The Electrolux line of boilers is characterized by relatively high performance equipment that can operate at low room temperatures. The main advantage of such boilers is their high efficiency.
The protection system fully monitors the health of all processes, blocking the gas supply in the presence of malfunctions. Despite many advantages, this gas equipment cannot constantly operate without breakdowns. All faults are displayed on the display in the form of a code, the description of which helps in finding and fixing the problem.
E1
On different boiler models, this error may be displayed differently: 01, e01, E1.
In any case, the problem lies in the following:
- Lack of gas supply to the boiler or its insufficient level to maintain the combustion process in the boiler.
- A change in the angle of inclination of the electrode in the burner, which may be a factory defect or intentionally moving it away when setting up the equipment during installation of the heating system.
- The electrode is clogged with soot, which interferes with its normal operation.
- Lack of reliable contact between the electrode and the wire.
- Gas valve malfunction.
- Problems in the central control board, which inadequately evaluates processes and provokes an emergency shutdown of the boiler.
These problems can manifest themselves in the form of spontaneous extinguishing of the boiler. There will be difficulties with ignition, the boiler will go out immediately after the flame appears.
It can be difficult to fix the problem yourself if the cause is broken parts. The user of gas equipment needs to check the presence of gas in the system, as well as its supply to the boiler (if the valve is closed). After this, press the “Reset” button and check the operation of the boiler. The rest of the diagnostics and repairs will be performed by specialists.
Do not try to clear the error code by constantly restarting the boiler. This may help at first, but the problem will not go away. Be sure to consult with specialists and conduct unscheduled diagnostics.
Error in water supply to the system/coolant overheating
It is strictly recommended to connect heating boilers through a stabilizer (for the boiler) or a UPS; this will save you from unnecessary costs for replacing the control board.
The make-up valve is located at the bottom of the heating installation, next to the connection pipe for the cold water pipe.
It opens counterclockwise until the characteristic noise of the incoming liquid appears; do not forget to close the tap in the reverse order, otherwise the pressure will creep into the reverse red zone and the relief valve will begin to operate (water will flow).
Turn over the pump without igniting the boiler. Press and hold the button: mode (for Ariston Egis Plus 24 series for 10 seconds), Reset (for modifications UNO, Matis for 6 seconds). The rotation of the pump impeller initiates the removal of accumulated bubbles from the coolant.
Check automatic valves installed in the heating system. For complete guarantee, bleed manually, since the air exhaust channel in the fittings regularly becomes clogged with low quality fluid and requires cleaning. After these steps, error 105 should disappear.
Ideally, an automatic air vent should be installed in at least 1-2 batteries on each floor.
Also, do not forget that the pump has 3 speeds and if an error appears when the pump is turned on, you need to increase the speed, for example from 1 to 2 or immediately to 3, if after these manipulations the error does not appear, then the reason is in the pump.
Any diagnostics and repair of the boiler must be carried out by a certified specialist with a valid certificate issued by Rostekhnadzor.

E2
This error, which in some models is marked as e02, indicates overheating of the coolant, which creates a reverse temperature difference in the system and, in turn, overheats the boiler itself, causing an emergency shutdown.
The reasons may be:
- Airiness of heating radiators - the heating system is sealed, but during operation air may enter, which is released from the water. It warms up faster than water, so the radiators will boil at relatively low boiler temperatures.
- Lack of the required water level in the system - if the water supply tap is closed or in the expansion tank, where water should be filled independently, the level has dropped sharply.
- Decrease in pressure on the boiler - if the mark drops to 1 bar, then you need to check the tightness of the system itself. There may be a leak in some radiators or at the joints, which is why the pressure is not maintained at the desired level.
- Thermostat malfunction - sudden voltage surges can lead to its inadequate operation. The sensor may need to be replaced with a new one.
- The pump does not work - there are two possible reasons: either there is no electricity, or the pump is set to the minimum operating mode. If it is used incorrectly, the device fails, as a result of which water stops circulating in the system, and is heated exclusively in the boiler, causing it to overheat and emergency shutdown.
In Electrolux boilers, problems with the pump occur quite often, or rather with the stator. In some models it cannot be repaired, so a complete replacement will be required.
You can resolve this error in the following ways:
- Check the airiness of the batteries by slightly opening the drain nuts on each - some of the water with oxygen bubbles should come out. The procedure should be performed only with the pump turned on, otherwise it will simply be ineffective.
- Add water to the expansion tank if its level is below the required level. Open the water supply valve when automatically recharging the system.
- Check radiators and joints for leaks if pressure in the system constantly drops.

As for assessing the quality of the pump and thermostat, it is better to entrust everything to specialists in gas equipment. It is not recommended to interfere with the operation of the boiler yourself, since the consequences can be very unpredictable.
Error E4 boiler Electrolux 1
Modern gas heating units are complex devices, and their repair is the prerogative of a professional. But is it always necessary to call a specialist? The article will help you understand the reasons for the E4 error in the Electrolux boiler and give recommendations for troubleshooting.
Recommendation. The search for any malfunction should begin by pressing the REZET button (on the instrument panel, next to the display). Imported boilers are sensitive to the quality of the supply voltage. The instructions for Electrolux indicate the required value: 230 (±10%) V. With surges or a lower rating, the automation may produce a false signal and an error appears. But if it does not reset, you need to deal with the reason.
Malfunction code e4 is interpreted in the documentation as a decrease in pressure in the circuit above the permissible value. But professionals know: a boiler error also appears in cases where, after turning on the pump, the pressure in the system rises by no more than 0.2 bar. The electronic circuit does not record this minimal difference (difference), but perceives it as a lack of flow (circulation) of the coolant, and error e4 is displayed on the Electrolux display.
Knowing this, it becomes clear where the problem may be and where to start.
E3
This error is marked the same on all boilers and indicates problems with smoke removal, when the exhaust gas is not discharged outside as it should be, but remains in the combustion chamber or penetrates into the room.
There are several reasons for this:
- A blockage in the chimney can be the remains of burning and soot, and in the winter season - ice and icicles. You need to look into the chimney and check the draft level. If it is weak, then you should call a stove technician who will clean the ventilation duct.
- A malfunction of the gas control sensor gives a false signal that blocks the operation of the entire boiler.
- The supply draft in the room is disrupted - when the windows and doors are tightly closed, and there is no ventilation duct in the room itself. Often occurs in apartments where the chimney is clogged.
- Problems with the electronic board are less common, but it happens that this error appears for no apparent reason when the light is suddenly turned off and then turned on. The automation is under increased load, which it cannot cope with.
To fix the problem you need to:
- Check the draft in the chimney by holding a burning match to the hood. If the flame does not move, then there is a blockage and you need to clean it.
- Open a window or door to the room and try to restart the boiler.
- Call the experts if all else fails, so that they can conduct a comprehensive diagnosis and eliminate the identified cause.
If there is ice inside the chimney (parapet boilers), it should be carefully removed. If this happened due to prolonged non-use of the boiler, then it is started at minimum speed, after which it is gradually warmed up.
E 03
Electrolux boiler error E3
The error indicates that the smoke removal system is not operating correctly. Mainly due to a narrowing of the diameter of the canal or its blockage. This could be caused by foliage, or a bird caught in the pipe - checking the draft and cleaning it is not difficult.
Recommendation : the appearance of a code during the initial startup of the boiler is caused by errors in calculations (wrong length, diameter), an illiterate diagram or a violation of the chimney installation technology. The same thing applies if the code is displayed periodically when the wind direction changes. We will have to correct the mistakes made.
E4
This error code indicates a sharp decrease in pressure in the circuit. May also be designated 04.
Occurs for the following reasons:
- Water from the circuit has gone into the water supply system - this is appropriate if the make-up tap is not closed and the water in the general water supply has been turned off.
- Contamination of the heat exchanger with scale occurs when using tap water saturated with oxygen, as well as when operating the boiler at maximum temperatures. The preceding factor is the lack of annual preventive cleaning, which completely dissolves scale on the heat exchanger.
- Depressurization of the heating system - leaks in radiators or at joints.
When error E4 appears, it is necessary to check the presence of the required water level in the system, fill the deficiency if necessary, and also look for a leak. If all this does not help, then you should call the experts. The cause may be a faulty pressure gauge or a problem with the board.
E 02
Electrolux boiler error E2
The error indicates a sharp increase in temperature in the circuit (overheating). This happens when the rate of fluid circulation decreases or the channel is blocked. The Electrolux boiler is not always to blame - troubleshooting should begin with diagnosing the heating system.
Probable Causes
Recommendation : a good owner always has a backup heat source at hand (an alternative to a boiler). The optimal solution is to remove the heat exchange device and send it to a workshop: maintenance will take no more than 3 days. It’s better not to do it on your own, following advice from the Internet. The internal part of the product has a complex configuration, and we are not talking about a perfectly smooth surface. Just clean it and put it in Electrolux - delay the appearance of the error for two to three weeks. The technology of competent maintenance involves stage-by-stage processing of the heat exchanger: pouring a special reagent/holding (to soften deposits)/rinsing under pressure. Can't do it at home.
If the measures taken do not help eliminate the error, you need to change the thermostat of the extract air circuit. In all Electrolux boilers, its function is performed by a thermal resistance. A regular continuity check for a break does not give the true picture: the defect may be an interturn short circuit - only replacement.
E5
Occurs when the pressure on the pressure gauge rises rapidly and shows critically high levels.
The reasons may be the following:
- Failure or airiness of the expansion tank - in those models where the expansion tank is mounted directly into the boiler itself.
- The safety valve is clogged when using low-quality water, as well as a large amount of scale and rust, which clog the small cells of the filtration grid.
- Pressure sensor malfunction - possible short circuit or break.
It is impossible to diagnose this problem yourself. You should call specialists who can check all possible causes and eliminate them. If this error is detected on the display, you must turn off the boiler and shut off the gas supply. Using gas equipment that displays critical values in a heating system is extremely dangerous.
E9
The error code signals a critically low temperature of the coolant in the system, which is fraught with freezing. This happens when the boiler has not been used for a long time, and the temperature in the room drops to 0 degrees. In an apartment this error is less common than in private houses.
Expert opinion
Grebnev Vadim Savelievich
Heating system installer
If you need to leave, and you decide to turn off the heating, and it’s severely cold outside, it makes sense to drain the water from the system. It’s easier to ask someone you know to look after the house than to then warm it up from scratch.
E 09
Electrolux boiler error E9
An error is generated by the anti-freeze system. Happens when the water in the pipes cools down (t 0 < +2).
Probable Causes
Recommendation : when installing an Electrolux boiler in an unheated room, raise the temperature with another heater. If, when the value reaches +5, the boiler does not start, call a specialist.
E6
Malfunction of the hot water control sensor, which happens after 10-12 years of operation of the boiler. The cause is usually oxide compounds, which you can either try to clean or completely replace the sensor with a new one.
The board itself can also give an E6 error. This happens when there is a power outage in the network. You can try to reboot the boiler using the “Reset” button. If this does not help, call the experts.
I01
This error can appear either independently or in combination with errors E5 and E6. Indicates contamination of the coolant, which is causing the heater to suffer. The problem is solved by dismantling and cleaning it using special means.
Some models have the ability to pour a cleaner into the system and drain it after a certain time. All manipulations are performed only by a specialist. Dismantling without skill and experience is strictly prohibited.
General tips and tricks
Error codes do not always appear when there is a particular breakdown.
Be sure to check these points:
- Is the gas turned on (is the supply valve open) and is there any gas in the system at all?
- Is water supplied to the heating system and is its level sufficient? The standards are specified in the technical operation manual.
- Is the chimney duct clogged and is there adequate ventilation in the room where the boiler is located?
- Is the pump functioning? Do the heating radiators heat up after turning on the boiler?
- Is the boiler plugged in?
For some, this seems funny, but a third of all calls to technicians occur precisely because of the user’s carelessness.
To reduce the risk of serious damage, you must follow 2 important rules:
- Every year, monitor the serviceability of gas equipment and clean the water heating element from scale.
- Call specialists immediately as soon as a malfunction appears or an error appears on the display.
This will protect the boiler from costly repairs, and your life from possible danger.
Malfunctions and error codes of Electrolux boilers: typical and atypical, solutions
The Electrolux line of boilers is characterized by relatively high performance equipment that can operate at low room temperatures.
The main advantage of such boilers is their high efficiency. The protection system fully monitors the health of all processes, blocking the gas supply in the presence of malfunctions. Despite many advantages, this gas equipment cannot constantly operate without breakdowns.

Questions and answers
Sometimes I see error E2 appear. I do a forced reboot and everything disappears. A few days later everything follows the same scenario. What to do?
In this case, it is better to call specialists, since there are many reasons for overheating of the coolant, and this is not necessarily airiness in the heating system.
I often see error E2 flashing on the boiler as soon as I increase the boiler power. With what it can be connected?
The most obvious reason lies in the airiness of the system. In theory this shouldn’t happen, but in practice this happens. You need to drain a little water from each radiator one by one and add a new portion to the expansion tank.
It shows that I have problems with ventilation, but I try to bring a match - the craving is crazy. What is the reason?
Such an error may also indicate the creation of reverse draft if your chimney is installed incorrectly or there is no deflector. It is better to call a stove-maker and a gas equipment specialist, as there is always a risk of malfunctions in the board itself.
In conclusion, it is worth noting that Electrolux gas boilers have excellent characteristics and cope with their work in the most unfavorable conditions. Breakdowns and malfunctions are marked with codes that indicate the need for repair of a particular part. The instruction manual contains all the explanations specific to a particular boiler model. Repairs and maintenance are carried out exclusively by specialists who have the appropriate permit.
Other faults
On Electrolux 24 Basic Space Duo devices, error f4 may appear if the circulation pump is faulty. The code appears if, after 30 seconds from the moment the pump starts, the pressure has not increased by 0.1 bar. Check the operation of the pump; if it malfunctions, purchase a new one.
Error l01
This means that the heat exchanger is clogged. Remove it and descale it according to the instructions for the device.
Code E7
Appears when a malfunction occurs in the coolant thermostat. In this case, measure the resistance of the thermostat and see if the sensor wires are disconnected or oxidized. If the problem is in the wires, strip and connect the wires; if the sensor is faulty, replace it. If the sensor is OK, check the electronic board.
Thermostat
If noise occurs when the boiler beeps, you should check the system for airiness, the operation of the fan and pump.
If the room does not heat up when the boiler is running, check whether the heating tap is closed, the condition of the dirt filter, rinse it if necessary, check whether the heating circuit is airy.
