Hello
Expert:  JamesI replied 1 month ago.

F1 is a generic fault stating its having issues lighting (not very helpful).

I read that online
Expert:  JamesI replied 1 month ago.

With this type of fault it often points to issues with the gas supply, gas valve or flame sensor within the boiler.

When was the boiler last serviced, when you start the boiler do you see the pilot light come on (and if so how long)

I have gas on my hob. Dunno when it was serviced as we just bought this place but BG said boiler is 8 years old. Right now the screen is dark with f1 blinking. When I press reset it lights up and starts for a bit; then screen goes off again and back to f1. I vent find how to actually turn it off. What is pilot light?
Expert:  JamesI replied 1 month ago.

Ok you need to reset the boiler, by switching it off and on again using the switch next to the control panel.

The LED above the control panel should go green this is telling you the pilot light is on, on other models you can see the flame through the panel but this one is covered by the outer case.

If the light goes green then to red it tells you its not sensing the flame, if its going straight to red it points towards a gas valve which isnt letting the gas into the boiler.

Let me know the outcome and can talk you through your options.

I have restated several times. When clicking restart the screen turns yellow but then goes off again, see images
Expert:  JamesI replied 1 month ago.

Ok this suggests its a flame sensor failure which is a hardware fault (not user error), the part is around £30. However you will need a gas safe engineer to attend to strip it down replace the part and recommission the boiler.

If you would like me to recommend a local engineer please provide your postcode.
