Ferroli Modena 80E problem

[Fountain]

Hello, the ferroli modena boiler is working fine for about twenty minutes then it stops, and the green light goes out. If we unplug it and leave it for a few hours, then plug it in again it works as before. Recently we have changed the long venturi, the ntc sensor and the flow meter. My brother thinks it may be due to a connection getting hot and disconnecting, but said to see if anyone has had this problem on a forum.

May be an APS problem. I have changed numerous venturis and air pressure switches on these as I used to work on alot of them.

as above if only one venturies been replaced then the other needs doing,this boiler is a cheapie but its lack of parts can be its strength
