The situation is when, after starting the washing program on the control panel of your Indesit All indicators begin to flash randomly, often causing panic among owners of household appliances. This behavior of the machine signals that the electronic control module has entered emergency mode, recording a serious malfunction in the operation of one of the key components. Instead of performing a normal cycle, smart electronics block the start to prevent further damage or flooding of the room.
It is worth noting that all lights flashing - this is not a random glitch, but a special diagnostic signal implemented by the brand’s engineers. Unlike the blinking of one specific button indicating a local problem (for example, a lack of drainage), having all the LEDs working at the same time requires a deeper analysis of the state of the electrical circuit. This often indicates problems with the engine or tachometer, but other possibilities cannot be ruled out.
Before calling a technician, you need to conduct initial visual diagnostics and try to perform the system reboot procedure. In some cases, the cause is a simple power surge or a software failure of the controller. However, if the symptom persists after restarting, then there is a physical problem with the system that requires attention.
Diagnostics of tachometer and engine
The most common reason why washing machines Indesit all the indicators light up, there is a malfunction of the tachometer or a problem with the electric motor itself. A tachometer is a small magnet with a coil that controls the speed of rotation of the drum. If the control module does not receive a signal from it, it “does not understand” whether the motor is spinning and blocks operation to prevent the drum from accelerating to critical speeds.
Often the problem lies in a slipped or burst tachometer coil. During intensive washing, especially during spinning, vibration can dislodge this element. In such cases, the motor may hum and try to start, but the drum will remain motionless, and the control panel will go into error indication mode. Less common is wear on the motor brushes, which also leads to loss of contact and a similar system response.
⚠️ Attention: If you hear a strong hum from the motor when you try to start, but the drum does not rotate, immediately unplug the device. Prolonged operation of the engine in a blocked state can lead to overheating and melting of the wiring.
To check, you need to get to the engine by removing the rear housing cover. Visually inspect the tachometer mount: it should sit tightly on the motor shaft. If the coil is loose or misaligned, it must be put back in place. If there are no visual defects, you will need to ring the windings with a multimeter to exclude an interturn short circuit.
Checking the electronic control module
The second most likely candidate for breakdown is the electronic module. The control board is the “brain” of the washing machine, and if it fails, the consequences can be varied. The blinking of all indicators often indicates a breakdown of the triac that controls the motor, or a breakdown of contacts in the cables connecting the board to other components.
Moisture is the main enemy of electronics. Even if you did not fill the machine from above, condensation or microscopic splashes during washing could get on the contacts. Oxidation of the tracks on the board leads to chaotic behavior of the LEDs. It’s also worth checking the connectors: sometimes they just come loose due to vibration, and it’s enough to reconnect them for the system to work.
If you have the skills to work with a soldering iron, you can remove the board and inspect it for swollen capacitors or burnt marks. However, repairing a module is a delicate job that requires special knowledge. It is often cheaper and more reliable to replace a burnt element or entire board than to try to restore tracks in makeshift conditions.
Can I wash it by hand?
Manual switching of programs when all indicators are on is usually impossible, since the module blocks any commands. An attempt to start the cycle with the “Start” button will only lead to a repetition of the error light indication.
Malfunctions of the water heating system
Although less common, it happens that the cause of emergency mode is a heating element (tubular electric heater). If the heating element penetrates the housing or has a short circuit, the control module detects a critical error in the power circuit. In this case, the machine may even begin to draw water, but before heating begins it will go into protection, which will be signaled by flashing lights.
Diagnostics of the heating element is carried out using a multimeter in resistance measurement mode. Normal resistance of a working heater for a car Indesit usually around 20–30 ohms. If the device shows one (open) or zero (short circuit), the element must be replaced. It is also important to check that there is no breakdown on the housing by measuring the resistance between the contacts of the heating element and the metal tube.
Pay attention to the condition of the wiring going to the heater. Often the insulation melts or the terminal contacts burn due to poor clamping. This creates a high contact resistance, which the module interprets as a fault. In such cases, replacing the contacts and stripping the terminals can solve the problem without purchasing new parts.
When replacing the heating element, always change the rubber gasket. Old rubber loses its elasticity after compression and may allow water to pass through when reinstalled.
The program crashes and requires a reboot
Sometimes technique Indesit is behaving strangely due to a software glitch caused by a power surge or static electricity. In this case, the physical nodes may be healthy, but the controller is stuck in an error state. The first step in any flashing light situation should be to try to “reset” the device.
To perform a full reset, you need to disconnect the washing machine from the power supply not just with the power button, but by removing the plug from the socket. Leave the equipment alone for 15–20 minutes. This time is necessary for the capacitors on the control board to discharge and the temporary data from the controller’s RAM to be erased.
After a pause, turn on the machine and try running any program. If the indicators stop flashing and the cycle begins, then the problem was a one-time problem. If the situation repeats, it means there is a hardware error and requires repair. Don't ignore repeated failures, as they may be a sign of more serious problems.
Disconnecting from the network for 20 minutes is the easiest and free way to rule out a software failure before starting complex diagnostics.
Indesit Error Code Table
Although all lamps flashing is a general signal, on some models a flashing sequence or combination of lights may indicate a specific component. Below is a table that helps decipher the behavior of indicators in various diagnostic modes.
| Symptom | Probable Cause | Actions |
|---|---|---|
| All indicators are flashing | Tachometer, motor, module | Checking the tacho coil and motor brushes |
| The lock indicator is flashing | Problem with hatch locking | Replacing UBL (hatch blocking device) |
| Temperature indicator flashes | Malfunction of heating element or sensor | Ring the heater and thermostat |
| The spin indicator is flashing | Problems with draining water | Cleaning the filter and checking the pump |
It is important to understand that diagnostics using indicators does not always provide a 100% guarantee of identifying a breakdown. Electronics of modern cars Indesit is designed so that the same error can be coded differently depending on the year of manufacture and series. Therefore, the table serves as a guide and not as a final diagnosis.
Procedure when a malfunction is detected
If you encounter the problem described, act consistently so as not to worsen the situation. Chaotic pressing of buttons or repeated turning on and off without a pause can completely “kill” the control module. Follow the algorithm that minimizes risks.
First, make sure the network voltage is stable. If the light in the house “jumps”, use a stabilizer. Then follow the reset procedure described above. If this does not help, proceed to a visual inspection of the internal components, after first turning off the power to the device.
☑️ Primary diagnostic algorithm
When disassembling the machine, carefully monitor the integrity of fragile plastic elements and connectors. Any careless movement can break the case latches or damage the wiring, which will add new problems to the existing fault.
When you need to call a specialist
Self-repair is only possible if you have basic knowledge of electrical engineering and tools. If you don’t know how to use a multimeter, don’t know the difference between phase and zero, or are afraid to disassemble equipment, it’s better not to take risks. Unskilled intervention often leads to higher repair costs.
Calling a specialist is required if an electronic module needs to be replaced or complex re-soldering of board components is required. A technician is also needed if the problem lies in the engine itself and requires it to be overhauled or replaced, which is difficult to do in the tight space of the washing machine.
⚠️ Attention: By opening the washing machine body, you lose the manufacturer's warranty. If the warranty period has not yet expired, any independent intervention will deprive you of the right to free repairs.
A professional diagnostician will be able to accurately determine the cause of the blinking lamps in 15–20 minutes, using special equipment. This will save you time and money that could be spent on purchasing unnecessary spare parts at random.
How much does diagnostics cost?
The cost of diagnostics is often included in the cost of repairs if the client agrees. If you refuse repairs, the repairman has the right to charge only for the visit and inspection, which is usually cheaper than buying a new part.
Preventing future breakdowns
To Indesit washing machine served for a long time and pleased with its stable operation, it is important to follow the operating rules. Regularly clean the drain pump filter of debris, lint and small objects. Blockages create additional stress on the pump and can indirectly affect the operation of the electronics.
Use only high-quality detergents designed for automatic washing machines. Excess foam can get on the sensors and cause false alarms of the protection system. It is also recommended to check the condition of hoses and connections for leaks every six months.
Do not overload the drum beyond the limits specified in the instructions. Overload leads to rapid wear of the bearings, stretching of the cuff and increased load on the engine, which ultimately can cause failure of the tachometer - the main reason for the blinking of all lamps.
Regular maintenance and careful operation increase the service life of the washing machine by one and a half to two times, postponing the need for expensive repairs.
What should I do if, after replacing the tachometer, the lights continue to blink?
If replacing the tachometer coil does not help, the problem may be deeper. Perhaps the motor itself is faulty (wear of the commutator or windings), or the cable connecting the motor to the board is damaged. It is also worth checking the condition of the graphite brushes - if they are worn out, the motor will not start and the module will generate an error. In rare cases, flashing or replacement of the control module itself is required.
Can I continue washing if all the indicators are flashing?
It is strictly not recommended to operate the equipment in this condition. The machine is in emergency mode, and further attempts to start may lead to combustion of the electronic module or motor. In addition, there is a risk of flooding if the hatch locks or valves do not work correctly.
How long does it take to repair such a problem?
If the reason is the tachometer or brushes, repairs take 1 to 2 hours along with diagnostics. If it is necessary to replace the control module or motor, the time may increase to 3-4 hours, especially if it is necessary to find and deliver rare spare parts for a specific model Indesit.
Why does the machine flash only during the spin cycle?
Flashing during the spin phase most often indicates an imbalance of the drum or problems with the motor. The system cannot reach the required speed for the centrifuge due to a malfunction of the tachometer or wear of the brushes, which causes an emergency stop and an error indication.
