Ferroli Combi 77 FF P boiler problems

[ChrisReed]

I have a Ferroli Combi 77 FF P boiler. For some time, it has been running for a few minutes/seconds, then cutting out, before restarting. The result is that we are often without hot water or heating.
Two engineers have told me that is because the water pressure is below 1 Bar (it is consistently showing 0.6-0.8 Bar). The mains flow was very low, so I have had a new main installed by Essex & Suffolk Water. The flow is now very strong, but it has had no effect on the boiler. I now see from the instruction manual that the boiler should be topped up with water (something none of the engineers have suggested).
Can someone tell me where to go from here, please?

you need to find an engineer who know their stuff Im afraid as if its worked previously with low water flow then it should still do so, so its an issue with the boiler still
