Reliable and stable Beretta gas boiler: faults and their elimination, operating instructions for floor-standing and wall-mounted models

Gas boilers, which provide a source of thermal energy for an autonomous heating system, are the most convenient and efficient option.

They are capable of operating automatically, do not require constant human intervention, are economical and efficient.

A striking representative of the group of gas heating boilers are the Italian Beretta units, which demonstrate excellent performance combined with affordable prices.

Beretta boilers are reliable and stable in operation, and are constantly monitored by their own self-monitoring system for the condition of parts and components.

Let's look at the most common malfunctions of these units and ways to solve the problems that arise in connection with them.

Basic malfunctions of Beretta gas boilers

The design of Beretta boilers is a reliable and durable engineering solution that takes into account all loads and impacts on the parts and components of the unit.

The most likely malfunctions occur in the most critical components that experience maximum temperature or dynamic loads.

According to experts, the most common malfunctions include:

• Lack of flame on the burner, causing the boiler to block. This problem occurs most often, as it can be caused by various reasons, from clogging of the burner nozzles to stopping the gas supply in the mains.
• Failure of the control board - burnout of parts or failure due to condensation. This is one of the most unpleasant problems for the user, since replacing the control board is a very expensive procedure.
• Boiler shutdown due to exceeding the permissible flue gas pressure. Here, the reasons may be either clogging with soot or the appearance of ice at the outlet of the chimney, or increased wind, creating excessive pressure in the chimney.
• Failure of any self-diagnosis sensor. The boiler control system perceives such situations as the occurrence of an equivalent error and immediately takes appropriate measures.
• Low water pressure in the heating circuit supply pipe. If replenishment does not help solve the problem, then there may be a leak or failure of the expansion tank.

IMPORTANT!

The problems listed are among the most common, but this does not mean that they are mandatory - during operation, any accidents are possible, and the described situations may not manifest themselves at all.

Some numbers

Let's talk a little about the technical characteristics of the Beretta Ciao 24 CSI boiler. The rated power of the model is 23.9 kW with a minimum heating power of 7.5 kW. The efficiency of the unit is 91%, which indicates the structural perfection of the boiler. The equipment is capable of efficiently heating the coolant to a maximum temperature of 90 degrees Celsius. The 7-liter expansion tank ensures stable, safe circulation of hot water throughout the circuit.

Compact dimensions and low weight (only 28 kg) mean that the unit can be easily installed even in limited spaces. You can do this either independently or with the help of third-party specialists. At the same time, during the installation of the Beretta Ciao boiler, the instructions are an important assistant, as they describe all the intricacies of installing the unit.

The engineers of the Italian company do not recommend installation if you do not have a sufficient level of technical knowledge. However, even with complete confidence in your own skills, you should not forget about the manual “Beretta Ciao Boiler: Instructions”, which will help you avoid typical problems associated with the installation of gas burner equipment.

How to run self-diagnosis

The self-diagnosis system is a network of sensors located on all important and critical parts and components of the boiler.

They do not need to be started, since they operate in continuous mode, from the moment they are turned on until the unit stops operating.

Therefore, launching self-diagnosis of a gas boiler as a separate function is impossible . Moreover, if it occurs to someone to stop the operation of the system, then no result will be obtained - it is impossible to stop the process using standard methods, and turning off the sensors is regarded by the control board as the same error, causing the boiler to block.

The self-diagnosis system is an integral part of the gas boiler operation process, ensuring the safety of the equipment and notifying the owner or repairman about the location of the defective unit.

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.

Error codes and their interpretation

Let's look at the main error codes (pictures) of Beretta boilers:

NOTE!

Errors of type “A” require a restart of the boiler, and errors of group “E” disappear after the cause is eliminated without the need for a restart.

Popular breakdowns and their elimination

The lower the serial number of the error, the more often it occurs when operating the Beretta boiler.

Let's look at the most common errors and possible ways to eliminate them:

• A01. Blockage due to lack of flame. There are several possible reasons - problems with the gas supply in the main line, the gas supply valve to the boiler is closed, the burner nozzles are severely clogged. Find out if there is gas in the line, clean the burner and nozzles.
• A02. Overheating of the heat exchanger indicates a lack of water. Check the operation of the circulation pump and the coolant pressure, add fluid to the system.
• A03. High pressure in the chimney indicates blockage of the outlet with ice, frost, and soot accumulation. Possible weather conditions - strong gusty winds.
• A 04. A drop in coolant pressure may be caused by a lack of liquid. Check the system for leaks and repair if found.
• A05. Problems with the DHW line thermistor can be eliminated by replacing the sensor.
• A06. A failed heating circuit thermistor must be replaced immediately.
• E33. It is necessary to swap the electrodes in the power plug. Beretta boilers are phase-dependent and do not work if the phase wire is incorrectly connected.
• E46. Exceeding the permissible temperature of the coolant indicates problems in the circulation of the liquid. You should check the operating mode of the circulation pump.
• The bell symbol (bell, p) is flashing. This is a signal from the chimney pressure sensor, indicating that there is an obstacle to the exit of smoke, or the formation of ice or frost at the pipe outlet.

IMPORTANT!

The Beretta boiler error is reset by pressing the shutdown button and turning the boiler back on after 5-6 seconds.

Have you been facing problems with central heating or hot water supply for a long time? These issues can be solved by installing a gas boiler.

User manual

Beretta boilers are operated automatically, which does not require constant human intervention.

The user is only required to adjust the heating mode according to his own feelings, switch the boiler to winter or summer mode (turning off or starting the heating circuit), maintaining the cleanliness of the body and periodic maintenance (by service workers).

All serious problems can only be solved by calling a specialist - eliminating constantly occurring errors or incomprehensible phenomena that occur with the boiler in operating mode.

In addition, the user independently fills the system with water (or recharges as necessary).

The process consists of supplying liquid through the make-up tap and filling the system until the water pressure reaches 1-1.5 Bar. This is below the operating pressure, but when heated, the water will expand and due to the increase in volume, the pressure will reach the desired value.

Here are the main problems that you may encounter when operating the described boiler equipment.

Source

Does not start (does not ignite) - reasons and solution

A boiler failure during startup can be caused by various reasons, which can be determined either by the corresponding error code or by independently checking the condition of the boiler. The simplest option is the lack of gas in the main line.

This problem is external and can only be solved by contacting the gas service . The gas supply valve on the unit itself may be closed. There is another reason for ignition failure - reverse polarity of the power wires. It is displayed on the display as code E33.

The solution to the problem is to reconnect the wires . This situation can arise even after some period of normal operation of the boiler, if any work was done on the power supply panel and the phase and neutral were mistakenly swapped.

If you cannot find the reason for the failure to ignite the boiler, you should contact a service workshop.

Installation features

The user needs to be aware of the main requirements for installing the device:

• It is prohibited to place the device in a living room.
• In the utility room the boiler is placed in any convenient place. In the kitchen, the device should not be mounted above the dining table or above the stove.
• The distance specified in the instructions is maintained between the wall, surrounding objects and the device.
• The body and chimney become very hot during operation. If the device is placed near a heat-sensitive surface, this area must be insulated.
• Before entering the boiler, a shut-off valve must be installed on the gas pipeline. This device is not included in the package. If the water quality is poor, it is recommended to install a filter.

Upon completion of work, it is necessary to check the tightness of all connections. After this, they begin to check the equipment.

How to check sensors

All Beretta boiler sensors are part of the self-diagnosis system. They not only perform control functions, but are themselves objects of observation.

This means that if any sensor fails, short circuits or breaks the wires, the corresponding error code will immediately appear on the display of the boiler control panel. The system polls sensors automatically at the moment of switching on; no special actions are required from the user .

Most of them are thermistors that respond to changes in temperature conditions or when indicators exceed the limits established by the operating mode. The design of the elements is simple; replacement, if necessary, is not difficult and does not take much time.

It is not recommended to change any elements of the boiler yourself; you must call a technician from the service center.

The pump does not work - what to do?

If a failure of the circulation pump is noticed, it is necessary to stop the system and call a technician.

There can be several reasons for failure, from power problems to mechanical problems . The first reason is determined by testing and checking the condition of the pump motor.

The second reason can be detected by checking the condition of the moving parts of the pump, the absence of difficulties in rotating or moving parts of the mechanism, breakage or wear of gears and other elements.

The decision to repair or replace the pump is made based on the results of an examination of the performance and condition of the unit parts . If the forecast for repair work is favorable, the pump is restored, otherwise a complete replacement is necessary.

How to clean the heat exchanger

Beretta boilers are equipped with either separate or bithermal (combined) heat exchangers. In the first case, flushing gives a greater effect; the second type of heat exchangers is difficult to flush due to the design features.

There are two washing methods:

• Mechanical . Requires disconnecting the heat exchanger from the boiler. The results of such washing are not particularly successful, since it is extremely difficult to clean the internal surfaces mechanically.
• Chemical . Does not require dismantling the heat exchanger, but is done using a special device. It has a fairly high efficiency, is able to eliminate scale and extend the service life of the unit.

For washing, special reagents are used to dissolve scale and remove it from the internal cavity of the heat exchanger tubes. The procedure should be performed every 2-3 years, depending on the quality of the water. To carry out the work, you must invite a specialist from the service center .
