hello. When my boiler is on the radiators are getting hot and I have hot water. But the pilot light keeps cutting out and relighting every 6 seconds or so. My pressure looks like it's in between 1-2.
Pressure should be 1 bar cold Should the pilot light be lit all the time?? Get a gas safe engineer to take a look unless you know what you are doing you are putting yourself and others at great risk DIY gas repairs are all good until someone gets hurt or things get damaged and then your not insured/getting prosecuted
Sounds like it's not modulating correctly so could be air switches,pressure switches,flow sensors,flame detection or gas valve not responding properly, fan not at speed etc lots to look at you need someone to strip it down and diagnose what is causing the fault
