Beretta Gas Boiler Error Codes have proven themselves as a source of thermal energy in autonomous heating systems. Units are equipped with a function of self-monitoring of the processes occurring in components and parts during operation of boilers. You can find out about equipment malfunctions by light signals.
We will analyze the typical malfunctions of the Beretta gas boiler and their elimination. Consider in what cases it will be possible to solve the problem on their own. We will find out when for repairs it is necessary to call a master from the gas service.
We will talk about how to determine the error in the operation of equipment, about which it independently warns the owner. Let me tell you what the combination of letters and numbers that occur in case of a malfunction on the built-in display or indicators. With this information in mind, you can decide what to do best.
Beretta Boiler Error Code Solutions
Beretta Boiler Error Code A01
It means that there is no ignition. The ionization flame sensor indicates a malfunction of the boiler. Such a component recognizes the presence of a flame and blocks the operating functions of the Beretta boiler in case of limited combustion of the main gas burner device or in case of gas supply problems. Blocking occurs after 3 unsuccessful launches. To resume operation, it is recommended to press and hold the R button. Gas valve problem – The gas valve is controlled by the electronics. This component is tested by measuring resistance and voltage. If it is found that the values differ from the nominal parameters, it is required to change the valve to a new one. Lack of gas inflow to the device A valve is placed in the gas distribution circuit, which can close the gas inflow.
As a consequence of this, failure to start the unit may occur due to a blocked valve. Poor contact or no pulse from the flame control sensor. Faulty electronic board – If the ignition is correct, but the device immediately extinguishes anyway, then the electronic board is probably unable to detect the flame. In this case, it is recommended to test it. Problems at the time of ignition. This occurs if there is no ignition or there is a separation of the flame. Diagnosis should be made of the connections between the ignition unit and the flame sensor, and also between the electronic board and the gas valve. One of the factors for flameout may be a lack of thrust. Faulty electronic board – If the ignition is correct, but the device immediately extinguishes anyway, then the electronic board is probably unable to detect the flame. In this case, it is recommended to test it.

Beretta Boiler Error Code A02
Overheating of the Beretta boiler. The device is blocked. The overheat protection thermostat has switched on – The overheat thermostat, like the temperature sensor, is mainly located on the outlet pipe of the primary heat exchanger. The main purpose of the thermostat is to protect the boiler unit from high temperatures. An emergency situation may arise due to problems with the thermostat, temperature sensor, and in addition, if the main circulation circuit fails. Faulty temperature sensor – The control board receives an incorrect signal or poor contact between the sensor and the control board.
Breakdown of the overheating thermostat – If the thermostat is suitable for operation, although an actual overheating of the liquid is detected, then, apparently, there has been a violation of the circulation of the coolant of the main circuit. Blockage of the primary heat exchanger or filter element of the heating circuit (insufficient circulation process implies high heating of the liquid). The circulation pump is out of order or there is a blockage from the air in the heating system.
Beretta Boiler Error Code A04
It indicates low pressure inside the system. The main sources preceding this malfunction: a decrease in coolant pressure in the heating circuit. There is no contact between the electronic board and the relay-sensor. The pressure switch is faulty. Initially, you need to know the values \u200b\u200bof the pressure gauge. In many cases, the problem can be corrected with a make-up valve that is designed to add fluid to the system. In the event that a repetition of the emergency occurs, then there is probably a coolant leak. The hydraulic pump, primary heat exchanger, excess pressure relief valve, worn gaskets, make-up valve and other parts may be leaking. A leak can be detected during an external inspection of the hydraulic components.
Beretta Boiler Error Code A03
Insufficient traction. In order to ensure the correct and stable functioning of the Beretta boiler, it is necessary to organize a draft for the removal of exhaust gases so that they do not enter the living quarters. The outlet of gases is controlled by automatics, and if some problems arise, the draft sensor will turn on and the boiler will stop working. The main factors in which there is a lack of traction: a small-sized diameter of the discharge channel, a design flaw, pollution, ice on the inner wall.
Reducing the diameter of the discharge channel can cause a lack of traction. The flue pipes are too long It is recommended to carefully read the instructions for use of the gas boiler and check that the mandatory requirements are complied with. Too long a horizontal section of the smoke exhaust pipe causes a weakening of the necessary draft. Draft sensor malfunction – When a vacuum is created in the supply tube, a characteristic click can be heard. Poor contact of the control board with the draft sensor, condensate in the tubes, as well as incorrect connection of the tubes to the pneumatic relay. Fan stopped – There is a blockage in the fan impeller. The fan shaft is not lubricated, which is why it has low speed. Lack of contact between the fan and the electronic board.
Beretta Boiler Error Code A06
Problems with determining the temperature of the DHW sensor. This code indicates that the DHW temperature sensor has broken or the operating temperature has risen.
The main sources preceding this malfunction: the hot water temperature sensor is damaged. There is no contact between the DHW temperature sensor and the control board. Electronic board defective. If the hot water temperature sensor is working and is in stable contact with the electronic board, although at this moment the unit gives an error, then the electronic control board is probably out of order.
Beretta Boiler Error Code A07
The heating system temperature sensor is not working properly. This code indicates a malfunction of the temperature sensor in the heating circuit or the recommended temperature has been exceeded. Damage to the heating circuit temperature sensor circuit – Such a malfunction occurs when the contact of the temperature sensor with the electronics board is interrupted, or the temperature is below normal. After 5 seconds, following the detection of a malfunction, the Beretta boiler will restore normal operation, if the malfunction occurred spontaneously.
It is necessary to check that there is no moisture on the sensor connector and the control board connector. If there is no moisture, the temperature sensor must be replaced. There is a short circuit in the heating circuit temperature sensor – This problem may occur at the time of a short circuit in the temperature sensor circuit or the temperature value of the liquid is above normal. First you need to measure the resistance of the temperature sensor. If the resistance values do not match the required ones, the sensor should be replaced. When replacing the temperature sensor does not help, replace the control board.
