Bosch vacuum cleaner DIY wire rewinder repair

Details: Bosch vacuum cleaner DIY wire rewinder repair from a real master for the site my.housecope.com.

In this video, I tried to talk about how you can repair a vacuum cleaner, or rather its cord winding mechanism, with your own hands. A common problem with the failure of the winding mechanism is the breakage of the flat spring. You can learn how to restore it from the video. #repairmechanismvacuum cleaner cable reel #vacuum cleaner repair

The cord stopped stretching at the vacuum cleaner - it stretched out for half a meter and stalled. Button rewinding does not work.

We'll have to disassemble the entire vacuum cleaner because this unit is located in the bottom. What could have happened. The best option. Under the retraction pedal (lever) there is a roller with a rubber wheel, it is warped or jammed and the drum with the cord does not unwind. The second option. Worse, the spiral spring burst. It is at the very bottom, under the drum. To get to it you will have to disassemble everything down to the bolt. These are the two most common breakdowns. Maybe some other small things (something got under the winding drum and jammed) But you can find out the reason only by disassembling the vacuum cleaner.

The cord is usually wound on a special roller, if it is jammed or broken, then it should be repaired (or replaced).

If the vacuum cleaner is not very old, then there is a high probability that by contacting the household appliance repair service, they will find something suitable for you. Putting it on after disassembling the device is a matter of a few minutes.

If the vacuum cleaner is old, you will have to invent something, tinker, trying to find something similar.

In any case, such a breakdown, in addition to minor inconveniences, does not affect the operation of your vacuum cleaner. Well, as a last resort, you will have to wind up the wire by hand and, pulling it off with an elastic band, put it next to the vacuum cleaner.

A similar problem with the breakage of this very “winder / rewinder” of the vacuum cleaner cord is not so rare. After several months of use, the cord either stops coming out normally, or does not come out at all. In addition, the button that winds the cord back stops working.

Indeed, the main reason for such problems / breakdowns is a burst washing spring. And to fix it, you first need to disassemble the vacuum cleaner and get to the spring and replace it. It may be that the rewinder has broken.

In any case, if you are not friends with household appliances, then it is better to take the vacuum cleaner for repair.

It all depends on how old the vacuum cleaner is and how rare it is, because most likely you will have to change the part, the reel itself, if you can call it that. In any case, I would take the vacuum cleaner to the service, because if you climb in there yourself and try to fix it, you can do worse. If at the moment there is no finance to be engaged in repairs in the service, you can temporarily fold the cord and tighten it with an elastic band, this does not violate the main function of the vacuum cleaner.

Although if the equipment is old, you can climb yourself, perhaps something is simply stuck there or this reel has fallen from its place. Try to disassemble.

The cord in the vacuum cleaner is curled up by the machine, I can't pull it out right away, it twists it back, how can I fix it? | Topic author: Lyudmila

Stanislav he is not defective, he just broke 1.

Galina Probably a defective twisting mechanism - Put the clothespin on the cord when you unwind it and then remove it.

Yulia Pryshchepka to help you.

Locking roller dirty. in the mechanism for reeling the cord of the vacuum cleaner. ...

The winding mechanism of the connecting cord works as follows. When the cord is wound from the reel, the springs are charged, accumulating potential energy, and the brake rocking device presses the connecting cord against the shoulder of the body and does not allow it to be drawn into the body. When the connecting cord is wound on the reel, the brake rocker is squeezed out under the action of the operator and does not prevent the cord from being pulled into the body “due to the accumulated potential energy of the springs

When the connecting cord is wound from the coil and when it is wound, the voltage from the electrical network is constantly supplied through the cord, current-conducting springs and leads to the electric motor.

By eliminating sliding contacts made of expensive metals, the cost of the connecting cord winding mechanism is reduced.

Like other household appliances, cleaning equipment, to which the vacuum cleaner belongs, requires careful handling and personal care, limited only by keeping the said item clean. However, a person rarely gives attention to their "electric assistants", which sooner or later will necessarily lead to their breakdown.

An unpleasant situation that can happen when the vacuum cleaner engine fails to work can indicate both a minor malfunction and a breakdown that can no longer be fixed, but to determine the reasons for the failure of the equipment, you still have to disassemble it. It should be borne in mind that foreign technology is not it is so difficult to repair, how difficult it is to disassemble and assemble, therefore DIY vacuum cleaner repair will require from the "home craftsman" not only confident knowledge of electrical engineering, but also fairly developed logical thinking.

If the decision to take on the repair of the vacuum cleaner was weighed and it was possible to find all the screws and latches, bypassing the mechanical damage to the equipment case, then I would like to advise you to start identifying the causes of the malfunction with minor breakdowns, since it is they who interrupt the work of household appliances most often.

In general, you need to start by cleaning the vacuum cleaner from dust and dirt, for which it is enough to wipe all units and parts with alcohol-containing substances (cologne, vodka), after which you can start working with the tester. First of all, ring out the power cord of the vacuum cleaner, which is sometimes sufficient. If the wire does not ring, then there is a break somewhere.

As a rule, an open circuit can be found inside the coil winding the mains wire - by making vacuum cleaner repair Daewoo, we decided to show what happens to the wires visually, for which we will tell you how the described malfunction is eliminated.

Having unscrewed the screws securing the cover of the vacuum cleaner to its body, you should remove the protective casing of the electric motor, which is available only in some models of this cleaning equipment. The sowing procedure will facilitate access to the wires connected to the motor.

Then you should disconnect the terminals from the ring contacts of the coil of the mains wire, not forgetting that the contacting parts can be easily damaged, therefore, be careful in this case. Moreover, given the fact that repair of household appliances in Tiraspol relatively inexpensive, we strongly recommend that you take further action only with full confidence in your abilities.

So, having disconnected the terminals, it is necessary to move the entire wire winding mechanism away from the vacuum cleaner body with a screwdriver, while lifting the entire coil up. Then you should unfold the wire and visually determine the place where the electrical circuit can be broken.Having done the above, you should strip the wires a little closer to the plug of the cord and check with a tester the circuit from the stripped wire to the plug and to the ring contacts of the coil. If there is a connection with the plug, but there is no coil with the contacts, then the wire can be safely cut, thereby making it a little shorter.

However, for this it is necessary to disassemble the coil by unscrewing the screws holding the two halves of this unit together. At the same time, I would like to note that in no case should you unscrew the screws securing the coil spring plate. The fact is that this spring is easy to remove, but almost impossible to put back. The vacuum cleaner, of course, will work without it, but the wire will have to be rolled up around the case, and not hidden inside the equipment.

By dividing the coil body into two halves, the master gains access to the terminals of the mains wire, which should be disconnected from the ring contacts, while memorizing their position. I would also like to note that the old terminals are disposable, therefore, by cutting off the damaged section of the wire and stripping its ends, you will need to install new "mothers" on it.

Having done these simple manipulations, it is necessary to install the power cord of the vacuum cleaner into the reel so that it is in the starting position. The fact is that it is precisely this position that allows the cord to remain stationary inside the coil when the user of the vacuum cleaner spins the latter before cleaning an apartment, house or office.

By the way, it is the abrupt movements when pulling the cord, the unwillingness to switch to another outlet on time and careless handling of the vacuum cleaner that lead to the breakage of the wires inside the braid. It is equally important that there is no need to press the buttons of the described equipment with force, to overheat its motor, if there is no desire to look for a service that provides repair of vacuum cleaners in Tiraspol, because the cleaning equipment can serve without any failures for 5-8 years.

Your vacuum cleaner will last for many years if you use it correctly, maintain it and follow the manufacturer's recommendations. But there are times when a household appliance breaks down. If the vacuum cleaner is under warranty, then you need to contact a specialized service center.

If the vacuum cleaner has gone out of warranty, then in the event of a breakdown, it is not necessary to throw the device into the trash. You can also repair the vacuum cleaner on your own, if you have some experience in electrical repair work. Repair of some parts, for example, replacement or prevention of the electric motor of the vacuum cleaner, can be done at home without calling the master. The device of vacuum cleaners is the same for most manufacturers. Therefore, for example, we will consider the repair of a vacuum cleaner using the example of the Samsung brand.

Like all mechanisms, the vacuum cleaner has faults that are most common. Attention should be focused on them. Household vacuum cleaners also have such malfunctions.

Clogged vacuum cleaner filters.
Broken supply wire.
Engine defects.
Damage to the vacuum cleaner hose.

Dirty vacuum cleaner is one of the most common causes of poor vacuum cleaner performance. It is characterized by the fact that the traction of the vacuum cleaner deteriorates markedly. To bring the vacuum cleaner to normal working condition, it must be disassembled and cleaned. The disassembly scheme of the vacuum cleaner is different for all brands and brands. But the principle is about the same.
How to disassemble and clean a vacuum cleaner video below:

The power plug of the vacuum cleaner is plugged into a power outlet, but the vacuum cleaner does not turn on. And it doesn't even show signs of life. So you need to look for the reason in the voltage supply to the vacuum cleaner.
First you need to make sure that the outlet itself is working. You can check the presence of voltage in the outlet using a voltmeter. This is the most correct method.If the voltmeter was not at hand, you can use another, obviously serviceable electrical consumer. It could be a table lamp or something similar. If the outlet is working and there is voltage in it, we proceed to repair the vacuum cleaner. The vacuum cleaner must be disconnected from the outlet and its power cable must be inspected. The wire usually breaks at the junction with the plug or the vacuum cleaner itself. If the fault is not visually found, then the vacuum cleaner will have to be disassembled. You can see how to disassemble the vacuum cleaner video above. Next, check the integrity of the cores of the supply wire using an ohmmeter. If the wire is broken, then it must be replaced with a new one. If the wire is intact, then use an ohmmeter to check the vacuum cleaner switch and so on to the engine. Repair or replace them if necessary.The first thing to think about repairing is engine noise. A lot of dust may have accumulated inside the appliance. To check this, you first need to disassemble the vacuum cleaner.
Required tools:
To parse without damaging the vacuum cleaner completely, you will need:

Two Phillips screwdrivers for large and small screws, and two flat;

Tweezers.

Pliers or wire cutters.

Socket head 12.

Locksmith vice.

Engine lubricant, if required.

Important. To prevent injury to your Samsung Vacuum Cleaner, follow the mandatory safety precautions. During all manipulations, the device must be turned off. Only after the voltage does not flow into the vacuum cleaner, you can begin to disassemble it.

You need to disassemble the vacuum cleaner in a strictly defined order:

First, the dust container and two filters are removed: front and rear;

Use a Phillips screwdriver to unscrew all the bolts under the removed filter;

Now you need to remove the body of the vacuum cleaner. To do this, first, its front part is raised and only then the rest. The body can be removed easily, without great effort;

You can start a little cleaning of the body of the vacuum cleaner and the body of the electric motor. All dust is removed with a simple brush or dry cloth.

For convenience, cleaning work is best done outdoors.The next step in repairing a Samsung vacuum cleaner is to inspect and repair the motor of the device.
To repair the motor of a Samsung vacuum cleaner, you first need to disassemble it. This is done as follows:Reassemble the vacuum cleaner in reverse order.How to disassemble a vacuum cleaner video, see below:

The sequence of actions is as follows:

We disassemble the body of the vacuum cleaner. First, remove the bottom cover, which is attached with 6 screws;
We remove the control module. To do this, disconnect all terminals from it. In order not to make a mistake with the location of the terminals during reassembly, we recommend that you draw a diagram of their connection or take a photo. The board itself is held on one side by an ordinary self-tapping screw, on the other - a metal clip, which should be wrung out with a screwdriver;
We call the microswitch with a tester (the nearest pairs of contacts are called) to make sure that the problem is in the button;
We solder the old switch by gently prying it with tweezers or a small flat screwdriver (we push it between the board and the microswitch);
We clean the four mounting holes from the old solder with an awl;
We install a new microswitch into the holes until it stops and grab it with a soldering iron. We cut off the extra "paws" of the contacts with side cutters;
Putting it all in reverse order

Option 2: Repair the microswitch.

This method is suitable if you have no experience with a soldering iron. To restore the button, you need to clean it from oxide deposits.

To do this, you need to remove the top plate, which is attached to non-separable plastic clips in four places. They can be cut off with a clerical knife.
Next, you need to remove the button itself and get a thin metal membrane. It, as well as the contacts under it, should be cleaned with zero sandpaper.
The metal plate can be put back on with super glue or hot melt glue.
Then everything is going in reverse order.

In some cases, when the button is not strongly oxidized, you can solve the problem without disassembling it. To do this, it is enough to wipe the contacts with technical alcohol (ethanol). In this case, it is necessary for the alcohol to penetrate into the button. During the cleaning process, the button must be pressed vigorously.

VIDEO INSTRUCTION

Breakage of the vacuum cleaner's cord retractor mechanism is a common occurrence. It usually starts with the fact that the wire stops coming out and reeling normally, and then it is not fixed at all (it doesn’t get it).If the button for winding the wire of the vacuum cleaner has broken, i.e. the winding mechanism does not work, you will have to completely disassemble the vacuum cleaner in order to establish the cause of the problem. And it, as a rule, is connected with a rubber roller that fixes the drum with a cord.

Very often, in the process of intensive use, the retainer roller wears out and it gets jammed or it ceases to hold the drum.

You can fix the problem by replacing the roller or by building up the support platform by gluing a rubber plate, as shown in the video:

VIDEO REVIEW

Good afternoon, dear fellow electricians!My name is Andrey, and I have this question for you. The other day I read an entertaining article on your website about the repair of washing machine engines. The material was presented in great detail and clearly, so that even I, who was not at all knowledgeable in this person, could figure it out. I went further and began to look for material on the problem, but with a vacuum cleaner, which I have, but I could not find anything similar.In general, the mechanism for winding the wire in the vacuum cleaner is junk. When you press the button, the winding goes on, but the wire stops a meter from the body and this makes me terribly angry.Tell me if it is possible to repair it without resorting to the services of a service center, where the price will most likely be broken. I think that every second person faces a similar problem, and the material will be in demand. Thanks in advance! Image - Bosch vacuum cleaner DIY wire rewinder repair

Good day, Andrey! We hasten to please you and inform you that there is a way of such repairs and for its implementation you only need a Phillips screwdriver. In extreme cases, you will have to resort to using pliers, but more on that later.

The wire winding mechanism itself is extremely simple. It consists of a large coil, a fixing unit and a flat metal spring, with which, in fact, the problem arises.

Advice! Before proceeding with the repair, you, of course, need to disassemble the body of the vacuum cleaner in order to get to the desired part. It is not difficult to do this and the actions are usually intuitive, but if in doubt, then look for schemes for parsing your model on the Internet.

Why does the spring stop pulling? It's simple - over time, due to constant tension, it relaxes and loses the level of the initial tension. This means that our task is to properly charge the spring.

We remove the mechanism itself from the case, having previously disconnected the terminals through which the cord is connected to the engine;
Pull the cord a little and pull it out of the groove that keeps the plug from winding up further.
We wrap the elongated part again around the coil and return the plug to its place.
If the design of the coil is such that it does not allow such manipulation, then we pull the cord a couple of meters and make a loop around the coil with a wire, after which we tighten it back.

After these manipulations, we check the mechanism. If the effort is still not enough, then make another turn, but be careful and do not over-tighten the spring.

If you cock it too hard, then there may be cases of injury from the plug, which often happened on Soviet vacuum cleaners, where very powerful springs were installed.Also, being constantly cocked, the mechanism very quickly loses its functionality again.

Since we have tackled this topic, let's consider the option when the wire does not retract at all. This happens when the spring in the mechanism bursts. How to be in this case.

Of course, you can go to a service center and order a new part (the price of such a solution can be quite high), but this is not at all necessary, since it is still possible to restore the old one with your own hands if it breaks down closer to one of the ends.

We disassemble the vacuum cleaner in the same way and remove the mechanism.
We release the spring from the retainer and remove it.
You will immediately notice that along the edges the spring is attached by small bends that are wound into special slots. The thought immediately comes to me that for repair it is necessary to remove the torn piece and make the same bend at the free end. That's right, but we wouldn't be scary if it were that simple. The fact is that when you try to bend the metal with pliers, it will break immediately. To prevent this from happening, there is one little trick.

So, we take the spring and begin to heat the desired end of it over the gas burner (an ordinary kitchen stove will do just fine).
Kalim is red hot - no longer needed.
As soon as it takes on the same color as in the photo, we put it aside and let it cool naturally, without cooling it in any way.
The cooled metal can be easily bent, so we take the pliers and give the spring the desired shape.
After that, it is necessary to make a fitting - if everything is normal, then we again heat the bent part, but this time we immediately lower it into cold water. This will harden the metal again and lose its elasticity.
We carefully wind the spring back onto the coil, constantly holding it with our hands so that it does not jump out, and fix it back with a plate.

That's all we can answer the question of how to remove the wire in a vacuum cleaner. The procedure is not complicated and will take half an hour from you. In addition, he advises to look at the video in which you can see some of the details.Everyone who appreciates the comfort and cleanliness of their own home understands that a vacuum cleaner is an irreplaceable assistant, with which you can not only rid your home of dust and fine litter, but also wash the floors. All this is of course good, but only for the time being, while your vacuum cleaner works flawlessly. But as soon as it breaks down, we are deprived of the same faithful and reliable assistant, without which any cleaning turns into a living hell.A very common reason for the failure of a vacuum cleaner is damage to the power cable. Despite the fact that this part is quite simple, not every housewife is able to properly repair the vacuum cleaner wire, and even more so to completely replace it. After all, damage to the cord can be not only visible, but also hidden behind the cable winding, therefore, you can find a break or burnout only with the help of a special tester. In addition, improper connection of a broken cable can lead to a short circuit, which can cause even more damage to your vacuum cleaner, permanently and irreparably damaging it.

If the cable of the vacuum cleaner begins to crumble, and this can happen for various reasons, for example, from prolonged exposure to sunlight, then in these cases a complete replacement of the cord in the vacuum cleaner is necessary.The length of the vacuum cleaner wire can vary from three to fifteen meters, depending on the model and purpose of a particular device. Therefore, all modern vacuum cleaners are equipped with a very convenient mechanism that allows you not to wind the power cable manually, but send it directly to the body by pressing a button.It often happens that this mechanism breaks down and many people in this case do not go to specialized workshops, but simply wind the cord around the body of the vacuum cleaner.Not only will this activity take you some time, especially if the vacuum cleaner cord is very long, it is strongly discouraged to do so.Winding on the case or winding the wire on the hand not only spoils the aesthetic appearance of the equipment and adds dimensions to it, but can also lead to its fracture and short circuit. Therefore, in the event of a drum breakage, it is simply necessary to repair the winding of the vacuum cleaner cord, unless, of course, you want your faithful assistant to serve you for a very long time.Experts believe that the very common reasons that require repair of the vacuum cleaner cord winding mechanism are:

Strong blow to the cabinet or the cleaner falling off a ladder.

Sharp wire tension. As a rule, a breakdown occurs after the user wanted to stretch the cord as much as possible and did not calculate his strength at the same time.

Breakage of the return spring.

Breakage of the plastic parts of the drum and other reasons that are revealed after the diagnosis of the vacuum cleaner.

In some cases, it is simply not possible to repair the coil of the vacuum cleaner cord. In this case, a complete replacement of the mechanism is required. The Firstservice service center works closely with European, Asian and domestic manufacturers of household appliances, therefore, spare parts and components for vacuum cleaners of various brands are constantly available in our warehouses. This means that if it is impossible to repair the coil of the vacuum cleaner wire, then our qualified specialists will easily replace it with a similar original mechanism that will serve you for more than one year.Whether it is minor repairs to the vacuum cleaner's cord reel or more complex motor repairs, our skilled craftsmen will deal with any problem as soon as possible. Indeed, for this, our workshops have all the necessary equipment and diagnostic stands, with the help of which you can quickly identify a malfunction and make a really high-quality repair of your household appliances.Also, our service center pleases its customers with pleasant bonuses.

This bet will increase by 1% every time you bring us your faulty equipment. Image - Bosch vacuum cleaner DIY wire rewinder repair

Regardless of the manufacturer and type of vacuum cleaner, the main difference lies in quality, power and design.

The most important thing in a vacuum cleaner is the electric motor, which creates a vacuum and, as a result, sucks dust and various particles through special filters through which only air passes.
In different types of such devices, these filters are different, and flasks and just bags and cyclone-type vacuum cleaners.

But it is the engine and, occasionally, the electronic power (rpm) control circuit that requires the most attention in this whole device.

Do-it-yourself engine repair is not difficult to carry out if the breakdown is simple and the engine is still running but you can hear a heavy engine stroke (when turned off) or the engine starts to rattle or buzz strongly, it happens that the vacuum cleaner gets very hot in a short period of time.

The heart of the vacuum cleaner, as we have already figured out, is the engine and, as a rule, the collector.
What is such an engine?
The motor is housed in a housing where the fan impeller blades are hidden. It is of the tangential type, where air is drawn in at the center and exits through the periphery and already exits through the rear filter.
The brushes in the engine are placed in special shafts made of brass, as a rule, this is ordinary carbon in the form of graphite. Over time, the brushes rub against the collector roller, their middle is ground down and they become slightly semicircular, due to which the contact area with the collector pads increases. The brushes in their shafts are pressed by springs, creating the necessary pressure of the graphite, in the process, by the robots, to the collector.The brush will work until it wears off and the spring cannot properly contact the graphite with the manifold.
It is necessary to monitor the cleanliness of the collector shaft itself, clean it from carbon deposits if necessary and remove the oxide layer to a copper sheen.

The shaft is attached to the stator by two bearings of different sizes, as a rule, this is done in order to make it easier to disassemble it. The front is usually large, and the back is smaller.

The shaft is carefully knocked out of the stator using any suitable tools. Then we look at the course of the bearings, because of the dusty robots they get clogged despite the presence of anthers. If necessary, the anthers are carefully removed with a thin screwdriver or an awl, washed with a jet of WD-pulleys, after which the balls must be lubricated, for example, with grease such as Litol-24 or EP-2, after which the boot is put in place and snaps into its grooves in the bearing itself.

To start some kind of repair or maintenance of the vacuum cleaner, you need to remove the case. Each model has its own methods.
First of all, all filters that impede access to the motor are removed, the housing screws are unscrewed, including secret ones (under the buttons, for example). Having unscrewed all the screws, you need to carefully try to disassemble the case, if this fails, take a closer look where there may still be latches or additional screws, if you do not pay attention to this, you can break the case.

Then the entire electrical installation is disconnected, as a rule, the connections are made on the connectors.
The plastic motor housing is unscrewed from the bed and the motor is then removed from its plastic housing.
In some models, it is simpler and the motor itself is fixed in the body of the vacuum cleaner in special rubber grooves-seals or screwed tightly to the general body of the vacuum cleaner.

To disassemble the engine and remove the fan impeller first of all, we will remove the front part of the casing (above the impeller). We take a thin metal object, you can use a screwdriver and gently bend it off the side of the casing so that the screwdriver goes a little into the middle, then gently push the upper part of the casing out, as a result of which the entire impeller becomes available to us.

The nut on the impeller usually has a left-hand thread (but there are exceptions) We try to unscrew it by holding the impeller with our hand, if it scrolls and in this way it is impossible to unscrew the nut, there is one great way
So .. we take a good stranded wire with a cross section of more than 1.5mm in dense rubber insulation (to prevent slipping). We push in such a wiring and wrap the collector shaft 2-3 times, turn to turn and stretch it in different directions, thereby fixing the shaft motionless.

It is most convenient to do this together, one person fixes the collector with the ends of the wire stretched to the sides, and the second unscrews the nut on the fan disk.
The method is very convenient and safe for fixing the anchor. In the same way, when reassembling, tighten the nut.

After removing the fan impeller, unscrew the housing screws; by this time, the brushes should already be removed.

Then carefully pull out the anchor, twisting the upper part slightly if necessary.

If necessary, the bearings are removed using a commercially available tool or special thread pullers. In especially severe cases, the bearing sometimes “sticks” tightly to the sleeve; a special hydraulic press is used to remove the bearings.

bearings
brushes
fuse
network wire
no contact in the switch
motor winding, breakage or burnout of the winding (stator or rotor)
capacitor failure
breakdown of the electronic circuit of the power regulator

Drop in power and suction power.
The most common cause is either a clogged filter or a defective bearing.
It is necessary to clean the filter and check the operation again, also check the operation (draft) of the vacuum cleaner without filters, since it happens that the usual cleaning of the filter does not help and it already needs to be replaced.
If the draft without filters does not give the same working draft, you will have to disassemble the vacuum cleaner, the impeller on it should easily turn with your finger without much effort. Additionally, we remove and inspect the brushes and clean the collector from carbon deposits using zero sandpaper or a piece of ordinary cloth.

In some cases, the tightness of the hose is broken, this can be both a violation of the integrity of the hose itself and the connecting pipes at the ends of the hose, the hose simply slips out of them a little.

The vacuum cleaner does not turn on.
If everything is fine with the voltage in the outlet, disassemble the vacuum cleaner and first of all inspect the fuse and the power cord, especially at the very end of the cord on the winding drum in the soldering points.
If there is a tester, we call for a contact.
The power button could break or the contact is simply broken in it, it sometimes gets clogged, again, with the help of the tester, we make sure that the button is working properly.
If all the elements have been called by the tester and the voltage comes to the engine brushes without problems, and the brushes themselves are not erased, then most likely you will have to repair the engine expensively or simply replace it, since in most cases it is more expedient to install a new motor than to repair a tired old one by rewinding.

If the vacuum cleaner worked for a long time and does not turn on then it is quite possible that the protective thermostat on the engine itself has worked as a result of overheating - in this case, there is nothing to repair, it will be enough to leave the vacuum cleaner to cool the engine.

The speed of the vacuum cleaner motor is not regulated.
The most common cause of such a malfunction is the breakdown of the triac, in which the voltage through it is not regulated but freely passes through it without any control. It is possible that this element fails, and it is possible that contact is lost on one of the legs of this element on the board.
By slightly pressing down on the speed regulator knob, you can make sure whether the regulator itself is in good working order or the contact may be broken in it and the regulator slider does not contact its site.

The vacuum cleaner emits a foreign smell and hot air.
First of all, you need to make sure that the suction inlet is not clogged, inspect the hose, check the retraction force at the inlet and whether the sound of the engine changes when you plug the inlet with your palm. In case of satisfactory operation on the part of the suction system, we can assume that the engine is malfunctioning, but most likely the brushes.

The vacuum cleaner hums and rumbles - the reason for this action is the engine, and in particular its bearings. Most likely they need additional lubrication or, if there is a large shaft around their axis, they need to be replaced with new ones.

The cord does not tighten when the button is pressed or is constantly tightened during operation - malfunction of the winding drum, perhaps the spring has burst, is weakened or, on the contrary, is too tight.
We inspect the pressure roller of the button and, if necessary, having removed the drum, we wind up or unwind the wire on the drum - changing the tension of the drum itself to the one we need.

As a rule, it is not complicated and is quite standard in most models.
