BoilerFaultCodes
The most common Biasi faults
Your boiler has failed to ignite or has lost its flame, which means it has locked itself out for safety.
Check that your gas supply is turned on and other gas appliances have fuel.Press and hold the Reset button for 2 to 3 seconds until the error clears.Ensure the condensate pipe (the plastic pipe outside) isn't frozen if it is currently winter.
Your boiler has sensed that it is becoming too hot and has shut itself down as a safety precaution.
Wait 15 minutes for the boiler to cool down fully.Turn the selector switch to the 'Reset' position for a few seconds, then back to the heater/tap icon.Check that your radiator valves are open and that the system pressure is between 1 and 1.5 bar.
Your boiler has detected a problem with how it disposes of waste gases or brings in fresh air, causing it to shut down for safety.
Check the outdoor flue pipe for any obvious obstructions like bird nests, leaves, or debris.If it is freezing outside, check if the white plastic condensate pipe is blocked with ice.Press and hold the reset button for 5 seconds to see if the error clears.
Your boiler has detected low water pressure in the system, which prevents it from firing up to provide heating or hot water.
Locate the filling loop (the flexible silver hose) underneath the boiler.Slowly open the valve or valves on the filling loop until you hear water entering the system.Monitor the pressure gauge until it reaches between 1.0 and 1.5 bar, then close the valves tightly.Press the reset button to clear the fault code.
Your boiler has stopped working because it has detected a specific internal electrical fault or a sensor communication error that requires a manual reset.
Locate the selector switch on the front control panelTurn the switch to the 'Reset' position for 5 to 10 secondsTurn the switch back to the 'On' (Heating or Hot Water) position and wait for the boiler to restart
Your boiler has likely detected a circulation or temperature issue that has caused it to lock out for safety.
Locate the selector switch on the front panel and turn it to the 'R' position for 5 seconds, then back to the on position.Check that your system pressure is between 1.0 and 1.5 bar on the pressure gauge.Ensure all radiator valves and isolation valves are fully open to allow water to flow.
Your boiler has detected an electrical configuration error and cannot operate safely, meaning you will have no heating or hot water until it is reset or repaired.
Locate the selector switch on the front control panelTurn the dial to the 'R' (Reset) position for five secondsTurn the dial back to the 'On' position and wait for the boiler to restart
Your boiler has detected that the water inside the system is getting too hot, causing it to shut down for safety.
Check that all your radiator valves are fully openEnsure the boiler pressure gauge is between 1.0 and 1.5 barReset the boiler by turning the control knob to the 'R' position for 5 seconds
