How to replace brushes on an Ariston washing machine?

Electric brushes are an integral part of the washing machine's commutator motor. They are represented by a graphite tip with a spring. Their function is to supply energy to the rotor. Over time, the brushes in an Ariston washing machine need to be replaced due to their wear. Let's look at how to do this and what symptoms indicate component wear.

Identifying the breakdown

On average, commutator brushes need replacing after 7-10 years of use. If the washing machine is used daily, the graphite rods can wear down after 5 years. The machine itself will indicate when it's time to install new parts. The main symptoms indicating worn brushes are:

• the appliance freezes while running the next washing program with a stable power supply;
• grinding and noise when the drum rotates;
• weak spin due to reduced engine speed;
• "burnt" smell when the unit is operating;
• Error code F02 appears on the equipment display. It indicates a malfunction in the electric motor.

There may be only one obvious symptom, or several at once. To determine if the problem is truly with the brushes, you'll have to get inside the washing machine. The repair isn't particularly difficult, so you can do it yourself at home. If, upon inspection, it is discovered that only one brush is damaged, the rods must still be replaced in pairs. Let's figure out where to start working and what tools you'll need in the process.

We buy components

First, you need to buy new brushes. You can find spare parts by telling the manager the brand and model of your Ariston washing machine. An even better option is to remove the worn brushes and take them to the store.

It is very important to determine what kind of brushes are in your engine: with or without a housing, with contacts coming out from the middle or from the corner, etc.

When choosing components online, carefully review the selection. Be sure to select the right pair of brushes for your Ariston washing machine's specific motor, so knowing the model and serial number is crucial.

Where to start?

Next, you need to gather the tools you'll need for the repair. Replacing the brushes is easy, and even an inexperienced user can handle it. A DIYer should have the following items ready:

• a couple of screwdrivers (thin and Phillips);
• marker (a regular pencil will also work);
• 8 mm TORX key.

You also need to prepare the automatic washing machine. It is mandatory:

• unplug the washing machine's power cord from the socket;
• close the shut-off valve;
• Remove the inlet hose. Be careful, water will leak from the tube when disconnected;
• Remove the debris filter. It is located on the front wall of the housing, on the bottom right side, behind a special hatch;
• clean the hole formed after unscrewing the filter element from dirt and accumulated debris.

The basic preparation of the equipment for work is complete. All that remains is to move the machine away from the wall to gain easy access to the rear panel of the housing. Now you can begin the actual replacement.

Description of repairs

The brushes are located in the Ariston washing machine's commutator motor. Therefore, the first step is to access the motor. To do this, you need to:

• unscrew the two screws holding the top cover and move it to the side;
• remove several bolts securing the rear panel of the case and detach it.

The collector motor is located immediately under the tank of the automatic machine.

The further algorithm of actions will be as follows:

• Remove the drive belt. To do this, pull the rubber band toward you and carefully turn the drum pulley;
• take a photo or draw a diagram of the motor wiring connection;
• disconnect the wires and contacts connected to the engine;
• Using an 8 mm wrench, unscrew the motor securing bolts;
• Grasp the engine and begin rocking it. This will help remove the component from the housing. Keep in mind that the engine is very heavy, so use caution when lifting.

The next step is to inspect and replace the brushes located on the sides of the electric motor. To remove them, you need to:

• disconnect the wire;
• move the contact down;
• stretch the spring and remove the brush.

Next, a new part is installed in place of the old one. The procedure is as follows:

• install the tip into the socket;
• compress the spring and put it back there;
• close the electric brush with a contact;
• connect the cable.

Replacing the second brush is similar. Afterward, you need to replace the motor and reassemble the washing machine body. The steps are performed in reverse order:

• secure the electric motor with bolts;
• connect the power wiring (be sure to check the photo or sketch);
• Tighten the drive belt. First, place the rubber band on the motor pulley, then on the drum wheel;
• place the back panel of the case, screw the screws into the grooves;
• put the top cover back in place.

Then the washing machine moves to its place, connects to the water supply. Until the brushes are “worn in”, noise may be observed when the electric motor is running. However, this problem will resolve itself after several washing cycles.

So, replacing the brushes requires a minimal set of tools and knowledge of how Ariston washing machines work. It's just important to select the right components and strictly follow the repair instructions.
