My Intergas 36/40 boiler (7 years old) has recently started showing the 0.0 fault code and reads a CH pressure of 0.0 when I turn it off. No work has been carried out on the boiler or radiators and it has been working with no problems.
I have tried to increase the pressure through the refill valve but no change in pressure occurs.
I have also bled the radiators (no significant air released).
Prior to taking the steps above, the central heating would still work when required, but now the CH is permanently off.
Any thoughts or help much appreciated.
