Features of boilers Ariston
Ariston gas boilers are most in demand on the market, thanks to their time-tested reputation. They are distinguished by their compact size, convenient connection and maintenance system, reliable operation, and a variety of models. The company produces single-circuit and double-circuit units, wall and floor, with an open (requires a chimney) and a closed combustion chamber (removal of combustion products through a coaxial pipe).
Ariston devices are equipped with an improved heat exchanger design, which allows to reduce gas consumption, protective automation, due to which the operational life is increased, and precise settings. In case of interruptions in the supply of water or gas, an automatic blocking occurs, which excludes the failure of the device.
Most common error codes and troubleshooting methods
You can find out complete information on the selection, operation and maintenance of gas boilers of all manufacturers if you go.
The most popular among Ariston boilers are 24 kW wall models. During the operation of the gas boiler Ariston, malfunctions and malfunctions may occur, 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 malfunction in the operation of the automatics (cause a protective shutdown of the device) and are eliminated by pressing "Reset", and some signal faults and interference in the operation of the boiler and require intervention (block the operation of the system).
All codes are divided into six groups according to the number of boiler units. The first value denotes the node in which the failure occurred, the rest - the error code, but it should be noted that if the security error is repeated frequently, this indicates a malfunction.
The most common ones are:
101
Error 101 means overheating, a sensor has been triggered, after cooling down, the boiler starts up. The reason may be the accumulation of scale in the heat exchanger, as a result of which the flow decreases and the temperature increases, or interruptions in the operation of the circulation pump. Flush the heat exchanger, adjust or change the pump. Sometimes the reason may lie in the increased gas supply, screw on 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 occur when there is a violation of the circulation of water in the circuit, its absence or low pressure. This happens when air has accumulated in the system, to remove it in the Ariston Egis Plus 24 boilers, press and hold the mode button for 10 seconds. On boilers Ariston Mathis and Ariston UNO, hold the rezet button for no more than 6 seconds. The pump will run for 5 minutes without igniting, removing air from the system. then check the pressure, the norm is 1-1.2 bar, if necessary, increase.

108
By the way! Did you know that a heating boiler from any manufacturer can explode at any moment - "".
Error 108 appears when there is insufficient water pressure in the heating circuit. Why the pressure drops - the cause may be a leak from the heating radiators, you should check the joints in the pipes. During the heating season, it will not be easy to notice a small leak, since a small leak will evaporate on hot batteries. It is necessary to turn off the heating and add pressure up to 2.5 bar to determine the place of the leak.
The next reason may be the leakage of the heat exchanger pipes. To eliminate it, you can solder the heat exchanger, if soldering is not possible, it needs to be replaced. The expansion tank may depressurize or the membrane in the expansion tank has become unusable - seal the tank or change the membrane.
The tank itself may leak - you can determine this by pressing the spool in the upper part of the tank. If this causes water to spill out, change the tank. How to raise the pressure - you can use a homemade original device consisting of a plastic bottle, a tap and a spool. On a plastic bottle, on a lid, cut a thread with a tap so that you can fix a tap on it.
Drill a hole on the back to secure the spool to it. We put the spool inside the bottle and fix it. We fill the bottle with water, close the tap and connect the heating system to it through a hose, connect the pump to the spool and, by pumping it, pour water into the heating system. The procedure for pumping water into the system is repeated until the pressure is normalized, up to 1.5 atm.
109
But it often happens that if our advice and other recommendations are not followed, other often more expensive breakdowns may appear, which in some cases can lead to really dangerous emergency situations. Therefore, to prevent them, we recommend that you arm yourself with additional information.
Error 109 appears when the overpressure is above 3 bar and is considered one of the infrequent. To eliminate it, you need to relieve the pressure, as prescribed in the instructions for the device, using the Mayevsky crane. if this does not help, most likely the cause lies in the secondary heat exchanger.
When a partition collapses inside the heat exchanger, it can be a fistula in it, mixing with liquids begins. Water from the mains, which has a higher pressure, begins to flow into the heating system, as a result of which the pressure rises. What to do if this happened - removing the fistula or replacing the heat exchanger will help solve this problem.
117
Error 117, according to the instructions for the Ariston BS 24 FF unit, means insufficient circulation. To eliminate it, press the reset button, in this case the system will check and adjust the temperature difference at the inlet and outlet of 3.5 degrees in 8 seconds.

201
If the circuit is broken or the sensor is short-circuited on the supply to the hot water supply circuit, error 201 appears.Check the contacts, they may have oxidized, or the wire has come off, or the sensor itself is faulty and it will have to be changed.
302
Error 302 appears on the display when there is no circuit between the control board and the display. The reason may be a violation of the contacts or their oxidation, in which case the contacts should be connected or cleaned. The control board may also fail - replacement is required.
303
In addition, our expert Alexander recommends that you study this problem that occurs with boilers of other firms, models and manufacturers, because when people use them, as a rule, various non-standard situations arise that may coincide with yours. You can do this on our, another site -.
Error 303 means a malfunction of the main control board, the solution to the problem can only be its replacement.
304
Error 304 also appears in the event of a malfunction of the control board and appears if more than 15 resets are performed within 15 minutes.

307,308
Error 307, error 308 also appears in the event of a malfunction of the control board, pressing the reset button will help to correct the situation.
501
The 501 code is described above in the section on most common errors.
601
On models Ariston Egis Plus 24 (Ariston Egis Plus 24) CF, class 24 FF and others, with an open combustion chamber, error 601 means no thrust. The sensor blocks the operation of the column in case of interference in the smoke exhaust system.
This blocking is temporary, after 12 minutes the system will switch to operating mode if the cause is eliminated, otherwise it will repeat again. To eliminate, clean the chimney, if the chimney is free, check the serviceability of the draft sensor.
604
Error 604 occurs when the fan speed is low or the Hall sensor is malfunctioning. The fan and sensor should be checked; if a breakdown is found, replacement is required.

607
The description of the cause of the occurrence and the remedy are described above, in the most frequently repeated errors.
a01
Error a01 blocks the operation of the boiler due to a failure of automatic ignition. It can occur at low unstable voltage in the network, install a stabilizer. The polarity can also affect, in some cases the problem can be eliminated by changing the polarity in the outlet, turn the plug over, changing the phase to zero.
In addition, there may be problems with the flame ionization sensor.Check if it is clogged, not bent, the wire connecting the sensor to the board may be broken or oxidized. Solder or strip the wire.
e34
Error e34 means a failure in the operation of the pneumatic relay when the fan is running. What to do - Check the relay and replace if necessary.
e108
Error e108 means a drop in pressure in the heating circuit. The cause and solution of the problem is described above in the description of code 108.
sp2
The sp2 (5p2) error means that the second ignition attempt is unsuccessful. If the boiler does not start, there may be several reasons - there may be a problem in the ionization sensor, low gas pressure, insufficient air flow, removal of combustion products. Check the operation of the sensor, the gas valve may be closed or not open enough, open the window and the door, check if the chimney is clogged.

sp3 (5p3)
This DTC is described in frequently repeated errors.
1p1,1p2 (ip2)
Error 1p1, 1p2 (ip2) appears in case of poor water circulation or lack of it. Causes and solutions to the problem are similar to code 108 and described above.
6p1
Error 6p1 appears when there are problems with the air supply and smoke removal, the relay is delayed. to eliminate the problem, check if there is enough air in the room where the boiler is installed, if the chimney is clogged, if the relay contacts are stuck.
6p2
Error 6p2 also occurs in case of problems with smoke exhaust and air intake, while the contacts of the pressure switch of combustion products open during normal operation of the fan. The solution to the problem is the same as when the 6p1 code appears.

Other breakdowns
You can find out the whole truth about the conspiracy associated with the choice, operation and maintenance of heating boilers of all manufacturers and models.
In addition to those described above, the following codes may appear:
- 608 - the system generates such an error when the fan started up, but the pressure switch did not work.
- Н45 - the last two digits are subject to change. The reason lies in the NTSc sensor, there is no hot water at the outlet, the safety valve is leaking. If there is no hot water, but the heating system is working, most likely the water flow sensor is faulty, clogged with debris.
Another reason may be that the blades of the impeller have worked hard, stuck to the body, this can interfere with rotation, replace the blades or the impeller itself.
The second reason in this situation may be the NTC sensor, to check its performance, measure the resistance at its contacts with a multimeter, if it is unstable, replace the sensor with a new one. If the safety valve leaks, the gaskets may be worn out, replace them.
NTC sensor
How to determine the error code if the device does not have a display or without a dial, such as on the Ariston BS II 24FF model? Such a 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 water drop icon are on, this means that the boiler has overheated and blocked. To eliminate it, you need to check the pressure switch and its connection to the board.
If you want to get complete information on this problem, as well as find out other important nuances on the heating boiler from your manufacturer,.
But, we also have on this problem and not only, which in the first place you will not find anywhere, because it is asked by specific people who could not get more support and advice anywhere (which they themselves tell us about). And secondly, their problems are so complex that sometimes our expert Alexander Kholodov deals with people for 10 or more days.
And now EVERY question from the user and the answer to it, in order to avoid money costs as a result of improper operation or repair of the boiler. And here it doesn't matter which manufacturer's apparatus is involved in the issue. The only important thing is that unique situation, as a result of which this issue arose, because as one good saying goes: "if forewarned, then forearmed."
