Household appliances break down over time as a result of wear and tear or improper handling. If the vacuum cleaner does not turn on, then a problem arises with cleaning; it is difficult to keep the apartment clean without such an assistant. In such a situation, there is a need to quickly resolve the issue of troubleshooting.
You can get rid of the problem in the following ways: take the vacuum cleaner to the nearest service center and try to deal with it yourself.
The vacuum cleaner may turn off during operation, have poor suction, buzz loudly, or not turn on. It is necessary to understand the cause of the equipment malfunction and, if possible, eliminate it. This will require patience, simple electrical appliances and tools. The complexity of the repair depends on the type of fault. First you need to find out the reason why the vacuum cleaner does not turn on. In most cases, the task can be completed without outside help. To do this, you need to carefully inspect the vacuum cleaner for visible damage. And if they are missing, disassemble the body and diagnose the parts.
Why doesn't the vacuum cleaner work?
Vacuum cleaners differ in design, power, and manufacturer. The main part of the device is an electric motor; it creates a vacuum, which leads to the absorption of dust. Different models use different types of filters and dust bags, which must be kept clean. But the principle of operation of the products is similar, so identifying the causes of failure is carried out according to the same scheme.
Before starting work, turn off the vacuum cleaner, this will help avoid electrical injuries.
It is necessary to find out the cause of the breakdown in order to decide on further actions. To do this, you need to remove the case; each model has its own characteristics. Before removing the filters, unscrew the housing screws. Then you need to carefully inspect the device for the presence of hidden fasteners, otherwise when removing the part you can break it.
The device may not work for the following reasons:
- Faulty socket.
- The cord is damaged or kinked.
- The problem is the plug.
- The power button does not work.
- The thermal protection of the electric motor is disabled.
- The motor is broken.
Often the main cause of device malfunction is engine overheating. This problem in most cases occurs on hot summer days, when the device is used for a long time. The vacuum cleaner is disassembled in the off state, the motor is found and then the device is plugged in.
If the engine sparks, this is possible for the following reasons: wear of the graphite brushes, a short circuit in the armature winding, or the load on the engine is exceeded. In such a situation, the filters could become clogged and need to be cleaned, or the bearings could wear out and need to be replaced. If a short circuit occurs due to overheating, the motor may burn out. In this case, it cannot be repaired; only replacement is possible.
What to do
To understand the cause of the breakdown, it is necessary to analyze possible problems. This work is not difficult, it can be done at home yourself.
Clogged filters
There are several categories of filters, so each type has its own nuances. Cleaning filters:
- filter bag - emptied or changed as it fills;
- cyclone filters - washed with cold water after each cleaning;
- water - disassembled and washed under the tap;
- fine filters - disposable ones are blown with air, reusable ones are washed.
Hose clogged
If during operation the vacuum cleaner suddenly stops sucking in dust, you need to check the flexible hose for stuck objects.
You can get rid of them in several ways:
- The hose is disconnected from the device and accumulated dust and foreign objects are removed with long tongs.
- If an object is stuck in the middle of the hose, then you need to use a thin wire.
- You can also clean the hose under a strong stream of water.
Diagnosis and Troubleshooting
Check the functionality of the outlet by connecting other household appliances to it or connecting the vacuum cleaner to another source. It is possible to use indicators showing the voltage in the electrical network. Another way to check is to use a voltage detector. The power connection cord is movable, so during operation kinks occur, contact is lost and the device stops turning on. Carry out a thorough inspection of the cord, especially the place where it enters the vacuum cleaner and the plug for mechanical damage and kinks. If defects are found, it must be replaced.
If visual damage cannot be found, you will have to disassemble the device. After opening the vacuum cleaner body, remove the panel with the power and cable rewind buttons. It is necessary to inspect the cable to the point where it is connected to the control board. We plug the device into the outlet and check for voltage at the connection points. If it is absent, the cable is checked for kinks and damage. The damaged cord is removed from the housing, a new one is soldered to the contacts, you must ensure that it passes through the hole in the cover. All elements of the device are put in place, all that remains is to check the operation of the device.
If no faults are found, then after disconnecting the device from the network, disconnect the plug. You need to unscrew the screws and inspect it inside if it is disassembled. In many models it has a monolithic structure and is checked for external damage. If the part cannot be disassembled, a knife will do; check the cord and plug for voltage using a special device.
The faulty part should be found or the broken contact in the plug should be corrected. The part must be separated from the cord, the cable sheath removed, the wires disconnected and the insulation removed. Then the wires are stripped, a connection is made, and the ends of the wire are twisted. After a simple procedure, the plug must be carefully connected to the cord. After the work has been done, the electrical appliance is turned on to check its functionality.
The power button often breaks at the contact point. To repair it, you need a soldering iron, which can be used to desolder the part and install a new one. If you cannot purchase such a spare part, you can try to repair it yourself. The contact may be broken, or it may simply be clogged. If the button turns out to be working, then look for a triac on the board. The device is connected to the network and the voltage at the output to the engine is measured; if there is no voltage, the part should be replaced.
Call the master
When attempts to independently solve the problem of a Samsung vacuum cleaner not turning on are unsuccessful (even if there is no visible damage, the household appliance still does not work), a professional technician will come to the rescue.
A faulty vacuum cleaner can be taken to the nearest service center, or you can call a specialist at home (contacts are not difficult to find on the Internet). When filling out an application, you must indicate the model of the Samsung vacuum cleaner (information can be found in the device’s passport or on a plate located on the case), and clearly describe the problem that has arisen.
Depending on what exactly caused the vacuum cleaner to not turn on (the exact reason is determined by the technician after diagnostics), repairs can cost from 400 rubles. up to 1500 rub . Additionally, the cost of replaced parts and assemblies will be charged.
Full payment is made only upon completion of repair work, followed by testing of the household appliance. Any demands for full prepayment for repairs that have not yet been completed is a reason to refuse the services of a master!
Checking the serviceability of the electric motor
If there is voltage at the output of the triac, the reason is in the motor. But before drawing such a conclusion, check the thermoregulation relay. It is responsible for protecting the engine from overheating. When the device operates for a long time, the housing heats up, which leads to the device turning off. To fix this problem, just let the engine cool down. After this, the vacuum cleaner will work again.
If the reason is not in the relay, then check the brushes. When worn, the chain between the winding and the rotor disappears. The parts must fit tightly to the rotor and have some margin along the way. Over time, the brushes grind in, the core wears off, which leads to an increase in the area of contact with the commutator. They work until they wear off.
In some cases, to restore the functionality of the mechanism, it is enough to replace the brushes. You can complete the task yourself. Next, the stator circuit, rotor, and brushes are checked. If everything is fine with it, then the reason may be in the rotor winding. This is an expensive part.
The fact that the electric motor has burned out is indicated by the appearance of a burning smell. If there is no smell, then there is a chance to fix the breakdown without buying a new motor. The engine cannot be disassembled, so the wire connections are checked through the holes in the housing. Check the connection points of the windings to the terminals and brushes. During intensive use, the product experiences constant vibrations, the wire may break and the circuit will be open.
Various types of electric motors
Various electric motors are used in technology. And the choice of diagnostic method depends on the type of engine. Examples include the following electric motors:
- vacuum cleaner motor: asynchronous (two phases - alternating current) capacitor;
- screwdriver motor, angle grinder, etc. – collector (alternating current).
In the first case, diagnostics are quite simple. As a rule, these motors have only two windings. Therefore, in order to check the correct functioning of the engine, it will have to be disassembled.
We test the coils using an ohmmeter (switch the multimeter to the required mode). The resistance of the working winding should be 50% less than that of the starting winding. Be sure to test the coils for breakdown on the body. This resistance must be very large.
How to prevent vacuum cleaner breakdown?
Modern technology has protection that controls the operating parameters of the device. Automation can turn off the operation of the device for the following reasons:
- Filling a garbage bag. This is evidenced by the appearance of the smell of dust, which enters the room through the holes in the mechanism body.
- If a large object hits the air duct.
- The hose is clogged. In this case, you may notice a change in sound when the engine is running.
- The motor protection filter is dirty. A specific smell of burnt dust appears.
To fix such problems, you don’t need to call a technician; just unplug the device and clean it of any debris accumulated inside. A completely filled garbage bag must be replaced or cleaned; it is not recommended to turn on the device without a dust collector. The vacuum cleaner is disconnected from the network, the cover is removed to provide access to the container. If your model does not have a self-closing neck valve, close the neck and then remove the bag. It is replaced with a new dust collector or cleaned of dirt, then it is installed in place. When installing the bag, make sure that the neck fits well to the bag holder. If this is not done, the motor may overheat.
The instructions indicate how many filters the model has; they must be periodically checked and cleaned of debris. Before this operation, the device is disconnected from the power supply, the filter is removed and cleaned; in some models this element can be washed. It must be dry before installation. The filter is replaced in accordance with the manufacturer's recommendations. The hose is checked after it is disconnected from the device. If a blockage is found, it is removed. To do this, remove the nozzle and straighten the hose, then connect it to the device and turn on the vacuum cleaner. If the air duct is clogged, disconnect the pipe and remove debris, if any, there.
The bulk of all device breakdowns occur as a result of motor overheating. Do not overload the mechanism or operate it continuously for more than 40 minutes. After working for 20 minutes, the device requires rest, which eliminates the possibility of overheating. If the model uses a dust bag, it must be cleaned in a timely manner. When it is filled to 100%, air does not flow freely, which creates additional conditions for overheating. In cyclone-type models, you should monitor the cleanliness of the plastic container (read more about maintenance procedures - an eternal vacuum cleaner, or rules for caring for household appliances).
Inspecting the components
- During cleaning, a large object was pulled in and got stuck inside the hose or telescopic handle;
- the dust collector has not been cleaned for a long time and is completely clogged with debris;
- the filter on the exhaust of the vacuum cleaner is clogged;
- The corrugated hose, working nozzle or telescopic handle is damaged.

Results and recommendations
Read the instructions for use of the device carefully, this will help you avoid problems with its operation. Strictly adhere to the instructions specified by the manufacturer to prevent problems with the operation of the device. When equipment breaks down, a person is faced with a dilemma: to sort it out on his own or immediately contact a service center. To repair a vacuum cleaner yourself, you may need simple skills in handling electrical appliances and the most basic knowledge of electrical engineering. The choice always remains with the consumer: disassemble the device at your own peril and risk or seek help from specialists. If there are fears that attempts to eliminate the malfunction will lead to permanent breakdown of the equipment, then it is better not to take risks.
A vacuum cleaner is a fairly simple device, and in many cases you can repair it yourself. The only exception is a short circuit inside the electric motor. It will not be possible to eliminate damage by rewinding the windings due to the non-separable motor housing. In this case, you will have to change the entire electric motor, which is not cheap.
If you are not sure that you can cope with the task of identifying and repairing a vacuum cleaner, then it is better to contact professionals.
They will be able to quickly cope with the task and restore the functionality of the device.
Hose design features
Most corrugated hoses for cleaning equipment are a tube made of elastic material (polypropylene).
The tube is usually no more than 1.5 meters long. Thanks to the corrugated surface, the accessory has the ability to stretch within small limits.
Classic design of the working hose of the vacuum cleaner. Two movable pipes are connected to each other by a corrugated elastic tube. This design makes it easy to manipulate the accessory when cleaning.
One end of the flexible conduit ends in a short piece of rigid plastic tubing. This part is a connection link with the extension rod or directly with the working nozzle of the vacuum cleaner.
The opposite end of the hose is equipped with a short locking pipe, through which a locking connection is formed with the vacuum cleaner module. This lock pipe is actually also a continuation of the corrugated tube.
Traditional break points for vacuum cleaner hoses are the area where the corrugated hose meets the process end. Cracks or tears form due to increased load on this area during the cleaning process
The practice of using vacuum cleaners notes that it is along the junction lines of the elastic corrugation with the end rigid elements that most often a rupture occurs, and a breakage of the hose is considered one of the most common breakdowns of a vacuum cleaner.
Meanwhile, the formation of even a small rupture in the hose leads to a significant loss of efficiency of harvesting equipment.
Reason #4: Software glitch
It's no secret that modern mobile phones are controlled by software specially created for them. The software of today's cellular device is as complex as Windows, Mac OS or Linux computer systems. Therefore, we can assume that the phone cannot be started due to some damage to the software part of the device. It is worth noting that the previously existing problem “Samsung phone does not turn on” was relatively easy to fix. With the help of a service cable and a program freely distributed on the Internet, everything was resolved within a few minutes. Now, reprogramming phone software is an incredibly difficult task. Since a generally accepted update is nothing compared to flashing the program code of a modern mobile communication device. By the way, not every cell phone repairman is a specialist who can restore the functionality of the phone’s software components.
Tip #4
Diagnosing the “collapse” of a mobile system is elementary. As a rule, a phone with damaged software will boot only until the company logo appears. Then the device may go into a “stupor” or “freeze”. Most often, an unsuccessful cyclic reboot occurs. Less often - absolute inaction. Paradoxical as it may seem (after all, we all know about the excellent Japanese quality), nevertheless, the situation “Sony phone does not turn on” is a fairly common occurrence in the world of “software failure”.
Security measures
Electric shock is the main danger for the user of the device. Errors in compliance with safety rules are not acceptable.
The main thing: when cleaning a room, the device should be carried on a handle designed specifically for transportation. Also, the insulation of the connecting wire should not have any damage to the sheath.
When cleaning the garbage container, household appliances must be unplugged.
The safety instructions prohibit repairing the vacuum cleaner yourself. However, if the person operating the vacuum cleaner has sufficient skills, you can repair it yourself. The main thing is to carry out work on a completely de-energized device.
Testing commutator motors
Here things are a little different. You need to start with pairwise testing of the collector lamellas. Moreover, the resulting indicators should be almost equal to each other.
We also test for breakdown on the hull - we place one probe on the anchor, the other on the hull. Resistance values in such measurements should tend to infinity (very high resistance).
Pay attention to the integrity of the stator winding. Place one probe on the stator surface and the other on the winding terminal.
High resistance values are also advantageous here.

Repairing the washing machine power supply
Geographically, the power supply of the washing machine is located on the electronic board of the device. You can determine it by the presence of one or two transformers. As shown above, the power switch is sometimes integrated with the pulse generator, and sometimes there is protection inside. Therefore, for the structural division of the board, it is useful to find descriptions for all relevant microcircuits.
At times, the power supply is represented by a separate miniature PCB plate, in the manner of an expansion card for the motherboard of a personal computer, inserted into a slot perpendicular to the electronic brain of the washing machine. But the main thing is that the power bus should go to this place. 230 volts can go to various relays (sometimes located nearby) that power the sump pump, intake valve. As needed, the programmer (on-board computer, electronics unit - call it what you want) gives a signal to use the selected equipment.
Software problem
When malicious applications are active, there is no anti-virus cleaning, no cleaning of software junk (cache), or installation of a large number of applications from little-known and unreliable manufacturers, the Android operating system often crashes.
There are several options to solve this problem:
- reset the system to factory settings;
- flashing.
Remove the SIM card and flash drive and get started. You must get to the Recovery menu for a hard reboot or factory reset. To do this, hold the volume control “up” and the power button for a long time.
If there is no reaction, then contact a specialist for flashing. You can change the firmware yourself, just use the software product from the official website of the manufacturer Samsung.
Reasons for software failure
Modern TVs have a very large number of settings, which are quite difficult to understand. Therefore, a problem often arises due to incorrect settings by the user, after which the device may begin to turn on and off spontaneously.
One of the popular problems can also be automatic software updates: the received Internet update can independently change the TV settings.
If such a failure does occur, it is quite easy to fix it. You need to go to the settings and uncheck the box next to the self-shutdown section.
Alternatively, you can turn off automatic software updates.
If all these methods do not help, you need to look for failures elsewhere.
