Gas boiler does not turn on - types of problems, poor draft, pressure drop, electronic errors, how to fix

Error SP3 or flame separation on the Ariston Egis Plus boiler

When the boiler goes out, various indicators light up, but most often 60 70 80 + chimney icon. Ariston BS boiler

The Ariston brand offers various versions of gas heating equipment; boilers differ in design features and characteristics. But the reasons that trigger the “flame separation” error are identical for all Ariston models. The article tells you what needs to be done to eliminate it.

Meaning of the malfunction

It is not difficult to determine the algorithm of actions to eliminate the error, understanding what causes it. There are several reasons for the flame to come off, but if we sum them all up, we can distinguish external and internal ones associated with problems in the Ariston boiler itself. Error 5P3 is a consequence of unstable operation of the burner or failures in the electronic circuit.

External factors causing the error: chimney (excessive or insufficient draft, deficiency of oxygen entering the boiler), supply voltage source, gas supply system.

Problematic components of the Ariston : burner, gas fittings, ionization sensor (control electrode), control board.

Where to begin

• Press the reset button (on the front panel of the boiler). Depending on the version, Ariston is designated as R or REZET. In most cases, the flame out error disappears.

• Check voltage. The electronics of some heating system models are phase dependent. If the boiler is connected to the electrical network directly, through a socket, you need to pull out the plug, turn it 1800 and insert it again. When connecting it to the power source with a cable, the wires (cores) L and N should be swapped.

Pull out the plug, turn 180 degrees and plug back into the outlet.

• Make sure that the power supply parameters comply with the values ​​recommended by the manufacturer. For Ariston boilers this is ~230 V: deviation from the nominal value is no more than ±10%.

The risks of errors occurring in a gas boiler (and not just flame retardation) are mitigated by connecting it to a UPS. Advice on installing a separate stabilizer for Ariston is of little use - the device functions only with a continuous power supply. If we are talking about a country property, it is better to purchase a power supply for the boiler. It contains, in addition to the voltage equalization circuit, a charger and a battery group. Even if there are breaks on the power lines or failure of the backup power source, the heating installation will not turn off, and the house will not be left without heat.

• Check the reliability of the grounding. Ariston models often give various errors when the wire is in unreliable contact with the device circuit.

• Carefully inspect the inside of the boiler. According to repair statistics, up to 70% of errors are caused by violations in signal lines and power circuits: wire breaks or short circuits, insulation damage (breakdowns to the housing), unreliable connections (weak or oxidized contacts). Perhaps this is the problem with the flame separation of the Ariston boiler.

Ariston gas boilers: review of popular models

Small boilers for heating using gas are now often used in houses and apartments, and many of the best such devices are produced under the Italian brand Ariston. We will look at some models of this brand and provide instructions for the Ariston gas boiler regarding these models.

1. Specifically for two models
2. Bs 24 FF
3. Uno 24 MFFI
4. Pivot table

This brand is known all over the world. Its roots, like many other great brands, come from the early 20th century, when enterprising Italians started a family business. Nowadays, Ariston household appliances do not need any recommendations.

Ariston gas boilers, if you do a brief review, reveal themselves to be very reliable and popular. The company mainly specializes in wall-mounted domestic boilers with two heated circuits - for heating and for hot water supply. They are presented in several series:

• Genus;
• Clas;
• Egis;
• Bs;
• Uno.

The first family has rich functionality. The second family is famous for its practicality. The third series is distinguished by the compactness of the boilers coupled with their excellent design. We'll talk about the models of the last two series below. Every type of Ariston gas boiler has good reviews from consumers everywhere.

Specifically for two models

For clarity, let us analyze two specific Ariston models in order to understand what the features and characteristic malfunctions of Ariston gas boilers are. These two models are listed below.

If the first unit is distinguished by its multifunctionality and excellent automation of protection against various changes, then the second one is somewhat simpler, but cheaper.

So, let's get down to reviewing these two very popular wall-mounted double-circuit gas boilers and their instructions.

Bs 24 FF

This is a wall mounted equipment. The unit is dual-circuit, that is, it also heats hot water. Designed for heating a room up to 250 m2. Its power is 24.2 kW, which is quite enough for a comfortable bath.

The main advantages of this model - there are many of them - are listed below.

1. Configured to operate at reduced gas pressure, as well as when the tap water supply is reduced.
2. Has protection against voltage surges.
3. Has pump blocking and frost protection functions.
4. There are adjustments for heating intensity and DHW temperature.
5. There are two built-in water filters - on the first and second circuit.
6. The device's automation is equipped with a self-diagnosis system.
7. The primary heat exchanger (for heating) is copper with a special coating.

How to find the cause of the error

You need to start by testing external systems and devices: breakdowns in Ariston boilers are a rare occurrence.

Chimney

It is not difficult to check the draft: if it is excessive, flame separation is observed; if it is insufficient, a so-called breakthrough occurs, accompanied by a characteristic pop. Incomplete blockage of the tract (clogging) can be easily eliminated using available means.

If a coaxial chimney is installed, you need to inspect the outer part of the duct. Freezing in winter blocks the air supply channel to the boiler. Its lack affects the quality of the combustible mixture, the operation of the burner is disrupted, hence the Ariston flame separation error.

Recommendations

• Models with an open chamber should ensure a sufficient flow of oxygen into the room. If flame separation is eliminated by completely opening doors and windows, you will have to install a forced air supply system.
• The appearance of an error during the initial start-up of the Ariston boiler indicates miscalculations made during the design and installation of the smoke exhaust duct. Here you cannot do without consulting a professional. Possible problems: incorrectly selected path length and height of the first bend (for models with an open chamber), small pipe cross-section, unnecessary turns.

Gas main

Error 5P3 of the Ariston boiler appears when the pressure value does not correspond to the standard value. The optimal ratio of gas and air in the combustible mixture is violated, which leads to flame separation or breakthrough. There are several reasons that initiate a problem with pressure in the pipe.

• Significant temperature fluctuations , non-compliance of the characteristics of “blue fuel” with the requirements of the boiler manufacturer Ariston.
• Glaciation on the highway. Typical for facilities with an autonomous gas supply system. As a rule, the problem is in the gearbox, the operation of which is blocked by the formed ice. But simply warming it up is not enough - you need to additionally insulate the head of the gas tank or an outdoor cabinet with a cylinder group. Otherwise, the Ariston boiler error “flame separation” will appear regularly.

Burner

One of the reasons for flame separation is its instability, caused by the low intensity of the gas entering the chamber from the nozzles. Over time, they become clogged with particles of soot and dust. It is enough to clean the burner, and the Ariston boiler flame failure error will disappear from the display. The work is being carried out in stages.

Burner clogged with dirt and dust

• Heat exchanger maintenance. It is located above the burner, and gradually microscopic fractions stick to the body of the device (in the lower part), rising along with the flame. The technique is simple: the burner is covered with a sheet, film or piece of dense fabric to prevent dirt and dust from getting on the nozzles. Next, mechanical treatment of the ribbed surface of the heat exchange device with a stiff brush (a toothbrush will do). Everything that falls down onto the laid material is disposed of.
• Boiler burner maintenance. Its injectors also require regular cleaning. You will need a vacuum cleaner and the same toothbrush.

Ionization sensor

From it, a signal about the presence of a flame is sent to the control board, which confirms the correct functioning of the Ariston boiler; if not present, the work is blocked. In some models, the sensor and control electrode are separated, but the meaning of the flame failure error does not change.

What to do

• Clean the electrode. All layers are carefully removed with “velvet” sandpaper: burnt dust, soot.
• Make sure the electrode is in the correct position. The wire cannot be bent - it is fragile, only the holder bar.

Ariston boiler ionization sensor

If the measures taken to restore the functionality of the Ariston boiler do not give a positive result, the ionization sensor is changed.

There are other reasons for the flame-out error of an Ariston boiler, but you shouldn’t deal with them yourself - only a professional approach. And no matter what numerous advisers claim, you need to understand the difficulties that you will have to face.

Gas valve

In the instructions for individual models of Ariston boilers, there are recommendations for its adjustment: but this is for professionals. When setting up the unit, you need a special device - a differential pressure gauge. Therefore, all independent attempts are doomed to failure in advance. Perhaps the flame separation error will disappear, but side effects will arise: malfunctions in the operation of the boiler when the mode changes, increased consumption of “blue fuel” and a number of others.

Electronic board.

At home, even a professional will not undertake to test it, much less carry out repairs - you need the appropriate equipment and tools.

Malfunctions of Ariston gas boilers and instructions for eliminating them

The Italian brand Ariston, which hides the world famous manufacturer of household appliances Indesit Company, has been designing and producing gas heating boilers since the mid-70s of the last century. A structural division of Indesit Company is Ariston Thermo Group, whose gas boilers have gained popularity due to the intensive individual construction of residential buildings, as well as the unsatisfactory operation of centralized heating systems in apartment buildings.

In this review, we will look at some of the models of this brand, as well as their technical capabilities. The operating instructions will be attached below.

Double-circuit wall heating systems

The variety of models from the Ariston brand is quite large, but a review of Ariston gas boilers shows that the most popular is the line of dual-circuit units. It involves both hot water supply and space heating from one energy source. When installed in apartments or private houses with a total area of ​​up to 100 sq. m. the following models are most often purchased, presented in the table below.

Instructions for Ariston double-circuit gas boilers are usually purchased along with all elements of the heating system. If you have lost it, no problem; below are brief instructions that will help you perform daily management operations. It should be noted that, despite lower gas consumption, the BS24FF model is a more advanced solution precisely in terms of its operational capabilities. So, instructions.

1. For the first start, you must first make sure that there is air access to the room and ventilation is provided.
2. Check the water pressure - it should be between 0.6-1.5 bar. If the pressure is too low, the circuit needs to be topped up - to do this, open the tap at the bottom of the boiler.
3. Often falling pressure indicates that water is leaking from the system. This requires calling a specialist.
4. Switching on is done simply by pressing the on/off button.
5. It is possible to select the “Winter” or “Summer” mode - respectively, heating + DHW or only DHW.
6. Using the control buttons, you can set the temperature of the coolant from 35 to 82°C and hot water - from 36 to 56°C.
7. Turning off the boiler with the on/off button activates the antifreeze mode. If you need to completely turn off the boiler, you need to turn the external switch to the off position, remove the boiler plug from the socket and close the gas tap.

Conclusion:

Taking into account the cost of the Ariston boiler, it is not advisable to take excessive initiative in identifying and eliminating the flame separation error on your own. Everything that is recommended for the user to check and perform is indicated in the article. There is no result - call a representative of the service organization.

Practical advice

• A one-time visit from a technician due to a problem with the boiler is expensive. On thematic forums you can find the following data: 5000 rubles for eliminating the flame separation error. It is more expedient to conclude an annual maintenance agreement with a service center (cost about 2500). The benefit is double – significant money savings and professional service.

• Experts recommend mitigating the risk of electrical interference on the gas main. For this reason, the control circuit of Ariston boilers often gives failures and errors. In some cases, the program is broken, and the board has to be reflashed. This problem can be avoided by installing dielectric inserts on the pipe (in several places); with professional installation this is done immediately.

• When connecting an Ariston boiler to a gas tank, you need to choose the right supplier of “blue fuel” and conclude an agreement with him. If the flame separation error is caused by low quality LPG, there will be someone to file a formal claim and compensate for possible damage (both moral and material). And one-time calls to fill the reservoir of representatives of little-known organizations, even those offering a low price, should not be practiced. Solving possible problems with the operation of the Ariston boiler will ultimately cost more.

Insufficient gas pressure

Despite the apparent obviousness, quite often problems are associated with the lack of normal gas pressure at the inlet to the boiler. This can be caused either by problems with the gas transportation network itself (which is quite rare) or by internal reasons:

• The gas meter is faulty. Sometimes the meter jams and it stops passing gas in the required volume. To check, you need to see if the counting mechanism is working - its readings should change. Often a faulty meter makes noise or makes other suspicious sounds;
• Problems with leakage or temperature sensors. Gas services usually require the installation of special equipment at the entrance to the boiler, which monitors the level of gas concentration and temperature near the heating unit. When such sensors are triggered or malfunction, the boiler immediately turns off;
• Loss of tightness of connections. Gas leaks can cause a drop in its pressure, which causes the automation system to be activated and the gas boiler to go out. Typically, this situation is easily diagnosed by a noticeable specific odor.

To diagnose and troubleshoot the problem, you need to check all joints with a sponge and soap suds - bubbles will appear at the leak points.

Power outages

It happens that the voltage in the electrical network drops below the permissible level. In this case, the boiler immediately goes out, since modern automation can detect low voltage. When the power supply is restored, the same automation will turn on the burner, so most of these failures can go unnoticed. However, this mode of operation is harmful to electronics, so they may fail over time. So if suddenly the gas does not light up when voltage appears in the network, something may have happened to the automation. To avoid such a scenario, it is better to buy a voltage stabilizer.
