Intergas Xtreme and Xclusive boiler error codes
Fault Code | System Behaviour | Possible solution / cause |
F000 | Sensor defect | Heat exchanger sensor needs replacing. |
F001 | Temperature too high during central heating demand | Air could be in system, central heating system needs bleeding. There could be an error with the pump & it could need replacing. |
F002 | Temperature too high during domestic hot water (DHW) demand | The wiring of DHW sensor needs checking, possible breakage. |
F003 | Flue gas temperature too high | Heat exchanger needs checking for contamination. |
F004 | No flame during startup | Gas valve is closed. Condensation drain is blocked and ignition needs checking. |
F005 | Flame disappears during operation | Condensation drain could be blocked, the air supply duct and flue needs checking for possible recirculation or blockage of flue gases. |
F006 | Flame simulation error | Gas valve could need replacing or burner controller could need replacing. |
F007 | No or insufficient ionisation flow | Wiring of ionisation/ignition pin could have a breakage shut down and could need replacing. |
F008 | Fan speed incorrect | Fan cable needs checking, fan or burner controller could need replacing. |
F009 | Bunner controller has internal fault | Burner controller needs replacing. |
F010 F011 | Sensor fault | Possible issue with heat exchanger sensor, breakage or not connected properly. |
F012 | Sensor 5 fault | Wiring for flue gas sensor needs checking, possible breakage. |
F014 | Mounting fault sensor | Heat exchanger sensor is not mounted correctly and needs to be mounted properly. |
F015 | Mounting fault sensor S1 | Central heating flow sensor is not mounted correctly and needs mounting properly. |
F016 | Mounting fault S3 | Domestic hot water sensor is not mounted correctly and needs mounting properly. |
F018 | Flue and/or air supply duct is blocked | The flue and/or air supply duct could need cleaning. |
F019 | BMM error | Check the BMM wiring for breakages / BMM wiring could need replacing. |
F027 | Short circuit of outdoor sensor | Outdoor sensor could have a wiring issue, check and replace the outdoor sensor. |
F028 | Reset error | The reset button needs checking for unintentional operation e.g. cleaning of control panel. Burner controller might need replacing. |
F029 | Gas valve error | Gas valve needs checking for leakage/burner controller could need replacing. |
F030 | Sensor S3 fault | Check wiring of domestic hot water sensor for breakage or shutdown domestic hot water sensor – it could need replacing. |
F031 | Sensor fault S1 | Check wiring of central heating flow sensor for breakage and shutdown. Check that weather central heating flow sensor is connected correctly. |
