Arderia boiler error codes

Russia’s Arderia heating equipment was created based on well-liked Bulgarian and South Korean models. In order to reduce the frequency of operational errors in Arderia boilers, the information system has been customized to the specific needs of the area.

Three categories can be used to group the primary mistakes made by Arderia boilers:

1. Information message.
2. Information that requires a user response.
3. Specialist intervention is required.

Nevertheless, even if the Arderia boiler diagnostic system flags it as a minor incident, you should still check any code or error message. Every code that is shown has to have a purpose. Thus, it is imperative to check the gas boiler and determine the underlying cause of the Arderia diagnostic system activation and the code’s display on the screen, at the very least.

A1 error

The fan pressostat has been found to be non-functional by the boiler diagnostic system. The membrane box’s contacts could be shorted, or the condensed water inside the pipe could freeze and form an ice plug, which would be the cause of the code. Avoid knocking on the diaphragm as this will cause damage rather than aid in getting the gas boiler back up and running.

A broken conductor inside the box could be the cause. Typically, in this scenario, the pressostat can be taken out and examined using a multimeter after the Arderia is de-energized (code reset). In the event that the device displays a break, a new or functionally used unit must be found.

Error A2

The code indicates that the system’s air supercharging isn’t working properly. The cause could be fan blade or bearing contamination if the boiler is older. It is advisable to inspect the wiring pads of the starter relay or electric fan on newly acquired equipment.

Small debris that the wind has blown into the inlet could be another source of the code. Owners of gas boilers will occasionally install a "mosquito" cut in the pipe mesh to prevent insects from entering the apartment through the gas boiler. However, in this instance, cleaning of the protection is required at least once every two months. If not, Arderia will consistently produce the "A2" code.

Error A3

Interpreting the code points to a relay pump system malfunction. It is preferable to temporarily swap out the problematic pump for an older, known-to-be-serviceable model if at all possible. The sound test can be used to determine the pump unit’s condition. Replace the pump with a new one if there is a hum, whistling, or jumping revolutions.

However, the gas boiler sensors should be checked for issues if the code fires once more.

Error A4

Extreme code for heating. It’s possible that there are errors and distortions in the way the flow sensor and pump are operating. The Arderia gas valve or the heat exchanger may be impacted in this situation. This is the cause if the boiler screen displays the code A4.

Error A5

The code typically shows up when the water pipe’s head is low. It is necessary to open the kitchen mixer and check the pressure before resetting the message. The tap at the apartment’s or house’s water supply inlet needs to be fully opened if the pressure is extremely low.

Furthermore, even with the gas burner turned on, the DHW should not be turned on when the water pressure is low. The gas boiler system in Arderia may occasionally overheat and block. Although the heat exchanger won’t be harmed, there is a chance that the coupling seal before the heating circuit will leak.

Error A6

The code indicates an issue with the ignition. Low gas pressure is typically to blame for the code. To verify the version, light each burner on the gas stove. The Arderia electronic board or the boiler valve may be the issue if the burners are operating steadily.

Attempting to start the gas boiler at night, when gas consumption is lower and pipe pressure is higher, is an additional option. A blockage in the inlet tap is the issue if Arderia is operating normally but the code is not displayed.

Error A7

Interruption of the burner’s gas fuel supply. The control unit, relay, or gas valve itself could be indicated by the error code. Individual checks can be made by mounting the "suspicious" unit on an operational Arderia boiler. A tester should be used to test the valve and relay.

Error A8

Gas may still be burning inside the combustion chamber after turning off. Occasionally, through pops or a thin flame on an extremely large burner aperture. It is also possible for the combustion sensor’s failure code to show up. The gas valve in the boiler is the source of the issue. An Arderia Center technician must make the diagnosis.

Error A9

The Arderia diagnostic system has detected water temperature below the minimum allowable temperature, which is the reason for the boiler stop code. The boiler pumps water and reads the sensors if the gas equipment is left in an unheated room without power. The diaphragm of the gas valve and sensor cannot operate at 5 o C, and Arderia is blocked with code A9.

Error AA

Typically, anomalies in the Arderia’s autoregulation system—which comprises the control unit, temperature sensor, and gas valve—cause the "boiler boiling" error message to appear. One of these appliances is malfunctioning.

Error AB, AC

After operating for six to seven months, the thermostat will break if the water in the boiler make-up system was poured into the circuit without a filter. In case the code keeps coming up, you must immediately inspect the wiring and contact terminals.

AE error

Uncommon code variation. indicates the formation of a gas "plug" of flue gases and a blockage in the Arderia smoke exhaust system. It might be a bird hiding from the frost in the pipe, icicles, or a snowcap. At the very least, ice and snow must be cleared from the chimney head in order to remove the plug.

Arderia boiler error codes B10, B14, B16

There are plenty more, and the severity of each one justifies ignoring the code that shows up on the screen. As a result, this section needs to be examined in greater detail.

E1

Any gas heating boiler will have this issue. Arderia is not an anomaly either. The decoding indicates that the code indicates an ionization sensor failure. Even at high flame, there is no current flow between the electrodes. It could be an ignition unit failure or dirty gas.

E2

The presence of the error code "E2" on the gas boiler screen indicates that the system does not have a regular air supply to operate the gas burner. In other words, the pressostat on the Arderia is operational, but the supply duct is clogged or the fan is broken.

The Arderia’s heat exchanger will likely burn out due to soot buildup if the cause of the E2 code is not resolved. It will be necessary to replace the heat exchanger with a new one.

E3

The appearance of the code is a result of infractions when using the pump. Generally speaking, the engine revolutions are not altered by the Arderia control system while the gas boiler is operating. If the reduced water flow rate is clearly visible, either the impeller or the control system is having issues.

For a thorough diagnosis of Arderia, it will be essential to contact a master if the code returns after restarting the gas boiler.

E4

Grave issue. The heat exchanger’s temperature has increased, as indicated by the error code. Arderia needs immediate intervention. At the very least, you must open the hot water tap (DHW) at a low flow rate and lower the temperature using the regulator (which is managed by the height of the flame above the gas boiler burner).

You must lower the heat head if you can hear the water in the heat exchanger boiling. Switching the pump to a higher revolution can occasionally be helpful. You can also slightly close the gas pipe tap.

Wait until the temperature returns to normal before turning off the boiler.

E5

The inlet water temperature sensor is typically responsible for the "E5" code’s appearance. It is essential to inspect the terminal contacts and possibly the sensor itself. Oxided contacts are frequently the source of failure in older equipment. Metal needs to be taken out, cleaned, and solvent-wiped. Restart Arderia after that, and observe how the gas boiler functions at various output levels.

E6

Incorrect or non-existent readings from the DHW sensor. When hot water is drawn, the error message might also appear on the screen in addition to the code. The water’s temperature can fluctuate dramatically when you turn on the faucet.

Therefore, turn on the boiler again (reset the code) first, but not before shutting off all of the DHW water extraction taps. After letting the Arderia run in regular heating mode for ten to fifteen minutes, add power and reopen the DHW tap. The sensor has to be changed if the code resurfaces.

E7

Decoding the code indicates a heating circuit inlet issue or a problem with the liquid’s temperature control at the boiler outlet. For this, the "WarmTerm" sensor is to blame. A break in the terminal could be the cause.

Arderia must be turned off in order to inspect the contacts and wire harness leading to the gas boiler’s control unit. Rebooting the Arderia will restore it to its original mode if the code is indicative of a broken contact.

If the error code appears again, it could be coming from the control unit of a hot boiler.

E8

Although the error does not pose a significant threat to the boiler’s functionality, the emergence of the code "E8" warrants careful attention. Despite the absence of a flame beneath the heat exchanger, the Arderia diagnostic system recognizes the existence of a burning front based on sensor readings. This indicates that the ionization sensor has a short circuit, and it needs to be replaced or at the very least scaled down.

E9

The code indicates that the heating circuit’s water pressure sensor has been activated. Either the Arderia control system is malfunctioning, or the sensor has failed entirely. Verify the water pressure in the circuit as a first step. Following the minimum power reduction, this needs to be done right away.

A leaky water supply could cause the heat exchanger to burn out. As a result, as soon as the regulator is turned down to the lowest setting, water must be added using the make-up tap and the pressure must be measured using a hand gauge. It will be essential to locate the leak and examine the sensor’s functionality following the gas boiler’s reset.

It’s essential to comprehend Arderia gas boiler error codes if you want to keep your heating system safe and effective. Through deciphering these error messages, homeowners can identify problems early and avoid expensive malfunctions. We’ve looked at common error codes in this article, along with their meanings and advice on how to diagnose and fix them.

An ignition failure error code is one of the most commonly encountered error codes. There are a few possible causes for this, including problems with the gas supply, malfunctioning igniters, and blocked burner ports. In the event that this error occurs, make sure the gas supply is turned on and leak-free first. Next, check the igniter for any debris or damage that might be preventing it from working properly. Enhancing ignition performance can also involve cleaning the burner ports.

Overheating is another frequent error code that, if left unchecked, can seriously jeopardize public safety. Restrictions in airflow, broken thermostats, or malfunctioning temperature sensors can all lead to overheating. Check the air vents to make sure they’re not obstructed by furniture or other objects if you receive an overheating error. Furthermore, confirm that the thermostat is properly adjusted and operating. It might be essential to replace the temperature sensor if the problem continues.

Another issue with gas boilers is leaks, and you should never disregard error codes that indicate leaks. These codes usually point to an issue with the expansion tank, pressure relief valve, or internal parts of the boiler. It’s critical to turn off the boiler right away and call a qualified technician for an inspection and repairs if you see any leaky signs or receive a related error code.

Finally, by being aware of Arderia gas boiler error codes, you can better maintain your heating system by being proactive. Homeowners may guarantee that their boilers continue to operate efficiently, safely, and dependably by quickly resolving the problems these codes indicate. Never hesitate to ask for professional assistance when necessary, and always refer to your boiler’s manual for specific error code interpretations and troubleshooting procedures.
