Brushes for the Indesit washing machine: selection and replacement

Indesit washing machines operate on the basis of a collector motor, in which special brushes are located. After several years of operation, these elements will need to be changed, since they tend to wear off. Timely replacement of brushes is a guarantee of high-quality operation of the unit. Let's take a closer look at the selection and replacement of brushes for a washing machine.

A washing machine is a device with a complex design; an electric motor is considered to be its heart. Indesit washing machine brushes are small elements that drive a motor.

Their composition is as follows:

• a tip that has the shape of a parallelepiped or a cylinder;
• long spring with soft structure;
• contact.

Machine brushes must be manufactured to meet certain requirements. The material of production of these elements must be characterized by strength, good electrical conductivity, and minimal friction. These are the qualities that graphite, as well as its derivatives, have. In the process of use, the working surface of the brushes is transformed and it acquires a roundness of shape. As a result, the brushes follow the contours of the collector, which provides maximum contact area and excellent glide.

In electrical engineering, it is known to use three types of brushes for the motor of washing machines, namely:

• carbon-graphite;
• electrographite.
• metal-graphite with copper and tin inclusions.

An Indesit washing machine electric motor brush is usually pressed against the motor manifold using a steel spring. From the rear, a wire is embedded in these parts, at the end of which there is a copper contact. The latter acts as a place of connection to the mains. With the help of brushes that are located on the sides of the electric motor collector, the current is directed to the winding of the rotor, which rotates. All this is considered the key to the normal functioning of the washing machine engine.

Experts say that careful and correct use of the washing machine is a guarantee that the motor brushes can last for a long time. In this case, they will need to be replaced in about 5 years from the date of purchase of the unit. If the machine is used infrequently, then these parts will last 2 times longer.

Malfunctioning brushes for the motor can be identified by such signs as:

• the unit stopped at the time of washing, despite the fact that there is electricity in the network;
• the washer crackles and makes noise during operation;
• the laundry was wrung out poorly, since the engine speed was reduced;
• there is a burning smell;
• the washing machine displays the code F02, which indicates a problem with the electric motor.

Having discovered one of the above signs, it is worth thinking about the fact that it is time to change the motor brushes. However, before this, the washing machine will need to be partially disassembled.The procedure for inserting new parts into the housing and soldering some of the elements associated with the motor and brushes is not difficult. For work, the master will need tools such as a slotted screwdriver, an 8 mm torx wrench, and a marker.

The procedure for preparing the washing machine includes the following steps:

1. the unit must be disconnected from the electricity network;
2. shut off the fluid supply by turning the inlet valve;
3. prepare a container in which water will be collected;
4. dismantle the inlet hose from the body, and then rid it of the existing water inside;
5. open the hatch on the front panel by pressing the plastic latches with a screwdriver;
6. get out the drain hose, which is located behind the hatch, and rid it of debris, liquid;
7. move the machine further from the wall, thereby providing yourself with a comfortable approach to it.

To replace the brushes on the Indesit washing unit, it is worth dismantling its back cover as follows:

• using a screwdriver, unscrew a pair of self-tapping screws that are necessary to hold the top cover from the back side;
• push the lid, lift it up and put it aside;
• unscrew all screws in the rear cover perimeter;
• remove the cover;
• find the motor that is located under the tank;
• remove the drive belt;
• mark the location of the wires with a marker;
• dismantle the wiring;
• using a socket wrench, it is necessary to unscrew the bolts that hold the engine;
• by rocking it is necessary to remove the motor from the washer body.

After carrying out all the above measures, you can proceed to inspect the manifold shields. To remove the brushes, you will need to perform such activities as:

1. disconnect the wire;
2. move the contact down;
3. pull the spring and pull out the brush.

To install the parts in their original place, you will need to place the graphite tip in the socket. After that, the spring is compressed, installed in the socket and covered with a contact. Next, connect the wiring.

After changing the electric brushes, you can proceed to installing the engine in its original place, for this, perform the following steps:

• fix the motor in the same place with bolts;
• connect the wires in accordance with the drawing with a marker;
• put on the drive belt;
• install the back cover, tighten each screw;
• close the top cover by screwing in self-tapping screws.

The last step in working on replacing the brushes will be to turn on the washer and check if it works. The consumer should know that immediately after the replacement, the unit may operate with some noise until the brushes are rubbed in... Replacing these parts of household appliances can be done by hand at home, subject to the instructions. But if the owner is not confident in his own abilities, then you can use the help of professionals. Often this procedure does not take much time, therefore it is paid inexpensively.

Brushes on the motor are a must in every model of the Indesit washing machine. Thanks to them, the engine is characterized by power, durability and high revs. The only drawback of these elements is the periodic need for replacement.
