The collector motors of washing machines are equipped with electric brushes, which serve to transfer electricity to the motor rotor, and it rotates. These are small parts, consisting of a tip and a long spring. Since their tip is made of a soft material, it wears off over time.
In this article, we will find out how to replace the brushes on an Indesit washing machine.
Signs of breakage
Masters of service centers claim that with proper operation of the washer, brushes can last up to five years. And with rare use of the machine – twice as long. By what external signs can you understand that the brushes are faulty:
- The washing machine stopped in the middle of a wash cycle even though the power was on.
- During the operation of the SMA, extraneous sounds (noise, crackling) are heard.
- The laundry is poorly wrung out as a result of a decrease in engine speed.
- The smell of burning is felt.
- Fault code F02 appears on the washer 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 the replacement of brushes in the Indesit washing machine is necessary, you need to partially disassemble it.
Right choice of
Before proceeding with the repair, you need to get 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.
- Ordinary, consisting of a spring and a graphite rod.
Please note that in order 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 advise the appropriate option.
During the inspection of the electric motor, it may turn out that only one brush has worn out. In this case, it is recommended to replace both parts anyway.
Preparation for repair
Replacing the motor brushes of the Indesit washing machine is a simple repair. You will need these tools:
- Screwdriver slotted or Phillips.
- Torx key 8 mm.
- Marker.
Prepare the washing machine:
- Disconnect the SM from the network.
- Shut off the water supply by turning off the inlet valve.
- Prepare a container to collect water.
- Unscrew the inlet hose from the body, drain the remaining water from it.
- Approach the front panel. At the bottom you will see a hatch – open it by pressing the plastic latches with a screwdriver.
- Behind the hatch is a drain filter.
- Take it out, drain the water, clean it of debris.
- Move the machine away from the wall so that you can get to the back wall.
So, you have prepared the tools and the washer for repair. Get to work.
Step-by-step execution of work
Before you change the brushes on the Indesit washing machine, you need to remove the back wall of the washer. For this:
- Take a screwdriver and remove the two screws that hold the top cover on the back.
- Push the lid away from you, lift it up and set it aside.
- Remove the screws around the perimeter of the back cover.
- Take it off.
- Below, under the tank, is the CM engine.
- To remove the drive belt, pull it towards you while turning the drum pulley. It will fly off easily.
- Take a photo or mark the location of the motor wires with a marker. Then disconnect the wiring.
- Using an 8mm socket wrench, remove the bolts that hold the motor. They can be from three to four pieces.
- Swinging the electric motor back and forth, pull out the CMA from the housing.
Be careful! The engine is heavy.
Now it’s time to inspect the commutator brushes. They are located on both sides of the engine housing. Typically, Indesit washing machines use CAR014UN brushes, which are also analogous to N52A, CAR024UN, UN135. So, choosing one of the models, you will not be mistaken.
To get the brushes:
- Disconnect the wire.
- Move the contact down.
- Pull on the spring and pull out the brush.
To put the parts back in place, first position the graphite tip in the socket. Now compress the spring and also install in the socket, closing with a contact. Connect the wire.
Great! You have completed repairs to replace the electric brushes. It remains to put the electric motor in place. What should be done:
- Bolt the motor in place.
- Connect the wires in accordance with the photo or marking.
- Put the drive belt in place. Immediately put it on the engine pulley, then, turning it a little, on the drum pulley.
- Replace the back cover by tightening all the screws.
- Close the top cover, screw in the two screws.
It remains to connect the car and check the operation of the engine. At first, the motor can be quite noisy until the brushes rub in. Then everything is back to normal.
