Baksi boilers: basic faults, error codes, DIY repair

Double-circuit wall-mounted boilers "Baksi" - gas equipment for individual heating from an Italian company. They are compact, comfortable and reliable. However, malfunctions also occur in the operation of the Baksi boiler, and it is worth knowing about their elimination in advance.

The boilers of this manufacturer have many advantages. The main advantage is cost effectiveness. Their service life is long enough, and during operation they practically do not make noise. Using this heating device, you can also note the high performance and ease of use. In addition, Baksi boilers are sold at affordable prices, and representatives of all segments of the population can afford them.

Work algorithm

manufactures metal combustion chambers for its boilers. From the outside, the part is protected by a heat-insulating layer. There is a copper heat exchanger just above the chamber. When the heated room gets warmer or colder, the thermostat turns on. Its work is automated. The thermostat sends a signal to turn on the water pump. He begins to pump water due to the creation of a vacuum in the pipes. Then warm water enters the pipeline.

Boiler power increases gradually when switched on. This happens before the water temperature rises to the required value. Then the heating mode goes into modulation mode. When the coolant cools, the temperature sensor gives a signal to open the inlet valve. This starts the electric ignition, and the water temperature reaches the desired level again.

If the room does not need to be additionally heated, the boiler starts operating in the DHW mode. It consists in the fact that cold water enters the secondary circuit through a three-way valve, which, in turn, blocks the heating line. Gas is supplied to the burner using a special valve, and the power of the appliance gradually increases. When the water is already heated to the desired temperature, its regulation mode is activated.

Error 10

You can easily repair gas boilers with your own hands. Tips and rules of work are collected in the article. If error 10 appears on the display, the fan may have been malfunctioning, kink may have occurred, or the tubes may have been incorrectly connected. Experienced users emphasize that a clogged chimney leads to this error. If there are strong gusts of wind outside, the malfunctions mentioned above may occur. In this case, sometimes it becomes necessary to replace or repair the fan. You can check and clean the chimney on your own. More experienced craftsmen will analyze how correctly the pipes that go from the air sensor to the fan are connected. If there are kinks, then get rid of them.

Malfunctions and their causes

Boilers are good because in the event of a malfunction, it is possible to cope with the repair yourself, without resorting to calling specially trained people. True, it is acceptable to do this only if the malfunction is typical and can be eliminated according to the scheme. For those who have not had the chance to repair gas equipment, it is better not to repair Baksi boilers with their own hands, but to call a specialist. Among the typical malfunctions of the units, the following are found:

the burner does not ignite or constantly goes out;
ignition does not work;
there is a knock in the combustion chamber when the boiler is operating;
exceeding the permissible temperature inside the device;
the maximum water temperature becomes lower;
the occurrence of loud noise during operation;
breakage of temperature or pressure sensors.

The reasons for the failure of the Baksi boiler may be as follows:

water ingress into the boiler;
insufficient quality of the applied coolant;
weakening or sudden change in gas pressure;
power surge in the network;
initial inaccuracies in the installation of equipment.

The reason for the error

Such a malfunction of the Baxi gas boiler can occur if the system is airing, there is a lack of coolant in it. If the circulation equipment is in working order, but is not able to pick up normal speed, this can lead to equipment failure. Damage to the impeller will lead to the same error. Quite often, the flow sensor in the system does not work, the distribution valve is closed.

Troubleshooting Tips

The following points can be used as instructions for troubleshooting the Baksi gas boiler:

The burner is not functioning at full capacity. Such an error in the operation of gas equipment may appear in a situation where the pressure inside the system is incorrectly adjusted. A similar problem also appears if the gas modulator is damaged. Or the diode bridge may be faulty. You can cope with this problem by adjusting the system parameters according to the equipment operating instructions.
The heater turns off immediately after being turned on. This problem occurs in gas appliances due to low pressure in the gas pipeline. Possible remedy: it is necessary to adjust the gas pressure down to 5 mbar.
The coolant does not heat up when turned on. To fix it, it is worth rechecking the gas valve. Perhaps the minimum and maximum values have been reversed.
The modulation mode is defective. This problem can be solved by reinstalling the valve.
Temperature sensors show incorrect data. In this case, you should also dismantle the sensor, replacing it with a new one.
The hot water supplied to the taps does not heat up sufficiently. To restore water heating, make sure that the three-way valve is fully open. This sometimes happens if this device is damaged. To be sure that the malfunction is caused by the valve, you need to wait a little until the system has cooled down. Then close the shut-off valves. Then switch the device to hot water supply mode. If, as a result, the heating system heats up, then it was in the valve, and it needs to be replaced.
Harsh jerks are heard when the burner is ignited. Abnormal noises can occur due to various factors: one of them is too low pressure in the gas pipeline. Another, it happens, happens due to improper transportation of the boiler, when the igniter is displaced, and the distance from it to the gas supply becomes more or less. The solution to this problem is to set the correct distance. It should be approximately equal to 4-5 mm.
You can adjust the gap between the igniter and the burner on the Baksi gas boiler as follows: the front panel is opened and removed from the device. When this is done, the shutter is removed from the inspection hole. There is an igniter. To give it the correct position, you need to unscrew the screw with which the electrode is attached to the boiler. The igniter must be removed, carefully folded and then returned to where it was, and then the damper must be closed.
Strong decrease in the temperature of the coolant. This is often due to dirty filters. The only way to eliminate them is to clean them. Sometimes, in case of severe clogging, the filters must be replaced. It is also worth checking for damage to the pipeline. If, for example, the radiators are clogged or exposed to low temperatures, only repair will help. The damaged segment will need to be replaced or cleaned.

Troubleshooting

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, you will additionally need to check the condition of the boiler components and assemblies. Some breakdowns can be fixed on your own, how to do this is described below.

Boiler start-up is not possible

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 air accumulation in the system. With this malfunction, an error e01 appears on the boiler display, and the coolant pressure drops.

Elimination:

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.

The burner does not work at full capacity

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 in the documentation for the boiler. In the event of a malfunction of the components, it may be necessary to replace them.

The boiler starts up but shuts down immediately

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.

Traction worsens, error code e03 occurs

Error e03 signals serious problems that can lead to boiler failure. You can fix it yourself, the reason may be:

incorrectly mounted smoke exhaust system;
faulty fan;
inadmissible narrowing of the chimney;
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.

After eliminating the causes that worsen traction, the e03 error disappears.

Low temperature of the coolant in the system

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.

The boiler does not work in the mode of maintaining the temperature (modulation)

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

Temperature sensor readings are incorrect

The reasons are the failure of one or more sensors. Their replacement is required, after which the boiler operation becomes stable.

Insufficient water temperature in the DHW circuit

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 make 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.

Pops when starting up and operating the boiler

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 minimum water pressure switch is activated, error e10

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, 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.

A sharp drop in temperature in the heating circuit

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, and 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.

Cleaning the primary and secondary heat exchangers

First, the water must be removed from the heater. There is a tap on the right of the boiler, if you unscrew it, then the liquid will be drained. It would also be good to drain the water from the heating system. A special flushing device is used for cleaning. The branch pipes are connected to the pipes of the gas boiler. Then the cover is unscrewed on the flushing device, and then the cleaning liquid must be poured inside. Then you can connect the device to the network.

Cleaning the heat exchanger is not a quick process and can take several hours. During this time, it is necessary to switch the direction of the flushing fluid. Stop cleaning after two to three hours. After that, the tap opens and the water is drained, and then the hoses are removed. When doing this, you need to be sure that all the liquid is glass in the instrument. After all the manipulations, the boiler is reconnected to the heating system. The pipes are filled with a coolant. Washing the parts of the device should dissolve scale, which will increase the life of the system and optimize its performance.

Similar to the primary one, to clean the secondary heat exchanger, a flushing device must be connected to the boiler. Having connected it to the network, it is necessary to close the gas valve, and move the hot water tap to the open position. Then turn on the device for cleaning so that the reagent moves along a short circuit.

To install Baksi gas equipment, you should definitely use the services of gas service workers. They will also help in case of a malfunction in the boiler. Parts of the heating devices of this company can also wear out over time, so sooner or later, repairs will still be inevitable.

Maintenance and cleaning

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.

Video: flushing the Baxi Main boiler

Repair and maintenance of boilers with the appearance of error codes e01, e03, e10 can be done by hand. More complex faults, 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.

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 main 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 a sensor monitoring the burner is responding. 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.

Having seen such a signal on the display, you first need to check if the flame sensor is working correctly. Then see if gas is supplied to the device. If there are no problems, press the R button or switch the toggle switch to neutral mode, which is also indicated by this letter.

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

E10 code refers to sensors that monitor the functioning of pumps and regulate the water cycle in the system. Such a cipher can diagnose 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.

Having noticed the E10 code, there is no need to rush to cope with the problems yourself. You can also replace the pump with your own hands, it is not very difficult. It is also easy to clean clogged filters with your own hands. It is better to entrust other malfunctions to the hands of a qualified worker.

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 - this 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".

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;
switch 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 acceptableif 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 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.

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. The required boiler power in kW is obtained.

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. If 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 is supplied 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.

Cleaning the heat exchanger circuit

If the heat exchanger becomes clogged, a decrease in temperature and room heating efficiency may occur with a simultaneous increase in fuel consumption. It is difficult to clean the primary and secondary circuits of the heat exchanger on your own, since you need to use the appropriate chemistry and special equipment that provides increased pressure in the system. Cleaning the primary heat exchanger is carried out as follows:

The master drains the water, for which he opens the appropriate taps and nozzles.
Water is also drained from the heating system.
The device for pressurizing the system is connected to the heating pipes of the boiler.
Unscrew the lid on the apparatus and pour liquid from deposits and scale into the heat exchanger.
The fluid used must circulate in the system for at least two to three hours. This time is enough to dissolve and remove even old deposits.
Turn off the device, unscrew the taps and drain the water from the boiler. All flushing liquid must be removed from the equipment, after which it is filled with a coolant.

When self-cleaning the heat exchanger circuit, an active liquid is poured into the boiler through the lid, the device is turned on for heating and it is allowed to work for several hours. After that, a complete replacement of the antifreeze is performed with the obligatory airing of the system.

A similar scheme is used to clean the secondary heating circuit of the Baxi boiler. The gas valve must be closed while simultaneously opening the hot water supply valve. The liquid with the cleaner will be circulated along the secondary short heating circuit, dissolving existing deposits and removing dirt accumulated in the pipes and heat exchanger.

Baxi boilers are popular in the market due to their functionality, versatility, automation and fuel efficiency. But even such equipment can break down during operation and require qualified repair. In the presence of malfunctions in the operation of heating equipment it is best to consult a specialistwho are well aware of the technical features and use special equipment and chemistry to clean the circuit. This allows them to offer quality repair and maintenance services for Baxi equipment.

How to properly solve the problems arising during the operation of Baxi boilers?

Despite the high reliability and durability of the Italian brand equipment, it may one day fail. And although this happens quite rarely, repairing Baxi boilers with the involvement of a specialist will not be cheap. Firstly, the cost of the services of a professional who understands gas combustion technology is usually quite high. Secondly, Baxi components will cost a lot, which must also be taken into account.

But there is a great alternative for those who want to save money - do-it-yourself repair of Baksi boilers. If you are confident in your own skills and do not want to turn to third parties for help, below we will describe all the nuances that you may encounter in the process of repairing the equipment of the Italian brand.

Let's imagine that for some reason your Baxi heating unit is out of order. The first thing you need to do is find out why the unit stopped functioning. In most cases, the built-in automation will give you some error that will point you to the cause of the breakdown. The manufacturer supplies a manual with the boiler, which details all error codes and their interpretation.

After identifying a breakdown, it is very important to select the correct components. To do this, it is necessary to find out the series and model of the boiler. The most popular of them are the Baxi Luna, Slim, Main, Nuvola and ECO units.

Do-it-yourself repair of Baksi boilers should be undertaken, provided that you find easily removable visible causes of a malfunction and you know exactly how to make repairs. Otherwise, if you are not sure that you have sufficient experience in handling such devices, it makes sense to contact a qualified technician.

What kind of breakdowns are most characteristic of the Italian brand's equipment? Let's list the most common ones:

Lack of ignition;
Stopping the burner;
The presence of pops in the firebox;
Overheating of the boiler;
Insufficiently high coolant temperature;
Noisy equipment operation;
Failure of one of the sensors or automation elements.

There are many possible reasons why a Baksi gas boiler breaks down. One of the most common is the ingress of moisture into the boiler. In addition, a low-quality coolant affects the stability of the equipment. Unfortunately, most of Russia suffers from this, which is why from time to time the user will still have to resort to repairs. It should be borne in mind that the Baksi is a rather hardy technique, and an aggressive operating mode has practically no effect on its operation.

Often, the boiler breaks down when there are sudden pressure drops in the gas supply system. At the same time, an automatic safety system is triggered, but its presence does not exclude the occurrence of malfunctions in the operation of equipment. In addition, another problem is urgent for Russia, which can disable equipment. We are talking about the instability of the voltage in the mains.

Very often, the boiler wears out quickly and, as a result, breaks down due to the fact that it was incorrectly installed. If you are not sure that you will be able to independently mount the equipment in accordance with the manufacturer's technical requirements, then it is better to entrust this matter to professionals. This will save you a lot in the future.

Construction tool

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.

Some features of Baxi brand boilers baxi malfunctions and repair

The main advantages of the aforementioned equipment are versatility, workmanship and a good level of automation. The appliances of this brand are excellent for providing heat to industrial premises, office buildings and residential buildings.

Positive features malfunction of the baxi gas boiler

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 adaptability 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.

Frequent boiler malfunctions baxi boiler repair basic malfunctions and remedies

You must be prepared for the fact that during the operation of the equipment, malfunctions of the Baksi boiler may occur. This may be due to non-compliance with the installation technology or the rules for operating the device. In some cases, the use of a low-quality coolant leads to malfunctions. In order for the owner of the house or apartment to be able to eliminate the cause in the event of a malfunction, it is issued in the form of a code on the display.

Below are some of the most common faults. Thus, error 01E indicates that the hardware has overheated. 02E indicates a low water level in the heating system. This error can also occur when the flow sensor circuit is broken. If there is no flame signal, you will be able to see 03E on the display. A false flame message is indicated by a combination of numbers 04. 05 indicates an open circuit in the temperature sensor. If there are malfunctions of the Baksi boiler, then in most cases you will be able to eliminate them yourself. However, you should not start work if you cannot correctly determine the cause of the problem.

Elimination of problems in the functioning of equipment repair of baxi boilers baxi with your own hands

Experts advise that when a certain error code appears, contact a company that can fix problems or advise on operating issues. However, some owners are able to independently identify the malfunction, and then bring the gas boiler into working condition.

Error 01 baxi eco four trouble codes

Malfunctions of the Baksi boiler can be indicated by the above-mentioned combination, which occurs most often. Acts as a common cause of reduced flow or blockage in the heating system. You can see this error even if the circulation pump fails. In order to fix the problem, it is necessary to analyze how correctly the heating system works. The filter should also be checked, air can get stuck in it, if necessary, it will need to be removed.

A malfunction of the Baxi gas boiler can occur when the impeller of the circulation pump has been damaged.

Error 02 baxi troubleshooting gas condensing boilers

In the presence of such an error, warm water can flow out of the hot tap for a few seconds, and then cold water. On the remote control, the temperature rises to the maximum limit, and then drops sharply. The owner of the equipment may note that the heating system is working normally.

The cause of the error do-it-yourself gas boiler repair tips and rules of work

Troubleshooting If you want to repair Baxi boilers with your own hands, when the above error occurs, it may be necessary to adjust the pressure. Experts advise getting rid of air that interferes with the operation of the system. You should check the coil resistance of the pumping equipment and also consider the impeller, the latter of which may have some damage. Experienced users are advised to open the control valve of the equipment, as well as disassemble the sensor housing, which will allow cleaning the flag.

The aforementioned Baxi Eco Four trouble codes occur in most cases due to the fact that an airlock has been created, which is located in the hot water system. The water in the circuit heats up as required by the system, however, after the plug enters the heat exchanger, the temperature rises to the maximum, which leads to the above error.

Error 10 You can easily repair gas boilers with your own hands. Tips and rules of work are collected in the article. If error 10 appears on the display, the fan may have been malfunctioning, kink may have occurred, or the tubes may have been incorrectly connected. Experienced users emphasize that a clogged chimney leads to this error. If there are strong gusts of wind outside, the malfunctions mentioned above may occur. In this case, sometimes it becomes necessary to replace or repair the fan. You can check and clean the chimney on your own. More experienced craftsmen will analyze how correctly the pipes that go from the air sensor to the fan are connected. If there are kinks, then get rid of them.

Error without code If the display does not show an error, but you hear a hum and noise that may occur when hot water is turned on, this may be due to the fact that the heat exchanger is clogged with impurities of a low-quality heat carrier. In this case, you can get out of the situation in one of two ways. The first involves dismantling and cleaning the heat exchanger, while the second involves its complete replacement.

Error 011 Baxi brand devices are very common on the heating equipment market today. You can do the troubleshooting (gas condensing boilers in mind) yourself. If the above error appears on the display, then this indicates the filling of the heating medium.

Conclusion If you decide to purchase Baxi brand boiler equipment, then, according to users, you will not regret it. Most consumers rate the devices produced under this brand positively. However, it should be borne in mind that during the operation of such boilers, certain malfunctions may occur. You can cope with them on your own if you get serious about the matter.

Repair of solid fuel boilers

The main reason for the breakdown of Baxi solid fuel boilers is their improper installation. and the use of substandard antifreeze. The burner may fail, which is noted in the absence or improper maintenance of equipment. When a homeowner uses water or poor-quality antifreeze as a coolant, corrosion of metal elements can occur. Most often, heat exchangers fail, the repair of which consists in replacing them.

The main reason for boiler breakdowns is improper installation of equipment

In case of problems with the chimney for boilers equipped with automatic control systems, the signal "Insufficient draft" appears, after which the electronics turns off the equipment. In this case, it will be necessary to check the condition of the chimney and the presence of draft in it, as well as to clean the combustion chamber from soot and soot.

You can eliminate mechanical problems, including replacing the heat exchanger or repairing damage to the chimney yourself, which will save on contacting the masters from the service centers.

But if there are problems with the control automation, then it will be impossible to fix the breakdown on your own.
