Italian gas boilers Ferroli have excellent characteristics, and if there are any problems, they will definitely signal an error code on the display. Faults are encoded with an alphabetic and numeric value.
If it is "A", then the automation is triggered, which forcibly shuts down the equipment. If there are errors marked "F", the boiler continues to function, but you should not ignore the problem, as there is a development of a more serious breakdown.

The most common mistakes
The Ferroli gas boiler, depending on the model, can simultaneously generate several errors that are interconnected. In this case, you need to call the master and conduct a comprehensive diagnosis. The problem is not always solved by rebooting the equipment, it may be necessary to replace individual parts.
A01
The problem is related to the impossibility of ignition.
There are several reasons for this:
- There is no gas supply - the valve valve on the pipe is closed, or there is no gas in the system itself.
- The pipeline is airy - often happens when the heating system is first started.
- Gas valve malfunctions - factory defects or deterioration of the element, which causes an emergency shutdown of the boiler.
- The ignition power is insufficient - it does not correspond to the indicators fixed in the technical specifications.
- Wrong angle between the electrode and the burner - does not allow ignition.
- The electrode is covered with soot and soot - there is no necessary conductivity.
- The injectors are set incorrectly.
- Too low pressure (less than 20 mbar) - the ignition process is blocked.
- Problems with the central control board - arise due to power surges in the network.
Error A01
The error is manifested by the impossibility of full ignition, or the boiler goes out spontaneously after 5-7 seconds. You can only check the presence of gas in the system on your own, or make sure that the gas supply valve is open. Further actions are performed only by the master, who will inspect the boiler and diagnose possible malfunctions.
The repair will focus on:
- Restoring the desired pressure in the system, as well as adjusting the nozzles in accordance with the manufacturer's requirements.
- Replacement of the electrode pair or their cleaning from strong contamination.
- Replacing the gas valve, since in most cases it cannot be repaired.
- Setting the correct angle between the electrode and the burner.
If the problem is in the board, then it will be replaced with a new one. After the repair is completed, the boiler is restarted and the result is evaluated.
A02
A false signal is generated, which indicates the presence of a flame when the burner is off. The operation of the boiler is blocked, re-ignition is not possible. A common cause is a malfunction of the central control board. Indirect causes are a break in the contact in the wire that connects the board and the electrode, as well as an incorrectly set angle between the burner and the electrode.
It is impossible to fix the error on your own, since there is a need to open the gas equipment and inspect all the elements of the combustion chamber. The payment is checked first. If there is even the slightest suspicion of a malfunction, a new one is installed.
A03
The error occurs when the boiler overheats when the water in the circuit exceeds 90℃. For the Ferroli Domiproject C24 model, the temperature sensor is triggered at a temperature of more than 105℃.
This occurs in such cases:
- Malfunction of the temperature control sensor itself - open contacts, short circuit, oxidation at the junction.
- Voltage instability in the mains - it is below or above the norm, and there is no stabilizer.
- Pump malfunction - the coolant stops driving, which leads to overheating of the boiler, while the batteries are cold.
- Airiness of the system - air warms up faster than water.
- Low pressure in the heating system - there are leaks, or the make-up valve is not closed.
- Problems with the expansion tank, including airiness.
You can do only 3 things on your own: check the pump is working properly, bleed the air from the batteries and fix the voltage in the network.
Further work is carried out by the master:
- Removing and checking the health of the temperature sensor.
- Monitoring the operation of the pump, its replacement in the presence of a malfunction.
- Evaluation of the operation of the expansion tank, its purging and pumping out with a pump.
- Leak detection and other reasons very low pressure in the heating system.
First of all, the boiler is allowed to cool, after which they proceed to the inspection.
A06
The code appears when the flame goes out some time after ignition.
The reasons may be:
- Insufficient pressure in the gas supply system - gas can be shut off.
- The nozzles are not adjusted, the gas pressure in them is insufficient.
- Soot and soot on the electrode, its burnout.
- Creating a reverse draft in the room, or the fan spontaneously extinguishes the flame.
- Malfunction of the central control board.
Diagnostics is carried out by the master, who first of all evaluates the performance of the nozzle and electrode, and also adjusts the distance, if necessary. Further, the smoke exhaust system is subjected to revision, after which the work of the central board is evaluated.
A21
The error is associated with a malfunction of the combustion control system, in which the boiler ignites and goes out a large number of times in a limited period of time.
The reasons are:
- No draft in the chimney - the chimney may be clogged, or there is icing.
- Malfunction of the sensor itself - oxidation and wire breakage, short circuit.
- Lack of correct gas valve setting – performed with special equipment.
Only a master who has permission to carry out repair work in gas equipment will help in solving the problem.
F05
After starting the boiler, the fan does not turn on automatically, which may occur for the following reasons:
- Fan failure - breakage or oxidation of wires, short circuit.
- Chimney blockage – the exhaust gas does not escape to the outside.
To fix the problem, you should remove the fan and check it for operability.
F20
The problem occurs with various malfunctions of the central board, which can be triggered by both voltage drops in the network and burnout of individual contacts.In most cases, the problem can be solved solely by replacing this part with a new one.
Errors marked "D"
Technically, these codes are not a significant error that adversely affects the performance of the boiler.
They point to the following:
- D1 – delay before the next switching on of the boiler. The code often occurs when you force a hardware reboot.
- D2 – waiting time for the next water heating cycle.
- D3 - the waiting time before the next ignition, when there is a need to re-ignite the boiler, if it did not work out the first time.
- D4 – forced pause between launches (about 5 minutes).
Relatively rare error codes
If the gas equipment is worn out or its service life is more than 10 years, then the following atypical error codes may be displayed on the display:
F39 - malfunctions in the thermistor, which are eliminated by replacing the wiring or stripping oxidized contacts.- F40 – high pressure in the system. Problems with the expansion tank or a blockage in the quick release valve.
- F43 - operation of the heat exchanger safety system, which may indicate the airiness of the system, or a malfunction of the pump.
- F50 - malfunction of the gas fittings, which may cause damage to the board, as well as the valve. For diagnostics, a forced reboot of the boiler is used.
Sometimes the display shows several codes at once, which indicates a serious breakdown in any one segment, or adjacent and interdependent. It is not recommended to constantly reboot, as this will not solve the problem, but only delay it for a while.
General advice and recommendations for the correct operation of Ferroli boilers
To reduce the risk of breakdowns, it is enough to follow simple but effective tips:
- Do not use a faulty boiler if the codes appear on the display constantly. You need to call the master.
- Be sure to connect the boiler to electricity through a stabilizer. This brand is vulnerable to fluctuations, from which the board suffers.
- Annually undergo preventive diagnostics, and also do not forget to clean the heat exchanger from scale.
- Control the pressure in the system and do not forget to close the make-up valve.
- Do not use the boiler at full capacity. If it is not enough to fully heat large areas, you need to choose a more powerful model.
Never use faulty gas equipment, as it is life threatening. In the event of breakdowns, you cannot open the boiler yourself, and even more so repair individual parts. Only a licensed specialist is authorized to carry out this kind of work.
Questions and answers
Check if the hood is clogged, especially if the problem occurs in winter. Frost can cause blockage, which prevents the full removal of exhaust gas. In any case, it is better to call the master and check the ventilation duct.
This process is not a mistake. You can also skip it by clicking on a combination of the corresponding buttons.Do not unplug the boiler from the socket unnecessarily, then all settings will be saved and the boiler will start up faster.
Try connecting the boiler through a voltage stabilizer. The problem is especially common among residents of apartment buildings. If it does not help, then you need to call the wizard. Ignition should not cause strong popping.
In conclusion, it is worth noting that Ferroli gas boilers also encounter breakdowns and malfunctions, which are recorded in the form of code values. When they appear, you need to call a specialist to diagnose and fix problems. Otherwise, the boiler will be faulty and its use dangerous to life.
