How to replace brushes on an Indesit washing machine?

How to replace brushes on an Indesit washing machine The SMA commutator electric motor consists of a stator, a rotor, a tachometer, a metal housing and at least two electric brushes. They are necessary to supply electrical energy to the rotor, and consist of a graphite tip and an elongated spring. Over time, the parts wear down on the collector, and in order to return the washer to working order, you will have to replace them. Let’s look at how to change brushes on an Indesit washing machine, what “symptoms” will tell you about their erasing, and clarify the list of tools that will be needed in the process.

How does the malfunction manifest itself?

Experts assure that if the washing machine is used correctly, the electric brushes will only need to be replaced 5 years after purchase. And if the unit is not used daily, they can last 10 years. The Indesit machine itself will tell you when it’s time to replace the brushes. The main “symptoms” indicating the need for repairs:

“freezing” of the washing machine in the middle of the cycle when electricity is properly supplied;
noise and crackling when the drum rotates;
poor, insufficient spin due to reduced engine speed;
burning smell when equipment is operating;
fault code F02 displayed on the machine screen. It indicates that the motor is not working properly.

One or a combination of several signs at once may indicate the need to replace the engine brushes. To make sure that the problem is definitely in them, you will have to partially disassemble the washing machine. If, upon examination of the MCA, it turns out that only one brush is damaged, both elements still need to be replaced. There is nothing complicated in the work ahead, so you can handle it yourself.Let's figure out how to properly replace the electric motor brushes, which will be needed to repair the “home assistant.”

Buying new brushes

Preparing for the job will include purchasing new brushes. You can remove worn-out items and take them to the store. It is important to determine what type of brushes are installed in your brushed motor. These can be electric brushes in a housing, standard ones, including a spring and a graphite rod, etc.

Replacement brushes must be purchased specifically for your brand and model of automatic washing machine.

When visiting the store, it is not necessary to have removed old brushes with you. It is enough to tell the seller the SMA model. buy new brushes

Ahead of renovation work

The next stage is preparing the tools necessary for repair. In fact, changing brushes on an Indesit machine is quite easy; even an inexperienced user can cope with this task in about an hour. So, the home handyman should have on hand:

two screwdrivers: slotted and Phillips;
8 mm Torx key;
pencil or marker.

You should also prepare the washing machine itself. Necessary:

de-energize the equipment;
close the shut-off valve;
disconnect the inlet hose, drain the remaining water from its cavity into a previously prepared container;
Unscrew the garbage filter (it is located in front of the washing machine, in the right corner behind a special panel), drain the water and clean the element from dirt and debris.

Then all that remains is to remove the CM from the wall in order to have free access to the back of the case. So, the preparatory stage will be completed, you can immediately begin work on replacing the brushes.

Replacement instructions

As is already known, electric brushes are located in the SMA engine.To get to the motor, you need to remove the back wall of the washer housing. How to do it:

unscrew the two bolts securing the top cover and remove it;
Unscrew the bolts holding the back wall and move the panel to the side.

The electric motor is located directly under the washing machine tank. To remove the drive belt, begin to pull it towards you, gently turning the pulley. Be sure to take a photo or mark with a marker the wiring diagram for the motor wires before disconnecting them. Afterwards you can remove the wiring.

Using an 8 mm wrench, unscrew the bolts securing the motor. Grab the engine and start rocking it. This will help remove the element from the washing machine body. Please note that the engine is quite heavy, so rely on your own strength. brush replacement procedure

Afterwards, you can begin to inspect the electric brushes. They are located on the sides of the electric motor. In most cases, Indesit washing machines use brushes CAR014UN; their analogues are elements N52A, CAR024UN and UN135.

To remove the electric brushes you need:

disconnect the cable;
move the contact down;
pull out the brush, carefully stretching the spring.

Subsequent installation of parts proceeds as follows:

a tip is inserted into the socket;
the spring is compressed and also installed in the socket;
the brush is closed with a contact;
wire is connected.

Next you need to put the motor in place. The algorithm will be reversed:

secure the engine with fixing bots;
connect the wiring (referring to the photo or marking);
Pull the drive belt into place. First it is put on the engine pulley, then on the wheel;
Reinstall the back wall of the case, secure it with self-tapping screws;
Reattach the top cover, securing it with bolts.

At first, until the electric brushes “grind in,” the engine may make noise during operation.

After several washing cycles, the operation of the Indesit washing machine returns to normal. As you can see, it is possible to replace the brushes yourself, without the help of a specialist.
