When in the washing machine Indesit All the indicators flash at the same time, this is a direct signal that the electronics have recorded a critical malfunction of one of the nodes. This behavior of the control panel is typical for series models WISN, W105TX, IWSB And many others that don’t have a digital display. Instead of outputting the error code, the device uses the flashing rhythm of the light bulbs to tell the user to stop the washing cycle and conduct a diagnosis. Ignoring this signal or attempting to continue operating may cause serious damage to the engine or control module.
Unlike the screen models, here diagnostics is performed by counting blinks or analyzing a combination of burning indicators. Often owners confuse the lock mode from children with a technical breakdown, but in the case of simultaneous flashing of all lamps, it is a failure in the self-diagnosis system. The protection mechanism works if the sensors detect deviations from normal operating parameters, whether it is a voltage surge, overheating or a leakproof tank.
The first thing to do is to record which indicators are active and with what frequency they give a signal. In some cases, the blinking occurs cyclically, in others it burns with constant light after turning on. Proper signal decoding will avoid unnecessary replacement of expensive parts and determine exactly whether a wizard call is required or the problem can be solved by cleaning the filters or checking the wiring.
The main causes of electronic failure
The most common reason for the fact that Indesit flashing all the light bulbs, is a voltage surge in the household network. The control module is extremely sensitive to drops, and with a sharp change in the parameters of the current, the electronics go into protective mode. In such a situation, the system blocks the start of programs to prevent failure. TEN. Or the engine. If your home is often experiencing power outages, it is recommended to install a voltage stabilizer.
The second common problem is the failure of the control module itself. The chips can burn out due to moisture that got inside the case, or because of the factory soldering marriage. Sometimes the contacts are oxidized and the signal simply does not reach the indicators correctly, causing chaotic blinking. Visual inspection of the board often helps to identify burned elements or traces of corrosion.
⚠️ Warning: Before any inspection of internal components, be sure to disconnect the washing machine from the power grid. Working with electrical circuits under voltage is deadly.
It is also worth considering the possibility of sensors that transmit incorrect data to the processor. If pressostat (water level sensor) or thermostat give erroneous readings, the machine can not start the cycle and signals about it in all available ways. Diagnosing these elements requires the use of a multimeter to check resistance.
If after a power surge the machine stopped responding to the buttons, try to completely turn it off for 15-20 minutes. This will help to reset an error in the module memory if it is not related to physical damage.
Deciphering error codes through flashing
Manufacturer Indesit I put into the diagnostic system the ability to display specific error codes through the flashing of indicators. Even if all the lamps are on, it is often possible to notice that one of them flashes in a particular rhythm or in combination with the others. For example, a series of quick blinks may indicate a water dialing problem, and rare flashes may indicate a drain. Understanding this logic is critical to repair.
To accurately determine the fault, it is necessary to start the diagnostic mode or carefully monitor the behavior of the machine at the time of inclusion. Often, the error code can be counted by paying attention to which indicator lights up first or flashes differently than the others. Below is a table of correspondence of symptoms and possible malfunctions.
| Blinking symptom | Probable cause | Action required |
|---|---|---|
| Blink all the indicators at once | Voltage surge, module software failure | Reboot, network check |
| Blinking lock and temperature indicator | Problem with TEN or thermostat | Multimeter TENS invertebrating |
| Squeeze-indicators flashing | Failure of the engine or the tachodilator | Checking brushes and contacts |
| Indicators flash cyclically | Flush system clog | Filter cleaning and pipe |
It is important to note that in different models Indesit The combinations may differ. For example, in the series W105TX The codes can be read by the number of flashes of the start delay indicator, while other models use a combination of buttons. Always check the technical documentation of a specific modification.
Diagnosis of engine and tachodilator
If all the light bulbs blink when trying to start the wash, there is a high probability of a problem with the engine. The electronics do not receive a signal about the rotation of the drum and blocks the program. Most often, graphite brushes fail, which are erased over time and lose contact with the collector. This is a classic malfunction for cars with a mileage of more than 5-7 years.
To check, it is necessary to remove the back cover of the case and visually assess the condition of the brushes. If they are less than 1.5 cm long, replacement is required. It is also worth checking the tachodaknik - a small element that is attached to the engine and reads the revolutions. If it has moved away or damaged, the control module “thinks” the motor is not working.
- 🔌 Turn off the power and remove the drive belt for free rotation of the drum.
- 🔧 Dismant the engine by disconnecting the wires and fasteners.
- 👁️ Examine the collector for the presence of coarseness and check the integrity of the winding.
- 🧹 Clean the contacts and install new brushes if necessary.
⚠️ Note: When installing new brushes, be sure to rub them to the collector, otherwise sparkling contact and rapid wear are possible.
After replacing the parts, assemble the design in reverse order and start the test wash. If the blinking stops and the drum spins, the problem is solved. Otherwise, a more thorough diagnosis of the motor’s electrical circuit will be required.
Problems with the water heating system
Another group of malfunctions that cause chaotic blinking is associated with water heating. If TAEN (Tube electric heater) is covered with scale, it can overheat and shorten the body. The temperature sensor detects the anomaly and gives an emergency stop signal. In some cases, a breakdown of the TEN leads to a voltage emission on the control module.
The heating element should be checked with a visual inspection. If cracks or swelling are visible on the surface, the part should be replaced immediately. You also need to check the resistance between the contacts and the body – it should be infinite. The presence of resistance indicates a breakdown in isolation.
How to check the TEN without a multimeter
Turn the car on to washing mode at 90 degrees. If after 10-15 minutes the glass of the hatch remains cold, and the water does not warm, most likely, the TENG has burned. However, this method is not accurate and does not replace instrumental diagnostics.
Often, the thermostat also fails together with the TEN. This small sensor is inserted into the heater body or located nearby. Its task is to turn off the heating when a given temperature is reached. If the thermostat is “stuck” in the open state, the water will not warm up, and the machine will give an error.
Blockages and drain problems
Disturbance of water circulation can also cause Indesit It flashes all the indicators. If the water cannot escape from the tank, the pressostat does not give a signal about the release of the container, and the program freezes. Most often, a drain filter located in the bottom of the car behind the decorative panel is clogged.
For cleaning, you need to substitute a flat container, twist the filter and remove the accumulated debris: coins, threads, pile. It is also worth checking the corrugated pipe going from the tank to the pump, and the impeller of the pump itself. Sometimes a small object gets into the pump, which blocks the rotation.
☑️ Checklist of the drain system checklist
If the filter is clean but the water is worth it, the drain pump itself may be faulty. Check if there is a voltage on it when you turn on the “Plum” mode. The absence of motor buzzing in the presence of voltage indicates its combustion. In this case, a replacement of the node is required.
Error reset and test run
After the physical malfunction is fixed, the error must be reset from the memory of the control module. In many models Indesit It is enough to turn off the car with a button and pull the plug from the socket for 15-20 minutes. Once enabled, the error should disappear if the cause has been eliminated.
To check the performance, start the fast washing or rinsing mode. Pay attention to the water set, heating and pressing. If the car has passed a full cycle without flashing lamps and extraneous sounds, the repair can be considered successful. If the error is repeated, the diagnosis will have to continue.
- 🚿 Start a short program without laundry.
- 👂 Listen to the engine and pump.
- 🌡️ Check the water heating with your hands through the hatch glass.
- 🌀 Make sure the squeezing is going well.
⚠️ Note: If the error returns after the parts are replaced, the problem may be in the wiring or the control module itself, which requires professional repair or flashing.
Regular maintenance of the washing machine, including cleaning filters and using scale products, significantly reduces the risk of such failures. Keep track of the equipment and it will last for many years.
The main reason for the flashing of all lamps is a failure in self-diagnosis due to a voltage surge or a sensor malfunction. The exact code can be found by observing the rhythm of blinking.
Frequently Asked Questions (FAQ)
Can I continue to wash if all the lights are flashing?
No, it is absolutely impossible to continue washing. This can lead to flooding of the apartment, engine failure or even fire wiring. The car needs to be turned off and diagnosed.
How much does it cost to repair the Indesit control module?
The cost depends on the complexity of the breakdown. Replacing a burned-out element can be inexpensive, while a complete replacement of the board or reflashing the processor will cost much more. The exact price will be called by the master after the diagnosis.
Why does the error occur only when the water is heated?
This indicates a malfunction of the TEN or thermostat. When the heating is turned on, a surge in current or short circuit occurs, which the module perceives as a critical error.
How to enter service mode on Indesit?
On most models, you need to turn the selector at 6 hours, then press the combination of buttons (usually "Temperature" and "Additional rinse") and turn the selector clockwise to the end.
