Reseting a Biasi boiler

To reset a Biasi Boiler-

    -Press and hold the reset button until the red light turns off
    -You may then see a burner light switch on, to show your boiler has fired up again

  2. If your boiler uses a thermostat control knob to reset:

    -You’ll know your boiler is in lockout when you see a red light either flashing or constantly lit
    -To reset, turn the temperature control knob completely anti-clockwise
    -Hold until the red light goes out
    -Turn back to your normal setting
    -Again, a burner light should come on to show that your boiler has fired up again

  3. If your boiler has an ON/OFF/SELECTOR switch:

    -Open the fascia display
    -You may see an error code, or (if you have a boiler without a display screen), a flame failure light
    -Turn the selector switch to the R (‘reset’) position
    -Hold for five seconds before releasing
    -The error code should change, or the flame failure light should stop flashing
    -The burner light will turn orange to show that your boiler is working again

Common Biasi Boiler Problems

ProblemPossible Cause
No heat or hot waterBroken diaphragms and airlocks, failure of motorized valves, issues with the thermostat, or low water levels
Leaking and drippingThe most common cause is a broken internal component but it will depend on where the water is leaking from
Banging, whistling, or gurgling noisesA common cause is air in the system, alternatively, it could be that the water pressure is too low or it’s kettling
The pilot light goes outCould be a broken thermocouple that is stopping the gas supply
Losing pressureThere could be a water leak in the system, the pressure relief valve needs replacing or the radiators have been bled recently
Frozen condensate pipeYour boiler should display an error code or warning notification
Thermostat issuesThe thermostat may be turned off or not set to the correct settings (time etc.)
KettlingLimescale or sludge building up on your boiler’s heat exchanger
Radiators not getting hotSludge or air build-up in the system or unequal distribution of heat
The boiler keeps switching itself offCould be low water pressure, a problem with the thermostat, or a lack of water flow due to a closed valve, the air in the system, or the pump not circulating the water in the system correctly
