Beretta gas boilers have proven themselves as a source of thermal energy in autonomous heating systems. The units are equipped with a self-monitoring function for the processes occurring in units and parts during boiler operation. Equipment malfunctions can be identified by light signals.
We will analyze the typical malfunctions of the Beretta gas boiler and their elimination. Let's consider in what cases it will be possible to solve the problem on our own. Let's find out when you will have to call a gas service technician for repair operations.
We will talk about how to identify an error in the operation of the equipment, about which it independently warns the owner. We'll tell you what the combinations of letters and numbers that appear in the event of a problem with the built-in display or indicators mean. With this information, you can decide how best to proceed.
Common failures of Beretta boilers
According to gas technicians involved in the repair and adjustment of Beretta gas boilers, there are several main malfunctions that most often occur in equipment of this brand:
- There is no flame on the burner, resulting in the equipment being blocked. This problem can be caused by several reasons, ranging from a blockage to a lack of gas supply.
- Control board failure. Occurs due to the accumulation of condensation on the board, which leads to its failure. Also, board failure can occur due to burnout of parts on it.
- Increased flue gas pressure. Such a failure can be caused by ice in the chimney of a gas boiler, clogging with soot, or increased wind force. As a result, the operation of the equipment is blocked.
- Self-diagnosis sensor failure. It also causes the control system to shut down the equipment.
- Low water pressure when supplied to the heating circuit. The most common cause is a leak or problem with the expansion tank.
Statistics collected by experts do not mean that exactly such problems will occur in every Beretta boiler.
It is possible that problems will not appear at all for a long time, or completely different failures will occur for other reasons. Each problem or failure in Beretta gas boilers has its own code, which is displayed by the control system on the LCD display.
It is necessary to pay attention to failures and malfunctions during the operation of the Beretta gas boiler and correct them in a timely manner in order to avoid more serious breakdowns
Fault detection occurs thanks to a self-diagnosis system, which allows you to instantly identify problems when they arise and take appropriate measures.
Repair the board or replace it with a new one?
The electronic board of any boiler is an expensive device and replacing it with a new one in case of any malfunction is not advisable, especially since Beretta boards do not have the most complex circuit diagram.
We offer our clients board repair because it is, first of all, profitable, since the cost in most cases does not exceed 30% of the price of a new board. To carry out repairs, we have professional equipment, diagrams, original spare parts and experience.
To carry out diagnostics, special stands have been organized that simulate a real unit, on which the boards are checked after repair.
We don’t just repair boards, but we provide a significant warranty period for the work, because we have already repaired more than one such board and are confident in the result.
How does the self-diagnosis system work?
In Beretta boilers, the self-diagnosis system consists of a network of monitoring sensors located on the main working units of the units.
After turning on the boiler, the sensors begin to function in continuous mode; they do not require an additional special start. Using the same principle, it is impossible to disable the sensors without stopping or blocking the gas boiler.
All main components of the Beretta gas boiler contain sensors that send signals to the display with an error code when problems are detected
When the monitored parameters change or the operation of a particular unit is disrupted, signals from the sensors are sent to the control module, which blocks the equipment. At the same time, an error code is displayed on the display, allowing the boiler owner to determine the type of problem and take measures to eliminate it.
In addition to the display, malfunctions in Beretta boilers are signaled by special indicators located depending on the design features of different models of heating equipment.

Re: Beretta 2012 boiler - error AO1
SOS. I have a Beretta City 24 CSI boiler. The boiler only works for 2 months. After calling the master, the board burned out - the board was replaced. But . The boiler stopped maintaining the temperature - it is always in the “swing” mode. The temperature reaches the set 55 and immediately drops to 30 degrees, freezes for 2-3 minutes and starts all over again. The batteries do not have time to heat up. What could be the reason?
Error codes on the boiler display
The LCD display, which is equipped with almost all models of Beretta gas boilers, displays information about the operating mode of the equipment, as well as error codes and malfunctions that arise during operation.
Most failures are resolved by rebooting the boiler. But if the problem does not disappear after rebooting, you need to check the parts and components listed below.

A01 does not appear constantly, but periodically . Is this the problem with the board? Is it possible to repair it? There is a stabilizer.
Repairing the board is possible, but in order to find out whether the board is at fault or not, you need to know whether the fault can be cleared and at what point in the operation process the fault occurs. It happens that the pressure switch is to blame, and sometimes there is not enough gas in the line.
What do the indicator signals mean?
In some models of Beretta gas boilers, for example Beretta City, the occurrence of malfunctions in the operation of the units can be judged by the signals of the red, yellow and green indicators.
The indicators are two or three light diodes located on the central panel, which begin to blink with different intensities when a particular failure occurs.
In some models of Beretta gas boilers, signals about errors and malfunctions are provided by light indicators located on the control panel
A blinking green indicator may mean the following:
- 1 time/3.5 sec - the equipment is switched to standby mode, the fire is extinguished;
- 1 time/0.5 sec - the boiler is stopped due to a breakdown;
- 1 time/0.1 sec - the unit is switched to the auto-regulation system;
- the indicator is on and does not blink - the boiler is working normally, the fire is burning.
Beretta City can stop on its own due to a breakdown if it receives a signal from pressure and smoke sensors.
The boiler may pause operation for 10 minutes, during which the correct parameters must be restored. During this time, the system will automatically scan. A detailed guide on how to check the sensor readings of a Beretta gas boiler should already be included in the self-diagnosis system.
The indicators on the Beretta boiler panel can produce signals in different combinations and with different intensities. The type of light signal depends on what error occurred during the operation of the unit
The red indicator turns on in the following cases:
- the indicator is on and does not blink - if after stopping the boiler operation is not established, the unit goes into emergency mode;
- the indicator is flashing - the limit temperature sensor is triggered. Sometimes you can eliminate the error using the operating mode switch.
Simultaneous flashing of the red and green diodes occurs in the event of a breakdown of the NTC sensor.
The yellow indicator lights up and stays lit when preheating of the coolant in the circuit is turned on.
If you are not confident in your abilities and knowledge, it is strongly recommended to invite a qualified specialist to repair your Beretta gas boiler
To eliminate all the above-described problems with Beretta gas boilers, it is strongly recommended to use the services of specialists from authorized service centers and organizations with which an agreement has been concluded for the maintenance of gas units and the supply of blue fuel.
Independent intervention in the complex design of boilers can lead to an even more serious breakdown, which will result in expensive repairs and a long shutdown of the autonomous heating system.

Re: Beretta 2012 boiler - error AO1
The alarm is cleared when switched to off mode and back to DHW. An accident occurs when you turn on hot water, just turn on any faucet in the house to hot and A01, but not every time after 3-5 times. The alarm is cleared when switched to off mode and back to DHW. Yesterday the A01 alarm popped up 2-3 times in a row. I barely ran hot water. When I turned it on, the hot water runs normally and takes a long time to fully heat up. But it turns out to be a lottery to launch) Maybe take off the lid and look at something else? What to look for?

Re: Beretta 2012 boiler - error AO1
There was a master who installed the boiler. Since the boiler had been working for 5 years, I blew out and washed everything that could be blown out and washed. I was sure that the pressure sensor was to blame. We replaced the boiler, turned on the water three times, heating approx. At 4 again A01)) further suspicions about the board and stabilizer. We have a private sector, an old area, power surges due to 2 home service stations nearby. I agreed with the master that I would buy a voltage relay and install it to check the output stabilizer to see if it is allowing surges. I checked the stabilizer and it gives 210-225V during surges. The cut-off relay may work 1-2 times a day. But the error pops up more often. I even tried trying on a different stabilizer, but the error keeps popping up every once or twice. So the problem is with the board? Should I change the relay on the board? The boiler starts up, hums, all stages go until ignition and the boiler should start flaming when an error pops up. A couple of times it has already happened that it didn’t get to ignition: it’s humming (the fan and the pump probably) but the error doesn’t pop up, the water goes on and on, the temperature drops down because the heating didn’t start. Could it be something with the lighter?
