How is the Samsung washing machine

How is the Samsung washing machineUsually, it doesn’t occur to users to deal with the internal structure of the Samsung washing machine, but when any malfunction occurs, interest in this issue arises instantly. In order to repair the equipment yourself, you need to study the unit diagram, to understand where the parts and components of the machine are located. Most SMA have a similar device, the difference can be observed only in some elements, now we will examine in detail exactly the Samsung brand washing machines.

What parts does it consist of?

In order to be able to correctly diagnose breakdowns and correctly repair the washing machine, you should figure out what structure the device has. Any Samsung washing machine, regardless of the type of download, contains the following basic elements:

  • electric motor;
  • tank;
  • pump
  • several types of nozzles;
  • detergent dispenser;
  • various springs and shock absorbers;
  • heating element (TEN);
  • drain filter;
  • electric pump;
  • drum pulley;
  • a snail;
  • temperature sensor;
  • SMA control module;
  • special counterweights;
  • sunroof locking device;
  • intake solenoid valve;
  • the cuff of the hatch door;
  • fluid level switch;
  • power unit (is the power source of the entire device);
  • drain and bulk hoses;
  • CMA control panel.details SM Samsung

The design of the machine consists of the listed basic parts. All elements are located in the housing. If we talk directly about the metal housing of the washer, then it consists of side walls, top, front and back covers and bottoms. How the hatch is positioned, horizontally or vertically, depends on the type of load selected. In order to better understand how the machine is arranged, we will take a closer look at some of the individual elements, analyze what tasks they solve and what to do in the event of a component failure.

Control unit

With the help of the power unit, power and control of all elements of the washing machine is provided. It is the electronic module that gives the signal to turn the unit on and off through the wiring connecting the control board and each CMA unit.

All special programs, additions, washing modes are performed and regulated by this unit. That is why, if any one element of the module breaks down, then any part of the washer can stop functioning. To control the main tasks, for example, filling the tank with water or rotating the drum at the desired speed during the spin cycle, the power unit has semiconductors that are responsible for each function control board

One of the parts of the control module is the CMA control panel. By pressing the buttons or rotating the program selector, the user independently selects the preferred washing mode, spin speed, water heating temperature, and with these actions transmits a signal to the power unit, which is then responsible for the normal fulfillment of the given conditions.

Important! A malfunction of the control unit is considered a serious failure, which is difficult to eliminate, therefore, it is worth inviting a qualified technician to repair the module.

Level sensor and filling valve

The liquid level switch (aka pressure switch, level sensor), as the name implies, controls the volume of water in the tank. The pressure switch measures the pressure in the tank and sends an information signal to the control unit. The electronic module, having received information, instructs the filling valve to stop collecting water from the communications.

The inlet valve can have 1 to 3 coils. It is they that transmit voltage, which allows the valve membrane to open and begin to function. While the control unit receives a signal about the need to start water intake, the membrane opens and begins to act.As soon as the voltage ceases to be supplied to the coils, it closes.filling valve

These two elements are not described together by chance; they constantly interact. The scheme is as follows: the filling valve draws water, and the level sensor controls the optimal volume of liquid, preventing underfilling or overflow.

Motor and tachogenerator

This pair of parts also works together. The motor “makes” the drum rotate, and the tachogenerator makes sure that the number of revolutions corresponds to the specified one. The tachometer helps the control module to control the speed of the motor, since the rotation speed should be different for each washing mode.

The electric motor of the washing machine contributes to the correct rotation of the drum at a given pace. Most modern Samsung washing machines are equipped with inverter motors. In this case, the motor is attached directly to the drum, thereby achieving greater efficiency and engine power. This design is reliable and durable, breakdown of the inverter motor is extremely rare.engine

The collector motor drives the drum thanks to a special belt. In this case, wear of the electric brushes occurs, so from time to time the motor will need to be repaired.

Heating element and temperature sensor

The function of the heater is to heat the water in the tank to the desired temperature. Each of the washing modes requires a certain temperature, so the control unit, having received a signal about the program selected by the user, transmits to the heater the set degree of water heating.

The temperature sensor monitors the temperature, and after reaching the specified degree it transmits a signal to the power unit. The thermostat is presented in the form of a metal pipe installed directly in the housing of the heating element. Having received a signal from the temperature sensor, the main unit automatically turns off the heater.

Springs, shock absorbers and counterweights

Using these components prevents the oscillation and "bouncing" of the washing machine during operation. This is very important, otherwise the machine during the spin cycle would simply destroy itself from the inside. What details are we talking about?

  1. Shock absorbers fasten the bottom of the tank to the body of the CMA, and prevent it from bouncing during the spin cycle and hitting the walls.
  2. The springs support the tank from above, their function is very similar to the purpose of the shock absorbers.
  3. Counterweights are weighting blocks, they are connected to the outer surface of the tank and serve to maintain balance.

When the machine is operated, the counterweights can be destroyed by strong vibration. However, in most cases, their mounts are just a little loosened, tightening which can deal with the problem of “rattling” of the washer.

Locking device and cuff

The sunroof locking device is nothing more than an electronic lock that closes the door before washing. When the user closes the hatch, he activates only a mechanical lock, and after starting the program you can hear a click - this is how the electronic door lock is activated. Only after such a signal does water begin to collect in the tank. UBL prevents accidental opening of the door during washing.hatch lock

The cuff serves for more reliable closing of the hatch. It is a sealing gum that protects from the beginning of the process of water flowing through the gap between the SMA housing and the hatch door. Care must be taken to keep the cuff clean, dry and undamaged. If the rubber band breaks, you should not operate the machine until the malfunction is eliminated, as liquid from the drum will spill onto the floor.

Snail, filter, pump

A pomp is a special pump that serves to pump waste water from the drum after the preliminary or main wash process, rinse. In Samsung washers, you can find two types of pumps:

  • synchronous;
  • asynchronous.

The internal filling of the pump is standard; this is the motor and the impeller. A snail is attached to the top of the pump, to which a nozzle and a drain hose are connected. In most cases, the pump fails due to foreign objects entering the system.SM Samsung pump


If there are coins, wrappers, small toys, etc. in the pockets of the clothes loaded into the drum, all this can be found in a drain pipe. Because of this, not only the filter and hoses are clogged, but also the pump itself. The trash filter is installed in the cochlea, which is attached to the pump. As you can see, these three elements are very closely interconnected.

Plastic tank and metal drum

A plastic tank is an important part of the washing machine, it is in it that water is collected and mixed with detergents here. Care must be taken that the tank does not lose complete tightness. Otherwise, a water leak may begin, which is difficult to eliminate.

The drum is made of metal and is located inside the tank. Mistresses lay clothes in it. As you noticed, the surface of the drum is corrugated, this is necessary for better washing off contaminated tissues. Also, the drum is equipped with plastic combs (ribs), which allow you to scatter the laundry inside, ensuring the penetration of a mixture of water and detergents.

On different models of Samsung brand cars, the drums have a different volume and, accordingly, different maximum load of laundry.

Hoses, nozzles and powder collector

The detergent dispenser (dispenser) is designed to store laundry detergent, conditioner until they are fed into the tank. The powder receiver has a smart device and does not allow simultaneous contact with the tank of detergents for various purposes. At the beginning of washing, the dispenser delivers the powder, and at the rinsing stage, the conditioner.

drain hose and nozzles

Drain and inlet hoses are important components of the unit. They are necessary for the timely intake of water in the tank and the discharge of waste fluid. In addition to hoses, it is worth talking about the nozzles, they are located inside the case and serve to transport water in the system.

The washing machine is quite complicated, and the first time it may seem that it is simply unrealistic to understand the layout and the principle of operation of each particular part. But if you study this issue well and completely immerse yourself in it, you can of course deal with it.
