Firebird Boiler Error Code Solutions
Firebird Boiler Error Codes | |
Fault | Possible Cause |
E1 | Control thermistor fault |
E2 | Flue thermistor fault |
E3 | Flue thermistor fault |
E5 | Burner fault (possibly burner lockout) |
Thermostat at a high limit (cuts off) | Reset boiler |
Problem | Possible cause | Do you need an engineer? |
---|---|---|
No heat or hot water | Can be caused by several things including broken diaphragms and airlocks, failure of motorised valves, issues with the thermostat or low water levels | Yes |
Leaking and dripping | Most likely to be a broken internal component but it will depend where the water is leaking from | Yes |
Banging, whistling or gurgling noises | Air in the system could be causing this, otherwise it could be that the water pressure is too low | Yes |
Pilot light goes out | The thermocouple could be broken which is in turn stopping the gas supply | Yes |
Losing pressure | Could be a water leak in the system, the pressure relief valve needs replacing or due to recently bleeding radiators | No, unless there’s a leak |
Frozen condensate pipe | This fault should be displayed on your boiler as an error code or warning notification | Yes |
Thermostat issues | Thermostat could be turned off or not set to the correct settings (time etc.) | Consider replacing |
Kettling | Limescale or sludge building up on the heat exchanger | Yes |
Radiators not getting hot | Sludge or air building up in the system or an unequal distribution of heat | Your radiators will need to be bled which doesn’t require an engineer but if you don’t feel like carrying out the task yourself |
Boiler keeps switching itself off | Could be low water pressure, a problem with the thermostat or a lack of water flow due to a closed valve, air or the pump not circulating the water in the system properly | Yes |
