Replacing brushes on a Bosch washing machine: how to understand that the parts are worn out, how to change them, where to buy spare parts for a Bosch washing machine, at what price?

The operation of an automatic washing machine is organized according to the principle of coordinated operation of all components. To do this, all parts must retain their full functionality.

But as a result of long-term use, the elements of the machine wear out and require repair. One possible problem is the need to replace the brushes.

We will tell you further how to replace the brushes on a Bosch washing machine yourself.

How can you tell if parts are worn out?

Bosch washing machines are predominantly equipped with commutator motors. In such devices, when the rotor moves, contact occurs between the commutator and the graphite brushes.

With prolonged use of Bosch, they begin to wear out. As a result, the engine loses its power or stops completely.

Due to constant friction, the surface of the carbon brushes decreases, which leads to poor contact. These elements cannot be repaired, so they are simply replaced.

Wear of brushes in a Bosch washing machine is determined by the signs characteristic of this breakdown:

uncharacteristic engine noise;
reduction in engine power;
sudden shutdown of the engine, which is not caused by a power outage;
the appearance of a smoke smell when the washing machine is operating;
weak spinning of things due to reduced engine power (even when the speed was set to high);
failures that are characterized by pauses and jerks in engine operation.

But these signs can be “symptoms” of other disorders in Bosch, so an accurate diagnosis cannot be avoided. For example, a decrease in engine power may also indicate problems with the drive belt.

And noise during engine operation can be caused by a foreign object caught between the tank and the drum , a loose bearing assembly, etc. Codes E02 and F21 on the washer display may also indicate a problem with the brushes.

Without partial disassembly of the washing machine and high-quality diagnostics, it is almost impossible to determine the exact cause of the problem.

When is replacement required?

If you install a gentle wash, then in the equipment of the Bosch Maxx 5 and Maxx models, four carbon brushes will need to be replaced once every 10 years (on average). If you choose washing with a high-speed spin, the period of use of the devices should be at least 5 years (advice from the manufacturing company).

You can find out how seriously the brushes of your washing machine are sharpened by calling an experienced technician. T.K. In addition to disassembling and assembling the equipment, the procedure for replacing the brush involves the competent selection of a new element. Let us separately point out that removing the electronic engine in order to carry out the operation is also not easy on your own. If you do not want to harm your washing equipment, replace the carbon brushes with the help of a qualified specialist.

If you see one or more of the following signs of brush failure, it means that you need the services of a repairman right now:

A cracking sound is heard from under the bottom of the machine;

The device sparks;

You smell burnt plastic or other foreign odors;

The device makes noise and noise.

Breakage of the brushes can be caused not only by their grinding, but also by a malfunction of the electrical module or lamellas, or a short circuit of the heating element.

Please note that the new brushes must get used to the structure. Therefore, after installing them, you will be able to observe insignificant sparking and hear a slight rumble.

If you want the electric motor of your Bosch Maxx 5 or Maxx four washing machine to last for the required period, follow our advice:

Avoid extremely frequent washing. Do it once every two to three days maximum. If you need equipment not for domestic purposes, but for commercial purposes, choose professional-class washing machines;

Avoid high-speed spinning or use it as little as possible. Otherwise, you will need to replace the brushes every three years;

Follow the manufacturer's recommendations regarding tank loading volume.

How to get to the brushes?

To access the Bosch motor brushes, you need to carry out a number of preliminary steps. You should start with these points:

disconnect the washing machine from the power supply - pull out the plug from the socket;
close the water supply tap to the washing machine;
check that there are no things in the drum;
move the washing machine away from the wall so that it can be approached from all sides;
check that you have the necessary set of tools for opening the housing and dismantling the motor (screwdrivers, pliers, wrenches, etc.).

After preparation, you can proceed to disassembling the Bosch washing machine. You should act slowly. All removed screws should be put in one place so as not to get lost.

Procedure for disassembling a Bosch washing machine:

Remove the screws that hold the back panel in place.
Remove the back panel and set it aside.
Remove the drive belt from the pulley by prying it with your hand and at the same time turning the large wheel.
Remove the belt from the motor located below the drum.
Place the belt aside.
Take photographs of all engine connections. This will help with subsequent assembly after repair work.
Disconnect the wires by pulling the connectors towards you.
Remove the screws that hold the motor in the socket.
Remove the engine.

The first thing that brush wear will indicate during a visual inspection is graphite dust on the surface of the engine itself. Before replacing Bosch brushes, the motor must be wiped of graphite dust (or run over it with a vacuum cleaner).

Next you need to inspect the collector and measure the resistance with a multimeter . If there is an electrical leak to the housing, then simply replacing the brushes will not be an effective solution to the problem - the motor will not start working.

All about washing machine brushes of various brands

The movable unit of the electric motor, the rotor (they also say the anchor), is connected to the power supply through a pair of dark-colored brushes, to which twisted copper stranded wires with terminals are soldered. The brushes are fixed in a box holder equipped with pressing springs. In the engine, the blocks are adjacent to an iron cylinder: its surface consists of longitudinal copper strips (lamellas), between which grooves are made.

Washing machine motor brushes are made from compressed graphite or coal chips, perhaps with an admixture of fine copper shavings. The combination of the listed parts is called the commutator-brush assembly.

How to change?

To make it easier to work with a Bosch engine, it is best to move it to a table, providing good lighting for the workplace. After this, you can proceed to the process of replacing the brushes.

Procedure:

Disconnect the power wire from the contact of each brush.
Pull out the brush contact and remove it.
If parts show signs of wear, they must be replaced with new ones.
Conduct an analysis of the reservoir condition. Minor scratches can be sanded out.
Insert new brushes so that they are in tight contact with the commutator. If there is no perfect fit, grinding needs to be done. To do this, apply fine-grained sandpaper to the commutator. One brush is installed and rotated in one direction and then in the other direction. After this, the process is repeated with another brush.
Wipe the collector from coal dust.
Connect the power wires.
Secure the brushes with screws.
Rotate the engine by hand to check for proper assembly. If everything is done correctly, you can hear clicks.

New brushes have a surface length of about 3-4 cm, while old ones often wear down to half a centimeter.

Main signs when it is necessary to change brushes

A clear answer that it’s time to change the brushes is given by machine diagnostics. But not many people feel comfortable calling a professional for an inspection. Based on repair experience, RemBytTech service engineers have prepared a list of signs that may indicate the need to replace electric brushes.

Problems with drum rotation. The drum barely rotates, and the machine cannot gain speed during the spin cycle. Or the washing machine does not spin the drum at all, immediately draining the water after filling. Or, it happens that the drum spins a little at the beginning of the wash, after which the machine stops washing and gives an error.
Unstable motor operation. When the machine is fully loaded while washing or spinning, it loses speed.
Noise and sparking brushes. It is noticeable by the smell of metal or burning insulation; also in the darkness you can see a glow at the bottom of the washer, as if from sparklers.

The described symptoms may result in the program interrupting and displaying an error code. The code is displayed on the screen (if there is one) or the indicators blink. More often, wear of the brushes is indicated by an error in the motor, tachometer or spin.

Rules for reassembling a Bosch washing machine

After installing the new brushes, the Bosch motor is ready to be placed in the washing machine body. Procedure:

put the engine in place in the mounting socket;
fix the motor with screws;
we connect all the connectors - for this you can use the photographs taken earlier;
To completely grind in the brushes, it is advisable to carry out the first start without load - the washing machine is plugged into the socket, the “spin” mode is set to the minimum possible speed, the belt is not put on;
this cycle is run without laundry (without load);
disconnect the washing machine from the power supply;
put the drive belt on the motor;
put the drive belt on the large pulley, turning the wheel slowly, making sure that the belt does not come off the motor;
install the back cover of the washing machine;
secure its position with screws;
put the washing machine in place;
connect disconnected communications.

Briefly about diversity

In the first place is the cross-section tangential size;
On the second, the width is the axial dimension;
On the 3rd length the circular size.

Brushes for electric motors of Indesit washing machines are available with parameters 5×12, 5×32 mm. For Bosch units, longer brushes are available: 5×12, 5×32 mm.

Type is the ability of a part to work in more or less saturated conditions. For this purpose, the product is assigned a certain degree of hardness. The hardness properties of brushes of various types are given in GOST 53617-2009. Among brushes with EG brands, EG-14 is considered a product with universal applicability. Softer EG-4 and EG-71: they are designed to work in conditions of average temperatures and uneven loads. EG-74, EG-8 hard brushes are designed to work as part of massive traction devices.

Despite the fact that different types of brushes can fit the same motor, when choosing contactors you must follow the manufacturer’s advice: a very hard graphite surface can lead to increased wear of the commutator. It is better to install soft brushes or universal ones.

Subsequent operation of the household appliance

After the repair has been carried out with the replacement of Bosch brushes, it is necessary to give the new parts time to get used to them.

To do this, it is important to carry out the first 10 washes in a gentle mode - with the drum not fully loaded . Moreover, overload is prohibited.

During the first starts, the engine may be noisier than usual. This is a normal temporary situation. In the future, you can use the washing machine as usual.

To ensure that the installed brushes in Bosch last longer, you must adhere to the following preventive measures:

The drum should not be overloaded. If there are a lot of things to wash, it is better to divide them into several batches.
You should not start the washing machine over and over again without allowing the motor to rest.

Signs of abrasion of parts

Determining whether the brushes are worn out or not is quite simple. There are several signs of their abrasion:

The engine suddenly stopped working. If there were no voltage drops, there was no mechanical damage to the washing machine, most likely the brushes have served their purpose.
During operation of the device, extraneous noise and crackling occurs. It is possible that the graphite is completely worn out and the springs are in contact with the rotor, causing this sound to occur.
Engine power decreases. For example, the drum does not rotate during the spin cycle, and the laundry remains wet.
The washing machine smells like burning.
The corresponding error appears on the display.

Where to buy spare parts, at what price?

The brushes in the engine are replaced not one at a time, but as a set at once. You can purchase spare parts in advance at a specialized store that sells parts for washing machines or order brushes through an online store. When choosing, it is important to consider the Bosch washing machine model. The cost of brushes in online stores on average starts from 300 rubles per pair.

Brushes are original and universal. The first option is preferable. Also, you should not chase cheapness, since low cost often indicates low quality products. It is advisable to select brushes similar to those that were installed previously.

What choice to make

It is imperative to buy identical elements, because installation with different spring stiffness or manufacturing from non-identical material can lead to breakdown of the electric motor and its repair. They also need to be purchased for the engine model that is in the car. To purchase new brushes, you can call spare parts stores, or also go to a service center that services household appliances of this type. You will need to write down in advance the name and series of the device, the type of engine.

Call the master

Replacing Bosch motor brushes is a job that not every washing machine user can do themselves. If you have doubts about your own abilities, it is better to call a specialist from a company that repairs washing machines. All details and the approximate cost of the work can be discussed with the dispatcher by phone.

On average in the capital, replacing the motor brushes of a Bosch washing machine will cost from 1,800 rubles. Plus the cost of the parts themselves. If other faults are additionally identified, the price increases. After completing the work, the master gives a guarantee and conducts testing.

Instructions for the Bosch Maxx 5 washing machine

A short instruction manual is intended to become a guide that will help you quickly understand the newest washing machine. If the annotation is expanded, then it is awkward to read, and many users simply will not do it, but will begin to teach their newest Bosch Maxx at random, which can lead to dilemmas. After a little thought, we decided to release a shortened version of the instructions for the Bosch Max 5 washing machine, collecting in it all the most basic things and discarding the water. And this is what we got.

Disassembling the case

Before starting disassembly work, you should turn off the power to the equipment. To get to the motor, you need to remove the back cover of the machine. Usually, it is held in place by several fasteners, which can be unscrewed using a regular screwdriver.

Then proceed according to this scheme, tested more than once by masters:

Remove the drive belt by pulling it towards you while rotating the pulley. If you do everything correctly, the belt will come off without effort. Put the belt aside and at the same time inspect its condition (it may need to be changed).
Disconnect the wiring from the engine to get it out. To simply remove the wires, pull the connector towards you.
Usually the motor is mounted inside the housing with screws or bolts. Unscrew them to remove the part.

Signs of wear on the electric brush in the engine

The very first sign of a malfunction of the electric brush is that the engine is not running at full strength. If the electric motor begins to work much more slowly or with long pauses, then this is a clear indicator that parts need to be replaced;
If the machine uses water as usual, but the main drum does not rotate or makes strange noises, then this is most likely a sign of wear on the carbon brushes;
The next indicator of brush failure is that the engine begins to spark. Sparks from the engine are a direct indicator that the carbon fiber on the brushes has run out and the metal parts are simply starting to come into contact with each other;
Complete lack of engine performance. In simple words, the engine does not turn on.

Replacing the washing machine motor brush

For repairs you will need:

Slotted and Phillips screwdrivers.
Nut wrenches.
Brand new item.

Turn off the power to the washer. Close the water inlet valve. You will have to dismantle the back panel, so prepare a container and disconnect the inlet hose from the body. Carefully! Water will flow out of it.

It is better to immediately drain the remaining water from the tank so that when the body is tilted, it does not get on the parts.

Open the door under the loading hatch.
Place the container.
Turn the filter plug counterclockwise.

Wait for the water to drain.

How to change brushes on a washing machine? Proceed to dismantle the panel:

Remove the top cover of the MCA by unscrewing the bolts from the back.

Slide it back and remove it from the body.
Remove the screws around the perimeter of the back wall.
Put it aside.

If the belt has come off the pulley, return it to its place. Under the tank you will see the motor leads.

Remove its wiring chips from the connectors. Using a wrench, unscrew the nuts of the mounting bolts. Remove the engine from the housing.

Before changing the brushes in the SMA, unscrew their fastenings and turn off the contacts.

If the rod is worn out by more than half, then the parts need to be replaced. With severe abrasion, their body rubs against the rotor, which leads to sparking.

Rotate the manifold. Does it spin normally? Are the lamellas damaged? If everything is in order, then install new elements on both sides of the engine.

How to position the brushes correctly:

Install the parts into their original slots.
Connect the contacts.
Secure the bolts.

Turn the rotor by hand. During normal contact, clicks will be heard. This means that the repair was successful and you can reassemble the machine in reverse order. The stages of work are shown:

You can carry out repairs without the help of others, saving on the services of a specialist. To extend the life of the parts, do not overload the drum with laundry and follow the manufacturer’s recommendations.

Signs of damage.

Most likely, before they wear off completely, the brushes will spark a lot.
Also, if after turning on the machine, it may not spin the drum.
When you turn on the washing machine it says an error.

Purchase and selection.

Before replacing motor brushes, purchase new ones. To do this, you may need the make and model of your washing machine. You will most likely find the model in the warranty card or on a special plate on the washing machine. This sign may be on the back, on the side, or under the hatch of the washing machine.

Lifetime.

Typically, washing machine brushes from the factory last about 5-10 years, depending on the number of washes and the volume of laundry loaded. After replacement, the period will most likely be even shorter, about 3 years. Due to the fact that the brushes work in pairs with a commutator, which has already served for many years and has a lot of wear.

Understanding the powder receptacle

The washing machine of this brand has a standard powder receptacle of a traditional rectangular shape. You can remove it by pulling the handle all the way. A special stopper prevents the cuvette from being pulled out completely. When you pull out the powder receptacle for the first time, you will see three compartments.

Compartment No. 1 (if you look from right to left) is marked with the Roman numeral I, so it is simply impossible to confuse it. It is intended for preparatory washing, so you will not use it often.
Compartment No. 2 (located in the middle) is marked with a flower design. You should pour air conditioner into this compartment, sprinkle starch or rinse aid.
Compartment No. 3 (when looking from right to left) is marked with the Roman numeral II. We will use this compartment in most cases. Powder for the main wash, Calgon, and stain remover are poured into it.

In this case, the powder should be poured into compartment No. 1 if the program provides for preparatory washing. Namely, preparatory washing may be required when we wash very dirty cotton or mixed laundry. Do not overdose on powder, conditioner, and especially bleach. This can destroy not only the laundry, but also the washing machine (excessive foaming from excess powder can destroy the electrical module).

Care and safety: basic rules

You need to take care of your Bosch washing machine, then it will serve for a long time. After each wash, be sure to leave the hatch ajar so that air can get inside. Otherwise, mold may form in the washer and a nasty smell may appear. It is also necessary to leave the powder receptacle slightly open.

After finishing washing, wipe the cuff of the hatch, the internal surfaces of the drum, and the internal compartments of the powder cuvette with a cloth. You also need to unscrew the garbage filter once every 4-5 washes and wash out the dirt that accumulates there over this period of time. Be especially careful when putting laundry into the machine; do not forget to inspect the pockets so that small objects under no circumstances fall into the drum, and from there into the tank. When you have finished using the machine, be sure to close the tap.

For safety reasons, do not allow small children near the washing machine. Do not overload the machine with a very large amount of laundry. Do not add too much detergent or rinse aid. If, after turning on, the machine refuses to wash and displays an error code, you should immediately contact an authorized service center.

So, we consider the annotations indicated in our shortened version to be more necessary. If you would like to get acquainted with a detailed version of the annotation for the washing machine of this model, then nothing could be easier, because it is attached to this publication. Fortune!
