Button that starts processes

After successfully diagnosing the power cord and FPS, we move on to the dashboard. The fact is that on Atlant washing machines, when one or more keys stick, a failure occurs, after which the entire system is de-energized. While modern washing machines can withstand such a shock and display a corresponding error on the display, older models cannot cope with the load and simply “go silent.”

To understand whether the problem is caused by a stuck key, you need to perform several steps:

• open the detergent tray and, pulling it towards you, remove it from the housing;
• Unscrew all the screws holding the dashboard;
• carefully disconnect the panel from the machine (you don’t need to completely unhook the board - you just need to gain access to the “internals”);
• switch the multimeter to resistance mode;
• Apply the probes to the button contacts and measure the resistance.

Practice shows that sticking of the “Start” button more often leads to an emergency shutdown of the machine. If it works, then there is a problem with the other keys being used. We check everything sequentially. If sticking keys has nothing to do with it, then there is a high probability that the problem is in the electronic module. Here it is better to turn to specialists.

If the indicators light up, burn randomly or go out

The Indesit washing machine may start, but not work, not only because the lock does not turn on, but also due to other malfunctions, for example, a system failure. In this case, the lamps blink randomly or light up and immediately go out. You need to disconnect the machine from the network and wait a few minutes; if this does not help, open the instruction manual and look in it for information about performing a system reset.

In some cases, erratic blinking of light bulbs may occur due to wiring problems. It burns out or the connectors become loose due to constant vibration. It is necessary to carefully inspect the wires and then test them with a multimeter. Damaged elements are replaced with new ones. Usually you can talk about a wiring fault if the machine blinks and does not turn on.

If the lights blink in a certain sequence, this means that the machine has completed a self-diagnosis program and is reporting some kind of breakdown. To decipher the code, you need to open the user manual, it contains detailed information.

What to do?

If, after turning on the Indesit or Samsung washing machine, the user finds that the lock icon is on, do not be upset. Experts recommend doing the following:

• Disconnect the device from the power supply.
• Check the cleanliness of the lock and, if necessary, remove small debris.
• Restart the unit.
• If the indicator continues to blink, call a repair technician.

How to recognize a breakdown in equipment?

Complaints that the SMA does not turn on have a variety of manifestations that can accompany such a problem:

• when you press the “Start” button, the unit does not give any signals;
• after switching on, only one indicator blinks, and nothing else works;
• after an unsuccessful startup attempt, all light indicators light up and flash at once.

Sometimes the machine clicks and crackles, but the motor does not work, which means the drum does not rotate, water does not fill, and the SMA does not begin to erase. If you have made sure that current flows freely into the washing machine, then you need to take a number of measurements. They will allow you to identify the cause of failure of internal elements.

Failure to start washing is often due to a broken “On” button. A similar problem is common in the latest SMA models, in which current is supplied from the power cord directly to the button. In order to diagnose the serviceability of an element, you need to perform a number of simple steps:

• disconnect equipment from the power supply;
• raise the top panel of the unit;
• disconnect the control unit on which the button is located;
• disconnect the connection section of the wiring and buttons;
• connect a multimeter and calculate the supply of electric current in the on mode.

If the button is working properly, the device produces a corresponding sound.

If the equipment turns on and the light indicators on it light up, but the washing does not start, it is likely that the hatch is blocked. Most often, the SMA blocks the door at the start of the program

If this does not happen, then you should pay close attention to this node. To do this, you need to disassemble the front part of the SMA housing and then use a special tester to measure the voltage supply. If monitoring confirms that electrical current is flowing, but the device does not work, you will need to replace it

If monitoring confirms that electrical current is flowing, but the device does not work, you will need to replace it.

If the mechanism indicates a lack of voltage, then perhaps the problem is related to the failure of the command device or the working electronic unit.

Any unit has a special element responsible for suppressing electromagnetic radiation during operation - it is called an interference filter. This part protects the SMA from electrical waves that can render it inoperative. If the filter breaks, the machine will not be able to turn on - the indicators in this case do not light up.

Many SMAs are designed in such a way that the internal wires are in close contact, so if the equipment vibrates strongly, they can tear and fall out of the socket. In order to determine the area of ​​damage, you should completely disassemble the MCA and use special testers.

Another common reason for no washing is a faulty electronic board. Its functionality is usually checked only after the accuracy of the connection of all operating microcircuits has been established, and the absence of damage to the wiring, plug, and also the mechanism responsible for locking the hatch door.

If the washing machine stops starting after a power surge, then the first thing you need to do is check the power supply filter - it prevents the electronic board from burning out and very often suffers itself if there is a fault in the electrical network.

This check is quite simple to carry out. To do this, you need to unscrew all the mounting bolts from the back panel and remove it, then find the surge protector (usually it is located on the side), and then carefully inspect all the wires and contacts leading to it. If you notice burnt out elements or a swollen filter, they will have to be replaced. If the problem cannot be detected, you need to test the contacts with a multimeter.

If the check does not produce any results and the network connection is working, then you should proceed to diagnostics of the command device. You will have to disassemble this element into the smallest parts and carefully inspect them. To do this you need to perform several steps:

• remove the command device and disassemble it;
• by pressing the latches located on the sides, you need to open the cover and remove the board;
• The board should be carefully inspected for burning, and then use a multimeter to measure the resistance at the contacts.

After this, all that remains is to make sure that there is no debris or foreign particles, visually determine the integrity of the working elements, if necessary, treat them with alcohol and reassemble them in the reverse order.

How to fix the error yourself

Before proceeding with active steps, read the instructions supplied with the unit. It must contain a troubleshooting section that lists symptoms and/or error codes, as well as possible solutions. If the actions described in the instructions turned out to be useless or the instructions are completely lost, read our recommendations - perhaps they will help you understand how to fix the problem that has arisen in your washing machine.

There are several standard situations when the washing machine does not turn on, and several or all indicators on its body light up or flash alternately. Let's look at the most common of them.

If the buttons on the washing machine continue to blink and you cannot fix the problem yourself, most likely there is a breakdown. In this case, you cannot do without a professional washing machine repair technician.

Hardware disable lock

If the machine has already finished washing, but still does not remove the lock, then you will have to turn off the key on the display yourself. This is not difficult to do: just hold down the “Start/Start” button for 5-6 seconds. Holding down the power key should restart the system and reset all settings. After this, the UBL turns off and the light stops lighting.

There is a more drastic way:

• disconnect the washing machine from the power supply by unplugging the cord from the outlet;
• wait 10-20 minutes;
• restart the machine.

This is an emergency reboot of the system, during which all previously specified settings are reset. Such a restart is necessary when the washing machine does not respond to button presses.

If the reboot does not work, and when the system starts, the key lights up again, then a breakdown has occurred. It is necessary to check the door mechanism and test the UBL with the control board.

The washing machine blinks all the lights, but does not turn on

Lack of response to user commands, and the inclusion of all indicators and buttons indicates the presence of a technical malfunction - the control board is broken. This component fails due to power surges. Short circuits become a catalyst for capacitor burnout. If you know how to use a soldering iron, you can change them yourself.

Sometimes only the lock indicator lights up, but the machine still does not turn on. Make sure parental controls are deactivated. You may have turned on the child lock, so the buttons do not work. If only certain lights come on, for example, the service button indicator, then you need to disassemble the washing machine to check the serviceability of the following components:

— the electric heater (heater) burned out;

— there were problems with the pump;

— failure of the electronic motor;

— failure of the sensor transmitting commands.

It is necessary to identify the damaged node and restore its functionality. Modern washing machines are sensitive to overload because they are equipped with a special sensor that weighs the laundry before starting washing. To restart the cycle, open the door and arrange the clothes evenly or remove some of the laundry.

Description of the situation

Often, the user is faced with a situation in which the indicator light blinks, but the washing process does not start. Or the work process has started, the rinsing stage begins, but the unit randomly changes the washing process and selects an inappropriate temperature mode. However, if the device is disconnected from the power supply and then turned back on, the situation does not change.

Starting the washing machine

Note that this situation often occurs when operating washing machines of the following brands:

• Indesit.
• Samsung.
• Bosch.
• LG.

But one should not assume that this is due to the poor quality of these machines. It’s just that in units of other brands this type of breakdown is displayed on the display using a letter code.

For beneficiaries We continue the series of articles on repairing washing machines with our own hands. All Indesit witl 106, witl 86, witl 1067, witl 867 models are similar to each other and the repair problems are the same.

Washing machines can be assembled on an ARCADIA or EVO-II electronic board

This depends on your CMA product number.

Deciphering the error code by flashing indicators:

By adding the numbers corresponding to the blinking LEDs, you will receive an error code.

As an example of error F10, we add the sum 8+2=10 (F10).

Faults by error code (EVO-II board):

We have already published in a previous article how to troubleshoot a fault on the EVO-II board of WISL models by error code. They are similar to each other.

Faults by error code (ARCADIA board):

This board is the newest of all, it replaced the EVO-II. Installed since 2007. Schematic connection of the Arcadia control board with end devices

1. Anti-interference filter (power capacitor) 2. Heating element 3. Pump (pump) 4. Door locking device 5. Tachogenerator 6. Motor stator 7. Electric motor rotor 8. Main wash water intake solenoid valve 9. Pre-wash solenoid valve 10. NTC (temperature) sensor 13. Water level switch (pressostat) 14. Linear water level switch

When the machine does not display an error code:

— When plugged in, the door immediately locks (a click is heard) and the hatch lock indicator light comes on. Suspicion of a breakdown of the motor triac, burnout of the resistance, or short circuit of the motor.

It is necessary to remove the top cover by unscrewing the screws:

Visually inspect the board by unscrewing the fasteners:

Next, we use a tester to call the engine block (6 wires, 2 of which are red - tacho, and 4 black are divided in pairs: rotor and stator):

— Frequent malfunctions are associated with the engine. It is a collector type.

For example, after pressing the start button, the hatch lock is activated and “silence” occurs. In many cases, brush wear can be determined by external inspection or by the intensity of sparking on the engine commutator: both under load (there is laundry in the machine tank) and without it - in this case, abundant sparks occur (not along the entire perimeter of the commutator).

If the brushes wear out significantly, there is a loss of engine power - for example, if the drum of the washing machine does not “turn” with the laundry loaded into it.

Engine control circuit via tachogenerator (ARCADIA module):

— It takes an infinitely long time to wash, constantly filling and draining water.

It is necessary to properly organize the drainage system. The tip of the hose should be at a height of 60 to 100 cm.

In addition, a break in the stream must be ensured when draining to avoid water being sucked back into the SM.

-All indicators flash, except for the pre-rinse, main and rinse.

The hero of the occasion is the control unit (module), namely the switching power supply in it. An incorrect signal (voltage) is sent to the board and the lights blink.

Where is this module located:

With front loading, it is located under the tank on the rear side. In the vertical racks under the top control cover.

What to look for in the power supply is the swollen capacitors C17, C16, C20. We select new capacitors, maybe 1000 uF. We take a soldering iron and change

Major breakdowns

Let us repeat once again - in such a technically complex Indesit device there are things that can break and it is not always possible to cope with breakdowns on your own. But again, repairs do not always end in the workshop. Perhaps such strange behavior of the device as:

• the device began to work unstably;
• the detector lights on the control panel light up in a chaotic manner;
• if the display shows errors whose names begin with F;
• there are traces of leaks;
• there is a strong smell of burning wiring or smoke appears.

If this is noticed, then it’s time to pay serious attention to your home assistant and call a specialist for an examination. And the probable causes of breakdowns can be seen from the table

Ten often causes problems with the washing machine

Rare reasons for all lights to blink

The visual information system sometimes works for other reasons. Sometimes confusion arises, so first you need to accurately determine the malfunction:

• involuntary drainage of water;
• burnout of the heating element for water and drying;
• motor failure;
• breakdown of the drain pump, etc.

If the washing machine is not working, the indicators will flash accordingly.

The heating element becomes coated with scale over time, causing increased wear. The motor can break down due to worn brushes or entangled hair and fur. The control device fails much less often; usually the cause is burnt contacts.

Check error codes according to Indesit instructions. Accurate diagnostics make it easy to repair the washing machine without major financial investments.

Interference filter (FPS): meaning and performance check

The control module, electric motor and other parts create radio frequency waves when the washing machine is running, which can harm other household appliances located near the machine. To protect electrical devices, the machine is equipped with an interference filter. If it malfunctions, it will create an obstacle to the passage of electric current. This will be the reason why the automatic machine does not start the washing process. To check the functionality of this part, you need to diagnose the wires at the input and output, as well as the device itself using a tester. If the FPS does not work, you need to order a new filter from the service center or make a request for its replacement.

Preparing for fault diagnosis

If such a situation occurs with an Indesit machine, the first thing we do is disconnect it from the network, and do not open the hatch. First, use the button on the panel, then disconnect the cord from the outlet. Cover the floor around with towels and rags, place a container underneath the drain filter, like a scoop or container, and only then open it. The plug opens counterclockwise; if it is screwed tightly, use pliers. After all the water has drained, you can clean the drum from the laundry.

After all the operations, it is worth understanding at what point the drum stopped rotating. The chronology of work will help to establish the exact reason for its stop. If a failure occurs during the spin cycle, and the laundry is damp but not soapy, then you need to check the selected washing mode. If the delicate wash is turned on or the “no spin” function is active, then this small misunderstanding can be easily corrected. The water does not drain due to a blockage in the drain system, and therefore spinning does not occur. Also, stopping the drum’s operation may be due to an overload of things, due to which an imbalance has occurred. Problems with the pressure switch or control module lead to failures during the washing process. Expressed in burnt out wiring or errors in the control module.

Engine

If the washing machine motor is faulty, water may get into the drum. It is necessary to check the following motor elements:

• wiring;
• slats;
• brushes.

When there is standing water in the drum, it is first drained through a surge filter and the equipment is disconnected from the electrical network. Certain steps must be taken to remove the engine:

• The screws are unscrewed from the panel at the back.
• The panel is removed (you can see the motor under the tank).
• The wiring is disconnected.
• The fasteners are unscrewed and the engine is pulled out.

If the brushes are worn out, they are replaced. The lamellas are also changed or turned on a lathe. The wiring is checked and replaced if necessary.
