Regardless of the automatic washing machine brand, the device with front loading models is almost identical to different manufacturers. To understand this technique follows any of its owner. This will help to understand how the machine machine works, which could fail with different problems, and will also be able to cope with the breakdown with their own hands.
The main nodes of the machine machine include:
- Housing;
- Tank;
- Drum;
- Water bay system;
- Press service;
- Electric motor;
- TEN;
- Drain system;
- Control block.
Housing
All elements of the washing machine, regardless of the brand - Indesit, LG, Samsung, Ariston, Electrolux, Bosch or the other are located inside its metal case. In the case, the base is distinguished, the front panel with the hatch, the top cover, the side walls, as well as the rear wall.
At the top of the front of the housing, the control panel is located, and in the left corner there is a container for loading detergent (dispenser). Typically, there are 3 cells in such a container (two for powder and one for a liquid means), but they may be greater or less depending on the model (from 1 to 5). The powder loaded into the dispenser through one or more nozzles falls inside the tank under the action of a jet of water.
In the center of the front wall there is a hatch of a washing machine. It highlights parts such as a rubber hatch cuff and a device that is responsible for blocking the hatch during washing. Inside the cuff is attached to Baku through a clamp. Thanks to the locking device, the door cannot be opened in the washing process. Most often in such a device there is a thermoelement, so after the end of washing the door remains closed for some time.
Water bay system
The signal to the water set comes from the control module to the solenoid valve to which the hose for water bay is connected. This hose must be connected to the water supply.

Tank and drum
The tank is considered the main and most voluminous element of the machine machine. It can accommodate 35-60 liters of water. So that during washing the device does not vibrate overly strongly, the tank is not connected to the housing hard. To support it at the top of the machine there are two or four springs, and in the bottom - two or four shock absorber. In addition, to eliminate the imbalance and strong vibration of the tank during washing, concrete counterweights are fixed on it. Thanks to this design, the housing during the work of the technique, despite the fluctuations of the tank, remains fixed.
Inside the tank is a drum bound to belt transmission or direct drive with the engine. Lingerie is loaded into the drum, and after turning on the wash program to it through a plurality of holes, water begins to flow with detergent. The front of the tank is connected to the drum rubber cuff, providing tightness, and in the back of the drum shaft passes through the tank to the bearing node.
For the manufacture of the drum usually use stainless steel, and the tank can be both steel and plastic. The second option is cheaper, but is distinguished by a greater fragility and a smaller service life. Often, the tank has two halves, which are connected by bolts or with a clamp, but in many cars there are unintended tanks.
Drain system
The main elements of the drain system typewriter are a drain pump and a plastic drain corrugated hose 1-4 meter long. One part of the hose is attached to the pump with a clamp, and the second is displayed in the sewer system.
Drain in the norm must be performed several times during washing. In the pump device, a motor, impeller and "snail", to which hoses are connected. The pump is most often synchronous. The pump runs the electronic module.

Since the most frequent malfunction of the drain system is the output of the pump due to its blockage, the machine device provides for easy access to the pump for its regular cleaning. Check and clean the pump filter recommended at least once every 6 months.
Control block
This assembly machine commands all other elements, so it can be safely called the "brain" of the device. It is also called the programmer, an electronic board or control module. It is from such a block that the teams are given, which are performed by the bay system, a case, drum, drain pump and other details.
The control unit is the most complicated and expensive part of the washing machine. The digital indicator is highlighted in its device, thanks to which the user knows everything about the operation of the device. In most models, such an indicator begins to show such an error code. Having learned it to decrypt, you can determine what the essence of the breakage and can I handle it without calling the wizard. If the module itself came out, it should be repaired for its repair or replacement to a specialist.
Sensors
The operation of the control module is based on the control of different sensors sending information about all processes in the typewriter during washing.
Such sensors are:
- Pressostat. This is the name of the sensor, the function of which is to track the water level. Another of his name is a level relay. It is electronic or mechanical, and the principle of its functioning is pneumatic. As soon as the press service sends a signal to the control module on sufficient water in the tank, the machine will continue its work.
- Air chamber. Such a piece of plastic is located next to the drain nozzle and is important for the operation of the pressost. When the tank fills the water, the air pressure in this chamber increases proportionally along with water pressure. Through a small fitting, the pressure is transmitted to the press service.
- Thermostat. Such a sensor is located at the bottom of the tank. The main function of this sensor is to determine the water temperature in the tank and data transfer to the control module.
- Tab. Its main work is to control the speed of the engine, which is important for different washing modes and the pressure process.

Heater
Located inside the tan washing machine is responsible for heating water during the washing process. The power of the heater is most often ranging from 1800 to 2200 W. It is at the bottom of the tank and is considered one of the most vulnerable elements of such equipment. Its breakdown is one of the most common and most often occurs due to accumulation on the surface of the scale of scale.
Engine
The main function of the engine in the washing machine is to ensure the rotation of the drum. Most often, a collector engine is installed in the machine, but you can meet models with an incoleton or an asynchronous engine.
In direct drive models, the engine fastening is made to the drum (to its back wall). This type of electric motor in the washing machine is called more efficient. Its rotation requires less energy, and the level of vibration and noise from the direct drive device will also be smaller. In addition, such an engine takes less space, which allows you to create machinery with compact dimensions.
In models with belt transmission there is a pulley, which is located at the back of the tank. It is connected to the engine by means of a drive belt. When the inclusion of the motor starts the strap movement, the pulley begins to rotate and thereby ensures the rotation of the drum. The main disadvantage of such a car design is the belt wear under the influence of the friction effect. In addition, such a washing machine vibrates when working more than models with direct drive.
