No equipment will work forever, which is why all Indesit washing machines break down over time. If the device is still under warranty, then you should not unscrew anything and look at it yourself, as this may invalidate the documents for free service.
When the warranty period has expired, in order to save on the services of a technician, you can try to fix the problem yourself. Do-it-yourself repair of an Indesit washing machine begins with diagnosing the device, localizing the problem area and step-by-step elimination of breakdowns that may occur in this unit. The article will be useful to everyone who has the necessary tools and skills to handle them, which will help save the family budget.
Let's list the main elements
The washing machine device includes both main and additional modules. Your unit will only work if all components are in smooth contact with each other. A car of any model contains:
- electric motor;
- tank and drum;
- drain pump;
- control panel with electrical module support;
- spring shock absorbers;
- special unit with bearings;
- the main body, the rear wall of which is made in the form of a hatch cover;
- liquid intake valve;
- tubular electric heater and parts for it.
Please note that this is a completely basic set of parts for any washing device. If you understand what and how the circuit works, you can easily analyze the behavior of your Indesit washing machine.
What is the structure of the electronic unit?
The solution in this case may be the ability to connect Samsung equipment not directly, but through a stabilizer. The progress of filling the loading tank with water is carried out gradually and is also regulated electronically.
Repair of a thyristor unit Repair of this unit should be carried out only after checking for faulty capacitors.
In the instructions for the equipment, the manufacturer gives several recommendations in case the machine does not turn on: It is necessary to check the connection network and the integrity of the wire; Check that the inlet hose is connected correctly; Make sure the door is closed tightly; It is also necessary to pay attention to the parameters of the selected washing program, the absence of a wash delay.
What may indicate a malfunction and subsequent repair of the circuit board in the washing machine: SMA displays an error code on the display. From the second anode A2 of this triac, the signal arrives through a resistive voltage divider to the pin. Naturally, such modules will not work, since they must first be loaded with firmware files corresponding to certain SM models. The winding diagram can also be found on the Internet.

The water overheats or does not heat up, which does not correspond to the selected mode. Indesites-Aristons, there are also about five boards lying around, with Electrolux and Zanusi processors, very rarely in the sense of which I could not repair - There is only one LG Electrolux board in my home collection - There is not a single one that I could not repair, despite the inconvenience of repair.
Indesit-Ariston, there are also about five boards lying around, with the processors. The diagram of the control module of a Samsung, Ariston, Indesit or other popular brands of washing machine allows you to understand the sequence of connections of the circuit components and the functions of each component. Any person, even those far from physics, can understand this scheme.
About the mechanism as a whole
After this, you can mount a new trigger. It is easy to eliminate such troubles if the protection systems prevented an accident. The capacitor is always soldered only to the positive electrode in the block.
General information A distinctive feature of the VEKO SM electronic modules under consideration is that, despite the various functionality of the SM, their “electronic filling” undergoes almost no changes with the exception of the external components of the electronic module as part of the SM. It is worth noting that some manufacturers strive to completely eliminate this problem. Any person, even those far from physics, can understand this scheme.

How does the technology work?
The Indesit washing machine is equipped with a plastic tank. To avoid deformation of the tank, it is not so rigidly connected to the body so that excessive vibrations are not created, which destroy the tank. After all, the tank moves very actively during washing and, especially, spinning, but the body remains motionless, which actually ensures the safety of the tank. Plus, two shock absorbers are placed below for support, and springs are placed on top.
During washing, the drum rotates thanks to a special pulley to which it is connected through a cross. The pulley, in turn, receives revolutions transmitted by the electric motor through a belt drive. All these actions cause the pulley to rotate, and since it is attached to the drum, the drum also rotates, due to which our clothes are washed. The drum itself is built inside the tank with a mount.
The so-called “intelligence center” of the washing machine is the control board; it is it that sets the sequence of operations and the coordinated interaction of all components of the unit. For example, supplying a washing machine with water includes a number of actions of different parts: the inlet valve draws water from the water supply, the heating element heats it to the required temperature, the pressure switch controls the volume of water, and a special pump removes contaminated water after the washing process is completed.
Now you can roughly imagine how your washing machine works and how it works, but to add more details, you should look at the operation of each module separately.
Considering the design of an LG washing machine with direct drive
LG direct drive washing machines are considered the best in the modern technology world. However, not everyone understands what its difference is from the design of other modern technology, and how important it is.
The use of direct drive reduced the number of parts and improved the balance of the drum
The main element of each washing machine design is the drive.
If previously the work was carried out using a belt, then in modern LG washing machines there is a technology that completely eliminates bringing the drum into an active state with a belt. The entire structure transmits forces to the rotor through air gaps. The motor itself is connected to the drum, this avoids links and wear on the elements that move. To prove the reliability of its work, LG guarantees the operation of its washing machines for up to 10 years.
Main container and drum
Drums are predominantly made of stainless steel, as are the tubs of some washing machines. This material is more durable and, as a result, your machine will last much longer. However, if you prefer a more budget-friendly and lightweight option, take a machine with a plastic tank. It is not as durable, but it is cheaper and easier to carry. In the most common models, the tank is located horizontally, although some manufacturers also produce machines with inclined tanks.
All modern Indesit washing machines are equipped with plastic tanks.
So, the tank is the main capacity of any washing machine. As we already understood, there is a built-in drum into which you load your laundry. The drum usually has a huge number of holes through which water from the tank penetrates into this container. Yes, water is drawn from the water supply into the tank, where it is heated and mixed with the powder, and enters the drum during the washing process. In addition, the surface of the metal tank is very corrugated, which improves the quality of washing. To avoid leaks and other troubles, no foreign objects should get into the tank.
Heating the mixture of water and powder
A tubular electric heater, or abbreviated as a heating element, which is built into the lower part of the machine, is responsible for heating the water in the tank. When the washing machine is actively used, the heating element is subject to the greatest damage, because scale forms on its surface, which gradually disables it, and, in addition, the heating elements always fail faster than other electrical appliances. The more often you wash in hot water, the faster problems will arise with the heater.
According to the technical characteristics, it is worth saying that the energy consumption is approximately 1800-2200 W. This is equal to the average energy consumption of any heating mechanism. Therefore, if it seems to you that the washing machine “eats” a lot of energy, then the problem is clearly with the heating element.
Call the master
If you are unable to fix the sensor failure yourself, call a specialist. You can find them on Avito; many craftsmen offer their services at home, and they charge less than employees of official service centers.
To avoid running into a scammer or an unscrupulous professional, read reviews from people who have already used the services. If this is a worthwhile specialist, his profile will definitely have reviews from grateful clients.
The price for private services is discussed individually. In equipment repair companies, replacing a pressure switch costs from 1,600 rubles. Do not pay for the service in advance to avoid becoming a victim of an attacker.
The specialist must have with him instruments that will help identify a malfunction of the pressure switch. If everything is fine with it, the technician will determine what the problem really is.
What makes the drum move?
Remember we already talked about the connection between the drum, pulley and electric motor? It is the electric motor that powers the device. Indesit uses commutator motors in order to save money and, as a result, to reduce the cost of goods. However, commutator motors do not have any enviable strength, and in addition, they are very susceptible to voltage drops, so it is better to connect them through a stabilizer.
Brushed motors quickly lose their level of functionality, and eventually stop working altogether if they are not carefully maintained (you will have to, for example, change the brushes regularly).
Water supply and removal
Water is supplied from the water supply to the tank according to this scheme.
- A specialized module “orders” the intake valve to open;
- The valve opens, and since it is under high pressure, water immediately begins to penetrate into the tank.
- The pressure switch controls the volume of water so that exactly as much as is needed (the same happens when draining water, so this sensor is indispensable for any machine);
- When the required volume has been reached, the pressure switch signals the module, and it, in turn, signals the valve that there is enough water and needs to close.
- The valve closes and the water supply stops.
As soon as the wash is completed, the control module begins to interact with the pump. The pump receives a signal to drain water and begins to push it into the sewer through the drain hose. Thus, water is pumped out from the tank. Then, using the same operations, the machine draws in water to rinse the laundry, and then drains it in the same way.
The drain pump is faulty
Symptoms: The water takes too long to drain or the water does not drain at all.
If all possible blockages in the drain system have been checked and eliminated (drain filter, hose, pipes, sewer), then the cause of poor drainage is most likely the drain pump (pump).
The pump usually fails as a result of prolonged use and clogging: if cleaning the pump does not help, then it will have to be replaced. We advise you not to try to repair the pump yourself: this work requires thorough disassembly of the washing machine and diagnostics, in addition, finding a suitable replacement model is very difficult.
The “brain” of the washer
The control board is responsible for all parts of the machine, except for the control panel (it includes all the buttons, indicators, etc.). There is a separate fee for this. Both of these devices are combined and perform the function of the “intelligence” of the machine: they issue commands to the modules for the coordinated operation of the device.
Washing programs and modes are pre-designed algorithms for certain actions that are recorded on the control board. Accordingly, it is responsible for the operation of any program that you choose. The board structure consists of many semiconductor elements (these include triacs, thyristors and other parts).
Contacts between parts are made through special electrically conductive tracks, which are also located on the control board.
The control panel board has a slightly different purpose. While the control board coordinates the interaction of parts, this one coordinates the interaction between the operator and the control board. That is, its task is to “explain” to the control board what exactly the user wants to do, as well as inform him about all the details of the wash (by displaying information on a special screen or through indicators).
Auxiliary elements
We have figured out how the basic parts of the Indesit washing machine work. However, there are many more. Their role is not so fundamental, but without them your washing will not happen either. Here is their list.
- Parts that prevent the harmful effects of vibration on the tank are springs and shock absorbers. They dampen vibration.
- To prevent water from flowing out from under the hatch cover, there is a special cuff. This is a kind of rubber seal that tightly seals the hatch when washing.
- Hatch blocking device - abbreviated as UBL. This detail also helps to completely close the hatch and prevent accidental or independent opening. As long as the UBL is in good working order, water will not pour out of the machine.
- Drive belt. The one that directs the rotation to the pulley, and the pulley, as you remember, helps rotate the drum. Therefore, for the drum to operate, you cannot do without this part.
- Counterweights. Counterweights are very large stones, both in volume and weight, that are installed inside the body, increasing its mass. Due to these parts, the machine has the ability to resist centrifugal force during spinning. Otherwise, the washing machine would move very actively around the room due to pressure on the side walls.
- Hatch door. There is no need to describe the significance of this detail. Without it, washing is basically impossible.
- Powder receiver. There you place detergent and conditioner, which are dosed into the tank during the washing process. As a rule, it includes three compartments for different types of detergents.
- Pipes. Through them, water moves into and out of the tank. Built into the body.
Now, knowing all the details of the operation of the Indesit washing machine and the features of its design, you can easily analyze its behavior and condition. If a problem occurs, you will know what to look for first, and you will probably be able to carry out simple repairs yourself. Remember that if you treat it with care, your device will last you much longer and will delight you with its quality much more.
