Can someone please help me, i have drained down central heating system to repair leaking radiator. When i have refilled system boiler will not restart, fan runs for 2/3 seconds then F1 fault code comes up, in manual this code relates to ignition problem. Have done everything in manual but still no luck.

Turn off power for three min and try again.
Are you quite sure the gas supply is connected and has not been turned off under the boiler or anywhere else ???
If not then I suspect that for some reason its giving a wrong code.
Its most likely to be associated with water flow/air in the system.
If the boiler was left powered with the system drained then its possible it has tried to start up and has tripped a manual o/h stat.

Thanks for advice Tony, have tried turning off for 3 mins still no luck, i did shut boiler down before commencing work. When i advance heater timer central heating pump runs for a couple of seconds but then stops, fault code and red light then show on boiler control panel. Would trapped air in system cause boiler not to ignite? Have bled rads and there does not seem to be any trapped air in pipes. Any more advice would be appreciated, Thanks.

Have unscrewed large chrome screw on pump and water came out, cant listen for air as the pump literally spins for 3 seconds before stopping. There is air vent above pump which is secure. Really dont know what else to try as boiler was working perfectly well this morning.

I take it you have pressed the reset button?
The cap seems to be fixed correctly and not just loose. Cap is about the size of your finger end, would this be cap we are talking about?
In reply to Scatman there seems to be no reset button on this boiler, manual says to reset by switching off for 5 seconds then switching back on. Have tried this numerous times and have left for longer periods.

Or am i mistaken?

Nothing on this boiler, only one sliding switch off and on,one mode button in middle and two buttons either side all other modes are displayed on the digital display.
