Why did the LG vacuum cleaner start making noise? 
Automatic translate
Household appliances manufactured under the LG brand are distinguished by their reliability, functionality and long service life. This also applies to vacuum cleaners from this Korean manufacturer, which are popular all over the world. But intensive or careless use, regular voltage surges and other negative factors sometimes lead to their breakdown. In this case, it is necessary to repair the LG vacuum cleaner , and you can handle simple cases yourself, but in case of complex problems, it makes sense to contact a service center. One of the common problems is increased noise during operation of the vacuum cleaner. To eliminate it, you need to identify the causes, and then begin to repair this household appliance.
Causes and consequences of increased noise during operation
If during operation the noise level of the device increases noticeably, it is necessary to identify the causes of this phenomenon. When working with carpet, especially long-pile carpet, the volume will increase and this is absolutely normal. But if the noise increases regardless of what kind of coating the vacuum cleaner is working with, then this may be due to the following reasons:
- One of the most common causes of noise is an overfilled dust bin. In standard models, filling this compartment is allowed no more than 80%. Many of them have an indicator indicating that it is time to clean the dust container. At the same time, the suction capacity decreases and the engine heats up.
- Modern models of LG vacuum cleaners are equipped with special filters that trap fine debris. This increases their efficiency, but over time they become clogged, which leads to a steady increase in noise when operating in all modes.
- During operation, objects may fall into the tube and block its lumen. At the same time, smaller debris is layered on top of such a blockage, which aggravates the situation.
- Bearing failure can be the result of a manufacturing defect, which happens very rarely; much more often, it is a consequence of untimely cleaning of the filters. If dust passes through them, it will inevitably settle on the bearings. This increases friction inside the unit, which begins to require more power to operate. Sometimes the process is accompanied by a characteristic buzzing or whistling sound.
- Sometimes the cause of loud operation is problems with the electric motor. The appearance of problems with the winding and other structural elements can lead to a characteristic roar during operation. As a rule, such a breakdown is associated with voltage surges, moisture and dust entering the engine.
An increase in noise during operation indicates that the engine is running at higher speeds under load. This leads to faster wear of all its elements, overheating of the winding and its possible failure. Even modern protection systems are not able to completely resist accelerated wear, and after they are activated, you will need to wait for the engine to cool down. After turning it on again, it overheats again and the vacuum cleaner turns off, so it becomes extremely inconvenient to work with it. Therefore, if noise increases, you need to immediately eliminate the problem so as not to worsen the situation.
What to do if there is an increase in noise when operating an LG vacuum cleaner?
If the volume of the engine increases while the LG vacuum cleaner is running and there are no other signs of failure of components and components, you can fix the problem yourself. First, it is recommended to check the tubes and hoses by simply blowing them out. If there is a blockage, this can be immediately detected, after which cleaning should be carried out. It is recommended to additionally inspect the brush, on which the bristles may become tangled, wool or hair may accumulate.
If the tubes are clean, you need to check the waste container or bag. At the same time, a reusable bag can be carefully washed, and a disposable bag can be replaced. Some users try to clean disposable dust bags and reuse them. This should not be done, because with prolonged use they may rupture, and all the dust will be directed into the mechanisms of the vacuum cleaner.
Vacuum cleaners equipped with filters require additional maintenance. In order not to overload the engine, it is recommended to change or clean this element after 6-7 cleanings, depending on what type is installed on the household appliance. At the same time, it is advisable to clean the internal elements of the vacuum cleaner if dust settles on them.
If these procedures do not reduce the noise intensity, the cause is likely in the bearings or the motor. It is impossible to repair these components without professional training and equipment. In this case, it is better to contact a service center, where a specialist will deal with the problem, repair or replace the problematic components.
