Why does not the vacuum cleaner turn on

Household appliances over time fails as a result of wear and tear of parts or improper handling. If the vacuum cleaner does not turn on, then there is a problem with cleaning, it is difficult to maintain cleanliness in the apartment 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, try to cope with it yourself.

Vacuum cleaner can shut off when working, poorly absorb, buzz loudly, do not turn on. It is necessary to understand the cause of the malfunction of the equipment 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 managed without assistance.To do this, you must carefully inspect the vacuum cleaner for visible damage. And in case of their absence disassemble the body and to diagnose the details.

Why doesn't the vacuum cleaner work?

Vacuum cleaners differ in design, power, 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 that should be kept clean. But the principle of operation of products is similar, therefore, the identification of the causes of failure is carried out according to one scheme.

Before starting work, turn off the vacuum cleaner, it will help to avoid getting electrocution.

It is necessary to find out the cause of the breakdown in order to decide on further actions. This requires removing 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 you can break it when removing the part.

The device may not work for the following reasons:

1. Faulty outlet.
2. There is damage or bending of the cord.
3. The problem is in the plug.
4. The power button does not work.
5. Motor thermal protection is disabled.
6. Broken motor.

Often the main cause of a device malfunction is overheating of the engine. Such a 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 appliance is turned on.

If the engine sparks, then this is possible for the following reasons: wear graphite brushes, short in armature winding, motor load exceeded. In such a situation, the filters that are necessary could be clogged. to clean, or there was a wear of the bearings, they need to be changed. If a short circuit occurs as a result of overheating, the motor may burn out. In this case, it is beyond repair, only its replacement is possible.

Diagnose and troubleshoot

They check the working capacity of the outlet by connecting other household appliances to it or connecting a vacuum cleaner to another source.You can use indicators that show the voltage in the power supply. Another way to check is to use a device that determines the voltage. The power supply cord is mobile, so there is a break in operation, the contact disappears and the device stops turning on. A thorough inspection of the cord is carried out, especially the places where it enters the vacuum cleaner and the plug for mechanical damage and kinks. If defects are found, it must be replaced.

If visual breakdowns could not be found, it is necessary to disassemble the device. After opening the case of the vacuum cleaner, we remove the panel with the buttons for turning on and winding the cable. It is required to inspect the cable to the place of its connection to the control board. Turn on the device in the outlet and check the presence of voltage at the connection points. In case of its absence, the cable is checked for breaks and damage. The damaged cord is removed from the case, a new one is soldered to the contacts, it must be ensured that it passes through the hole in the cover. All elements of the device are put in place, it remains only to check the operation of the device.

If no malfunctions are detected, then after disconnecting the device from the mains we separate the plug.It is necessary to unscrew the screws and inspect it inside, if she understands. In many models, it has a monolithic structure, it is checked for external damage. If the item does not understand, the knife will fit, check the cord and plug for the presence of voltage using a special device.

The faulty part should be found or fixed broken contact in the plug. The part must be separated from the cord, remove the cable sheath, disconnect the wires and remove the insulation. Then the wires are stripped, the connection is made, and the ends of the wire are twisted. After a simple procedure, the plug must be carefully attached to the cord. After the work done, the appliance switches on to check its operation.

The power button often breaks in the place of contact. To repair it, you need a soldering iron, through which the part is soldered and a new one is installed. If it is not possible to purchase such a spare part, you can try to repair it yourself. The contact can be broken in it, or it just gets clogged. If the button is working properly, then a triac is searched for on the board. The device is plugged in and measured at the output voltage to the engine,in the absence of voltage, the part should be replaced.

Motor check

If the voltage at the output of the triac is, the reason for the motor. But before making such a conclusion, check the thermoregulation relay. It is responsible for protecting the engine from overheating. With long-term operation of the device, the case heats up, which leads to the device turning off. To eliminate this malfunction, it is enough to cool the motor. After that, the vacuum cleaner will work again.

If the cause is not in the relay, then check the brushes. When worn, the chain between the winding and the rotor disappears. Details must fit snugly to the rotor and have some margin along the way. The brushes grind over time, the core is ground off, which leads to an increase in the area of ​​contact with the collector. They work until they are erased.

In some cases it is enough to replace the brushes to restore the working capacity of the mechanism. You can complete the task yourself. Next is the verification of the stator circuit, rotor, brushes. If everything is all right with it, the reason may be in the rotor winding. This is an expensive item.

The fact that a motor has burned out is indicated by the appearance of a burning smell. If there is no smell, then there is a chance to eliminate the damage without buying a new motor. The engine is not disassembled, therefore the points of connection of the wires are checked through the holes in the housing. Check the connection points of the windings to the terminals and the brushes. With intensive use, the product experiences constant vibrations, the wire may break and the circuit will be open.

Try to tighten the wire and fasten it. If you can not do this, add another piece of a few centimeters. This is quite difficult to do, it is necessary to solder through a small hole. But it is possible to complete the task, as a result of which the device will work again. It is much cheaper than buying a new motor, which is the most expensive part of the device. If the product has already served its time, then replacing the engine is unprofitable, it is better to purchase a new vacuum cleaner.

How to prevent breakage of the vacuum cleaner?

In modern technology, there is protection that controls the parameters of the device.Automation can disable the operation of the device for such reasons:

1. Filling the trash bag. This is evidenced by the appearance of the smell of dust, which through the holes in the case of the mechanism enters the room.
2. In contact with a large object that blocked the duct.
3. Hose clogged. In this case, you can notice a change in sound when the engine is running.
4. Contamination of motor protection filter. There is a peculiar smell of burning dust.

To eliminate such problems, you do not need to call the wizard, it is enough to disconnect the device from the network and clean it from debris accumulated inside. A completely filled bag with garbage 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 the model does not have a self-closing throat valve, it should be covered and then removed. It is replaced by 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, motor overheating may occur.

The instructions indicate how many filters the model has, they should be periodically checked and cleaned of garbage. Before this operation, the device is disconnected from the mains, the filter is removed and cleaned, in some models this element can be washed. It must be dried before installation. Replace the filter in accordance with the manufacturer's recommendations. Check the hose 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 with the device and turn on the vacuum cleaner. When the duct is clogged, disconnect the pipe and remove the debris if it is there.

The bulk of all damage to the device occurs as a result of overheating of the motor. You should not overload the mechanism, operate it continuously for more than 40 minutes. After working for 20 minutes, the device requires rest, which eliminates the possibility of overheating. If a dust bag is used in the model, it should be cleaned in a timely manner. When it is filled to 100%, the air does not pass freely, which creates additional conditions for overheating. In cyclone-type models, the purity of the plastic container should be monitored (for more details on the maintenance procedures -eternal vacuum cleaner, or the rules of care for household appliances).

Results and recommendations

Carefully read the instructions for use of the device, this will avoid problems with its operation. Strictly adhere to the rules specified by the manufacturer to prevent problems in the operation of the device. When a vehicle breaks down, there is a dilemma in front of a person who can figure it out on his own or contact the service immediately. To repair the vacuum cleaner yourself, you may need simple skills in handling electrical appliances, the simplest knowledge of electrical engineering. The choice is always up to the consumer, disassemble the device at your own risk and risk or seek help from specialists. If there are fears that attempts to eliminate the malfunction will lead to the final breakdown of equipment, it is better not to risk it.

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 motor. Repairing winding damage will not be possible due to a non-separable motor casing. In this case, you will have to change the entire electric motor, which is not cheap.

If you are not sure that you will be able to cope with the task of identifying and eliminating the breakdown of a vacuum cleaner, then it is better to turn to professionals.

They will be able to quickly cope with the task and restore the working capacity of the device.
