Self diagnose your boiler faults.
Intergas boilers are one of the UK's less heard about boiler manufacturers. Intergas with unrivalled quantities of hot water and heat with its patented two-in-one heat exchanger is one of the best in the world. But if you don't look after your Intergas boiler, by giving it an annual boiler service, it will eventually develop a fault.
While Intergas boilers are extremely reliable appliances, Intergas boilers only have 2 common faults. #1, One being a common fault that every boiler has and that is a blocked condensate pipe. #2, Two is an error code 1 on the display which is very simple to fix and you shouldn't need one of our gas engineers.
The reason why your intergas boiler is showing a error code 1 (Overheating) on the display is because of air in the system. Having air in the system can prevent water from circulating around the heating system. To remove this air, you need to bleed your radiators one by one. Or get one of our boiler repair experts to help out.
Depending on what boiler model you have, intergas boiler warranties are between 3 and 10 years. If your boiler was installed by one of our gas engineers we can extend the boiler warranty of up tp 12 years.
Fault/Error Code | Possible Cause |
---|---|
1 | Overheating - Fault code 1 means that the boiler temperature is too high / The appliance becomes too hot, there is insufficient flow and may result in excessive pressure. You can do a DIY fix by bleeding your radiators. |
4 | No ignition - Fault code 4 means that no ignition flame signal has been detected. The burner does not light. Check that the gas tap is open. If not, open fully. Press the reset switch. The appliance will then restart. A Boiler Engineer is required. |
5 | Weak ignition - Fault code 5 means that a weak ignition flame signal has been detected. |
6 | Flame error - Fault code 6 means that an ignition flame detection error has occurred. |
Fault/Error Code | Possible Cause |
---|---|
F000 | Sensor - Heat exchanger sensor needs replacing. (Replace S1 and/or S2). |
F001 | Overheating - 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 might need replacing. Pump setting too low, check setting. You need a Boiler Engineer for this repair. |
F002 | Overheating - Domestic hot water (DHW) demand (Replace S1 or S2- Check cables) The wiring of DHW sensor needs checking, possible breakage. |
F003 | Overheating - Heat exchanger needs checking for contamination. You need a Boiler Engineer for this repair. |
F004 | Startup Fault - Gas valve is closed. Condensation drain is blocked and ignition needs checking. |
F005 | Flame Fault - Condensation drain could be blocked, the air supply duct and flue needs checking for possible recirculation or blockage of flue gases. |
F006 | Flame Fault - Gas valve could need replacing or burner controller could need replacing. |
F007 | Fault - Wiring of ionisation/ignition pin could have a breakage shut down and could need replacing. |
F008 | Fan Fault - (Fan catching on casing- Check cable/replace fan.) Fan cable needs checking, fan or burner controller could need replacing. |
F009 | Internal Fault - Burner controller needs replacing. |
F010, F011 | Sensor - Possible issue with heat exchanger sensor, breakage or not connected properly. |
F012 | Sensor - Sensor 5 Wiring for flue gas sensor needs checking, possible breakage. |
F014 | Sensor - Heat exchanger sensor is not mounted correctly and needs to be mounted properly. |
F015 | Sensor - Sensor S1 Central heating flow sensor is not mounted correctly and needs mounting properly. |
F016 | Sensor - Sensor S3 Domestic hot water sensor is not mounted correctly and needs mounting properly. |
F018 | Fault - The flue and/or air supply duct could need cleaning. |
F019 | Fault - Check the BMM wiring for breakages / BMM wiring could need replacing. |
F027 | Sensor - Outdoor sensor could have a wiring issue, check and replace the outdoor sensor. |
F028 | Fault - The reset button needs checking for unintentional operation e.g. cleaning of control panel. Burner controller might need replacing. |
F029 | Fault - Gas valve needs checking for leakage / burner controller could need replacing. |
F030 | Sensor - Sensor S3 Check (faulty gas valve relay) wiring of domestic hot water sensor for breakage or shutdown domestic hot water sensor – it could need replacing. |
F031 | Sensor - Sensor S1 Check wiring of central heating flow sensor for breakage and shutdown. Check that weather central heating flow sensor is connected correctly. |
