Replacing brushes on an Indesit washing machine: how to determine the malfunction of the Indesit washing machine parts, replace them, price, how much do the services of a technician cost?

Modern Indesit washing machines are equipped with a commutator-type motor, one of the main elements of which are electric brushes.

These small parts, pressing tightly against the motor rotor, transmit an electrical impulse that stimulates the uninterrupted operation of the “heart” of the household appliance.

During operation, the graphite tip of electric brushes wears off. As a result, the contact weakens, which immediately affects the quality of operation of the washing machine.

We'll talk about replacing brushes on an Indesit washing machine in the article.

How to understand that parts need to be changed?

Signs that the brushes in the Indesit washing machine motor require replacement are:

blocking the process of spinning washed clothes (the drum rotates intermittently, involuntarily stopping for a few seconds);
stopping the operation of the electric motor (there is voltage in the network and there is no mechanical damage to the washing machine body);
persistent smell of burning and sparks that appeared during operation of the electric motor;
extraneous sounds (crackling, rustling) accompanying the washing process.

Problems with the operation of the electric motor are indicated by error F02, which appears on the display of the washing machine.
A layer of graphite dust can confirm the assumption that the motor brushes require replacement. It is easy to see if you lift the top panel of the washing machine.

Signs of breakdown

Service center technicians claim that with proper use of the washing machine, the brushes can last up to five years. And if you rarely use the machine, it takes twice as long. By what external signs can you understand that the brushes are faulty:

The washing machine stopped mid-cycle even though the power was still on.
During operation of the SMA, extraneous sounds are heard (noise, crackling).
The laundry does not spin out well as a result of a decrease in engine speed.
There is a burning smell.
F02 fault code appears on the washing machine screen, which means problems with the operation of the electric motor.

Based on these signs, you can only assume a malfunction. To be sure that replacing the brushes in the Indesit washing machine is necessary, you need to partially disassemble it.

How to disassemble the washing machine to get to the brushes?

Graphite brushes are small elements (consisting of an elongated tip, a long soft spring and contacts), but to get to them, the washing machine will have to be partially disassembled.

Algorithm of actions:

The washing machine is disconnected from the power supply, water supply and sewerage networks, and moved away from the wall.
Unscrew the inlet hose and drain the remaining water from it.
Using a Phillips screwdriver, unscrew the screws holding the washer cover (remove the panel and set it aside).
Unscrew the fasteners holding the back panel.
Carefully turning the drum pulley, remove the drive belt.
Using an 8 mm socket wrench, unscrew the bolts holding the electric motor.
Carefully disconnect all contacts and remove the motor.

To avoid reverse connection errors, everything that is done during disassembly of the washing machine must be photographed or videotaped. It is especially important to capture the connection diagram of the electric motor contacts.

Preparation for repair

Replacing the motor brushes of an Indesit washing machine is a simple repair. You will need these tools:

Slotted or Phillips screwdriver.
8 mm Torx key.
Marker.

Prepare the washing machine:

Disconnect the SM from the network.
Shut off the water supply by turning the inlet valve.
Prepare a container to collect water.
Unscrew the inlet hose from the housing and drain the remaining water from it.

Approach the front panel. Below you will see a hatch - open it by squeezing the plastic latches with a screwdriver.
Behind the hatch there is a drain filter.
Take it out, drain the water, clean it of debris.

Move the machine away from the wall so you can approach the back wall.

So, you have prepared the tools and the washing machine for repair. Get to work.

How to replace?

After the motor is removed from the washing machine body, access is opened for a detailed inspection of the brushes. These are two protruding plates located on the engine housing .

To disconnect them, first remove the fasteners holding the part (use a Phillips screwdriver), after which the wires are disconnected with pliers.

You can visually assess the wear of parts. If the plate protrudes from the housing by less than 1 cm, it must be replaced.

Depending on your existing experience in repair work, you can replace the brushes in the Indesit washing machine in two ways.

Fully

Algorithm of actions:

Use a rag moistened with alcohol to wipe the engine, contact chips, and motor slats.
Using sandpaper with the finest grain fraction (“zero”), wipe the collector (this is how graphite chips are removed from the surface).
A new part is installed in place of the previously dismantled brush. To do this, a graphite tip is inserted into the socket. The spring is compressed and also inserted into the socket.

The contacts are connected last. To avoid mistakes, during the connection process you need to check with previously taken photos or videos.

Partially

To replace only the worn brush plates (the spring remains old), you need to disconnect the plates from the motor housing and bite off the springs with pliers . A new plate is soldered in place of the disconnected part.

It is important to observe the bevel angle at which the contact is connected to the capsule. Otherwise, there is a high risk of sparks occurring during engine operation.

Loss of motor power

The “coals” ensure the transmission of electricity to the motor rotor windings, thereby causing it to rotate.
The typical service life of electric motor brushes is at least 7 years (with proper use).

Characteristic signs of brush wear:

Extraneous noise when rotating (spinning) the drum
Motor power loss
The smell of burning, burning
The machine freezes during the spin cycle and an error code is displayed
Draining water after starting the program

Brushes for Indesit, Kandy are available with parameters 5x12, 5x32 mm.

For Bosch and Siemens, longer brushes are produced - 5x12, 5x32 mm.

It happens that the wear of the coals is slight, but they are jammed - pinched in the body by dust accumulated in the cracks.

Each ember is installed in a brush holder. It can be disassembled into two halves. Pay attention to how much the brush protrudes.

If the working reach of the brush is less than 7 mm, it must be replaced (both should be replaced).

To do this, disconnect the wire and pull out the contact to remove it. Remember in which direction the graphite contacts are ground.

Remove the back panel and drive belt. Unscrew the mounting bolts and separate the motor from the washing machine tank.

Motors come in three types - single-phase asynchronous, direct drive and commutator.

We determine the serviceability of the engine itself, otherwise replacing the brushes will be a wasted repair.

Using a tester, we measure the resistance of the collector contacts for a short circuit and to the housing. A break in the rotor windings can be easily detected using an ohmmeter by connecting the latter to any adjacent collector lamellas.

Rotating the rotor manually, we measure the resistance between adjacent lamellas - it should be the same. If the resistance increases, there is a winding break.

If everything is in order, inspect the condition of the “coals”. If the working overhang is less than 7 mm, it must be replaced (both should be replaced).

To do this, disconnect the wire and pull out the contact to remove it. Remember in which direction the graphite contacts are ground.

We clean the collector lamellas with sandpaper. We remove dust with a vacuum cleaner. We install new ones, making sure that they fit tightly to the collector.

If necessary, grind off the graphite with sandpaper. Attach the motor to the tank, connect the power wires, but do not put on the drive belt.

We start the spin cycle and rub it in to reduce friction. Next, we assemble the remaining parts.

Replacing brushes on an Indesco commutator motor, which is installed on Arison, HAIER, SAMSUNG, Indesit, Candy:

How to put it back?

The brushes have been replaced - it's time to return the engine to its original place.

Algorithm of actions:

put the motor on the mounting lugs, tighten the bolts;
we check the stability of the motor to ensure there is no wobbling;
return the back panel and lid of the washing machine to their original place;
We connect the washing machine to the power supply, water supply and sewerage networks.

The drive belt is put on the drum pulley only after the first test wash. This is necessary so that you can check the operation of the household appliance with different loads.

Subsequent operation of the Indesit washing machine

The process of installing new brushes has been completed, the electric motor has been returned to its original place - the time has come to test the work done.

Algorithm of actions:

Set the washing program to minimum speed and press the “Start” button. An important point - the drive belt is not on yet!
At the end of the wash, run the program again.
We put the drive belt on the drum pulley. First of all, the belt is fixed to the engine pulley, and then, carefully turning it, onto the drum pulley.
We set a washing program lasting at least one hour. The number of revolutions is minimal. An important point - there is no need to load the ram with linen!

The smooth operation of the washing machine, the absence of foreign odors and sparking indicates that the brushes are installed correctly. A slight noise in the first weeks after repair is considered normal.

Causes of malfunction of the brushes of the Indesit washing machine

Electric motor brushes are reliable, but with intensive use of a household device, they wear out over time, which causes contact loss between them and the motor commutator. As a result, unstable operation of the unit or its complete failure is observed. Also, brush breakage is directly affected by washing clothes with a weight that exceeds the permissible limit specified in the technical documentation.

Where to buy new ones, how much do they cost?

Brushes for Indesit washing machines are made from materials that meet high levels of strength and electrical conductivity. Carbon-graphite plates are distinguished not only by good performance characteristics, but also by efficiency.

With an average intensity of use of the washing machine (no more than two loads per week), graphite brushes are changed once every five years.

You can purchase new elements for your washing machine at a service center that services Indesit household appliances or on specialized websites on the Internet. When choosing replacement parts, you need to remember some recommendations:

It is better to replace only with original brushes (designed specifically for this model of washing machine), the use of so-called “universal” options can cause malfunctions of household appliances;
even if only one brush is worn out, both parts must be replaced, otherwise an uneven load on the rotor will cause malfunctions of the electric motor.

When ordering a new part, just name the make and model of the washing machine and the seller himself will advise the most suitable option. On average, buying a pair of brushes for an Indesit spiral machine will cost 1000 rubles.

Right choice

Before you begin repairs, you need to obtain a suitable replacement. Of course, you can remove the old parts and go to the store with them. To do this, you need to decide what type of brushes are in your engine:

Brushes in a plastic case.
Consisting of three elements - collapsible parts.
Conventional, consisting of a spring and a graphite rod.

Please note that to purchase new parts it is not necessary to immediately dismantle the old ones. You can tell the brand and model of the washing machine to the seller, and he will recommend a suitable option.

During inspection of the electric motor, it may turn out that only one brush is worn out. In this case, it is recommended to replace both parts anyway.

Call a specialist, price of work

In the process of replacing brushes, many moments arise that require certain knowledge and skills (for example, adjusting belt tension, soldering contacts, or disassembling washing machines of older models).

If you have the slightest doubt about your own abilities, it is better to entrust the work of replacing brushes in the Indesit washing machine to professionals.

Masters of service centers servicing Indesit household appliances will quickly and efficiently carry out the necessary diagnostics and repairs of the washing machine. Internet search engines will help you find contacts of service centers.

On average, replacing brushes on an Indesit washing machine will cost 1,500 rubles. The estimate includes:

dismantling of household appliances,
engine dismantling,
diagnostics and replacement of brushes,
assembly and testing of the washing machine.

New parts are paid separately. Upon completion of the repair, the master is obliged to issue a Certificate of Completion to the client.

The lack of documentary evidence of brush replacement, as well as insistent requests to pay in full for unfinished repairs should be a signal that you should not have any business with such a “master.”

A lot of important and useful information about repairing Indesit washing machines is presented in this section.

Lapping

Grinding in to the rotor is an important stage in repairing a washing machine. This is done in order to avoid further overheating of the engine due to the fact that the graphite sparks.

Grinding is carried out as follows:

The engine of the Indesit washing machine is installed back in place and secured, all wiring is connected in place. There is no need to put a belt on the engine and drum.
The machine is connected to the electrical network. Using the control, the “spin” program is selected and set to the lowest drum speed.
Next, you need to turn on the machine and wait for the program to complete.
The belt is installed in place.
The back cover of the machine is screwed on.
After assembly is completed, you need to select a washing mode that takes 1-1.5 hours. There is no need to put laundry in the washing machine. The minimum number of revolutions is set and the wash starts.
After finishing the grinding, you can use the Indesit washing machine as usual.

If the brushes spark after grinding in, this may indicate an interturn short circuit in the motor windings. You should not use such a machine; the engine will still break down, which can cause a fire. It would be best to conduct additional engine diagnostics.

How to change brushes on a washing machine. This is an essential part of the commutator motor, which is used in 90% of SMA - automatic washing machines.

“>SMA, and not only on Indesit.” This motor is powerful, durable and high-speed, with the ability to smoothly change the rotation speed. The main disadvantage is replacement due to wear. They are made of soft material - electrical graphite or coal. This was done in order not to damage the “lamellas”, which are made of copper. Do you use citric acid?

The brushes are pressed against the rotating rotor and transmit electricity. When using the machine with 2-3 washes per week, replacement will be required after 10-12 years. Overloading with laundry leads to increased wear and reduces use time. Build quality is just as important. Famous manufacturers do not offer early replacement.
