This section lists some trouble codes along with the corresponding troubleshooting steps that the user can perform to get the equipment working again.
If after this the equipment does not start working, call a specialist from the service department.
⚫ Insufficient pressure in the heating system
⚫ Explanation: The heating system needs to be topped up with water. If the error repeats over time, there is a leak.
The problem may be either in the boiler (for example: the expansion tank is faulty) or in the heating system pipeline.
Check the pressure in the heating system, inspect the pipelines to understand where the leak is.
⚫ Loss of flame
This error means irreversible blocking of automatic ignition and cessation of gas supply through the gas valve, i.e. LOSS OF FLAME. Such a blockage can occur in cases where, being in the open gas valve mode, the ignition automatic system does not receive a feedback signal about the presence of a flame from the ionization electrode.
The boiler will turn off and error F1 will appear on the display. This malfunction can also be caused by the activation of safety elements - an emergency thermostat or a combustion products thermostat. Low gas pressure at the inlet, incorrect electrical connection (phase and zero are reversed) can also cause loss of flame. To clear the fault, press the RESET button (Fig. 1, item 5). If the fault cannot be resolved using the RESET button, contact your service organization.
⚫ Explanation: Most often it means that the gas is not connected, less often it means overheating. If the boiler does not hold the flame when ignited, check that the boiler is plugged in correctly. In most cases, it is enough to switch the plug to the other side.
⚫ Malfunction of the heating water temperature sensor
⚫ Description: Indicates a malfunction of the boiler temperature sensor or a decrease in the coolant temperature below 3 °C. The boiler will be blocked, since switching on at a temperature below 3 °C is not permissible due to the possible formation of ice. Contact your service organization.
⚫ Explanation: Incorrect sensor readings can cause this error. Most often this means that the sensor needs to be replaced. It is necessary to check the sensor circuit; if it is faulty, replace the sensor.
Often this error occurs when starting the boiler in the cold season, when the water temperature in the system has dropped below 3 °C. To start the system, it is necessary to increase the temperature of the coolant in the boiler.
⚫ Boiler overheating
⚫ Description: Signals that the coolant temperature is above 95 °C. The boiler will shut down. After the coolant temperature drops below 95 °, the boiler can automatically resume operation.
⚫ Explanation: If the water circulation in the system is disrupted, overheating may occur. It occurs more often in high-power floor-standing boilers. It is necessary to eliminate the cause of overheating and restart the boiler. The thermal fuse may need to be reset.
⚫ Malfunction of the DHW sensor
⚫ Description: The boiler will stop working to heat the boiler. This malfunction does not affect the heating mode.
⚫ Explanation: Incorrect readings from the DHW sensor can cause this error. Most often this means that the sensor needs to be replaced. Check circuit/replace sensor.
⚫ Malfunction of the outside temperature sensor
⚫ Description: The boiler operates without restrictions, but the coolant temperature is regulated by the boiler sensor. If the boiler is not operating in equithermal mode, such a message cannot appear.
⚫ Explanation: First of all, check the circuit - is it connected, is there a break. If everything is in order, replace the sensor.
⚫ Wall-mounted gas boilers of the Leopard series

If after this the equipment does not start working, call a specialist from the service department as soon as possible.
⚫ Insufficient pressure in the heating system
⚫ Description: Drop in pressure of circulating water in the system (below 0.7 bar). The boiler switches off automatically.
⚫ Explanation: Increase pressure hot water in the heating system to a value in the range of 1 - 2 bar. After adding water to the heating system, the boiler will automatically resume operation. If the water pressure in the heating system drops or increases again, call an authorized service center.
⚫ Loss of flame
⚫ Description: The flame went out as a result of the gas supply to the boiler being interrupted
⚫ Explanation: Turn off and after a short pause turn on the boiler again using the main switch (RESET). If the problem persists, call an authorized service center.
⚫ Heating water sensor malfunction
⚫ Description: The boiler cannot continue operating because There is no information to what temperature the water is heated.
⚫ Explanation: Check the temperature sensor circuit. If there is no break or short circuit, then the sensor must be replaced. Contact customer service.
If the problem still persists after this, contact a qualified technician for help.

What can I do to make it work again? Answer: Error F8 - gas valve malfunction. It may have failed and needs to be replaced with a new one. Question: The hot water pressure is jumping. Those. washing and taking a contrast shower are the same thing.
Attention
We didn’t find any specialists. How to deal with this? Answer: Most likely, you have a well. The same thing happened on this and the other boiler. Everything was decided simply. First you need to check the pressure in the hydraulic accumulator (blue or red tank), it should be about 1.5 bar, if less, then pump it up.
If water starts running when you press the valve, then the internal membrane needs to be replaced. After we have checked all this, we check whether the pressure also drops. If yes, then the pressure relay needs to set the pump shutdown threshold to a higher pressure.

- Maybe, control board is faulty and it needs replacing.
f62
Error f62. Gas valve is faulty.
What needs to be done.
Czech heating equipment trademark famous for its reliability. Practitioners say: if the Proterm Leopard series boiler malfunctions and error f1 appears on the display, the problem that caused it can often be fixed independently, without calling a service technician. The article explains in detail what should be done.
Wall-mounted boiler Protherm Leopard
- If any error is displayed, not just code f1, you should not immediately look for the cause of the malfunction. The first thing to do is to restart the boiler (REZET switch). In 85% of cases, its performance is restored.
- If the fault code appears again, you should check the set parameters. Incorrectly “clogged” power of Proterm Leopard often causes error f1.
- During the initial start-up of the boiler, it may be caused by phase reversal. The wall-mounted Proterm is connected to the 220/1f network, and if “0” and “F” are mixed up, its automation will generate an emergency signal. You need to remove the plug from the socket, turn it 180 0, insert it and repeat the start.
Probable causes of error f1 Proterm Leopard
In the manufacturer's instructions, this is interpreted as the disappearance of the flame. There are several reasons for its attenuation (disappearance).
Problems with gas supply
- Check the supply of “blue fuel”. You can check that it is not blocked by looking at the stove in the kitchen. If it doesn’t “start”, for a private building it means one thing – the shut-off valve installed on the pipe has tripped. You need to move its lever to its original position and try to start Protherm Leopard again.
- Check the pressure in the supply line. When its value is below critical for the boiler, the Leopard automation prohibits starting, but gas stove it won't have much impact; only the length of the flames will decrease slightly. At facilities where cylinders are used to operate Proterm, the pressure is controlled by a pressure gauge on the reducer. When the “blue fuel” is exhausted to the minimum permissible level, the tank must be replaced, and error f1 will disappear when the Proterm boiler is restarted. If it is connected to the main pipe, this code may appear on the display due to contamination of the gas filter mesh.
Fan failure
Before removing the boiler casing, you need to check the warranty expiration date using your passport. The instructions for Proterm Leopard (clause 14 of the “Introduction” section) say under what conditions the manufacturer’s obligations are canceled. This means that any maintenance or repairs will have to be paid for.
Wall-mounted boiler diagram When the voltage is turned off, the fan blades should rotate easily. Failure (winding combustion, shaft deformation, bearing problem) is a rare occurrence. As a rule, error f1 of the Leopard boiler appears due to a break in the fan motor power supply line, poor contact or triggering of the temperature sensor
In the latter case you need:
- check the position of the reset button: it is on the sensor body (located in the upper part of the boiler, under the casing). If, after pressing and restarting Proterm, error f1 appears again, then the problem is most likely in the chimney;
- evaluate cravings. Perhaps the smoke exhaust channel is clogged with debris or small birds: there are enough options for the Leopard boiler to generate error f1.
The ionization sensor did not work
- Check the integrity of the signal line and the reliability of the wire connections.
- The cause of error f1 Proterm Leopard may be a dirty electrode. Cleaning is easy.
- If there is excessive humidity in the room, then the boiler cavity must be dried. You cannot use an open flame - only a hair dryer or something similar (fan heater, supercharged heater). The cause of error f1 may be moisture on the electronic board or the sensitive element of the sensor.
Overheat
The activation of the heating circuit thermostat is explained by a sharp decrease in the coolant circulation rate. In this case, there are several reasons causing error f1 on the Proterm Leopard display:
- failure, incorrect operation of the pump - oxidation or deformation of the shaft, impeller;
- clogged filter or primary heat exchanger of the boiler;
- leakage in the system, heating radiators, expansion tank;
- a problem with the temperature sensor signal line (short circuit) or its failure;
- lack of “visibility” between the thermostat and the control board (you need to check the reliability of the connectors).
Other reasons - failure of the ignition transformer, breakdown of the gas fittings, malfunction in the electronic module - cannot be dealt with on your own. If all of the above recommendations for eliminating error f1 Proterm Leopard positive result If they didn’t give it, you need to contact the service center.
