The main reasons for the failure of Baxi heating equipment:
Twenty years ago, a boiler was considered a simple device, the main purpose of which is to generate heat. Today the requirements for heating equipment have changed dramatically. Now the boiler unit must be able to maintain a comfortable temperature in automatic mode, prepare hot water in the required amount, be energy efficient, environmentally friendly and safe. Baksi gas boilers not only meet all modern conditions, but, in some respects, surpass them. So, for example, boilers of the series Baxi Luna – 3
, NUVOLA
, ECO
have a built-in self-diagnosis system and many integrated safety devices and sensors to ensure the most reliable and safe operation. And yet, during the operation of the boiler, it becomes less efficient, and its reliability decreases.
This is due to the influence of 4 main factors:
- natural gradual wear of parts;
- surface contamination with salt deposits and carbon deposits;
- the peculiarities of the operation of heating equipment in our country - the heating season in our country lasts longer, therefore the load on the equipment is higher;
- low quality engineering systems.
Noticing and eliminating all problems as early as possible means saving yourself from damage to boiler equipment and costly repairs to the baxi boiler. During regular service inspections, our engineers not only carry out all the measures prescribed by the manufacturer, but are also ready to eliminate all the shortcomings and mistakes made during the installation of equipment by third parties and carry out a complete modernization of the heating system.
Certified service is the key to efficient equipment operation for many years:
The long-term experience of the specialists of the authorized service center E-Tech has shown that it is the discrepancy between the operating conditions and the established standards, as well as the requirements of equipment manufacturers, that is the most common reason for the failure of even the most advanced equipment. For example, according to statistics, one of the most common causes of boiler breakdowns Baxi main
poorly treated water and low-quality fuel; Baxi AMPTEC
- voltage surges, disabling the automation. Baksi specialists tried to neutralize some of the negative factors in advance by equipping all models of boiler units with a reliable safety control system and adapting them to work in Russian conditions. However, the identification of most defects in the boiler piping and their neutralization falls on the shoulders of the service specialists.
Our engineers are ready to undertake the entire range of services for the heating system based on the Baxi boiler. Before starting work on direct maintenance (cleaning of working surfaces, replacement of spare parts for baxi boilers, etc.), the specialists of the E-Tech center will conduct a comprehensive diagnosis and determine the whole range of factors that negatively affect the operation of heating equipment. In the course of the service, the automation will be calibrated to establish the most efficient operating mode. After carrying out maintenance, our specialists will draw up a Certificate of Completion, in which they will indicate the malfunctions that require separate repairs, as well as recommendations for the operation of the boiler. Modern technical support and our own warehouses of spare parts allow us to perform work of any complexity and level of responsibility in a short time and with maximum efficiency.
Today, a gas autonomous heating system is quite popular; it is used not only by the owners of country houses, but also by apartments located in multi-storey buildings.This can be explained by the positive qualities of modern devices, ease of installation and operation, which is confirmed by many reviews of experienced specialists and consumers.
Practical advice
To exclude the appearance of "random" errors (and they are regularly displayed as a result of power instability), you can connect the gas Baxi to the network via a UPS. On sale are various modifications of blocks designed to work together with household boilers.
The stabilizer and UPS are connected to the Baxi boiler
Unlike the stabilizer, this device will give out voltage to the heating unit even if the power line is broken and the backup generator malfunctions. The autonomy of the UPS is provided by built-in (or attachable external) batteries. Users note that after installing it on site, the number of Baxi boiler errors that appear is dramatically reduced.
Step 6
A clogged heat exchanger of the Baksi boiler is a likely cause of the e25 error. The liquid passing through it leaves scale on the inner walls when heated. The channel cross-section, the circulation speed is reduced, the NTC sensors record an accelerated increase in the temperature difference, the automatic equipment issues the 25th fault code. The heat exchanger requires regular maintenance. If the liquid entering the heating system from the water supply system is of increased hardness, then it is advisable to do this more often than the manufacturer recommends in the instructions for the Baksi boiler.
p, blockquote 14,0,0,0,0 ->
There are appropriate preparations on sale that effectively clean the cavity of the heat exchanger. Service workshops provide a similar service: the cost depends on the region, but not more than 1,500 rubles with a work completion period of 2-3 days. You can carry out the service yourself, and it is completely free of charge.
DIY Baxi boiler repair - Video lesson
Burner flame does not reach maximum power
The fault may be due to an incorrect pressure setting 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 boiler starts up and stops working immediately.
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).
Weak heating in the hot water system
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.
"Pops" are heard in the boiler during firing up
Such noise appears due to: insufficient combustion of the gas (adjustment of the minimum pressure is required); changing the distance from the gas supply to the igniter during careless 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).
How to adjust the gap between the burner and the pilot
Open the front panel and completely remove it 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.
A sharp decrease in the temperature of the coolant in the circuit
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).
How to clean the primary heat exchanger with your own hands (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.
Cleaning the secondary heat exchanger (heating circuit)
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.
System errors
When malfunctions occur in the double-circuit wall-mounted gas boiler "Baksi", an error code is displayed on its electronic display, which can mean one of two things: either blocking the operation of the heating device, or turning on the standby mode.
In the first case, it is necessary to manually restart the boiler. The device can be blocked at the moment of detection of problems affecting the basic parts of the system, which can harm not only the equipment, but also the health of its owner. Such errors include excessive heating of the boiler, insufficient or reverse draft, as well as its absence. If no gas is supplied to the storage tank, the equipment is also blocked. Sometimes this problem resolves itself, and then the device turns on the automatic startup mode.
Code E01 - burner sensor
Code E01 appears on the display when the sensor, which monitors the operation of the burner, reacts. This error can be caused by a number of reasons:
- gas is no longer supplied to the burner;
- there is no correspondence between zero and phase;
- the sensor is disabled;
- the sensor needs cleaning or repair;
- malfunction in the igniting device;
- the gas supply valve is out of order;
- the electronic board does not work;
- there is not enough air to support the flame;
- there is not enough gas pressure for combustion.
If the sensor is triggered unintentionally, the boiler will continue to work as usual. In case of a repetition of the error, it is better to ask for advice from a gas equipment repairman. This fault code indicates a problem in the microcircuits, and trying to fix the problem yourself may lead to undesirable results.
E10 - water cycle indicator
Code E10 refers to sensors that monitor the functioning of pumps and regulate the water cycle in the system. Such a cipher can diagnose the presence of the following problems:
- decreased pressure;
- the conductivity between the relay and the board is broken;
- the pressure switch is not functioning properly;
- malfunctions in the pump sensor;
- the pump itself needs to be repaired;
- the heat exchanger is dirty.
E96−98 - problems of the electronic board
The rest of the codes E96, E97, E98 indicate problems in the operation of the electronic board. If they appear on the display, the owner should not take any action and immediately call the repairman, because only an experienced specialist can handle them without outside help.
Fixing problems with household appliances is a kind of treatment. There are simple diseases that a person can expel on their own, and with complex diagnoses, it is better to consult a doctor.But both can be prevented with the help of timely prevention. This also works in case of warning of malfunctions of the wall-mounted double-circuit gas boiler "Baksi".
Regular service and maintenance of Baxi boilers in E – tech:
Modern heating units are distinguished by high reliability, which is due to the use of the latest technical solutions and materials, as well as the increasingly widespread use of regulatory and protective automation. However, it is wrong to rely only on the quality of equipment manufacturing. Any manufacturer will say that only regular service will help your boiler maintain excellent performance and operational safety for many years. In addition, it is the service contract with a certified organization that is the main requirement for maintaining the warranty for the equipment installed at your facility.
Persistent reminders about the need for regular maintenance of boiler equipment are not at all accidental - every boiler is a potential source of danger. You should not wait until the Baxi boiler gives a signal about the need for service itself, because with a favorable development of events, this will be a simple triggering of the warning automatics (for example, Baksi Main
has electronic protection against scale formation, which gives a signal when it is necessary to clean the heat exchanger), in the worst case, the heating unit will fail.
Positive features
Malfunctions of the Baksi boiler, of course, sometimes occur, but it still has more positive features - automated operation, environmental friendliness, acceptable cost, ease of operation, and maximum adaptation to difficult conditions. The latter feature is relevant for Russia.
Due to the fact that the equipment is automated, it can function for a long time according to a certain program. This is convenient for country cottages, in which the owners do not live permanently, but from time to time. During the operation of such boilers, carbon dioxide is emitted into the air, which is absorbed by the plants. This indicates the environmental friendliness of such devices. The manufacturer made sure that the buyer repairs Baxi boilers as little as possible. The main faults and remedies are described below.
The equipment in the manufacturing process is supplied with protective chips that are able to neutralize voltage fluctuations in the network.
What is a gas boiler error?
During the operation of the equipment, a situation may arise when the protective automatics are triggered. That is, the gas boiler detects that something is not working correctly and is blocked. To facilitate the search for the cause of the malfunction, most gas boilers are equipped with a malfunction display system for initial diagnostics. Somewhere it can be a combination of LED signals, in some cases an error code indication on the display, in some cases the display shows a specific cause of the malfunction (some premium boilers). The fault itself can be critical (emergency), or insignificant - requiring simple user action. Also, in some cases, the operation of the boiler is blocked until the error is reset (for example, there is no water pressure in the boiler), and in other cases, the error must be reset by the user (for example, problems with the ignition of the burner).
Most often, the procedure for dealing with errors is described in the user manual that comes with the gas boiler. It also indicates how the error is reset.
MORA boiler and EFD-503 control units
A case from practice. Several EFD-503 units came for repair. Such blocks are installed directly on the gas fittings, used in boilers MORA, BERETTA, PROTHERM and others.So, specifically in this modification of the block, the error is reset through the closure of two contacts on the block itself, and the switching is displayed on the control panel with a button. The client says I change blocks consistently once a year. I'm tired of changing (the price of 1 unit is about 10 thousand, and there are two of them in the boiler) turned to us for repairs. On the provided blocks, faults were indeed identified and eliminated - the blocks were sent back. Installation result 1 block works, two worked for 20 seconds, went into an error and no longer work.
The likelihood that the control unit only worked for 20 seconds after repair is very small (two units at once - all the more so). A “phasing error” is more suitable for the description of a malfunction - a non-observance of the polarity of the connection. I ask - what actions does the boiler perform before the error appears? The answer is none, just a mistake and that's it. I explain that the error should be reset, maybe your contact is bad on Reset. No, about the theory of contact - we know that the blocks are faulty. Okay, send it in. The client sends two blocks after repair and two more additionally from the “faulty” collection. First, we install the blocks that were repaired on the stand. Blocks in error. We reset the error - the ignition is on, the valve opens, the block sees the flame - it is working properly! We deliberately create an error on the block, reset it again - there is ignition, the board works according to the logic. We check all four blocks in the same way - everything is in error, after the reset everything works. We provide information to the client about which contacts are closed on the block to reset the error, he takes the "faulty" block from the collection and voila! - works. All questions have been cleared.
And this case is not the only one. This often happens, and on different boilers.
Baksi is the name given to a line of gas boilers from an Italian company. If you are faced with the task of providing a comfortable microclimate in the room, then Baksi boilers are the best solution. The installations of this manufacturer have many advantages. Most importantly, Baxi boilers are economical. In addition, they can be operated for a long time and not emit noise during operation. These units show good performance during use and are easy to use. The reasonable price for this equipment makes it affordable for most consumers.
Step 4
The circulation of the liquid is impeded by air in the heating circuit. Restarting the unit allows you to deal with small bubbles, but if we are talking about a "plug" tightly blocking the line, the R button on the Baksi boiler control panel will not help to eliminate the e25 error.

It is easy to find the problem place by walking around the object, by touching the degree of heating of pipes and heating batteries. It will be indicated by a lower temperature. You shouldn't rely on automatic valves (if radiators are equipped with them) - they often fail.
p, blockquote 10,0,0,0,0 ->
For 100% certainty, you need to bleed air from the line, where it is provided, manually. Including, check the pump air vent - it must be in working position. For this, the adjusting knob is screwed in and then unscrewed by 1–1.5 turns, or the flag is raised (depending on the model of the pumping device).
p, blockquote 11,1,0,0,0 ->
The floors are examined in parallel. Leakage is the cause of error e25. The burner of the Baksi boiler works in accordance with the set mode, but if the volume of liquid in the circuit gradually decreases, it heats up faster than 1 degree / sec, which is fixed by the NTC.

Eliminating failures
If the flame is not powerful due to incorrect operation of the gas valve, a system pressure adjustment is required. This must be done in accordance with the requirements of the instructions.The diode bridge often fails. Then not a repair is required, but a complete replacement.
Baksi fee
If the coolant does not heat up well, check the pressure at the outlet of the gas valve. Change the position of the regulator and try to restart the boiler. That's the whole repair.
If there are deviations in the readings of the sensors, they need to be changed.
When the temperature is unsatisfactory in the DHW, check the functionality of the three-way valve. They wait until the water has completely cooled down, then close the heating taps, and then turn the heater back on to the hot water supply mode. If heating goes on in the heating, the valve is faulty. It needs to be replaced.
When strong pops are heard at the time of ignition, the reasons for what is happening are as follows:
- Gas supply pressure too low.
- Increased distance from nozzle to igniter (due to improper transportation).
In such cases, it is necessary to adjust the clearance. It should be within 4-5 mm. Open the front panel, unscrew the electrode fastening screw, remove the electrode, bend it a little and put it in place.
Maintenance and cleaning
With a heavily clogged system, the temperature drops, and the efficiency of the boiler drops sharply, which leads to a deterioration in the microclimate in the house and excessive consumption of gas. To extend the life of a Baxi Main boiler or another model, as well as to maintain high efficiency, it is necessary to periodically clean the heat exchanger using a special device and a cleaning liquid.
Video: flushing the Baxi Main boiler
Repair and maintenance of boilers when error codes e01, e03, e10 appear, you can do it yourself. More complex malfunctions involving complex adjustment or replacement of elements require a call to a gas equipment specialist. In addition, it is better to contact the service center if the boiler is under warranty, since self-repair will lead to its cancellation.
Errors and their codes
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.
Error E01
This mistake is the most common one. When the flame sensor is triggered, this code is displayed. Several reasons can lead to its appearance:
- no gas supply;
- 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.
Error E10
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:
- the pressure of the coolant has decreased in the system;
- 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.
Errors E96, E97, E98
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 to interfere with the operation of the boiler by the owner of the equipment. 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.
Design and principle of operation
The best option for apartments is a wall-mounted double-circuit boiler. Such models are produced in several series, differing in power, smoke exhaust system and type of gas burner. For apartments, it is recommended to choose a device with a forced draft. The calculation of the power is simple - the square of the living space is divided by 10. This gives the required boiler power in kW.
Small boilers of the Main series with a bithermal heat exchanger, to the tubes of which copper plates are spot welded. This increases the efficiency. The design includes an expansion tank and a circulation pump. Filtration of incoming water is provided. The heat exchanger is installed on top of the firebox.
Combustion chambers of Baksi boilers are made of metal and are covered with a heat insulator from the outside.
The system works in the same way as all gas boilers. The signal from the thermostat goes to the pump, which creates a vacuum in the return. Water under low pressure (less than 0.45 bar) enters the heating system. The ignition takes place automatically.
The output power rises smoothly with increasing temperature. When it reaches the set value, the operating mode will switch from heating to modulation. When the temperature drops, the thermostat will command the inlet valve to open and the water will be heated again.
If the burner shuts down due to over-power immediately after starting, then restarting is allowed after three minutes.
Baksi device
Hot water supply is as follows. Water is supplied through a three-way valve that blocks the heating line and enters the secondary circuit. There it heats up and goes to taps for personal use.
But no matter how trouble-free the Baksi is, it also breaks down sometimes.
Basic units and principle of operation
The Baksi line of gas boilers includes a number of models that differ in volume, type of installation, 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
According to the type of installation, gas boilers are divided into wall-mounted and floor-standing.
The wall heater is fixed with 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.
The volume of the coolant in the heat exchanger depends on the model, in the most powerful it reaches 80 liters. In terms of functionality, the models can be single-circuit - for heating, or double-circuit - in addition to the heating system, they also feed the DHW circuit.
They can work both on natural main gas and on liquefied gas, from cylinders, which makes it possible to install them in non-gasified areas. The boilers are 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 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 the heating process (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. Improper repairs can lead to complete failure of the boiler!
Step 2
Check voltage. Failures of network parameters are typical for the private sector, in areas of intensive development. Phase imbalances, decrease in value less than recommended by the manufacturer (
230 V) is not uncommon, hence the error e25. Disruptions in the operation of an autonomous power source are possible: imported household appliances are sensitive to the parameters of the electrical network, which users forget about.
p, blockquote 6,0,0,0,0 ->
Simultaneous operation of a powerful consumer of electricity / energy or several devices (pump, boiler, dishwasher or washing machine, electric heater) with the Baksi boiler leads to a decrease (drop) in voltage. If the cause of the e25 error is this, it is removed by turning off the parallel operating household appliances. In this case, you need to deal with the in-house power supply circuit and build it correctly.
