How to independently check the washing machine engine

A washing machine can serve its owners for a long time with proper use. But even the most reliable units sometimes fail, and then the question arises how to independently check the washing machine engine.

Types of engines and their verification

Washing machines from different manufacturers have different types of engines. Depending on the types of these parts, the check will be slightly different.

There are three types of engine:

• asynchronous;
• collector;
• direct drive

Asynchronous motor it is characteristic, first of all, for old automatic machines. In modern devices, this type of parts is rarely used because of its low efficiency.

Collector engine - This is the most commonly used type of spare parts in modern devices.It has a small size and high speed of work, which made it popular for modern manufacturers.

Electric motor direct drive in many respects similar to asynchronous, but has a higher efficiency and smaller size. This engine is used in fairly expensive, but very high-quality models. The most prominent representative of devices with this type of engine are LG company cars.

To check the device, the first thing to do is to remove the front and rear panels of the automatic machine and remove the engine. For collector models, it will be small, but asynchronous and brushless are quite bulky and heavy.

Asynchronous and direct drive motors are practically impossible to test at home, as they are directly connected to the drum.

Can only externally inspect the integrity of the parts or try to replace some of the parts obviously working. If the device works, then lucky, if not, then the call of a specialist repair center is obligatory.

The collector engine can be separately connected to the electrical circuit and check whether the rotor is spinning.However, such a performance check will not give an absolute guarantee of the engine and can not be a reason for finding a car breakdown in another place. Perhaps the engine is now not enough power: he quietly works without load, but he can't do the full drum.

The most frequent causes of breakdowns and their elimination

The most common causes of washing machine engine failure can be:

1. Worn electrical brushes.
2. Damage to the stator or rotor winding.
3. Splitting or peeling of the collector lamellae.

Graphite brushes are easily erased on the collector, and therefore are the most common cause motor breakdowns. Diagnostics of the performance of brushes as follows:

1. Visual inspection inoperative.
2. Check during the work (there should not be sparks).
3. During washing, there should be no clicking sounds.
4. Check the power of rotation of the drum.

If all these procedures have revealed wear of the brushes, then it does not make sense to change them. Although during the cycle the brushes are still erased. Therefore, even if they do not interfere with the full operation of the engine, it is better replace them with new onescorresponding to the model of washing machine.

Damage to the winding can be detected visually, but usually it does not work out by eye. To check, you need a multimeter, which in the resistance measurement mode must be closed on different parts of the wiring and housing.

If a characteristic click is heard in certain positions, the winding is damaged and repairs are required. You can try to restore the winding, but practice shows that the best solution would be simply to replace the whole part.

If the electric motor has the property of jamming, then lamellae may form chips and peels. Detect this is possible only by visual inspection. You can remedy the situation with the help of the skin, which aligns the damaged parts, or by replacing the part.

If the machine does not turn on and there are suspicions about the malfunction of the engine, it is better to immediately turn to the professionals. This is especially true when the machine can still be provided with warranty service. Only a specialist in view of his experience will be able to accurately determine the cause of the breakdown and identify possible ways to solve this problem.
