Е1

Depending on the boiler model, this error may appear differently on 01, e01, or E1.

Regardless, the following are the root of the issue:

• No gas supply to the boiler or insufficient gas level to support the combustion process in the boiler.
• Changing the angle of inclination of the electrode in the burner, which may be a factory defect or deliberate pushing it away when setting up the equipment during installation of the heating system.
• The electrode is clogged with soot, which prevents it from working properly.

• Lack of reliable contact between the electrode and the wire.
• Gas valve malfunction.
• Problems in the central control board, which inadequately evaluates the processes and provokes an emergency shutdown of the boiler.

One way that these issues may show up is a spontaneous boiler fade-out. Having trouble starting, the boiler will extinguish as soon as a flame appears.

If a broken part is the cause, it may be challenging to solve the issue on your own. When using gas equipment, the operator should make sure that gas is present in the system and that the boiler is receiving it (that is, that the valve is not blocked). Next, push the "Reset" button to verify that the boiler is operating properly. Specialists will handle the remaining diagnostics and repairs.

Avoid restarting the boiler repeatedly in an attempt to clear the error code. It might be helpful at first, but the issue won’t get better. Always seek professional advice and perform an ad hoc diagnostic test.

Е2

This error, which appears as an e02 on some models, is a result of the coolant overheating. This overheating causes a reverse temperature differential in the system, which in turn overheats the boiler and triggers an emergency shutdown.

Possible causes include:

• Blowing out of the heating radiators – the heating system is airtight, but during operation air can get in, which is released from the water. It heats up faster than water, respectively radiators will boil at relatively low values on the boiler.
• Lack of proper water level in the system – if the water supply tap is closed or in the expansion tank, where the water should be poured independently, the level has dropped sharply.
• Pressure drop on the boiler – If the level drops to 1 bar, the system itself must be checked for leaks. There may be a leak in some of the radiators or joints, causing the pressure to not hold at the correct level.

• Thermostat malfunction – sudden voltage spikes can lead to its inadequate operation. It may be necessary to replace the sensor with a new one.
• Pump does not work – there are two possible causes: either there is no electricity or the pump is set to minimum operation mode. If it is used incorrectly, the device malfunctions, because of which the water stops circulating in the system, and is heated exclusively in the boiler, causing its overheating and emergency shutdown.

Pump issues, more especially stator issues, are fairly common in Electrolux boilers. It will need to be completely replaced in certain models because it cannot be fixed.

The following methods can be used to remove this error:

1. Check if the radiators are leaking by opening the drain nuts on each radiator – some of the water with oxygen bubbles should come out. The procedure should be performed only when the pump is on, otherwise it will simply be ineffective.
2. Fill up the water in the expansion tank if its level is below the required level. Opening of the water supply valve during automatic system make-up.
3. Check radiators and joints for leaks if the system pressure is constantly dropping.

It is advisable to leave everything in the hands of gas experts when evaluating the pump and thermostat. It is not advisable to tamper with the boiler’s operation on your own because the results might be highly unpredictable.

Е3

This error, which appears on all boilers with the same label, denotes issues with the smoke exhaust when the flue gas is not released outside as it should and either stays in the combustion chamber or seeps into the adjacent space.

This is due to a few factors:

• Blockage in the chimney – This can be caused by residues of carbon monoxide and soot, and in winter by ice and icicles. It is necessary to look into the chimney and check the draught level. If it is weak, it is necessary to call a furnace technician, who will clean the ventilation channel.
• Failure of the gas control sensor – gives a false signal, which blocks the operation of the whole boiler.

• The supply draught in the room is disturbed – 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 – Rarely, but it happens that this error appears for no apparent reason, when the light was abruptly turned off and then turned it on. The automation is experiencing an increased load that it cannot cope with.

It’s essential to solve the issue:

1. Check the draught in the chimney by putting a burning match to the hood. If the flame does not move, there is a clog and it needs to be cleaned out.
2. Open a window or door to the room and try to restart the boiler.
3. Call the masters, if nothing helps, so that they carry out a comprehensive diagnosis and eliminate the identified cause.

It is important to remove any ice that may be inside the chimney (parapet boilers) carefully. If this is the result of the boiler being left unattended for an extended period of time, it is started at the lowest speed and then slowly warmed up.

Е4

A significant drop in circuit pressure is indicated by the error’s code. It might also suggest 04.

Occurs for the reasons listed below:

1. Water from the circuit has gone into the water supply – is appropriate if the make-up tap is not closed and the water in the common water supply has been turned off.
2. Contamination of the heat exchanger with limescale – Happens 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 the scale on the heat exchanger.
3. Leakage of the heating system – Leakage in radiators or at joints.

When error E4 arises, the system must be checked for leaks, the required water level must be present, and any necessary adjustments must be made. If none of this was helpful, you ought to give the masters a call. This might be the result of a circuit board issue or a malfunctioning pressure gauge.

Е5

Occurs when the pressure gauge experiences a sharp rise in values, approaching critical levels.

The following could be the causes:

1. Faulty or inflated expansion tank – in those models where the expansion tank is mounted directly into the boiler itself.
2. Clogging of the safety valve – when using poor quality water, as well as a large amount of scale and rust, which clog the small cells of the filter grid.
3. Faulty pressure sensor – possibly short-circuited or open circuit.

This is not a problem that you can diagnose yourself. It is imperative to contact experts who can investigate and rule out any potential causes. Make sure to turn off the boiler and cut off the gas supply if the display indicates this error. Utilizing gas equipment that displays critical values in the heating system is exceedingly risky.

Е9

The error code alerts the user to the system’s coolant being dangerously low and susceptible to resizing. This occurs when the room temperature falls to zero degrees Celsius and the boiler is not used for an extended period of time. This mistake is less frequent in apartments than in homes.

It makes sense to empty the water from the system if you have to leave and decide to turn off the heating while there is a severe frost outside. Asking a friend to keep an eye on the house is simpler than having to rewarm it from scratch later.

Atypical error codes and their causes

High-quality boilers that are simple to use and maintain are produced by Electrolux. You have to work hard to get them out of order. However, some situations result in uncommon malfunctions. It is essential to be aware of them.

Е6

After operating a boiler for ten to twelve years, the hot water control sensor may malfunction. Compound oxide is typically the cause; you can either try cleaning the sensor or replace it entirely with a new one.

Error E6 can also be produced by the board itself. This occurs when there are network power fluctuations. Using the "Reset" button, you can attempt to reset the boiler. If none of this works, contact the professionals.

I01

This error may occur alone or in conjunction with errors E5 and E6. shows that the coolant is contaminated, which is the cause of the heater’s problems. By disassembling it and using specialized tools for cleaning, the issue is resolved.

Certain models allow you to add cleaner to the system and then drain it after a set amount of time. Only a specialist performs all manipulations. Dismantling without the necessary knowledge and expertise is strictly prohibited.

Е7

The thermostat isn’t working properly, which is the issue. It is frequently the result of a cable break, which is easily identified by "dialing" the entire length of the cable. Once more, only specialists are able to access this work. The only thing the user can do is unplug the devices and watch for the masters to signal the error code.

General tips and recommendations

Not every breakdown results in the appearance of error codes.

Make sure to look for things like these:

1. Is the gas on (whether the supply valve is open) and is it in the system at all??
2. Whether the water in the heating system is running and the water level is adequate? The standards are specified in the technical operation manual.
3. Whether the flue is not blocked and whether the room where the boiler is located is ventilated?
4. Is the pump functioning? Is there heating radiators after turning on the boiler?
5. Whether the boiler is plugged in?

While this may sound absurd to some, user inattention accounts for one-third of all service calls.

There are two key guidelines that must be adhered to in order to lower the likelihood of a major breakdown:

1. Every year to check the serviceability of the gas equipment and clean the water heating element from limescale.
2. Call a specialist as soon as a fault appears or an error is displayed on the display.

This will protect your life from potential danger and spare the boiler from expensive repairs.

Questions and Answers

I occasionally notice the E2 error. When you force a reboot, everything vanishes. A few days later, everything proceeds according to the same plan. How should one proceed?

Since there are numerous reasons for coolant overheating and a blown heating system is not always the cause, it is best to contact experts in this situation.

As soon as I increase the boiler output, I frequently see the E2 error flashing on the boiler. What could it be connected to?

A blockage in the system is the most evident cause. Although this shouldn’t happen in theory, it can in reality. It is required to periodically empty a small amount of water from each radiator and replenish the expansion tank.

Demonstrates my ventilation issues, but I try to carry a match because the draught is unbearable. What is the reason behind it?

If your chimney was installed incorrectly or has a missing baffle, this error may also be a sign of a back draft. As there is always a chance that the board itself will malfunction, it is preferable to call a furnace technician and a master on gas equipment.
