Do you use gas equipment Ferroli? Then our article will come in handy. Here are considered all the possible malfunctions and errors of the Ferrol boiler. Whatever problem arises - the equipment does not turn on, the pressure drops, there is no hot water - the recommendations in the table will help to find a way out.
The device and features of boilers "Ferroli"
Ferroli brand gas boilers can be installed in any home, even if the main line is not connected. The equipment is connected to a common pipeline or a separate cylinder with liquefied gas.
Modulation of the flame allows you to evenly heat the heat exchanger. It is made of copper, so the efficiency is 92%. Corrosion-resistant coating extends the life of the device. The ignition unit is also coated with aluminum.
Among the users, the most popular dual-circuit models are Domina, Diva, Domiproject, Pegasus.
Error and Fault Codes
Errors can be displayed on the boiler display or on the control panel. Codes are divided into several categories:
- Critical - "A". When they occur, the system is completely blocked, the equipment does not start. To eliminate it, it is required to exclude the reason for the appearance of characters on the screen, to restart using the “Reset” key. Reboot will not happen immediately, but after 30 seconds after pressing the button;
- Non-critical - "F". Minor problems that require user intervention and system tuning;
- Pauses - “D”. These symbols indicate the intervals between certain modes.
Malfunction code | Value | Solutions |
A01 (In the Domina models, the red indicator flashes). | The burner does not work. No ignition. |
|
A02 (The green indicator lights up when trying to light up. In other cases, it blinks). | The system reports the presence of flame in its actual absence. |
|
A3 (Red light blinks). | Overheat protection tripped. Temperature from 105 degrees. The technique is turned off. | An error appears if the temperature has not returned to normal within 10-50 seconds. Restart the boiler, let it cool. If after that the device does not turn on, then you need to:
|
A06 | Unstable flame. For 10 minutes, the fire went out 6 times. |
|
A09 | Faulty gas supply valve. | Repair or replacement. |
A16 | When closed, the valve allows fuel to flow through. | |
A21 | Burning problems. | Rebooting the system. |
A34 | Voltage drops in the network. | Install the stabilizer. |
A41 | No fever. | Connection of a working coolant temperature sensor. Measure the resistance of the semiconductor sensor with a multimeter. In working condition, it will show 10 kOhm at 25 ° C. Pull the sensor connectors to the control board. Do the same with the hot water temperature sensor (DHW). |
A51 | The chimney, air duct clogged. | Check for traction. Bring the lit match to the control window. If there is traction, the flame will deviate to the side. If it is steady, clean the chimney. |
F04 (green indicator flashes). | The smoke exhaust controller has tripped. | How to turn on the boiler? Restart. Clean the chimney shaft. Stripping contacts or replacing the sensor. Reconfiguration of the electronic module. |
F05 | Incorrectly connected fan (for Ferroli Domiproject DF). | Inspection of fan wiring, voltage measurement. Norm - 220V. Contact Lift |
F08 | Heat exchanger temperature exceeds 99 degrees. In this case, the device operates. | As soon as the temperature is restored to 90 degrees, the code will disappear. |
F10 / F14 | Shorted or cut off the wiring of the thermistor. | Repair wiring or replace a defective item. |
F11 | The DHW thermistor has closed, the contacts are broken. The burner does not light in DHW mode. | |
F20 | Flame problems (for Domiproject DF). | Diagnostics in progress:
|
F34 | The voltage is not normal (less than 180V). | Wait until the network is restored, or use a stabilizer. |
F35 | Mismatch in the current of the control board and the network. | Consider the correct parameter when replacing the board (50-60Hz). |
F37 (yellow light blinks). | The pressure in the system has decreased. | Make sure that the boiler is not leaking. Check for leaks. Replace the heating relay. |
F39 | The outdoor thermometer has closed. Thermistor malfunction. | Tighten pins, insulate damaged wiring. Install a new thermometer. |
F40 | System pressure is above normal. | Take out the filter of the relief valve, wash it from blockage. If the valve is defective, the equipment must not be operated. Replacing. Ensure that the expansion tank is performing its functions. |
F42 | Overheating and temperature sensors display different data. | Measure the resistance of the DHW thermistor. Normally, the readings should be 10 kOhm. Put a new item. |
F43 | The heat exchanger safety system has been activated. | Diagnostics of the circulation pump. Removing excess air from the system. |
F50 | Problems with gas fittings. |
|
fh | Air is being circulated by the circulation pump. After three minutes, the code will disappear. |
There are other problems that are not indicated by codes and are not described in the instructions:
- Small flame in the burner. Adjusting the pressure on the burner, it is necessary to clean the nozzles from dust and dirt;
- Burner starts arbitrarily. The nozzle needs to be cleaned, a broken thermocouple is being replaced. The fuel valve coil is checked for an open;
- Hot water does not heat up. Reduced pressure in the line. It is necessary to adjust the power, cleaning the heat exchanger from scale;
- Flames flare up. Cleaning the combustion chamber, burner. Traction Check
Most errors block the operation of the boiler. Even if it restarts after a restart, do not let the problem go by its own accord. It is necessary to find out the causes of its occurrence and contact the master or solve the problem yourself. Regular maintenance prevents malfunctions and prevents contamination of equipment parts.
