The Electrolux range of boilers is characterized by a relatively high performance of equipment that can operate at low room temperatures. The main advantage of such boilers is high efficiency.
The protection system fully controls the health of all processes, blocking the gas supply in the presence of malfunctions. Despite the many advantages, this gas equipment cannot constantly work without breakdowns. All malfunctions are shown on the display in the form of a code, the description of which helps in finding and eliminating the problem.

The most common errors, their manifestations and solutions
If the boiler has not been serviced for a long time, as required by the manufacturer, then there are risks that after 3-4 years the first troubles will arise. The situation is aggravated by power surges in the network, as well as blockages in the chimney that prevent the removal of combustion products.
E1
On different models of boilers, this error can be displayed in different ways: 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.
- Changing the angle of the electrode in the burner, which may be a factory defect or its deliberate removal when setting up the equipment during the installation of the heating system.
- Clogging of the electrode with soot, which interferes with its normal operation.
- Lack of reliable contact between the electrode and the wire.
- Gas valve malfunctions.
- 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 attenuation of the boiler. There will be difficulties with ignition, the boiler will turn off immediately after the appearance of the flame.
It can be difficult to fix the problem yourself if cause is a broken part. The user of gas equipment needs to check the presence of gas in the system, as well as its supply to the boiler (whether the valve is closed). After that, press the "Reset" button and check the operation of the boiler. The rest of the diagnostics and repairs will be carried out by specialists.
Do not try to clear the error code by permanently restarting the boiler. It may help at first, but the problem will not go away. Be sure to consult with specialists and conduct unscheduled diagnostics.
E2
This error, which is labeled as e02 in some models, 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 airtight, but during operation, air can enter, which is released from the water. It warms up faster than water, respectively, the radiators will boil at relatively low rates on the boiler.
- Lack of the required water level in the system - if the water supply tap is closed or in the expansion tank, where water must be poured on its own, the level has dropped sharply.
- Boiler pressure drop - if the mark drops to 1 bar, then you need to check the tightness of the system itself. It is possible that there is a leak in some radiators or at the joints, due to which the pressure does not hold at the desired level.
- Thermostat failure – sudden power surges can lead to its inadequate operation. The sensor may need to be replaced with a new one.
- Pump not working - there are two possible reasons: either there is no electricity, or the minimum operating mode is set on the pump. If it is used improperly, the device fails, due to which the water stops circulating in the system, and heats up exclusively in the boiler, causing it to overheat and emergency shutdown.
In Electrolux boilers, problems with the pump are quite common, 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 bleed nuts on each - part of the water with oxygen bubbles should come out. The procedure should be performed exclusively 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 the system is automatically replenished.
- Check radiators and joints for leaks if the system is constantly pressure drops.
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 enters the room.
There are several reasons for this:
- Blockage in the chimney - these can be the remains of burning and soot, and in the winter season - frost and icicles. You need to look into the chimney and check the draft level. If it is weak, then you should call the stove-maker, who will clean the ventilation duct.
- Gas control sensor malfunction - gives a false signal that blocks the operation of the entire boiler.
- The supply draft in the room is broken - when 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 - less often, but it happens that this error appears for no apparent reason, when the light was turned off abruptly and then turned on. Automation is under increased load, with which it cannot cope.
To fix the problem you need:
- 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 restarting the boiler.
- Call the masters, if nothing helps, so that they conduct a comprehensive diagnosis and eliminate the identified cause.
If there is frost 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.
E4
This error code indicates a sharp decrease in pressure in the circuit. May also be referred to as 04.
Occurs for the following reasons:
- Water from the circuit went into the plumbing - it is appropriate if the make-up tap is not closed and the water in the general water supply has been turned off.
- Scale contamination of the heat exchanger - happens when using tap water saturated with oxygen, as well as when the boiler is operated 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, make up for the deficiency if necessary, and also look for a leak. If all this does not help, then you should call the masters. Perhaps the cause is a malfunction of the pressure gauge or problems in the board.
E5
Occurs if the pressure on the pressure gauge rises rapidly and shows critically high marks.
The reasons may be the following:
- Malfunction or airiness of the expansion tank - in those models where the expansion tank is mounted directly into the boiler itself.
- Clogged safety valve - when using low-quality water, as well as a large amount of scale and rust, which clog the small cells of the filter grid.
- Malfunction of the pressure sensor - a short circuit or open circuit is possible.
It is impossible to diagnose this problem on your own. You should call in specialists who can check all possible causes and eliminate them. If this error is detected on the display, it is imperative to turn off the boiler and shut off the gas supply. It is extremely dangerous to use gas equipment that shows critical values \u200b\u200bin the heating system.
E9
The error code signals a critically low coolant temperature 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 has dropped to 0 degrees. In an apartment, this error is less common than in private homes.
Atypical error codes and their causes
Electrolux manufactures quality boilers that are easy to operate and easy to maintain. Getting them out of action is a lot of work. But there are cases that cause rare malfunctions. You need to know about them.
E6
Malfunction of the hot water control sensor, which happens after 10-12 years of boiler operation. The cause is usually the oxide of the compounds, which you can either try to clean or completely replace the sensor with a new one.
Also, the board itself can give an E6 error. This happens when there is a power outage in the network. You can try to restart the boiler with the "Reset" button. If this does not help, call the masters.
I01
This error can appear both independently and paired with errors E5 and E6. Indicates contamination of the heating medium, which is causing damage to the heater. The problem is solved by dismantling and cleaning it with the help of special tools.
In some models, it is possible to pour the 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.
E7
The problem lies in the violation of the thermostat. Often the cause is a break in the cable, which is easy to determine by “ringing” it along its entire length. Again, the work is only available to specialists. The user can only turn off the equipment and wait for the wizards by indicating the error code.
General Tips and Tricks
Not always error codes appear in the presence of a particular breakdown.
Be sure to check the following points:
- Is the gas turned on (is the supply valve open) or is there any gas in the system at all?
- Is there water in the heating system and is its level sufficient? The standards are specified in the technical operation manual.
- Is the chimney clogged and is there ventilation in the room where the boiler is located?
- Is the pump functioning? Is there heating of heating radiators after switching on the boiler?
- Is the boiler plugged in?
For some, this seems ridiculous, but a third of all wizard calls occur precisely because of the user's inattention.
To reduce the risk of a serious breakdown, you must follow 2 important rules:
- Every year, check the serviceability of gas equipment and clean the water heating element from scale.
- Call specialists as soon as a malfunction occurs or an error is displayed on the scoreboard.
This will save the boiler from costly repairs, and your life from a possible threat.
Questions and answers
In this case, it is better to call specialists, since there are a lot of reasons for overheating of the coolant, and this is not necessarily the airiness of the heating system.
The most obvious reason lies in the airiness of the system. In theory this shouldn't happen, but in practice it does happen.It is necessary to alternately drain a little water from each radiator and add a new portion to the expansion tank.
Such an error may also indicate the creation of reverse thrust if your chimney is not installed correctly or there is no deflector. It is better to call a stove-maker and a gas equipment master, 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 adverse conditions. Breakdowns and malfunctions are marked with codes that indicate the need for repair of a particular part. The instruction manual contains all the decodings inherent in a particular boiler model. Repairs and maintenance are carried out exclusively by masters who have the appropriate permission.
