Hi after some advise on a Warmflow Combi

Boiler works correctly on hot water, Flick switch on boiler onto heating and trips mains rcd! most often straight away, can run up to about a minute before tripping, pumps working as should, seems to heat up correctly when running ie, no air, good flow,
No leaks on electrical conections,
fautly pressure swicth?? not sure, didnt try linking it out?

OP, the pressure switch is, as said, a switch.
Think logically mate.

whats up with it then?

I suspect the team thinks your a rocket scientist and having a go at fixing something you know nothing about, which could lead to problems with combustion or electrical safety etc etc, so they have decided to leave it at that.
