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. 1. Unscrew the fixing screws from the device case using a Phillips screwdriver.
  2. 2. Then you can remove the cover of the vacuum cleaner.
  3. 3. Having disconnected the wires from the control board, you need to separate the device case.
  4. 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. 1. Use a thin screwdriver to remove the impeller cover. The nut usually has a left-hand thread.
  2. 2. After that, unscrew the fastening nut.
  3. 3. Then it is required to remove the brushes and unscrew the tightening screws of the device case.
  4. 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

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

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.
