Error codes gas boilers Ariston signaling malfunctions

The popularity of technology under the HotPoint/Ariston brand is associated not only with the slight price of all products. The functionality of this technique is often approached in their characteristics to the flagship models of famous manufacturers.

So, for gas devices of this developer, the presence of such functions is considered the norm:

ariston, boiler, burns
  • Automatic maintenance of water temperature at the output, regardless of any changes in the environment, as well as when the temperature fluctuations in the water itself and its pressure change. Flame intensity is regulated without the participation of the user;
  • Automatic air pumping out of the heating system, which creates safe conditions for the operation of the device;
  • In the event of emergency situations, the operation of circulation pumps is blocked.

All protective systems, as well as the flame for maintaining and regulating flame, works through an electronic fee. This allows you to organize not only a convenient panel with the control buttons, but also the indication of the current operating mode, and, if necessary, errors indicating the alleged cause of the problem that has appeared.

The decoding of these codes is usually presented in the operating instructions. The owner of the technique can independently understand the situation and, as it has skills, also eliminate the cause. But in most cases, such information is useful only in order to determine whether it will be enough just to restart the boiler or it’s time to call the master to the house.

The most frequent errors and ways to eliminate malfunctions

The most popular among Ariston boilers are 24 kW wall models. In the process of work, the gas of the boiler Ariston may occur malfunctions and malfunctions, like any other technique. The list of error codes is given in the instructions in the form of a table. Some of them are a failure in the operation of automation (cause a protective shutdown of the device) and are eliminated by pressing the “reset”, and some signal the malfunctions and interference in the boiler and require intervention (block the system).

All codes are divided into six groups by the number of boiler nodes. The first value indicates the node in which the failure occurred, the rest.Error code.But it should be noted that if a protective error is repeated often, this indicates a malfunction.

  • Error SP 3 (5p3). Refers to problems with ignition and means gearing flame. Removes on Ariston Clas Evo models, talks about problems in the gas unit. Checking and adjusting the gas valve can solve the problem, but in some cases the reason lies in the improper assembly of the coaxial pipe on devices with a closed combustion chamber; Ariston Clas Evo boiler control panel
  • Error 501. Lack of ignition. Check if the gas valve is blocked, if there is a supply, you should pay attention to the electrode of ionization, it can get wet, dry it with a hairdryer. See if he was bent, the distance from the electrode to the comb should be 8mm with a tolerance of 1 mm, whether the electrode connection to the board;
  • Error 607. Fucking the Contacts of the Fan Control Relay, replacing the relay, and sometimes the entire electronic control unit.

Error 101 denotes overheating, the sensor was triggered, after cooling the boiler is launched. The reason may be an accumulation of scale in the heat exchanger, as a result of which the duct decreases and the temperature or interruptions in the operation of the circulation pump increases. Rinse the heat exchanger, adjust or change the pump. Sometimes the reason may lie in increased gas supply, screw the valve, if it does not help, you need to adjust the gas valve.

103,104,105,107

Error 103, error 104, error 105, error 107 occurs when water circulation is violated in the circuit, its absence or low pressure. This happens when the air has accumulated in the system to remove it in Ariston Egis Plus 24 boilers (Ariston Ais Plus 24) click and hold the Mode button for 10 seconds. On boilers Ariston Matis and Ariston Uno, hold the Rezet button no more. Within 5 minutes, the pump without ignition will work, removing air from the system. Then check the pressure, norm 1-1.2 bar, if necessary, increase.

Ariston Egis Plus 24 boiler

Error 108 appears with insufficient water pressure in the heating circuit. Why pressure drops. The cause may be a leak from heating radiators, you should check the joints in the pipes. In the heating season, it will not be easy to notice a small leak, since on hot batteries a small smell will evaporate. You need to turn off the heating and add the pressure up to 2.5 bar to determine the scene of the leakage.

The next reason may be the leakage of heat exchanger pipes. To eliminate, you can steal a heat exchanger, if soldering is impossible, it is required to replace it. The expansion tank may be depressurized or the membrane in the expansion tank has become unusable. Seal the tank or change the membrane.

It can also leak the tank itself. You can determine this by pressing the spool in the upper part of the tank. If at the same time there is a water release, change the tank. How to raise pressure. You can use a home.Made original device consisting of a plastic bottle, crane and spool. On a plastic bottle, cut a thread on the lid with a tap so that you can fix the tap on it.

ariston, boiler, burns

Drill a hole from the back to fix the spool on it. We put the spool into the bottle and fix it. Pour water into the bottle, close the tap and connect the heating system to it through the hose, connect the pump to the spool and, swinging it, pour water into the heating system. The procedure for pumping water into the system is repeated to normalization of pressure, up to 1.5 atm.

Error 109 appears at an excessive pressure above 3 bar and is considered one of the infrequently arising. To eliminate, you need to reset the pressure, as prescribed in the instructions for the device, using the crane of Maevsky. If this does not help, most likely, the reason lies in the secondary heat exchanger.

Когда внутри теплообменника разрушается перегородка, это может быть свищ в ней, начинается смешение жидкостями. Water from water supply, which has higher pressure. Begins to enter the heating system, as a result of which the pressure rises. What to do if it happened.Elimination of the fistula or replacing the heat exchanger will help to solve this problem.

Error 117, according to the instructions for the Ariston BS 24 FF aggregate, means insufficient circulation. To eliminate, press the reset button, in which case the system will check and adjust the difference in temperature at the input and output of 3.5 degrees in 8 seconds.

When a circuit ruptures or a short circuit of the sensor on the supply of hot water supply, an error 201 appears in the circuit of hot water supply. Contacts should be checked, perhaps they were oxidized, or the wire has departed, or the sensor itself is faulty and it will have to be changed.

Error 302 appears on the display in the absence of a circuit between the control board and the display. The cause may be a violation of contacts or their oxidation, in this case, contacts should be connected or cleaned. Control board may also fail. Replacement is required.

Error 303 means a malfunction of the main management fee, the solution to the problem can only be replaced.

Error 304 also appears in the event of a control payment malfunction and appears if more than 15 discharges are made within 15 minutes.

Error 307, error 308 also appears in case of malfunction of the control board, correct the situation will help press the reset button.

Gazlux Economy and Standard errors

To display errors on this boiler model, a special group of indicators is provided (position 5). With normal operation of the boiler, they display the current power level.

See also  How to install the temperature sensor on the boiler

Error E1. The lower indicator flashes red 1 time per second, the first power LED burns on top. The malfunction is caused by a smoke temperature sensor (for an atmospheric boiler) or a pressure drop sensor for a turbocharged boiler. This malfunction may be associated with difficulty (or impossibility) of removing combustion products. Need to check:

Intake and graduation pipelines. They must be free (visual inspection);

The tubes leading to the sensor of the pressure difference should not be deformed or clogged.

How to do. Repair of gas boiler ARISTON. Chimney error.

Error E2. The lower indicator burns red, the second power LED burns on top. Damage to the temperature sensor of the heating system (feeding pipeline). NTC sensors are checked by resistance measurement. In most cases, at room temperature, the resistance of about 10 kOhm and with an increase in temperature decreases. If there are severe deviations when checking, then most likely the sensor is faulty and it must be replaced.

Error E3. The lower indicator burns red, the third power LED burns on top. The same as for the previous error, but for the temperature sensor of the DIS system.

Error E4. The lower indicator burns red, the fourth power LED burns on top. A signal from a safety thermostat installed at the output from the primary heat exchanger. So, for some reason, the temperature of the coolant exceeded 92 degrees. In most cases, overheating is a consequence of poor coolant circulation. Insufficient circulation can be caused:

Malfunction of the circulation pump (it is difficult or absent to the movement of the coolant)

Poor patency in the heat exchanger (scrap or blockage)

Error E6. The lower indicator burns red, the first and fifth power LED burns on top. The control unit does not determine the presence of flame on the burner. To prevent explosive situations, the boiler automation constantly controls the presence of flame through a special electrode (it is also called the ionization electrode). Когда пламя горения присутствует, то плата через электрод регистрирует ток малой величины, если этого не происходит. The boiler turns off by mistake. Why this can happen:

There is no normal gas supply (the reasons can be different: low pressure in the gas line, clogging of the burner cavities, gas filters pollution, gas valve malfunction)

The ignition system is faulty (chain breakdown on control board)

Malfunction of the electrode of ionization (pollution, closing to the case)

Error E7 (EB). The lower indicator burns red, the second and fifth power LED burns on top. Similarly to the previous error.

The lower indicator burns red, power LEDs blink in series. Electronic board records burning after closing a gas valve. This means that either the gas valve does not perform its function (the gas does not completely overlap. There is leakage), or the electronic board of the boiler is faulty.

Error EP. Lower indicators flashed (green and red). Low pressure in the heating system (there is no circulation). In boilers of different years of production, different devices were used to control the coolant. In boilers until 09/2007 of the Economy series and the standard, Hercon sensors were used (the closure of the sensor contacts during the circulation of the coolant with a speed of more than 4 liters per minute). After 09/2007, differential pressure sensors began to be used. In the Premium series boilers, pressure sensors are used to quantify its value and display on the display. The malfunction that arises suggests that either there is a problem with circulation (the pump is faulty, there is an air cork), or the pressure in the heating system is not enough (the feeding is necessary).

The lower green indicator flashes (often. 4 times), the upper ones do not burn. The function of protecting the boiler from freezing works

The lower green indicator flashes (sharply every three seconds), the upper do not burn. There is no request to turn on the burner, the pump output function is active.

Errors are reset either turning on-off the boiler, or the Reset button (wrench). It is forbidden to exclude protective devices from the control circuit (for example, forced circulation of sensors). If after resetting an error the malfunction occurs again, then it is necessary to take measures to eliminate it for the further normal operation of the boiler.

Other breakdowns

In addition to the above, such codes may appear:

  • 608. The system gives out such an error when the fan has earned, but the press start did not work.
  • H45. The last two numbers can change. The reason lies in the NTSC sensor, there is no hot water at the output, the safety valve leaks. If there is no hot water, but the heating system works, most likely the water duct sensor is faulty, it clogged with garbage.

Another reason may be that the turbine blades were very worked out, stuck to the body, this can become an obstacle of rotation, replace the blades or the turbine itself.

The second reason in such a situation may be the NTC sensor, measure the resistance at its contacts to check its performance with a multimeter, if it is unstable, replace the sensor with a new. If the safety valve leaks, the gaskets may have worn out, replace them.

How to determine an error code if there is no display on the device or without a dial, such as on the Ariston BS II 24FF model? This device is equipped with indication lights, thanks to which you can determine the breakdown. So, for example, if the indicator 90 and the crossed out of the water drop are burning, this means that there was overheating and blocking of the boiler. To eliminate it, you need to check the press start and its connection to the board.

What to do if 6p2 lights up on the display

The display light shows a 6p2 or 6p1 error, tells the user about the incorrect ventilation of the room with the unit: either the combustion products are not enough or not allotted enough.

Problems of the heating circuit

How to turn on heating? Typically, errors in the functioning of the heating circuit begin with the number “1”. If Ariston does not warm the batteries, except for the above are also the following designations:

  • 102. The pressure is broken or the sensor is broken (this is a consequence of poor electrical wiring, namely a short circuit; it is solved by the roller of the cable from the device itself to the main board);
  • 110. The temperature sensor has broken;
  • 111. The pressure is too low (see if the water flows and whether the sensor works);
  • 112. On the return, the temperature sensor is incorrectly triggered (you should find the desired spare part to the gas boiler and change it);
  • 116-interruptions in the work of a thermostat of a warm floor (click TA2-crossroads).

SP3, 5P3

If the wall gas boiler Ariston 24 produces one of the indications (error SP3 or 5P3), maybe there is a disorder with the flame. Elimination of the error separation of the flame of the Ariston gas boiler is associated with a cleanliness in the chimney. It is too clogged with dust and soot or incorrectly arranged, so the fire is immediately blown away or the so.Called gear of flame occurs or occurs.

103,104,105,107

Error 103, error 104, error 105, error 107 occurs when water circulation is violated in the circuit, its absence or low pressure. This happens when the air has accumulated in the system to remove it in Ariston Egis Plus 24 boilers (Ariston Egis Plus 24) click and hold the Mode button for 10 seconds. On Ariston Matis and Ariston boilers, keep the Rezet button no more. Within 5 minutes, the pump without ignition will work, removing air from the system. Then check the pressure, norm 1-1.2 bar, if necessary, increase.

Error 108 appears with insufficient water pressure in the heating circuit. Why pressure drops. The cause may be a leak from heating radiators, you should check the joints in the pipes. In the heating season, it will not be easy to notice a small leak, since on hot batteries a small smell will evaporate. You need to turn off the heating and add the pressure up to 2.5 bar to determine the scene of the leakage.

The next reason may be the leakage of heat exchanger pipes. To eliminate, you can steal a heat exchanger, if soldering is impossible, it is required to replace it. The expansion tank may be depressurized or the membrane in the expansion tank has become unusable. Seal the tank or change the membrane.

When a circuit ruptures or a short circuit of the sensor on the supply of hot water supply, an error 201 appears in the circuit of hot water supply. Contacts should be checked, perhaps they were oxidized, or the wire has departed, or the sensor itself is faulty and it will have to be changed.

Error 302 appears on the display in the absence of a circuit between the control board and the display. The cause may be a violation of contacts or their oxidation, in this case, contacts should be connected or cleaned. Control board may also fail. Replacement is required.

Error codes and ways to eliminate them

If an error code appears on the screen of a double.Circuit gas boiler Ariston, it is recommended to restart the equipment to exclude the possibility of a system failure.

To do this, click the “Reset” button. If this does not help, then the system signals a valid error.

Below we will write about errors in the following order:

These errors are suitable for all Ariston models (for example, UNO 24FF, BS24 kW, etc.D.)

  • SP 3 (5p3). For Ariston Class Evo. Flame breaks. Check the operability of the fuel supply valve. Determine the correct installation of the coaxial pipe, clean it from blockage. Perhaps low gas pressure.
  • 501. There is no ignition. Check if the gas supply crane is open. Inspect the ionization sensor. If necessary, clean the contacts and tighten the wiring.
  • 607. Fan relay malfunction. Install a new element.
  • 101. The protection against overheating worked. Adjust the gas supply. Clean filters from garbage. Perhaps the heat exchanger was clogged with a cape, which led to poor heat transfer and a decrease in pressure. Then it is necessary to clean it using special reagents. Diagnose the pump operation, adjust the mode. Check the temperature sensor and control board.
  • 102. The termistor NTC of the heating system has broken down. Check the termistor for a short circuit voltage in the 0-5 volt range leads to this error.
  • 103, 104, 105, 106, 107. Overheating, low coolant pressure or its volume is reduced. Release excess air from the system. Make sure the pressure is in the 1-1.2 bar range. Check the system for the presence of a leak: heat exchanger; expansion tank; Pipes, radiators.
  • 108, 111. The pressure in the heat exchanger decreased. Perhaps air traffic jams appeared in the system. They should be removed using the crane of the Maevsky. Inspect the system for the presence of leaks. Eliminate them.
  • 109. The pressure is very high (more than 3 bar). Check the integrity of the water circuit. Its damage can lead to mixing hot and cold fluid, which is why the pressure increases. In this case, you will have to replace the heat exchanger with a new.
  • 110. Thermoresistor failed. Check if thermoresistor is connected well. Replace the part.
  • 112. Malfunctions in the work of a returner return. Diagnose the sensor and its wiring. Replace the broken part.

Among the lineup Ariston there are rulers whose boilers do not have a liquid crystalline display.

The error is warned by the light indication:

Note! To replace faulty elements, it is recommended to call a service specialist.

Problems with multi.Zone management (error 7)

Ariston brand boilers allow you to divide the house into zones, for each of which a heating mode will be set.

If a problem arises with one of the sections, the system accurately determines the malfunction, so the repair of a particular circuit can be carried out without interference in the rest of the normally working fragments of the heating network.

  • Error 0x. The problem with the temperature sensor of the heat carrier supply in the zone X. It is necessary to check the sensor contacts or replace this part.
  • Error 1x. The same, only with the sensor on the return.
  • Error 2x. Overheating in zone X recorded. First of all, you need to check the work of the thermostat responsible for this site. It can be just in the departed contact or breakdown of the node. If it works correctly, then you need to change the settings.
  • Error 50. An error of the hydraulic scheme. You need to install the correct type of connected hydraulic module (menu parameter 720). If there is no error, then the problem is in the settings of the scheme itself.

Double.Circuit wall.Mounted heating systems

Ariston’s variety of models from the brand, but Ariston’s overview shows that the most popular line is the line of double.Circuit units. It is supposed to be both hot water supply and heating of the premises from one energy source. When installed in apartments or private houses with a total area of ​​up to 100 square meters. M. The following models presented in the table below are most often purchased.

Model The execution of the combustion chamber power, kWt Efficiency, % Hot water performance, l/min Gas consumption, m3/h Mass, kg
BS24FF Closed 24 93.8 13.6 2.71 thirty
Uno24FF Open 26 91.4 13.9 2.04 29

Instructions for double.Circuit gas boilers Ariston are usually purchased along with all elements of the heating system. If you have lost it, it doesn’t matter, a brief instruction is slightly below that will help you perform everyday management operations. It should be noted that, despite the lower gas consumption, the BS24FF model is a more advanced solution from the point of view of its operational capabilities. So, instructions.

  • For the first launch, you must first make sure that there is air access to the room, ventilation is provided.
  • Check water pressure-it should be within 0.6-1.5 bar. Too low pressure requires the contour. For this you need to open the crane from the bottom of the boiler.
  • Often falling pressure indicates that water leakage from the system occurs. This requires a calling the master.
  • Turning on is simple. By pressing the ON/OFF button.
  • There is the possibility of choosing the “Winter” or “Summer” mode. Respectively, heating of the hot water or only hot water.
  • Using the regulation buttons, you can set the coolant temperature from 35 to 82 ° C and hot water. From 36 to 56 ° C.
  • Disconnecting the boiler with the ON/OFF button leads to activation of the anti.Fried mode. If you need to completely turn off the boiler, you need to transfer the outer switch to the OFF position, remove the boiler fork from the outlet and close the gas valve.

Instructions for the gas boiler Ariston BS24FF notes the differences in the types of combustion chambers. It indicates, in particular, that the presence of an open combustion chamber can lead to a lack of oxygen in the room where such an aggregate operates. Therefore, the useful area of ​​the kitchen, where most often products are installed with an open combustion chamber, should be much larger than in the previous case. Otherwise it leads to a malfunction.

The coefficient of useful action is slightly reduced. Basically, this happens due to the fact that boilers with a closed combustion chamber pump up the air necessary for the operation of the fuel device directly from the external atmosphere, heating it along the way, which helps to reduce the gas consumption of a private house with your own hands.

The instructions of wall gas boilers Ariston also notes their compactness and ease of installation. At the same time, the UNO 24FF model is designed for relatively small apartments or houses, while more productive options, for example, from the CLAS series, are more suitable for installation in large mansions.

Tips before repairing the Ariston gas boiler

Before looking for problems in the device or send Ariston’s boiler for repair, try to restart the system and press the “Reset” button. Often it helps to restore the work of equipment. Most often, the occurrence of an error is caused by a voltage jump in the mains.

If the boiler Ariston is not equipped with a display, but at the same time its indicator bulbs flash, this does not always mean that there is a malfunction. This happens when they include the “comfort” mode: the equipment is reconfigured for the necessary parameters.

How to eliminate leaks?

Not any breakdown in gas equipment can be eliminated independently.

Therefore, let’s analyze those problems that can be corrected without calling specialists:

  • Pulling the nuts at the joints. The procedure is performed using a gas key. You need to tighten slowly, neatly, but strong enough. After all manipulations, the work is checked using a napkin. If the leak continues, it may be necessary to replace the drive itself with a new one if the thread is twisted in it.
  • Elimination of condensate on pipes. You need to level the temperature in the room where the boiler is worth. This is possible by connecting a new radiator to the heating system.
  • Reducing the height of the flame-if possible, then the operating range of the boiler should be reduced to 45-50 ℃, and also add more batteries to the system. This will not be eliminated, the water heater will have to be repaired, but in the future this approach will avoid repeated breakdown.

If you have skills in working with gas equipment, you can try to independently disconnect the heat exchanger and check it for the presence of leaks. You need to do this only if the flow goes from the bottom of the boiler, and a lot of water is released. If you do not understand the principles of the boiler, then it is better to call a master who himself eliminates the problem.

So, the sequence of actions, if the problem is in the heat exchanger:

  • Turn off the heating system and wait until the water cools down.
  • Drain all the water. If the recharge system is automatic, it is enough just to turn the crane handle. When the boiler is a single.Circuit and there is a separate expansion tank, water is lowered from the extreme in the radiator system by unscrewing the nut.
  • Disconnect the heat exchanger from the boiler, carefully extract it and inspect it for external damage. You can independently pour water through the input hole and plug the output to understand where the very place of the leak is located.

Further, the situation can be solved in several ways:

Gap and slip of the flame

During the work of burners, two types of combustion instability are possible: a passage of flame in a burner and a breakdown of a flame from a burner.

The flame passing is the movement of the front of the flame from the furnace to the burner, in which the burning of fuel begins directly in the burner. When passing the flame, products of incomplete combustion of fuel are formed into the burner, the burner is hot and may fail.

Flame separation is the movement of the flame front from the outlet of the burner in the direction of the gas.Air mixture, accompanied by extinguishing. Gap leads to filling the firebox with a gas.Air mixture, and then to cotton or explosion. Flame separation can occur with any principle of fuel burning. Sprinking flame in the burner is impossible with the diffusion principle of burning.

Sprinking flame for burners with preliminary mixing occurs if the gas output speed rate is less than the flame distribution rate.

Flame separation from burners of any type occurs when the gas output rate or gas.Air mixture is greater than the flame distribution speed.

The amount of air in the gas.Air mixture is one of the most important factors affecting the speed of flame spread. In mixtures in which the gas exceeds the upper limit of its ignition, the flame does not spread at all. With an increase in the amount of air in the mixture, the speed of flame spread increases, reaching the largest value when air content is about 90% of its theoretical amount of gas necessary for complete combustion.

From this it follows that with an increase in air supply to the burner, a mixture is created, a more poor gas, capable of burning faster and cause a slip of the flame inside the burner. Therefore, with an increase in the load, the gas supply first increases, and why air, and when the load is reduced, on the contrary, the air supply, and then the gas, first decreases. For this reason, at the time of starting the burners, the air should not flow into them and the gas ignition is carried out in diffusion mode due to the air entering the furnace, followed by the transition to the air supply to the burner.

The reasons for separation of the torch from the burner can be a sharp increase in gas or air pressure, violation of the ratio of gas-air, a sharp increase in the vacuum on the exit of the furnace, the operation of the burner outside the passport.

The reasons for passing the flame in the burner may be a decrease in gas or air pressure, a decrease in the performance of burners with preliminary mixing of gas and air below the values ​​specified in the passport.

The actions of the operator of the boiler room when slipping and separation of flame

When passing the flame, it is necessary to adjust the operation of the burner, changing the ratio of gas-air.

When the flame is separated, the boiler is an emergency stop, according to the instructions.
