How to check the engine of the washing machine for serviceability?

In the modern world there is a huge number of household appliances that make our life much more comfortable. A washing machine is a household appliance that can fail for a variety of reasons. However, most types of breakdowns can be eliminated independently, without resorting to the help of professionals whose cost of services is quite expensive. As practice shows, the most common problem is engine failure due to its physical wear, voltage drop or any other factors. The problem with this is that the SMA motor is quite expensive, so many people are interested in the question of how to check the engine of the washing machine. About how to perform diagnostics and eliminate not very complicated faults, you will learn further.

Modern versions of engines AGR

Instead of obsolete washing machines with a centrifuge came more new models, assembled on the basis of modern engines, which are more prone to physical deterioration and are more often out of order. Therefore, before you talk about how to test the engine of a washing machine, you need to understand what types they exist. Nowadays one of the following types of motors can be installed in the AGR:

1. Asynchronous motor: it is considered obsolete and occurs in older washers. It has a very simple design and quite a quiet work.
2. Collector motor: the most common type, which is installed in the vast majority of modern washing machines. The principle of operation is based on bringing the drum into motion by means of a belt. Has a more complex design compared to asynchronous motors, so fix it with your own hands is much more difficult.
3. Direct drive motor: a modern version of motors for washing machines, which is attached to the drum directly. It has the highest efficiency, however it is also quite expensive.

Each type of engine has individual design features, so the diagnosis and repair are significantly different. So that you can determine the malfunction of the motor in your CMA model, you need to talk about how to check the engine of the washing machine in each particular case.

Determining the malfunction of a belt drive motor

In most modern washing machines, which can be purchased at a specialized store, collector motors are installed. They have a relatively simple design and are very easy to diagnose and repair. However, in order for you to identify a fault in your AGR, you need to know how to check the engine of the washing machine. To do this, you need to get inside the device and independently find out the serviceability of all the nodes, and then replace the worn parts.

Diagnosis of direct drive motors

This type of engine is used exclusively in Samsung washing machines. Despite the fact that it has a rather complex design, nevertheless engineers have provided the possibility of diagnostics at home. How to check the engine washing machine "Samsung", you ask?

Everything is very simple! You just need to go to the appropriate subsection of the menu, after which the system will perform the diagnostics of all the AGR nodes and display the corresponding code on which you can determine the type of failure. However, it should immediately be noted that in this way a small malfunction can be diagnosed. More serious cases require the call of qualified specialists.

Checking the electric motor

The most sold in our country are the SMA Indesit. They use an electric motor, which has a very complex design. Nevertheless, each person will be able to independently perform engine diagnostics and repair if he knows how to check the engine of the washing machine with a multimeter. To do this, you will need to remove the rear and front covers of the housing, and then dismantle the unit, having previously disconnected it from the power. Then you should check the reliability of the connection of all the nodes, and then apply power to the motor. If it works, it means that the reason for the inability of the AGR is something else. If you are not sure that you know how to check the engine on the washing machine "Indesit" yourself, then in this case it is better to turn to specialists.

Types of breakdowns

There are quite a few different types of motor breakdowns, but most often the problem is related to the following reasons:

• Breakage of electric brushes;
• Damage to the winding of the rotor or stator;
• Failure of the collector sipes.

If you know how to check the engine of the washing machine, then any of these faults can be detected and eliminated by yourself, without contacting the service center, while still saving money.

Replacement of electric brushes

Electrobrushes are special tubes made of graphite, which are fed with current. Most often, they break down as a result of loading too much laundry into the tank, and also as a result of physical wear. Eliminate this fault is very simple, and a set of spare parts is quite cheap. The main thing is to choose suitable brushes for your model of washing machine.

Replacement of lamellas

So, now you know how to test the engine of an Indesit washing machine. What should I do if, during the diagnosis, it is found that the lamellae are out of order? In the case of a breakdown of a small complexity, it is possible to eliminate the malfunction by punching the manifold and lamellas with sandpaper. After grinding, it is very important to clean everything thoroughly, so that there is no dust, dirt or metal shavings anywhere. If the breakdown is very difficult and it is impossible to eliminate it at home at home due to the lack of special equipment, then in this case it is worthwhile to turn to the professionals for help.

Damage to the winding of the rotor or stator

If you notice that the washing machine does not work at full capacity, then the reason, most likely, is the winding of the rotor or stator.

Failure can occur as a result of interruptions in the electrical network, overheating of the unit or physical damage to the winding. To find out a malfunction it is possible by means of the tester, having called resistance between lamellas. It should be in the range of 0.1 to 0.4 Ohms. If the readings of the device are lower or higher than the norm, then the problem really is in the winding. It is necessary to eliminate this fault as soon as possible, since power interruptions during the operation of the AGR can lead to the failure of other electrical nodes, the cost of which can be prohibitive.
