BIASI Gas Boiler Error Codes

If the alphanumeric figures flash in the navigation display in the BIASI Binova models, and in the Rinnova models you can observe the same process on the control panel screen - this indicates that you are experiencing some kind of malfunction in the gas heating system. In most cases, you just need to press the Reset button to restart the automatic system. But there are situations when you just can not do without specialized assistance.

If the letters E are flashing on the screen or the display, and with them the numbers and the unit does not turn on, then you can restart the system and continue to operate the machine. Below are the most common errors in which the operation of the device is blocked.

Error E01 - Stopping the device due to incorrect ignition. Check the function of the gas valve, the supply gas pressure.

Error E02 - Faults related to the thermostat. Check the operation of the sediment, the stop valve, the temperature sensor of the thermostat.

Error E03 - Blocking the functions of the unit. Check the mains voltage and earth.

Error E04 - The pressure in the heating system has increased. Check the functioning of the circulation pump, the serviceability of the manometer.

Error E05 - Unit blocking associated with traction. Check the serviceability of the fan, the thrust sensor. Inspect the chimney or venturi pipe.

Error E06 - The temperature sensor of the heating system is faulty. Check the electrical network, make sure the NTC sensor is operating correctly.

Error E07 - The temperature sensor of the water supply system is damaged. Check the electrical network and the operation of the NTC sensor in the DHW system.

Error E08 - External temperature sensor blocking. Check the electrical network and the operation of the external NTC sensor.

Error E11 - The occurrence of a parasitic flame. Check the operation of the gas valve. Inspect the mains and check the ductility.

Error E14 - Blocking associated with the movement of the coolant. Check the operation of the circulation pump and NTC sensor of the heating system.

Error E20-23 - The electromagnetic solder is defective. Check the mains and the valve.

Error E24 - Incorrect burner operation during ignition. Check the gas pressure and the presence of electricity.

Error E25 - Problems with gas supply during operation. Check that the connection is correct, the flue is open and the manometer is working.

Error LC 26 - Blocking associated with increasing the power of the flame. Check correct installation, burner operation, gas pressure, and chimney.

The error codes are instantly transmitted to the display. Therefore, you will immediately be notified of the problem. All of the above problems can be eliminated by pressing the Reset button. But there are cases when on the display to the above is added another figure or symbol (most often these are working tools). In this case, you should contact a qualified technician to inspect the unit. All the fault values are reduced to the fact that you will need to replace the part. For example, fault E05 (Thrust Lock) is displayed. The boiler is switched off and there is a tool symbol on the display. Then you should call the master to replace the draft sensor or fan, or clean the chimney.
