Malfunction of gas equipment in modern boilers is coded with certain digital and letter values. Such codes allow you to determine what exactly the problem is and quickly fix it. Proterm gas boilers differ in the type of ignition, installation method and number of circuits.
But faults in the form of codes have a common interpretation. The technical manual will often indicate possible problems for a specific boiler model. Let's look at the most common errors, the reasons for their occurrence and ways to eliminate them without calling specialists.
Proterm Jaguar boiler errors Leave a comment
The wall-mounted gas Protherm Jaguar is available in three versions that have no fundamental differences. Consequently, the reasons that cause errors on the display of any of the boiler modifications are identical. Most problems can be resolved by the user, but the factory instructions for Proterm Jaguar do not provide recommendations, but only indicate a probable malfunction and advise you to contact a service center. The article will fill the information gap and help you figure it out on your own.
The appearance of an error on the Proterm Jaguar display is often caused by problems with the supply voltage: low value, instability, sudden jumps. Before looking for a fault, you need to reset using the REZET button on the front panel of the boiler. Typically the code disappears.
Doesn't start
reasons why the boiler . The simplest one is that the power cable is not connected correctly.
Protherm boilers are phase-dependent, i.e. the phase must be connected to a specific electrode.
The same requirements apply to the “zero” and “ground” electrodes. The problem can be solved simply - you need to turn the plug over in the socket, or swap the electrodes if the design of the plug does not allow you to change its position.
Other reasons for the inability to start the boiler may be:
- No voltage in the network.
- No or extremely low gas pressure.
- Failure or breakdown of automation (control board),
- Short circuit of one of the sensors that can block the device.
All these reasons can block the launch and hold the problem until it is fixed. The search must be carried out in stages, from the simplest to the more complex reasons.
F01, F08.
Overheating is the most common error, typical not only for gas Proterm Jaguars. In 80% of cases it is caused by external factors; There is no need to remove the unit casing and repair it. This means that the warranty on the boiler will not be violated if the problem is fixed. This error is a consequence of a sharp slowdown (or cessation) of coolant circulation. As a result, the temperature of the liquid in the heating circuit rises to the maximum permissible value: the Proterm Jaguar protection is triggered.
Probable Causes
Recommendation:
Bleed the system until the coolant flows in a continuous stream.
Recommendation:
Inspect the heating circuit throughout the house. Stains on the floor and puddles will indicate where the system has depressurized. There may also be a hidden defect that cannot be detected visually. For example, when installing pipes under cladding. In this case, you need to add coolant and systematically monitor the pressure in the circuit. Its repeated decrease and error F01 are a sign of a leak in a place inaccessible to view. It's easy to figure out where to look.
Recommendation:
Check the voltage at the terminal block, the integrity of the wires, the absence of short circuits (to the body, to each other);
Dismantle the pump and rotate the impeller: it should rotate freely. Deformation of the blades or shaft, oxidation, salt deposits are the causes of error F01 Proterm Jaguar. If it is impossible to eliminate the defects, the boiler pump is replaced.
Recommendation:
Check signal line. It is not advisable to test the sensor for functionality using a multimeter - it is easier to replace it, since the error has an unambiguous interpretation.
Recommendation:
It is not difficult to remove the device from the Proterm Jaguar boiler to assess the condition of the cavity. But washing it at home is problematic. To soften deposits, a special solution is poured into the heat exchanger. And only after standing for several hours is it washed with water under pressure.
Cleaning the Proterm Jaguar heat exchanger yourself will cost free, but the effect will be short-lived. There is a high risk that at the height of the heating season an F01 error will appear and the boiler will have to be stopped and the device serviced again. It’s better to contact a workshop - for at least a year and a half there will be no complaints about the heat exchanger.
Hot water temperature sensor. If the wires are intact, there are no short circuits or breaks, replace them.
Possible reason
Possible cause of the error is a clogged secondary heat exchanger
Recommendation:
It is necessary to carry out maintenance of the device.
Heating circuit sensor: similar to DHW (F02).
No burner flame. The Proterm Jaguar error is caused by a lack of signal from the boiler ionization sensor.
Probable Causes
Air duct problem. The combustion chamber in Proterm Jaguar boilers is closed. Therefore, during installation, a coaxial chimney is connected to them. If it is clogged (for example, with debris or wind-blown leaves), then error F05 will appear on the display. It is also initiated by poor traction - it is quite easy to eliminate on your own.
If this problem arose during the initial start-up of the boiler, you need to make sure that the chimney is assembled correctly. The error may be the result of illiterate actions of the installer, and until the errors are corrected, Proterm Jaguar is unlikely to start.
The temperature in the heating return line is above critical. The error is issued if the corresponding sensor located in the boiler is faulty - replace it.
Problem with gas fittings Proterm Jaguar.
Recommendation:
All you can do yourself is check the signal circuits. A specialist should evaluate the performance of the valve and adjust it.
The error appears due to a failure or incorrect operation of the pressure switch.
Probable reasons:
Recommendation:
If everything is fine with the electrical part, you need to turn off the power to the boiler and push the turbine impeller. Rapid stopping of the blades is a sign of a split bearing and thermal deformation of the shaft. The Proterm Jaguar error can be resolved by replacing the fan.
Problem with pressure in the heating circuit. The reasons are partially described in relation to code F01. It is necessary to bring the coolant level to normal and monitor the system. If there are no leaks and the error is repeated, the conclusion is clear: sensor malfunction.
Recommendation:
Elimination must begin with assessing the condition of the signal wires and the reliability of the contacts.
Poor coolant circulation. See error F01.
Recommendation:
Such a code on the Proterm Jaguar display indicates a difference in temperature at the outlet and inlet of the boiler over 35 C. If it appears during the initial start-up, and no other reasons have been identified, you need to evaluate the correctness of the heating circuit diagram. When independently developing a project, errors can be made in calculating the length of the route, determining the number of radiators, or when choosing their type and dimensions - there are enough nuances that trigger the appearance of the F11 code.
Problem with supply voltage. If it drops to 165 V, the following error is displayed on the Proterm Jaguar display.
Recommendation:
This can be eliminated forever by connecting the boiler to the network via a UPS.
The error is similar to F11. Appears when the temperature of the coolant at the inlet to the boiler exceeds its value at the outlet.
Probable Causes
Advice.
All other causes of Proterm Jaguar errors are caused by malfunctions or malfunction of the boiler electronics. It is useless to diagnose the board yourself: you need to contact a service center - the module is replaced. The only thing you can do is check the fuse. It can burn out if the Proterm Jaguar is connected directly to an outlet, and there are constant problems with the power supply/voltage at the facility.

Why does the pressure in the device increase?
A rise in pressure is an extremely dangerous situation, fraught with mechanical failure and even an explosion.
The liquid is incompressible; it fills the entire volume of the pipelines. If the pressure on the pressure gauge approaches 3 mbar and continues to rise, it’s time to take action.
One of the reasons is the failure of the expansion tank. When heated, the liquid expands and its volume increases by 4%.
A normally functioning expansion tank absorbs this excess interest, but if it is already full, the excess liquid simply has nowhere to go. This situation can be determined by the state of the relief valve - heating agents will constantly ooze out of it.
The main failure of the expansion tank is a rupture of the membrane. With it, water fills the tank completely, leaving no room to accommodate the expanded liquid. The solution would be to replace the membrane or the entire expansion tank.
Another possible reason is that the supply valve is not closed or has failed. Water continues to flow into the system, increasing the pressure.
It is necessary to check the condition of the tap and turn it off or replace it. You should check the condition of all shut-off valves and clean the strainer. There may also be problems with the boiler automation, which can only be resolved with the help of a specialist from the service center.
Design and principle of operation of Proterm boilers
Let's take a closer look at the most popular models from the manufacturer Protherm.
Proterm Gepard 23 MTV (MTV)
This model of a wall-mounted double-circuit boiler belongs to the middle price segment. Equipped with a function for heating liquids for household needs, device power is 23 kW. There are two modifications of the model on the market, natural (MOV) and forced (MTV) removal of the combustion product.
The operation of the boiler can be controlled using a room thermostat or an external temperature sensor. The design provides a liquid crystal display, with the help of which the operation of the device is monitored.
Cheetah 23 MTV does not need to be connected to a chimney system, since it has a coaxial smoke exhaust system, which makes it possible to install it in a room without a chimney. The built-in heat exchanger is made of stainless steel, and there is a sensor that monitors the pressure in the system.
Boiler Proterm Gepard 23 MTV
It operates in two winter/summer modes, the power is adjusted thanks to a modulating burner. The water reaches the set temperature within 3 seconds after opening the tap, the efficiency is 91%.
There is a function to protect against freezing and overheating of the system. The advantages are that they are very easy to use, do not pollute the environment during operation, and are affordable.
Proterm Lynx
The installation method is wall-mounted, the boiler is intended for heating the room and heating hot liquid. Depending on the area of the room, there are two power options: 24 kW and 28 kW. Thanks to the forced removal of combustion products, it is possible to install it in a room without an equipped chimney, or if it is not technically possible to install one there.

Boiler Proterm Jaguar
Connecting a room thermostat
A room thermostat allows you to more accurately adjust the indoor microclimate. Its sensor checks the air temperature, which gives more accurate results than checking the extract air temperature, which is produced by the boiler electronics.
Using a room thermostat allows you to turn off the boiler when the set values are reached, when the device’s own sensors are not yet ready to give a command to stop heating.
READ Installing a boiler with a closed combustion chamber
The thermostat is connected to a special gap in the control board, the contacts of which are closed by default with a jumper.
To connect the boiler , open the lid and remove the jumper. Then the room thermostat is connected in the required order and a test switch is performed.
If the device operates normally, close the lid and proceed to further operation of the boiler with additional equipment. If problems are found, they are corrected immediately.
Basic error codes
Next, we will consider the main malfunctions of the Proterm gas boiler, error codes and possible options for correcting them.
Error F1 (f1). Loss of flame, ignition is blocked and gas supply to the gas valve is stopped. This happens when the board does not receive a signal about the presence of a flame from the ionization electrode, while the gas valve is open, the protective mechanism is activated and the boiler turns off.
The cause may also be insufficient gas pressure. To eliminate this, press the reset button and check if the gas valve is open, and it would be a good idea to check the plug in the socket, turn it over, reversing the polarity.
Also, error F01 often indicates the thermostat is overheating; to fix it, try pressing the reset button on it. This problem occurs very often in the Proterm KLOM model.
Error f2 (f2). The heating circuit temperature sensor has failed, or the coolant temperature has dropped below 3 degrees. The device is locked because ice may form. Often this indicates a sensor failure; check it and, if necessary, replace it with a new one.
Heating circuit temperature sensor
However, this situation can be caused by starting the device in the winter season, when the temperature in the system is really insufficient. To start the system, increase the temperature in the system.
Error f3 (f3). This error signals that the boiler is overheating and means that the permissible critical maximum of 95 degrees has been reached, the protection is triggered and the boiler automatically turns off.
Wait until the temperature drops below this indicator, the boiler will start on its own. If this situation occurs again, reset the thermal fuse.
Error f4. The DHW sensor has failed, when this breakdown occurs, the boiler operates as usual to heat the heating circuit, and heating of the liquid for domestic needs stops. Often, such a breakdown indicates either that the sensor has failed and needs to be replaced, or that the contacts have oxidized; clean and inspect them.
Error f5. Damage to the external temperature sensor. In the event of such a malfunction, the device operates, but the temperature control is carried out by the boiler temperature sensor. To eliminate this, check whether there is a mechanical break in the boiler-sensor circuit; if there is no break, it needs to be replaced.
Boiler temperature sensor Proterm
Error f6 (f6). Indicates a break in the exhaust gas sensor. Ring the connecting wires between the sensor and the board. The board may be faulty; take it to a service center for diagnostics, or the sensor itself may be faulty. This breakdown may be caused by a faulty ignition transformer, check it.
Error f7. The instructions describe the error as a connection failure. This gap can be anywhere, and means that when connected to the controller, a signal does not arrive from one of the elements, or there is not enough voltage at the terminal on the control board.
You need to visually inspect all the wires, test them for breaks, check all connectors. It is also possible that the board itself has failed and needs repair. If you cannot find anything, seek qualified help from a specialist.
Error f8 Indicates that the NTC sensor circuit is open and the DHW boiler is grounded. Ring this circuit of connections, disconnect and reconnect these elements, as the contacts may have come loose. If these manipulations do not produce results, replace the sensor.
Error f10. Indicates a short circuit of the NTC temperature sensor on the supply line.
This fault appears on the display if:
Error f15. Short circuit of the reverse draft sensor. The combustion products controller is located at the top of the boiler, it is connected to the fan tubes.
It is necessary to disassemble, clean all terminals, and remove deposits from the tube. If this procedure does not bring results, you will need to replace it with a new device.
Error f20 (f20). The safety temperature limiter has tripped. The supply line temperature sensor may be connected incorrectly, causing the temperature to rise above the permissible limit (95 degrees) or an open circuit to occur.
Gas boiler temperature limiter
Call it, if you do not find a malfunction, try reconnecting it. Check if the pump is working properly and bleed air. If you are unable to solve this problem yourself, seek help from a specialist.
Error 22. This problem indicates low fluid pressure in the heating circuit of less than 0.3 bar.
Possible reasons for this:
Add fluid to the system. Check all elements for leaks, as pressure may drop due to a leak; if found, fix it.
Error f23. Exceeding the permissible temperature difference between the supply and return lines.
This could happen as a result of the following:
Error f24. The liquid level in the heating circuit is low, the temperature is rising very rapidly.
This may have happened due to:
Error f25. The protection system against carbon monoxide penetration into the room has been activated. Why does the boiler turn off? When this malfunction occurs, the relay contacts open due to a disruption in the air flow.
The reason may be:
Error f28 (f28). Flame goes out when turned on.
The following reasons for this malfunction are possible:
It would also be useful to clean the entire ignition group, including the burners.
Error f29 (f29). The flame goes out while the boiler is operating.
Let's look at the possible reasons:
Error f33 (f33). The anti-frost protection system in the fan is activated. The contact in the relay does not close.
Possible for several reasons:
Error f55. Carbon monoxide sensor malfunction.
You need to check the following:
Error f62. Gas valve is faulty.
Error f63. Memory board failure.
Make a selection according to the power of your boiler 1-6 kW, 2-9 kW, 3-12 kW, 4-14 kW, 5-18 kW, 6-21 kW, then click on “ok” and “plus” at the same time. Then, after a minute, turn off the boiler completely, wait 5 minutes and turn it on again.
Error f72. Difference in readings of flow and return line sensors. Every 24 hours or during startup the boiler performs a self-diagnosis (system test), this test was not successful. The boiler compares the readings of these sensors.
The reason may lie in the following:
Error f73 Indicates a non-connection or short circuit in the pressure sensor.
Error f75 (f75) Repeated malfunction in the pressure sensor. After the pump has been started five times and the pressure has not exceeded the norm of 50 mbar.
Error f83 Indicates that there is no coolant, the temperature does not increase when the burner is turned on. Airing of the circuit is possible.
Error f84. Indicates a stable temperature difference between sensors NTC2 and NTC5.
Error f85. The flow and return sensors are faulty.
How to turn it on
The boiler is started by pressing the round “main switch” button to the right of the display.
Error F04 when starting a protherm gas boiler
Power supply to all boiler systems begins. Usually the boiler is in standby mode, i.e. There is no preparation of coolant and hot water. The display shows the current state of the device, so the user can immediately determine what the boiler automation is currently doing.
To start the process, you need to set the temperature of the heating agent or hot water supply, after which the burner will start and the coolant will begin heating.
These actions will be accompanied by characteristic sounds of pump operation, water movement, and burner startup.
The boiler is stopped by simply pressing the main switch.
Other faults
Error 00
Temperature sensor malfunction (shutdown).
Connection terminals for the Proterm Skat boiler
What to do:
Error a6
It occurs due to low air temperature in the room where the boiler is installed, simply put, in the boiler room. To eliminate it, increase the temperature by installing a radiator in the boiler room.
Error f04
Indicates problems with ionization. Restart the device and see if the gas valve is closed.
How to connect to electricity
The electronics of gas boilers are demanding on the correct connection of the phase, zero and ground electrode.
If the contacts are reversed when connecting, the boiler will not start. Therefore, it is important to use a special plug and socket that does not allow you to connect the device in any other way. When running the cable, you need to check the correct distribution of the electrodes in the socket.
To check, use a probe screwdriver or other special devices.
Practical recommendations
• The Vaillant boiler should not be connected to the network directly, but through a UPS. A unit is a complex device consisting of a group of batteries, their charging and voltage stabilization circuits. Even if the power line is disconnected or the backup electric generator breaks down, the heating installation will continue to function for several hours (depending on the total battery capacity).
• The “weak link” of the pressure sensors of any imported boiler, and Vaillant is no exception, is the sensitive element (membrane). Foreign developers focus on their customers, without taking into account our specifics. This concerns the quality of the water filling the heating circuit. Over time, with increased rigidity of the coolant, the rubber rubber becomes “oaky” and loses sensitivity to changes in the pressure of the circulating liquid. In fact, the sensor (flow switch) is working, but boiler error F75 appears periodically. The reason is that the membrane does not respond to slight changes in pressure.
It is advisable to order and install a new German sensor of a new modification in the Vaillant boiler (article 0020023721). The price is quite high (around 11,500 rubles), but the warranty for it is 5 years, and the problem with the appearance of error F75 due to the “whims” of the flow switch will be solved forever. It is made in such a way that debris is excluded: special membrane material, polymer filling of voids in the sensor body.
