Replacing brushes on an LG washing machine: how to understand that you need to change parts of an LG washing machine, where to buy and at what price, how to remove and replace it yourself?

There are no unnecessary parts in the washing machine. Each of them is important because it performs a specific function.

One of the weak points of any machine is the brushes. Over time, they wear off, which entails a deterioration in the quality of washing and spinning.

If the malfunction is not corrected in time, the device may completely fail. Read the article about when brushes on an LG washing machine need to be replaced and how to do it.

When does it need to be replaced?

LG washing machines with commutator motors are equipped with graphite electric brushes. They are needed to transmit electricity to the motor armature. The parts are represented by small rectangular cylinders with copper contacts and steel pressure springs.

When the motor rotates, the surface of the brushes comes into contact with the rotor, so they are subject to wear. Despite the fact that special alloys are used for their manufacture, spare parts are subject to abrasion.

Their average service life is 5 years , subject to active use of the washing machine. The wear process of carbon brushes is accelerated by dust getting into them.

They change shape, causing the engine to malfunction. As a result, the washing machine begins to function improperly.

Signs indicating wear:

Noise and crackling. It appears when the engine is running. Extraneous sounds are heard most strongly from the place where the motor is mounted.
Wet laundry after spinning. The washing machine does not have enough power to cope with this task.
Stop washing. This can happen when running any program.
The appearance of smoke, sparks and a burning smell.
An error code appears on the display. If the electric brushes malfunction, the CE code may appear on the display of the LG washing machine.

Faulty brushes cannot be ignored. The sooner they are replaced, the better. If you continue to operate the device in this mode, serious damage cannot be avoided.

We identify the breakdown

On average, the need to replace the commutator brushes occurs after 7-10 years of operation of the automatic machine. If you use the washer every day, the graphite rods can wear off after 5 years. The equipment itself will “hint” that it’s time to supply new spare parts. The main “symptoms” indicating brush wear:

“freezing” of the device when performing the next washing program with a stable supply of electricity;
grinding and noise when the drum rotates;
weak spin due to reduced engine speed;
“burnt” smell when the unit is operating;
error code F02 displayed on the equipment display. It informs about a malfunction of the electric motor.

Perhaps only one “symptom” will be obvious, or several will be noted at once. To understand that the problem really is with electric brushes, you will have to climb inside the washing machine. The repair is not particularly difficult, so you can do it yourself, at home. If the inspection reveals that only one brush is damaged, it is still necessary to replace the rods in pairs. Let's figure out where to start, what tools will be needed in the process.

How to disassemble an LG washing machine?

To get to the brushes in the LG washing machine, you will have to disassemble it. You can do this yourself by following the following algorithm:

Remove wet laundry from the drum and unplug the appliance.
Disconnect the drain hose from the sewer, turn off the water supply hose.
Unscrew the wall on the back of the machine. It is secured with 4 bolts and inserted into grooves that need to be carefully bent.
You can see the motor and brushes under the tank.
Remove the belt from the drum and motor.
To make sure that the problem really lies in the brushes, they need to be checked. This can be done using a tester, setting it to ring.
Remove the motor and remove the terminals and wires from it. In this case, you need to remember exactly in what position it is located. If you connect it incorrectly, you can burn the motor or control board.

The failure of the brushes is indicated not only by a decrease in their length, but also by broken contacts, as well as cracks in the graphite. Even if only one part fails, both elements must be replaced.

We buy components

First of all, you need to buy new electric brushes. You can select spare parts by telling the manager the make and model of SMA Ariston. An even better option would be to remove the worn rods and take them to the store.

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

When selecting components in online stores, you should study the assortment very carefully. It is imperative to choose a pair of brushes specifically for the specific engine of the Ariston machine, which is why it is so important to know the model and serial number of the washing machine.

How to change?

To replace brushes from a removed motor, you need to do the following:

disconnect the wires that connect them to the engine;
unscrew the screws that hold the brush holders;
remove the brushes from the motor;
remember which side the graphite is beveled on - to do this, you can put a notch on the holder itself;
remove the wire that is welded to the guide - you can use wire cutters for this;
when the wire is disconnected, it will be possible to remove the old graphite; do the same with the second brush;
install new graphite, solder the wire to the place where it was attached before.

If you don’t want to replace the graphite, you can simply install new brushes by screwing them to the motor and connecting the wires. This is the easiest option for replacing parts, but you won’t be able to save a little on repairs, since new brush assemblies are more expensive than graphite.

Before installing new brushes, you need to inspect the rotor and starter . If dust, dirt or traces of graphite are found on them, they must be cleaned with a dry cloth and wiped with a cotton pad soaked in medical alcohol.

Signs of brush wear

It is best to determine the degree of production visually by removing the coals from the engine. This diagnosis is correct.

But there are also indirect signs by which graphite abrasion is determined:

The laundry does not spin, or the drum rotates intermittently, sometimes stopping. With a half load the process occurs, but with a full load it does not.
The motor stopped working. At the same time, there were no voltage drops in the electrical network. You have not moved and the car has not been exposed to external influences.
An error appears indicating problems with the engine.
You smelled a “burnt” smell.
A strange sound appeared - “crackling”.
When removing the top cover, a layer of graphite dust is observed.

How to assemble?

When new brushes are purchased or the graphites in the old guides are replaced, you can begin assembling the washing machine.

Procedure:

The brushes are installed on the motor, screwing them with self-tapping screws to the motor at the mounting points.
Place the wires on the terminals.
The motor is returned under the tank, after which it is secured with bolts.
Put on the belt to check the quality of its tension.
Connect the wires that were connected to the motor.
Close the back cover of the washing machine and screw it in with self-tapping screws.

ProfiEco motor: quiet and economical

Premium Miele appliances are manufactured in Germany using high-quality materials and innovative technologies. The ProfiEco inverter motor is a patented development of German specialists. The operation of this motor is based on the principle of electromagnetic induction. A significant difference from other motors is that the winding current is controlled by an inverter (not brushes). The rotating rotor smoothly picks up the required number of revolutions, which ensures quiet operation.

Since there are no rubbing parts in the inverter motor, unwanted heating of materials and waste of energy during operation have been significantly reduced. The electric motor is able to very accurately control the movements of the drum during washing and spinning. Miele washing machines with ProfiEco can spin at a speed of 1200-1600 rpm. Automatic imbalance control and a unique honeycomb drum ensure that nothing goes wrong with your favorite items.

The design of the new motor does not have graphite brushes or a drive belt, so owners of luxury equipment will not have to deal with replacing these parts. The ability of the inverter to convert alternating current into direct current allows for the most accurate adjustment of the drum speed. The maintenance-free ProfiEco engine is a guarantee of reliable and durable operation. The energy efficiency class of the latest models according to European Union standards is A+++ -10%. They consume even less electricity than required for the highest class A+++.

Subsequent operation of the household appliance

Sometimes new brushes may spark slightly after installation. This is normal.

After several washing cycles, the excess graphite will be erased and the sparking will stop . You can check the functionality of the new brushes by turning on one of the dry washing modes, without loading things.

In order for the spare parts to “break in” immediately after replacing them, it is not recommended to load the drum 100%. It is advisable to wash a small amount of items. Also, do not turn on the spin cycle at maximum speed.

A small number of revolutions will reduce the load on the motor while the brushes grind in. After 5-6 cycles, you can use the washing machine as usual.

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 choose and where to buy parts?

Choosing the right brushes is very important. You need to buy original spare parts that are designed for a specific model of LG washing machine. You cannot buy brushes of different sizes.

They must have the same length and be made of the same material. It is unacceptable to install parts of different hardness. This will cause motor damage.

You need to buy spare parts from trusted sellers. If they are not available in a regular store, you can order online.

The cost of original brushes for an LG washing machine is about 600 rubles . You can save and buy universal parts only if you are sure that they are 100% identical to the original spare parts.

Why are brushes needed?

An electric brush is a sliding electrical contact for transmitting current between stationary and moving parts of the motor (stator and rotor). The brush-commutator assembly provides electrical connection between the rotor circuit and circuits located in the stationary part of the engine. It consists of the commutator itself (a set of contacts on the rotor) and carbon brushes (a sliding contact outside the rotor). The brush-commutator assembly is an unreliable element of the engine design, because the sliding contacts wear out from friction. In terms of reliability and durability, washing machines with an inverter motor perform much better.

The brush contact got its name because in early motor designs it looked like a lot of flexible copper wires. Modern brushes are usually made of graphite or other conductive material, so they are often called carbon (graphite). The main requirement for the material is a low coefficient of friction and low resistivity. Graphite or carbon powder is used as the basis for making the bar. To increase electrical conductivity and mechanical strength, fine copper powder is often added to it, as well as various binders.

Call the master

If you cannot replace the brushes in your LG washing machine yourself, you should seek help from a specialist.

There are several ways to find a master:

Study advertisements in the newspaper or look at notice boards on the streets. Sometimes there are similar offers there.
Contact the service center. In most large cities there are many organizations that professionally repair household appliances.
Ask friends or relatives for the master’s contact information. Perhaps they have used similar services and were satisfied with the quality of work.
Search for advertisements of craftsmen on the Internet. You can find a private specialist or find offers from service centers.
Contact a specialized LG service. If the washing machine is under warranty, then repairs should be performed free of charge.

The cost of services for replacing brushes in an LG washing machine is about 1,900 rubles.
In this case, the price of the parts themselves will have to be paid separately. The specified amount includes the following types of work:

disassembly of the unit;
engine removal;
diagnostics of old brushes;
installation of new elements;
checking the operation of the motor;
assembling the washing machine and testing it.

You can pay for the work only after it is completed. You should not make an advance payment or transfer money to the specialist’s account before he arrives on site. Before deciding on the choice of a specialist, it is advisable to read reviews from other clients.

If a specialist works honestly, he will definitely give a guarantee for the work performed. As a rule, when replacing brushes it is 1 year. The warranty period must be documented, and not just in words.

Where to start?

Next, you need to take care of the tools that will be needed for repairs. Replacing brushes is not difficult; even an inexperienced user can do this task. It is better for the home master to prepare:

a pair of screwdrivers (thin and Phillips);
marker (a regular pencil will also work);
8mm TORX wrench.

You also need to prepare an automatic machine. Necessarily:

unplug the power cord of the washing machine from the outlet;
close the shut-off valve;
remove the inlet hose. Be careful, water will flow out of the tube when disconnected;
remove the garbage filter. It is located on the front wall of the case, below, on the right, behind a special hatch;
Clean the hole formed after unscrewing the filter element from dirt and accumulated debris.

The basic preparation of equipment for work has been completed. All that remains is to move the machine away from the wall to have free access to the rear panel of the case. Then you can proceed directly to the replacement.

Model range of Miele washing machines

When developing modern household appliances, the emphasis is on environmental friendliness and efficiency. Premium washing machines are designed for consumers who value quality, convenience and attractive design. Our online store offers a wide range of frontal and vertical models, as well as combined washing and drying appliances. Classic front-facing machines (for example, Miele WTD160 WCS) are designed for simultaneous loading of 6 to 9 kg of laundry.

Top-loading models (WW650WCS, WW610WCS) are an ideal solution for small spaces. Since things are loaded from above, and not through the hatch, the space in front of the equipment remains free. Miele washer-dryers (WTD163 WCS, WTI370 WPM, WTR860 WPM) are 2 functional devices housed in one housing: a frontal washer and a condensation type dryer. A combination model is an excellent choice if you are desperately short on space.

The manufacturer has provided a large number of installation methods for rational use of space: installation under a tabletop, installation in a column, side by side and full integration into a furniture set. The latest models support the EcoFeedback option: you can see on the display accurate information (forecast) about water and electricity consumption even before the wash starts. At the end, actual data is shown, which practically does not differ from the original ones.

A large selection of models, colors and installation options will satisfy the wishes of the most demanding client. The official warranty for Miele equipment is 24 months (from the date of sale). Delivery of goods is carried out throughout Moscow, St. Petersburg and throughout Russia.

How long can electric brushes last?

To make brushes for washing machine motors, only durable and reliable material is chosen. The finished product must have a high level of wear resistance. At the same time, carbon electric brushes are considered consumables. These parts change frequently. Why is this happening?

According to manufacturers, carbon electric brushes can last about five years without replacement. If the washing machine is used in rare cases, then this period almost doubles. The parts serve well for several years. After that they burn out. For further operation of the washing machine, they need to be replaced. It is worth noting that electric brushes protect the remaining parts of the washing machine from burnout.
