Brushes for electric motors for washing machines: how to choose and replace electric grids Indesit, Bosch, Hotpoint Ariston, Ardo, Beko, Zanussi, Candy, Siemens, Samsung

An ordinary owner of a washing machine usually does not think about the internal arrangement and operation principles of this useful device. For us, the main thing is that the styaralka function properly, "perfectly" performing its main tasks - washing, rinsing and spinning the laundry.

This continues until one day we notice a malfunction in the work of our assistant. Then at least elementary knowledge about the device of household appliances are very useful. It is at this point that most of us first carefully read the user's manual and learn a lot of new information that every owner of the styralka should ideally know.

Today we will tell you about electric brushes, which are one of the most important elements of the engine of the washing machine. From this article you will learn about what they are, what they need and how to properly replace the electric brushes.

Electrobrushes are the details of the engine of the washing machine necessary to ensure contact. The brush is a small metal device consisting of a cylindrical or cubic tip, a long spring and the contact element itself.

The principle of the action of the electric brushes is that they transfer electric energy from the external circuit to the winding of the motor rotor, as a result of which it rotates.

Different types of electric brushes are used in different models of washing machines;the main difference between them is the material for manufacturing the clamping element. Most often, the engines of household appliances are equipped with the following types of electric brushes:

• copper-graphite;
• coal-graphite;
• electro graphed.

Brass( contact material) and steel( spring material) are also used for the manufacture of motor brushes.

So, for the manufacture of electric brushes, which are equipped with washing machines, choose only very strong materials with good wear resistance. But, meanwhile, the brushes of the electric motor are considered "consumables" - parts that are subject to frequent replacement. Why does this happen?

On assurances of manufacturers of home appliances, on the average electrobrushes are capable to serve 5 years, and at rare use of a stylalki - twice longer. This is quite true: the brushes regularly serve for several years, and then burn out and need to be replaced. Thus, they protect other parts of the motor from wear and tear, which will be more labor-consuming and cost more.

The fact that the lifetime of the electric brushes has come to an end, and the replacement of these elements is needed, is signaled by the following signs:

• sudden stop of the washing machine motor, not connected with voltage drops and electricity cut-off;
• occurrence of extraneous noise during washing and spin-off( cracking or tapping);
• reduction in engine power - this is indicated, for example, by the reduction in speed, as a result of which the laundry is not pressed badly;
• appearance of smell of smoke or burning during unit operation;
• appears on the display of the error code associated with problems in the engine.

• Specialists recommend replacing the "native" electric brush only on the original( that is, from the same manufacturer, and designed directly for this model of the stylalki).On sale there are also universal options, but they can cause malfunctions in engine operation.
• Even if only one brush is worn out, both need to be replaced, since otherwise the load on the rotor will be distributed unevenly, which will lead to new malfunctions.
• Before purchasing replacement brushes, determine which type of brushes have been installed in your washing machine. There can be three variants: brushes in a single plastic body, demountable brushes consisting of three elements or simple brushes, which are graphite rods with copper contacts.

If, for the diagnosis of malfunctions in the operation of the washing machine, you have turned to a repairman for help, then most likely he will replace the electric brushes. If you managed to find the fault yourself, then you can replace the spare part yourself. We will describe in detail below how to do this.

The first thing to do is to disassemble the styralka to get to the engine and extract the parts to be replaced. Before this, turn off the unit from the mains, disconnect the hose set and drain the water.

Then proceed in this order:

• unscrew the fasteners fixing the back panel, and carefully remove it;
• remove the drive belt from the pulley;
• unscrew the bolts with which the rotor is fixed to the drum, remove it;
• photograph the location of all the elements we need;
• alternately remove the electrobrushes from the sockets, disconnect the contacts;
• plates of copper, located on the collector, slightly scraped nazhdachkoy;
• we do the same procedure with new electrobrushes, we collect copper dust with a vacuum cleaner;
• install brushes in the socket.

The assembly of the device is carried out, constantly checking with the photograph taken earlier, which fixes the location of all important engine elements. First we put in place the electric motor. Before we put the drive belt on the pulley, we check the operation of the new brushes. To do this, we connect the washing machine to the network and start the spin program. If you observe the sparking of brushes in the first minutes of work, do not be frightened - it's absolutely normal. Having convinced of the serviceability of new spare parts, we again disconnect the machine from the mains, return the drive belt and fix the back panel.

The process of replacing the brushes for the electric motors of the washing machine Bosch is shown in the video of Vladimir Khatuntsev.

If you are not confident in your own power, then it is better to trust the professionals to replace the brushes - they will cope with this task quickly and at a very reasonable price. The purchase of new brushes, too, most likely, the master will do - he will be able to choose the right model, compatible with your styralka. The price for this service will depend on the region of your residence, but on average it is about 1000-1500 rubles. The cost of brushes depends on the manufacturer and model of the machine. Owners of washing machines Indesit, Bosch, Hotpoint Ariston, Ardo, Beko, Zanussi, Candy, Siemens, Samsung must calculate the amount ranging from 300 to 2000 rubles.
