Malfunctions of the Beretta gas boiler: error codes, their decoding and methods of elimination

Gas boilers Beretta have proven themselves as a source of thermal energy in autonomous heating systems. The units are equipped with a function of self-monitoring of the processes occurring in the units and parts during the operation of the boilers. Equipment malfunctions can be detected by light signals.

Let's 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. We will find out when for repair operations you will have to call a foreman from the gas service.

We will tell you how to determine the error in the operation of the equipment, about which it independently warns the owner. Let us show you what the combinations of letters and numbers mean in the event of a malfunction on the built-in display or indicators. With this information, you can decide how best to proceed.

Common breakdowns of Beretta boilers

According to the gas workers involved in the repair and adjustment of Beretta gas boilers, there are several main malfunctions that most often occur in the equipment of this brand:

  1. There is no flame on the burner, as a result of which the equipment is blocked. This problem can be caused by several reasons, ranging from a blockage to a lack of gas supply.
  2. Breakdown of the control board. It occurs due to the accumulation of condensation on the board, which leads to its failure. Also, a breakdown of the board can occur due to burnout of parts on it.
  3. Increase in flue gas pressure. Such a failure can be caused by ice in gas boiler chimney, soot clogging, increased wind force. As a result, the equipment is blocked.
  4. Breakdown of the self-diagnosis sensor. Also leads to equipment shutdown by the control system.
  5. Low water pressure when supplied to the heating circuit. The most common cause is a leak or a problem with the expansion vessel.

The statistics collected by experts does not mean that such problems will occur in every Beretta boiler.

Perhaps the problems will not appear at all for a long time, or completely different failures will arise for other reasons. Each malfunction or malfunction in Beretta gas boilers has its own code designation, which is displayed by the control system on the LCD display.

It is necessary to pay attention to malfunctions and malfunctions during the operation of the Beretta gas boiler and eliminate them in a timely manner in order to avoid more serious breakdowns.

Fault identification occurs thanks to a self-diagnosis system that allows you to instantly identify problems when they occur and take appropriate action.

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 a continuous mode, they do not need an additional special start. By the same principle, disconnecting sensors is impossible without stopping or blocking the gas boiler.

Gas boiler without protective cover

In all the main components of the Beretta gas boiler there are sensors (sensors) that send signals to the display with an error code when a malfunction is detected

When the monitored parameters change or a unit malfunction occurs, signals from the sensors are sent to the control module, which blocks the equipment. At the same time, an error code is shown on the display, allowing the owner of the boiler to determine the type of malfunction and take measures to eliminate it.

In addition to the display, malfunctions of Beretta boilers are signaled by special indicators located depending on the design features of different models of heating equipment.

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 occur during operation.

Most faults are cleared when the boiler is restarted. But if after rebooting the problem persists, you need to check the parts and assemblies listed below.

Sometimes there are situations when errors are not shown on the display of the Beretta gas boiler, but other symptoms of equipment malfunction appear.

These signs include the appearance of gas or burning odors in the room with the boiler, the delayed operation of the boiler burner, as well as a noticeable difference between the heating of the boiler and the temperature of the batteries. These malfunctions should be treated with as much attention as the codes on the display.

What do the indicator signals mean?

In some models of Beretta gas boilers, for example, Beretta City, the appearance 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 LEDs located on the central panel that start blinking at different intensities when a fault occurs.

How to find a malfunction in the Beretta boiler by indication

In some models of Beretta gas boilers, errors and malfunctions are indicated by light indicators located on the control panel.

A blinking green light can 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 automatic control system;
  • the indicator is on and does not blink - the boiler is working normally, the fire is on.

The Beretta City may stop on its own due to a breakdown in case of receiving a signal from the pressure and smoke exhaust sensors.

The boiler can stop working 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 readings of the sensors of the Beretta gas boiler should already be laid down in the self-diagnosis system.

Indicators on the panel of the Beretta boiler

The indicators on the panel of the Beretta boiler can give signals in different combinations and with different intensities. The type of light signal depends on what kind of 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 the suspension, the operation of the boiler is not adjusted, the unit goes into emergency mode;
  • indicator blinking - activation of the limit temperature sensor. Sometimes the error can be eliminated using the mode switch.

Simultaneous blinking of the red and green diodes occurs in the event of a breakdown of the NTC sensor.

The yellow indicator comes on and lights up continuously when the preheating of the coolant in the circuit is turned on.

Repairing a gas boiler Beretta

If you are not confident in your abilities and knowledge, it is strongly recommended to invite a qualified technician to repair the Beretta gas boiler.

To eliminate all of the above-described problems with Beretta gas boilers, it is strongly recommended to use the services of the masters of authorized service centers and organizations with whom contract signed for the maintenance of gas units and the supply of blue fuel.

Independent intervention in the complex design of boilers can lead to even more serious damage, which will result in costly repairs and a long shutdown of the autonomous heating system.

Conclusions and useful video on the topic

To eliminate failures and errors during the operation of the Beretta gas boiler, you must understand the principle of its operation:

The video below will help to recognize the errors of Beretta boilers:

An example of identifying and eliminating a Beretta gas boiler error:

If your Beretta gas boiler began to give out this or that error, it is not recommended to let things go by themselves and delay with repairs or adjustments. But before contacting the gas workers, it would be nice for the owner of the equipment to figure out what the equipment error is.

Knowing the cause of the detected failure will help the owner find the best solution to the problem when communicating with the authorized service master.
