DIY Ferroli Diva 24 boiler repair

Today, a gas boiler is a must in every home. Every year, residents of our country have to deal with planned and unscheduled outages of hot water. And private houses and many new buildings, in general, are designed only for individual heating. As a result, sooner or later, many of us have to think about purchasing a boiler or boiler. This article will focus on gas boilers from Ferroli. Let's talk about the types of heaters, their operation and possible breakdowns.

Ferroli is an Italian company that produces various household appliances from heaters to various air conditioners. For the first time she declared herself in the middle of the last century. Over the decades of its work, Ferroli has become an international company with branches all over the world, including Russia. In our country, their products are known for high quality and affordable prices. Heaters are the main layer produced by the engineering firm. Basically, their varieties depend on the power source. Accordingly, they are:

• gas;
• electric;
• solid fuel;
• diesel.

This article will focus on gas boilers. They, in turn, are also divided into subspecies according to their parameters. Let's take a closer look at them.

• Single-circuit - the simplest version of boilers. Aimed exclusively at space heating. They are not able to heat water, which means that in addition you will have to purchase other equipment. But single-circuit boilers have high reliability, which is provided by the internal device. Its main elements include a heat exchanger, expansion tanks and circular pumps.

• Double-circuit - they are solving the issue of purchasing additional equipment for heating water. This equipment is aimed at performing two tasks at once. These heaters are equipped with two heat exchangers. The water that circulates through the heat exchanger serves not only to heat the room, but also to provide hot water supply.

It is worth noting: a double-circuit boiler is in no way superior in size to a single-circuit one. But due to the complex structure, the level of reliability decreases. By the way, there is a bithermal subspecies of double-circuit boilers. Its peculiarity lies in the fact that one heat exchanger is located inside the other. With this structure, boilers become the least reliable.

• Open combustion chamber - heaters that require an inflow of oxygen from the external environment. Therefore, the occupied space must be equipped with ventilation and a chimney. The latter is necessary for the removal of combustion products. Before installing such a boiler, the room will have to be prepared in accordance with all fire safety rules. This type of boilers has a simple structure, high reliability, and low productivity. The models make little noise during operation.

• Closed combustion chamber - such boilers are the least harmful to the environment. They work with a special burner. Among other parts, there is a fan that supplies air. It also removes combustion products, so it doesn't matter if there is draft in the chimney or not. This type of boilers is the most efficient, but less reliable. Often there are problems with the fan. By the way, it makes a lot of noise during operation.

Many of these models are condensing. That is, they differ in low fuel consumption with a fairly high efficiency. Others (convector boilers) lose a lot of heat along with combustion products, which is a serious disadvantage.

• Wall mounted - the most popular type of gas boilers.The demand for them is due to their compact size, affordable price and sufficient performance to heat an apartment or a private house. They are also easy to install due to their low weight. This type usually has a closed combustion chamber.

• Floor - a powerful type of boilers designed to heat large rooms. Their dimensions and weight are far superior to those of wall heaters. The price is also noticeably higher. Such boilers are rarely used in everyday life.

Ferroli products boast a wide selection of various models. You can choose a heater based on any requirement. However, not all of these models can be presented in Russian home appliance stores. Fortunately, today Internet services with a delivery service can always come to the rescue. Consider the most famous and common boilers from the Ferroli company.

• Domina N - one of the new models released in 2013, replacing the old boilers that were discontinued. The unit belongs to the bithermal subspecies, that is, it has two heat exchangers and the second is located inside the first. They are made of copper and coated with a heat-resistant substance that increases their service life. Wall-mounted boilers of this model can have both a closed combustion chamber and an open one. Domina N is distinguished by a long range of advantages, including: pleasant design, small size and weight, electric ignition function, anti-lock pumping system, frost protection, the ability to connect a remote control, high efficiency, safety and reliability.

• Ferroli diva - another modern wall-mounted boiler. It has two heat exchangers to heat the room and supply hot water. Equipped with a simple and accessible control panel with digital display. Like the Domina N model, it has subspecies with different combustion chambers. Among the advantages of Ferroli Diva are elegant appearance, ease of installation and maintenance, electric ignition, efficiency level of 93%, self-diagnosis, safety, plate heat exchanger for hot water, anti-corrosion compound that covers the steel combustion chamber and an electronic board for modulating power.

• Divatop micro - the newest of the models, featuring a number of innovative features. A rather popular boiler today. Boasts increased efficiency and reliability. Consists of two separate heat exchangers made of copper. And three-way inverter valves provide ease of use. The boiler program is able to independently maintain the set temperature for a long time. This model has an innovative self-diagnosis system that ensures maximum operational safety.

The Divatop Micro price may seem overpriced in comparison with analogs, but at the same time the boiler is equipped with a full set of accessories that make it much easier to operate. Other advantages include a fan with adjustable rotation speed, LCD display, automatic weather recognition system, wide functionality and convenient location of internal components.

Breakdowns happen even with the most expensive and reliable equipment. If something is wrong with the gas boiler, you need to calmly figure out what exactly happened.

Perhaps this is not a breakdown, but a small glitch. Ferroli boiler, malfunctions are indicated by three LEDs.

Let's figure it out: what these signals mean, what can be the cause of the Ferolli gas boiler malfunctions, and how the problem is fixed.

While the warranty period has not yet expired, the owner has the right to receive free repair and maintenance. Repair can be refused if the following terms and conditions have been violated:

• ventilation was not organized;
• grounding is not done;
• factory seals are broken;
• there are damages on the case, such as dents and scratches;
• high humidity in the room;
• the boiler room is very dusty;
• power surges in the network;
• main gas of poor quality or with pressure drops;
• the oven was overheated.

In all other cases, you can contact the service department responsible for the Ferroli boilers in your city:

1. Moscow - "Thermo-Prestige".
2. St. Petersburg - Energo Garant.
3. Yekaterinburg (and 80 km around) - Hat House.
4. Novosibirsk - "GUDT TeploVodoMontazh".

The results of self-diagnosis of boiler malfunctions are issued in the form of a code on three LEDs.

In case of some breakdowns, the boiler is blocked. To remove the lock, press and hold the Reset button. Such errors are denoted with the letter "A", they require repair.

1. Is the gas supply normal - the inlet pressure should be 20 bar.
2. What is the pressure of the coolant - the norm is 0.5 - 1.5 bar.
3. Is there electricity.
4. What is the consumption of tap water (4 liters / min is the minimum).

Indicator: Red light flashes quickly.

• Gas does not flow. Check if the air trapped in the pipes is interfering with the gas flow.
• Ignition electrode defective. You need to make sure that the wires are connected correctly, that the electrode is correctly installed and there is no deposits on it.
• The gas valve is broken. If this is the case, it is better to replace the valve.
• If the ignition power is too low, it must be adjusted.

Russian-made gas boilers may well compete with foreign manufacturers in some parameters. For example, their low cost with good performance and reliability. Here https://my.housecope.com/wp-content/uploads/ext/1207/otopitelnoe-oborudovanie/kotly/gazovye-rossijskogo-proizvodstva.html we will analyze the main manufacturers and point out the strengths and weaknesses of domestic products.

Indicator: green light is on or flashing.

The burner is off, but the automation detects the ionisation current and displays an error. If there was a request for ignition, the lamp is on. If there are no requests, it blinks.

• This could be due to the ionisation electrode: It may be dirty. Perhaps the gap between the electrode and the burner is broken (norm - 3 mm). Damage may be on the electrode cable.
• Low ignition power: adjust in parameter menu P01.
• There may be a breakdown in the control board. Restart the boiler. If the error persists, the board needs to be changed.

Indicator: red light flashes quickly.

• The water is not circulating well in the system (normal pressure 1.2 bar). This may be due to a malfunction of the circulation pump, air entering the pipes, or a blockage.
• The circulation pump could fail due to voltage surges if a stabilizer is not installed. Check the resistance at the pump stator.
• If there is damage to the impeller, the pump will run but not supply the correct voltage.
• Also, the pump can be checked for seizure. To do this, unscrew the plug from the front side and turn the shaft several times with a screwdriver.
• If the pump does not receive electricity, the problem is in the control board. You need to change it.
• If the pump is working properly, the air has been released from the system, the pipes have been cleaned, and the boiler is still heating up, replace the temperature sensor.

Indicator: flashes green quickly. The purpose of the flue gas sensor is to shut down the boiler if it overheats.

In this case, the boiler is automatically blocked for 20 minutes.

Just be patient and after unlocking start the boiler again. You may not have to do anything else.

Otherwise, you need to check the chimney:

• is it not contaminated;
• if there is ice and other problems that could lead to a violation of traction;
• is the pipe length sufficient;
• Could the thrust “overturn” occur due to the strong wind?

Indicator: green and yellow lights flash quickly.

It could be a short circuit or a wire break. It is necessary to check the resistance of the sensor, the correct connection of the wires.If you cannot fix the problem, the sensor will have to be replaced.

Indicator: yellow flashing quickly.

Most likely, you just need to add water to the system to the desired level. If the problem is due to a water leak, the leak must be found and repaired.

Indicator: red and yellow flashing alternately.

The boiler will not turn on until the t sensor drops to 45 0 C.

It is possible that the circulation of water is disrupted due to the fact that the pipeline is clogged (or overgrown with scale). Air could have entered the system. If this is not all, look for a breakdown in the sensor itself or the circulation pump (see error A03).

It is triggered when the current falls on the coil or the circuit is open.

The coil must be ringed for a short circuit between turns and an open circuit. Normal resistance is 24 ohms.

After restarting the boiler, check the operation. If the error persists, the problem is in the control board.

In case of such an error, after restarting the boiler will be blocked for 5 minutes (the fan will continue to work).

• It is necessary to check the pipe and the boiler draft interrupter for contamination, for possible turbulence and overturning of the draft due to the wind.
• Check the operation of the fan: if there is any damage, measure the voltage (norm - 220V). Check the connection of the connectors to the fan.
• Check the gas valve: there is no short circuit in the coil, no breaks. Measure the resistance: in the modulating valve it should be 24 ohms. If the valve breaks down, replace it.
• Check the ionization electrode: check the gap between it and the burner (norm - 3 mm), whether the cable is intact, if there is a lot of dirt, clean it.
• Check grounding.
• If everything has already been done, restart the boiler. If the problem persists, change the control board.

As you can see, many errors block the boiler and you just need to wait. However, if you find out that the problem is more serious, call specialists. Error codes for gas boilers are provided for informational purposes only. If you are not an expert in this field, do not try to fix complex breakdowns yourself!

Possible malfunctions, diagnostics and repair of wall-mounted gas heating boilers FERROLI DIVA F24 and DIVA C24

FERROLI gas boilers are reliable equipment of a European manufacturer. Breakdowns, failure, deterioration in the operation of gas boilers DIVA F24 and DIVA C24 FERROLI, like most other heating equipment, are often associated with the following reasons:

• frequent and significant voltage drops in the power grid;
• a large amount of coarse, colloidal impurities in water and the salts it contains;
• incorrect starting and setting of the boiler, refusal from the regular maintenance prescribed by the manufacturer;
• exceeding the established boiler service life.

To avoid breakdowns and malfunctions of the DIVA F24 gas boiler, as well as the DIVA C24 boiler, you should always use a reliable voltage stabilizer and a filter for the water entering the boiler. And also to carry out annual boiler maintenance, in which all boiler systems are checked, which makes it possible to identify many problems before the boiler fails. In addition, cleaning and adjustment is carried out, allowing the boiler to operate stably and last longer.

Below is a list of symptoms and the most likely replacement parts:

Thanks! That's right! Everything will work well now. Like unambiguously.

Stop! Are you sure that the burner ignition settings are on top? Or is it still the hot water heating capacity? It's just that I have the same boiler, the same problem during ignition, a very large flame and the water overheats until the circuit breaker or thermal relay is triggered. I'm going to try now. And in order for me to correct the cause, or rather the problem of high flame, I had to reduce the maximum burner pressure.
