheels are removed, you can start disassembling the body of the vacuum cleaner.
The case consists of two halves, to separate them we unscrew five screws. Four of which are located under the dust container. And the fifth is hidden in a recess where the telescopic rod of the Samsung vacuum cleaner is placed.
There are also latches in the area of \ u200b \ u200bthe wheels, which are unfastened with a flat screwdriver. After unscrewing all the screws and unfastening the latches, remove the top cover.
Do-it-yourself vacuum cleaner engine repair is a very troublesome and long task. And not everyone can do it. Therefore, it was decided to buy a new one. Nowadays, buy email. the motor for a Samsung vacuum cleaner is not difficult, there are a lot of such offers on the Internet. The main thing is not to rush into the choice. Many motors are no longer in production, and those remnants that are still in store warehouses cost a lot of money. So in my case it happened.
But I found it versatile and almost half the price. The main thing is to fit the impeller diameter and height, as well as the location and shape of the holes that are located on the motor housing cover. They (holes) are designed to keep the motor from spinning in the "kinder surprise" container. *
At this, the replacement of the vacuum cleaner motor can be completed, it remains to assemble the vacuum cleaner in the reverse order .. Be careful, make sure that all covers fit tightly. Otherwise, it will suck in air from the outside, which will entail a loss of suction power from the surface of the carpet or floor.
Based on the above, we can conclude: repairing a SAMSUNG vacuum cleaner with your own hands is not a difficult undertaking. Better to do it yourself for free than to pay others for it.
Thank you for your attention! Long years of service to your vacuum cleaner!
