Why does the vacuum cleaner heat up: what to do if it overheats and turns off

The vacuum cleaner gets very hot during operation

A one-time overheating of the device leads to the fuse turning on and a complete shutdown, but if the situation is constantly repeated, the load on the engine increases, and as a result the motor breaks down. Overheating is accompanied by strong noise or a sudden buzzing sound, loss of power and suction, and the exhaust air also becomes hot.

In order not to permanently break the equipment, it is necessary to carry out a home inspection at the first sign of a malfunction.

What to do if the suction power drops or turns off altogether

Due to a drop in suction power, the device begins to leave debris, weakly adheres to carpets, quickly heats up and begins to go out, and soon may turn off completely.

First you need to exclude external causes: check if the settings have changed, how hot it is in the room, what kind of garbage is being removed.
Attention! Do not use the device for work not intended for it, for example, collecting construction waste. Household models are too weak, construction waste is smaller than usual and will quickly break the equipment.

If the vacuum cleaner does not suck up dust

The reasons for poor absorption of debris and dust may be the same as for overheating. To identify the problem, you should perform the following steps step by step:

First, be sure to disconnect the device from the network;
Next, a general inspection of the device is carried out;
It is worth making sure that the selected mode is correct - perhaps the parameters are simply wrong;
If all this does not help, then you should disassemble the unit: disconnect the pipe and brushes, then remove the body and inspect the insides (dust bag or container, filters, engine).

If a malfunction is detected, you should begin to eliminate it.

The bag is overflowing

A common reason for weak vacuum cleaner traction can be an overfilled dust and debris bag: some older models do not have a fullness indicator, so you should regularly check the bag's fullness level yourself. When the dust container is 70% full, the suction power may decrease significantly or disappear altogether.

During the emptying process, it is necessary to examine the material from which the bag is made:

paper bags are disposable, so they can only be replaced with a new one;
fabric bags can be washed in plain water and put back in place after drying.

If everything is in order with the dust collector, but the draft still does not appear, then you can proceed to the next stage.

The filter is clogged

If the vacuum cleaner does not suck, it may be due to the filters. Any model contains 2 filters, one of which is used for fine cleaning, and the second is exhaust. If the exhaust filter has never been replaced, it should be done now; it should be changed every 50 hours of operation. The fine filter should be cleaned or changed regularly: you can wash it with warm water and then dry it thoroughly. Filters are usually located near the back of the device.

Dirt in the hose or brush

A drop in suction power sometimes occurs due to a damaged hose or nozzle. First, you should carefully inspect the suction pipe and inspect the place where it is connected to the body - the pipe may not be fully seated or not fit tightly. If there are blockages in the pipe, it is necessary to clear them with wire. Next, you need to check the hose for damage: to do this, you can disconnect it from the device and put your hand on the inlet. If the traction is good, then the reason lies in the hose.

You should also study the nozzle; sometimes it can cause poor performance of the device. It is necessary to clean the brushes from threads, hair and other debris, and also check for permeability inside. The bearings should also be checked for proper operation, because the force of the air flow depends on them.

Damage to the device

To gain access to the main part of the vacuum cleaner, remove the housing protection. Usually this unit stops functioning due to a blown fuse - you can check it with a multimeter. If the fuse is faulty, select one with similar parameters and install it in place. If the contact is broken, this can also cause a malfunction; solder the damaged contact in place with a soldering iron. If there is a suspicion that the motor brushes are malfunctioning, then you should work extremely carefully; an incorrect connection can lead to the device starting to work in the other direction and simply blowing out dust. If the winding on the coil breaks, you should prepare to replace the unit or buy a new vacuum cleaner.

Each model has its own weaknesses. In LG models, graphite brushes begin to become unusable after prolonged use, and in Samsung devices, sometimes there are winding insulation failures, which ultimately leads to an interturn short circuit.

Important! A faulty engine is practically impossible to repair on your own and will require the help of competent specialists to restore it.

How to understand what is causing the heating

There are several reasons why a vacuum cleaner gets very hot. This is a malfunction in the engine, a dust bag filled to capacity, a clogged filter, or debris stuck in the hose. Some of them you can detect and fix yourself, while others will require you to contact a service center.

How to diagnose problems

It is recommended to look for the reason why the vacuum cleaner may heat up during operation using the method of elimination. It is necessary to remove the parts one by one or turn them off, then check the operation of the equipment without them. You can only remove parts when you disconnect the device from the network.

First of all, you need to check the installed settings. Perhaps they got lost, which is why the equipment began to work at a higher speed and heat up more.

The home diagnostic procedure should be as follows:

You need to disconnect the hose and nozzle, then turn on the equipment. If the problem goes away, there is probably a small object stuck in the hose that is blocking the flow of air.
It is worth inspecting the inlet: it may be clogged with dirt or covered by something pulled in during cleaning.
Then you need to check the dust collector: pull it out and turn on the device. If the work goes smoothly, you need to clean the bag or container.
You should check the filter in the same way: remove it after turning off the equipment and rinse it.

If all else fails and the vacuum cleaner continues to heat up, most likely the reason is the motor. In order not to damage the equipment, it is better not to try to repair it yourself, but to take it to a service center for diagnostics.

What causes the suction power to drop?

The reasons why suction power disappears are the same as due to heating. There are expensive models and budget ones. Poor oxygen flow is the first signal that there is a problem. A complete diagnosis will allow you to find out the exact cause of the device malfunction. Before doing this, be sure to disconnect the device from the network, then inspect it and check the modes.

If this is not the reason why the vacuum cleaner heats up and stops working well, then you need to disassemble the device. Take an old dust collector and detach the brush and pipe from it. Next, remove the housing and inspect the insides, for example, the dust collector, filter, engine and other parts.

Note! If the breakdown has not been detected, you can begin to fix it.

Checking the dust container

First, you need to check the dust collector to answer the question why the vacuum cleaner turns off during operation. Old models do not have special indicators, thanks to which you can see the fullness. For this reason, you need to check this yourself. Absorption is lost due to filling. When cleaning, you need to look at the material the garbage bag was made from. If it is made of paper, then you need to change the bag, and if it is made of fabric, then simply shake it out and wash it. These fabric bags are reusable.

Checking filters

Next, you should pay attention to the filters, continuing to study why the Samsung vacuum cleaner gets hot. They come in thin and prom styles. If the second one has not been replaced, then this should be done. The change must occur after 50 hours. The first filter should be replaced or cleaned when dirty. To do this you need to use warm water and drying. The filter should be located before the motor on the back of the panel.

Checking brushes, hoses and other components

The suction power of the device decreases due to damage to the brush, hose and other components. First, it’s worth looking at the intake pipe, namely its connection with part of the housing. The intake pipe may not fit sufficiently. If there are blockages, they must be removed using wire. They may cause noise during operation. Next you need to check the hose for microcracks. If the pipe is damaged, you can tell by the air escaping from it when the vacuum cleaner is running. If the suction returns after replacing the pipe, then the failure was in the hose.

Sometimes the reason for the lack of suction and why the vacuum cleaner overheats and turns off is due to the convenience of the nozzle and its maneuverability.

Note! It is not uncommon for the brush to become clogged with threads, wool or hair and this prevents debris from entering the unit. If everything is in order, then the problem is the bearings. If they are also working properly, then the reason is in the motor and propulsion system.

Main causes and their elimination

There may be several reasons why a vacuum cleaner overheats and turns off regularly. Some of them, such as a stuck object or an overfilled dust bin, can be resolved yourself. Others can only be diagnosed and corrected by a specialist.

The filter is clogged

This is one of the most common reasons why a vacuum cleaner gets hot. Modern models are equipped with special filters through which air passes. Filters trap dust, dirt, debris and other small objects. Over time, the filter cells become clogged, air passes through with difficulty, and overheating occurs.

Typically there are two filters in technology:

High school graduation. Designed to retain dust and dirt, that is, the main work “lies” on it. It is recommended to clean it after 50 hours of use. If it has never been cleaned after many years of operation, a complete replacement may be required.
Fine cleaning. It traps the tiniest particles, microorganisms and allergens, usually located on the rear panel in front of the motor. It is changed when it gets dirty.

It happens that the vacuum cleaner turns off during operation, the reason lies in the filters. To make sure of this, you need to:

Turn off the equipment and remove the filters.
Turn on the device.
If it pulls well without any problems, then it’s time to wash or replace the filters.

Important! You cannot vacuum without filters: dust will pass through the device and fly back into the room, where it will get into the motor.

Obstruction in the air duct

The reason for overheating of the electric motor on a vacuum cleaner from Samsung and other companies may be the accidental suction of a small object. The latter may get stuck in the hose or inlet and interfere with the passage of air.

Note! Sometimes the problem can be identified by a strange noise from equipment that was not there before - an object hits the walls or creates resistance to air flow.

It's easy to fix the problem:

You need to turn off the device.
Remove the hose and blow it out or clean it using a long object (wire, ruler, mop handle). You can connect it to the outlet and turn it on at full power so that the air flow knocks out the excess object.

Another possible problem is a hole in the hose through which air escapes. You can find it by turning on the vacuum cleaner and carefully feeling the air duct. It is best to replace the hose.

Dust container overflowing

Sometimes finding out why the vacuum cleaner heats up and turns off, what is the reason and how to solve the problem is even easier - just check if the dust container is full. To make sure that the vacuum cleaner overheated and turned off because of this, you need to remove the dust container and turn it on. If the traction returns, then the problem has been found.

Cleaning depends on the type of container:

The container dust collector must be shaken out and washed.
Replace the disposable bag, wash the reusable one.

Attention! Some models have an automatic system that notifies you when the dust container is full, but it does not always work correctly and may show less.

Manufacturers usually indicate in the instructions how often cleaning or replacement is required. On average, the dust collector should be filled no more than 80% or replaced after 3-5 cleanings.

Hell of a reboot! How to fix your constantly overheating vacuum cleaner yourself.

Are you tired of constant breakdowns and repairs of your household appliances? Maybe you trust your equipment to the wrong specialist? It's time to take matters into your own hands, read these instructions and put an end to this issue once and for all!

Today we will look at one of the most common problems with household appliances - constant overheating of the vacuum cleaner motor and its excessive shutdown.

Causes of breakdowns and self-repair

There can be many reasons why vacuum cleaners of different models heat up and turn off. Some of them talk about the need for repairs, replacement of parts, while others talk about simple cleaning. We’ll try to figure out what your vacuum cleaner “tells” you and which spare part is faulty in this article.

Frequent reasons for the vacuum cleaner to turn off spontaneously:

One of the filters is clogged. We noted above that the problem can be solved by cleaning, which should be done regularly;
The room where you vacuum is too hot;
The hose or inlet is clogged;
Dirt has entered the motor or board;
The contact in the motor or socket is broken;
Its brush assembly is worn out.

Some points can be corrected literally on the go: ventilate the room, clean the filter and connect the vacuum cleaner to a different outlet. All this will eliminate technical damage. If such manipulations do not help, then the matter is more serious.

In practice, before the vacuum cleaner turns off, overheating usually occurs. The increase in the temperature of the unit also has its own reasons.

Why does the vacuum cleaner get hot?

In general, many problems with vacuum cleaners are associated with clogging or contamination of individual parts. This is understandable, because the device deals with dust, animal hair, and small (and not so small) debris.
