In detail: do-it-yourself baxi main 24 fi repair from a real master for the site my.housecope.com.
Italian gas boilers Baxi occupy a solid place in the heating equipment market due to their high efficiency, stable operation. even in adverse conditions and thoughtful stylish design ... But, despite their high reliability, sometimes in the work of Baksi boilers malfunctions occur caused by violation of operating conditions or failure of individual elements of the boiler. Most often, you can eliminate them yourself, without resorting to calling specialists.
The Baksi line of gas boilers includes a number of models that differ in volume, type of installation, and functionality. Moreover, the principle of their work is generally similar.
The most popular boiler models:
Baxi Luna
Baxi Slim
Baxi Main four
Baxi Main 24 fi (Baxi Mine 24 fi);
Baxi Nuvola
Baxi EKO four
By installation type gas boilers are divided into wall and floor.
Wall heater fixed using special brackets in any convenient place, which makes wall models very popular. Closed-chamber chambers such as the Baxi Main 24 fi offer increased efficiency and environmental friendliness in a small footprint.
Coolant volume in the heat exchanger depends on the model, in the most powerful it reaches 80 liters . By functionality model can be single-circuit - for heating, or double-circuit - in addition to the heating system, they also supply the DHW circuit.
Work they can both on natural gas and liquefied , from cylinders, which makes it possible to install them in non-gasified areas. Boilers completely volatile and require an AC voltage connection.

The principle of operation of gas heating equipment:
The sensors analyze the temperature in the room, and when the minimum value is reached, they give a signal to turn on the circulation pump.
The pump turns on, creating a vacuum in the return pipe, while the heated water enters the heating system.
The microprocessor gives a signal to ignite the burner at low power, it gradually increases, and the coolant heats up to the temperature set by the user.
Further, the boiler operates in modulation mode - it maintains the temperature within the specified limits, turning on when it drops.
At any of these stages, a malfunction may occur, which the boiler notifies with the help of coded errors. .
Possible malfunctions of the boiler Baxi Main for, Baxi Main 24 fi, Baxi Eco for:
the burner goes out immediately after switching on or during heating (error codes e01, e04);
the boiler cannot be ignited;
overheating occurs (error code e02);
the water pressure in the system drops (error code e10);
extraneous noise is heard in the work;
pops occur in the combustion chamber;
the coolant does not heat up to the set temperature;
one of the sensors fails (different error codes may appear).
The most common reasons for the appearance of certain malfunctions, according to the specialists of the service centers, can be:
improper installation of the heating system;
errors when connecting the boiler to the mains;
water ingress on the board, into the burner or into the electrical part of the boiler;
poor quality of network water or other heat carrier;
a sharp drop in gas pressure;
the mains voltage drops or inadmissibly increases.
The resulting malfunctions can be easily eliminated by adjusting the boiler, but sometimes it is necessary to call a specialist to replace the boiler parts.
If you are not confident in your skills in setting up gas equipment, it is better to contact a service center.Improperly performed repairs can lead to complete failure of the boiler!
When an error code appears on the boiler display, it is necessary to determine the malfunction according to the classifier attached to the operation manual ... Codes, as a rule, indicate a number of malfunctions, therefore, in addition, it will be necessary to check the condition of the components and assemblies of the boiler. Some breakdowns can be fixed on your own, how to do this is described below.
This malfunction occurs when phase-dependent boilers, for example, Baxi Main or Baxi Main 24 fi, are incorrectly connected to the mains: if the "phase" and "zero" are reversed, the boiler operation is impossible due to the accumulation of air in the system. With this malfunction, an error e01 appears on the boiler display, and the coolant pressure drops.
make the correct connection of the "phase" and "zero";
bleed air from the system;
add coolant;
turn on the boiler and make sure that the e01 error has disappeared.
The "phase" can be determined using the color coding of the cable cores. If the installation is made with a single-color wire, or you doubt its correctness, then you must use a voltage indicator.
This situation is possible in several cases: when the pressure in the heating system is incorrectly set, as well as when the diode bridge or the valve responsible for the gas supply is faulty. The e01 error also appears on the scoreboard.
If the matter is in the settings, they can be corrected, guided by the instructions of the documentation for the boiler. In the event of a malfunction of the components, it may be necessary to replace them.
Error e01 is displayed on the board. The most common reason is low gas pressure in the line or incorrect setting of its lower limit. If the gas pressure is unstable and constantly drops, it is better to set the lower value to around 5 mbar.
Error e03 signals serious problems that can lead to boiler breakdown. You can fix it yourself, the reason may be:
incorrectly mounted smoke exhaust system;
faulty fan;
inadmissible narrowing of chimney pipes;
the appearance of condensation in the chimney;
faulty pneumorel;
lack of electrical contact between the board and the relay or the board and the fan.
In models with a closed combustion chamber, for example, Baxi Main 24 fi, the cause of the error e03 may be an incorrect parameter setting F-43.
Another malfunction that occurs when the gas valve is incorrectly set, the minimum and maximum gas pressure limits. It must be adjusted according to the instructions in the instruction manual.
Most often it occurs when the burner control board or the gas supply valve fails. Testing is required, replacement of the board, sometimes together with the valve.
Video: instructions for replacing the board in Baxi Main 24 fi boilers and other models
VIDEO The reasons are the failure of one or more sensors. Their replacement is required, after which the boiler operation becomes stable.
Relevant for double-circuit boilers Baxi Main for, Baksi Eco for, Baksi Luna 3 Comfort and other models. The temperature in the hot water supply circuit drops sharply or gradually. The cause of the malfunction is a breakdown or incorrect operation of the three-way valve.
To be sure of its malfunction, you need to turn off the double-circuit boiler, wait for the coolant in the system to cool, then close the valves that lock the heating circuit, turn on the boiler in the DHW heating mode and check the temperature of the coolant and hot water. If the valve breaks, it will be warm in both circuits.
Specific pops in the boiler combustion chamber can appear for several reasons:
gas pressure drops (error e01 occurs);
the gap from the igniter to the gas pipeline does not meet the operating requirements, it must be 4-5 mm;
the flue gas draft is too intense.
If any of these faults are detected, adjustments are made:
change the minimum gas pressure limit by 5 mbar;
set the correct gap;
regulate traction with a damper.
The appearance of the e10 code on the electronic control unit of the Baxi Main 24 fi boiler or another model indicates several possible malfunctions:
a decrease in the pressure of the coolant due to blockages, leaks, pump breakdown;
malfunctions of the minimum pressure switch itself;
loss of contact between the control board and the relay.
To eliminate the e10 error, you need to check the pressure in the system according to the pressure gauge on the safety group, to exclude leaks and blockages. If these measures did not help, and the e10 code does not disappear, you need to check or replace the board or the minimum pressure switch.
It can be caused not only by improper operation of the boiler, but also by the occurrence of blockages in radiators, pipes, when filters are clogged. This most often occurs when the quality of the coolant is low, which causes the deposition of rust, salts, solid inclusions.
To eliminate this malfunction, it is necessary to turn off the boiler, remove blockages and fill in a high-quality coolant in order to avoid a repetition of the breakdown in the future.
With a heavily clogged system, the temperature drops, and the boiler efficiency drops sharply, which leads to a deterioration of the microclimate in the house and excessive consumption of gas. To extend the service life boiler Baxi Main or other model, as well as to maintain high efficiency it is necessary to periodically clean the heat exchanger using a special device and cleaning liquid.

Repair and maintenance of boilers with the appearance of error codes e01, e03, e10 can be done by hand. More complex malfunctions , entailing complex adjustment or replacement of elements, require a specialist call for gas equipment. In addition, it is better to contact the service center if the boiler is under warranty, since self-repair will lead to its cancellation.

Eh! Thanks! Neighing!
Dok1986 , About the filter. This is the first cause of all boiler malfunctions - according to customers. All my repairs, including faulty boards, begin with the client's words - “probably the filter needs to be cleaned”.
Glad that I amused you. But seriously, I washed the heat exchanger with chemistry. All the scale is gone. the flow through it is good. The radiators and the soap system are simply water from the mains. The water flow is good. Judging by the logic of the boiler operation, the CO sensor (it is free of scale), without heating to the required temperature, for example 75 degrees, would give the command to modulate a large flame. This is not the case in this situation. See above.
Comrade Poleznii, please state your version in more detail. Quite interesting.
Please see the picture of the board and give advice.
I read in the instructions for the BAXI MAIN digit 24 Fi boiler that there is a 30-45 degree mode and it is turned on with a switch on the board. I have the impression that this mode has turned on. Only I don't have a switch. That would be to turn off and not disturb the respected people on the forum.
check the bypass (h.z. what can be with it, but logically fits)
no more thoughts yet
Warnings: 1
scorpionlion stripes color: brown, brown, orange, orange, brown, the colors match the colors in different resistor recognition programs. I know two signs of the beginning of reading: a wide strip and a strip closer to the output. But as luck would have it, the strips are the same and are located the same in relation to the conclusions. Yes, the denomination in my cases and in yours is also not standard. Therefore, doubts.
scorpionlion I have a guess: there is a variable power limiting resistor on the board. Let's suppose that we turned it counterclockwise and judging by the logic, the power should be limited. tomorrow I'll check his work.it’s bad that I don’t know the face value, that there is no scheme, and the worst thing is that I don’t know where to get it. Please correct me if I am lost.
scorpionlion More about resistors, they seem to be in the control circuit from an external device or sensor (I'll check it tomorrow), which is connected instead of a jumper on the block. somewhere on the forums I read that if there is no jumper or the jumper does not connect, then there may be a similar picture. tomorrow I will check and unsubscribe.
For the manufacture of the Baksi combustion chamber, the manufacturer uses metal. Outside, it is covered with a layer of heat insulator. Above it is a heat exchanger made of copper. When the room temperature changes, the thermostat starts. Note that the launch is carried out in automatic mode. From it, the turn-on signal is transmitted to the pump. The latter creates a vacuum in the return pipeline. After that, heated water begins to flow into the heating system line at a pressure not exceeding 0.45 bar.
After that, the mode changes - from heating to modulation mode ... When the temperature of the coolant decreases, a signal is received from the temperature sensor, which leads to the opening of the inlet valve. After this, ignition occurs, and then the water is heated up again.
If already at the beginning of the boiler's operation its power is quite high, then the burner is turned off in automatic mode. After three minutes, the system can be restarted.
If there is no need for heating the room, then the boiler is turned on in the DHW mode. In this case, cold water flows into the secondary circuit through a three-way valve, through which the heating line is shut off. PThe fuel is supplied to the burner by means of a gas valve , which leads to a gradual increase in the boiler output. After the end of water heating, the temperature control mode is activated.
If the Baksi boiler stopped working normally, then you can carry out repairs on your own, without asking for help from specialists. But troubleshooting is possible only if the breakdown is small and easily removable. If you have never encountered the repair of boilers, then in this case you should not risk it - contact the master immediately.
it is impossible to light the boiler;
when the boiler is operating, pops are heard in the combustion chamber;
overheating of the boiler;
becomes insufficient max. heating agent heating temperature;
there is a lot of noise during the operation of the equipment;
one of the system sensors fails.
Reasons for the breakdown of Baksi boilers:
moisture has entered the boiler;
the quality of the heat carrier used is low;
the gas pressure has dropped in the gas pipeline or a drop has occurred;
there was a voltage drop in the power grid;
the installation of the heating system was carried out with errors.
VIDEO
The burner flame does not reach its maximum power during boiler operation
This malfunction of the gas boiler may occur due to an incorrect setting of the pressure in the heating system. Also, such a breakdown may appear with a faulty gas valve modulator. Another reason for its occurrence is the breakdown of the diode bridge.
Remedy: it is necessary to adjust the system parameters using the boiler operating instructions.
The boiler starts up but stops working immediately
This malfunction of the gas boiler can occur due to low pressure in the gas pipeline.
Remedy: it is necessary to adjust the gas pressure down to 5 mbar.
Remedy: Perform a pressure test on the gas valve. Chances are high that min and max have failed.
Modulation mode does not work
To correct the problem, a valve change should be performed.
Temperature sensor values become inaccurate
To eliminate this problem, replace the old sensor with a new one.
Weak heating in the hot water system
The cause of this malfunction may be an incomplete opening of the three-way valve. In some cases, its appearance is associated with a breakdown of such a valve. To establish exactly what the cause of the malfunction lies precisely in the valve , it is necessary to wait a while until the system cools down. Then the shut-off valves of the heating system will need to be closed. When this is done, the boiler should be turned on in hot water supply mode. Valve failure will be confirmed by heating in the heating system.
When the installation is fired up, "pops" are heard
Noise can appear for several reasons:
Insufficient gas pressure;
Changed distance from the gas supply to the igniter due to inaccurate transportation of the Baksi boiler.
To eliminate this problem, you need to adjust the size of the gap. It should be set within 4–5 mm.
How to adjust the gap between the burner and the pilot
The coolant temperature in the circuit has dropped sharply
The main cause of this problem is clogged filters. They must be removed and cleaned. In some cases, they may need to be replaced. Damage to radiators or pipes may also be the cause. If these heating systems are frozen or clogged, then repair is necessary. The area where the defect was found should be cleaned or replaced.
How to clean the primary heat exchanger with your own hands
The pipes of the device should be connected to the heating pipes of the Baksi boiler. ... Then you need to unscrew the lid on the device, and then pour in a special liquid intended for cleaning. Then the device is connected to the mains.
For several hours on the device, we switch the direction of the flushing liquid in manual mode. When two hours have passed, the device must be turned off. Next, unscrew the tap to drain the water. Then you need to remove the hoses. But before that you need to make sure that the liquid is glass back into the device ... Next, we connect the boiler to the system. After that, it must be filled with a coolant. After cleaning the boiler, its parts must be descaled. And this will exclude clogging of the system and its failure.
DIY cleaning of the secondary heat exchanger (heating circuit)
Before installing the boiler, you need to consult a specialist. You should also contact him in the case when the boiler needs repairs. Baksi gas equipment, like any other, has its own ultimate strength, therefore, at a certain point, boiler repair will be required.
Error codes that may occur during the operation of Baksi gas boilers can be divided into two groups:
complete blocking of equipment operation;
switching the device to standby mode.
In case of complete blocking of the installation, it will be necessary to restart the boiler in manual mode. The blocking is activated in the event of serious malfunctions in the operation of the boiler, which can pose a serious danger to human health. Failures, in the event of which the boiler is blocked, can be attributed to overheating of the equipment, and besides it, the lack of traction. Blocking occurs even in the absence of gas supply. Self-elimination of the error is carried out in rare cases. If this happens, the device starts up in automatic mode.
This mistake is the most common one. When the flame sensor is triggered, this code is displayed. Several reasons can lead to its appearance:
there is no correspondence between phase and zero; this reason is relevant for phase-dependent models;
no contact with the flame sensor;
the sensor is dirty or defective;
the ignition system malfunctions;
the gas valve is faulty or the electronic board is out of order;
air access is insufficient for normal combustion;
the gas pressure in the system is insufficient.
If this code is displayed on the display, then the first thing to do is to check if the sensor is connected correctly. It is also worth checking the gas supply. If everything is normal, then in this case you can press R. It should be held for 3 seconds.
If accidentally triggered, the equipment will continue to operate normally. If the error continues to appear, then in this case you should contact a specialist ... Note that this error is due to an electronics problem. If you try to solve the problem on your own, then everything can end in disaster for the gas equipment.
Another common mistake is E10. The main reason for its occurrence is sensors that monitor the operation of pumps and monitor the circulation of water. This error can be displayed on the installation display in the following cases:
contact between the board and the pressure switch has disappeared;
the pressure switch is defective;
the pump operation sensor has become faulty;
there are malfunctions in the pump;
clogging of the heat exchanger.
When this error occurs, you do not need to try to fix it on your own. Self-repair is acceptable if pump replacement is required. It will not be difficult to hold this event. You can also clean the filters without assistance. All other work related to the repair of the Baksi boiler should be performed by an experienced specialist.
Urgent repair by a qualified specialist is required if errors E96, E97, E98 are displayed on the gas boiler display. If they occur, it is unacceptable for the owner of the equipment to interfere with the operation of the boiler. The prohibition on intervention with these errors is due to the fact that these three codes appear in the event that the electronic board has become faulty.
The resulting error codes help the owner of gas equipment to track any, even the smallest, malfunction in its operation. Repairing the Baksi boiler should be considered as something akin to curing a disease. It is much easier to get rid of it only with timely diagnostics.
Baxi is a line of gas boilers from an Italian manufacturer.The best option for keeping the room at a comfortable temperature. Gas boilers of this company are safe, environmentally friendly, durable, practically silent, durable and economical, have high performance and are quite easy to operate, in addition, they have an affordable price. Even if a decrease in gas pressure is noted in the network, the boiler will not stop working. Baksi boilers run on liquefied natural gas. The modern design allows you to organically arrange the boiler in the interior of any room.
In order to choose the correct spare parts for the boiler after an identified breakdown, you need to know its series and model. The most common: Baxi Luna (Comfort, Comfort Combi, Silver Space), ECO, Nuvola (come with a stainless steel boiler), Slim, Main.
VIDEO
The volume of boilers ranges from super compact to 80 liters. They can be floor-mounted or wall-mounted. Structurally, boilers are divided into: single-circuit and double-circuit.
The combustion chamber of baxi boilers is made of metal. The outside is covered with a layer of thermal insulation. A copper heat exchanger is located above the combustion chamber, and the burner is located under the combustion chamber.
When the room temperature changes, the thermostat is automatically started, transmitting a signal to turn on the pump, which creates a vacuum in the return pipe. In this case, heated water begins to flow into the supply line of the heating system at a pressure of no more than 0.45 bar (in case of pressure increase, the microprocessor sends a signal to the relay, the contacts close, and the burner ignites). Boiler operation starts at low power, which gradually increases until the temperature of the heating medium reaches the set temperature. After that, the heating mode is changed to modulation mode. As soon as the temperature of the coolant deviates from the set value towards a decrease, a signal is received from the temperature sensor, the inlet fuel valve opens, the burner ignites again and heats up the water.
In the event that at the beginning of operation the boiler output is too high, the burner automatically switches off and the system can be restarted only after three minutes.
When there is no need for heating, the boiler is switched on to DHW mode. In this case, cold water through a three-way valve that closes the heating line enters the secondary circuit. From the gas valve, fuel flows into the burner, gradually increasing the power. When the water heats up, the temperature control mode is activated.
Repair work in baxi boilers should be done with your own hands only if there are visible and easily removable reasons for the breakdown. In the absence of experience in handling the units or in the absence of special tools, it is better to entrust the boiler repair to a competent foreman.
- the boiler burner does not turn on or goes out;
- ignition becomes impossible;
- pops are heard in the combustion chamber;
- the boiler is overheating;
- the maximum heating temperature of the coolant becomes insufficient;
- boiler operation becomes noisy;
- one of the sensors or system elements fails.
Reasons for the breakdown of baxi boilers:
- moisture has entered the boiler;
- water (heat carrier) of poor quality;
- there was a drop or drop in gas pressure in the gas pipeline;
- there was a voltage drop in the mains;
- the heating system has been installed incorrectly.
VIDEO
It is possible that during installation, the phase and zero are connected incorrectly or air has accumulated in the system.
The cause of the malfunction may be an incorrect setting of the pressure in the heating system, a malfunction of the gas valve modulator or a breakdown of the diode bridge.
Remedy: adjust the system parameters using the boiler operating instructions.
The reason is the low gas pressure in the gas pipeline.
Remedy: reduce the value of the incoming gas pressure to five mbar (standard - twenty-five mbar).
Remedy: check the pressure value on the gas valve, most likely the min and max values have failed.
It is obligatory to change the board, as well as the valve.
Replacing the sensor with a new one will help fix the problem.
The reason for this is the incomplete opening of the three-way valve or its breakage.To confirm a valve malfunction, let the system cool down, close the shut-off valves of the heating system, then turn on the boiler in hot water supply mode. If the valve is faulty, then simultaneously with DHW heating will occur in the heating system.
Such noise appears due to: insufficient combustion of the gas (it is necessary to adjust the minimum pressure); changes in the distance from the gas supply to the igniter during inaccurate transportation of the baxi boiler (you should adjust the size of the gap by setting it to 4-5 mm); excessive draft (using the damper to reduce the draft in the boiler).
Open the front panel and remove it completely from the boiler. Remove the flap from the inspection hole. Behind it is the igniter. To change the size of the gap, it is necessary to unscrew the screw on which the ignition electrode is attached, then remove and carefully bend the electrode. Then we put it in place and close the hole flap.
The reasons for this are: clogging of filters (cleaning or replacement is required); damage to pipes, radiators, their clogging or freezing (the malfunction must be identified and replaced or cleaned the defective section of the pipeline).
VIDEO
We drain the water by unscrewing the tap on the boiler on the right. If possible, drain the water from the heating system. For cleaning we use a device called Jelly. We connect the pipes of the device to the heating pipes of the baxi. We unscrew the lid on the device, fill in the cleaning liquid. We include Jelly in the power grid. Within a couple of hours, use the knob on the device to switch the direction of the flushing liquid "forward - backward". After two hours, turn off the device, turn off the tap to drain the water from the boiler. We remove the hoses, making sure that the flushing fluid is glass back into the device. We connect the boiler to the system, fill it with a coolant. Cleaning the boiler will remove scale from its parts and prevent clogging and breakdowns.
We use the flushing device again. We connect it to the boiler, turn it on. Close the gas tap and open the hot water tap. And after that we turn off the device for cleaning. Thus, the liquid will be driven along the short circuit of the system.
Before installing the boiler, its operation and repair, be sure to consult with a specialist. Despite all the positive qualities of baxi boilers, they, like all equipment, have their own margin of safety and service life. In this article, we examined the main types of breakdowns, and also saw how to repair baxi boilers with our own hands. We wish you and your boilers success.
Analysis of errors and malfunctions of gas boilers Baxi
Almost any buyer of wall-mounted gas boilers Baxi, sooner or later, is faced with some kind of malfunction and breakdown of the device. Experts strongly recommend carrying out preventive maintenance of the gas boiler at least once a year: rinse the heat exchangers, clean from the formed scale, check the sensors' performance before the start of the heating season.
However, modern heating equipment tends to break down over time, which will require its repair or replacement of spare parts. Consider one of the most popular brands in Russia - the Baksi gas boiler, its malfunctions and errors that are shown on the control panel under special codes under the symbol "E", which is an abbreviation of the English word "Error" - an error.
Consider the main malfunctions that the user of the Baxi gas boiler may encounter when there is no hot water and why the boiler does not heat water, the pressure drops, the burner of the Baxi Main Four 240F or Baxi Eco Four 24F boiler and other models does not turn on or ignite.
We will analyze all the errors of the device according to the instructions, the reasons for their occurrence and the methods of eliminating the malfunctions that have arisen on our own or by specialists.
Baksi gas boiler display
Italian wall-mounted double-circuit and single-circuit gas boilers are equipped with an informative digital display, which displays not only information (symbol "A"): water temperature in the heating system or in the DHW circuit, or parameter settings (symbol "F"): operating modes and warnings, but also errors under the "E" codes.
If the display shows the symbol "R", it means that a malfunction has occurred and you can try to fix this malfunction yourself. To do this, press the "R" button and hold it for a few seconds. If this does not help, then it is better to immediately call a specialist gasman to the house.
Nevertheless, let's take a closer look at the error codes that we may encounter when operating the Baxi boiler.
This is one of the most common mistakes that occur during the operation of Baksi gas boilers. It signals that there is no ignition in the device, as a result of which the boiler does not turn on.
2. Possibly defective flame electrode or wire leading to the ignition unit.
3. Defective gas valve or electronic board. Check all connections between them.
Another frequent error under the symbol "E02" indicates to us that the safety thermostat of the Baxi boiler has tripped. Usually this error is displayed when the boiler does not heat water well in the heating system.
1. Check if the pump impeller is blocked if there is no circulation of the heating medium.
2. The main heat exchanger may be clogged and needs to be cleaned.
3. It is also necessary to check the connection of the limit thermostat and the temperature sensor NTS of the heating system at the inlet to the boiler.
4. Defective electronic board can also cause error E02.
This error indicates that when setting up the boiler, parameter F43 was set incorrectly, which leads to an error in the configuration of the electronic board. To change the settings, press and hold two buttons simultaneously for at least 6 seconds:
This malfunction can occur in two cases:
- there is no ignition;
1. It is necessary to check the integrity of the connections between the ignition unit and the flame sensor, as well as between the board and the gas valve.
2. Insufficient draft may cause flame blowout.
The temperature sensor of the heating circuit at the entrance to the Baxi gas boiler is out of order. It is also possible that the wiring of this sensor is broken or short-circuited.
The DHW (water) temperature sensor is faulty or its wiring is broken, the circuit is open, the wiring is short-circuited.
Errors E07 and E36 .
It may be necessary to replace the temperature sensor of the combustion products (exhaust gases) or its wiring has been broken.
This code signals that an error has occurred in the flame signal amplification circuit due to the lack of grounding of the electronic board. It is necessary to check the “x4” connector between the power terminal and the board itself.
A malfunction of the electronic board of the Baksi boiler gives an error in the gas valve protection circuit. The board will need to be replaced.
This error indicates a malfunction in the hydraulic pressure switch or a break in its wiring. Also measure the pressure in the boiler heating circuit. Error E10 can appear if the pressure drops below 0.5 bar.
The exclamation mark is flashing .
Error warning on display
Another reason for this malfunction may be an incorrectly assembled chimney, especially with regard to its length. All these nuances can indicate to us in this case that the Baxi gas boiler is operating at its minimum capacity.
There was a voltage drop in the power grid below 160 volts. The boiler automatically restarts or shuts down spontaneously. It is necessary to identify the cause of the low voltage in the network.
A fairly common error of the Baksi boiler can occur in the absence of normal water circulation in the heating system.
one.Due to a clogged heat exchanger or a jammed pump, circulation in the heating circuit has disappeared.
2. A malfunction of the NTS heating temperature sensor at the inlet or its overheating (error E26) can also be the reason for the lack of circulation.
It is necessary to check the reliability of the fixing of the DHW temperature sensor and its contacts; the sensor clip may have disconnected from the pipe on which it is installed.
Meanings of symbols on the display of the Baxi boiler
This error can signal a false (parasitic) flame signal.
1. The electronic board is not grounded.
Errors E40 and E41 .
These errors occur when the gas inlet pressure is insufficient, which must be at least 9 mbar, or the boiler flue pipe is clogged. These problems can be caused by:
- incorrectly adjusted pressure on the gas burner;
"Battery" and "Crane" symbols flash alternately .
Scale has formed in the heat exchanger due to "hard" water. This usually becomes noticeable when the boiler does not heat water well in the DHW circuit, and the batteries heat up well. It is necessary to clean the main heat exchanger with a special descaling liquid. The DHW temperature sensor may need to be replaced.
This malfunction is typical, as a rule, for Baxi turbocharged boilers with a closed combustion chamber. Because the error "E42" is associated with the operation of the fan (turbine). It is also possible that the voltage in the network has dropped below 180 V, or the chimney is clogged, which must be cleaned.
If the flue gas temperature exceeds 180 ° C, an emergency sensor is triggered, which is indicated on the display by the error "E50". Another reason may be clogging of the main heat exchanger with scale, due to which the circulation in the boiler is not sufficient.
This code "pops up" when the parameters of the gas valve are incorrectly set. This happens, for example, after replacing the electronic board of the boiler.
With faulty flue gas and flame sensors, the boiler gives an error about the unstable signal received from them. Check the wiring of these sensors or replace them. There may also be a problem with the electronic board.
Frequent activation of the function of checking the clogging of the boiler chimney. This is either due to too low gas pressure or flame and exhaust gas sensors that have come out of the standing position. It is also recommended to check the boiler flue for clogging and check the burner setting.
When replacing the electronic board of the boiler with a new one, the parameters F03 and F12 on the board were not set. It is necessary to adjust them in accordance with the Baksi boiler model.

The symbol "St" flashes and the temperature of the heating medium is below 2 C .
The heating circuit is frozen or the heating input temperature sensor is faulty. The burner does not start because the boiler defrosting function is on. It is recommended to turn off the power supply to the device, then completely defrost the boiler and turn it on again.
The "LoP" symbol is flashing .
Insufficient inlet gas pressure, which, according to the regulations, must exceed 6 mbar. The boiler has a low gas pressure function. The gas valve settings need to be adjusted.
We have analyzed the main malfunctions of the Baksi gas boiler, errors that occur when the device breaks down, which are highlighted on the boiler display. We considered the causes of these malfunctions and methods of their elimination.
