My Baxi inset 50/5 locks out (red flashing light) when the boiler stat is above 1/4 and the room stat switches off. All zone valves and pump are working correctly, I have drained, refilled and bled the radiators and it doesn't do this when it switches off on hot water stat. It has done this since my local friendly heating engineer fitted it, he has no idea why.
Baxi inset 3 overheating ?

To KEVPLUMB,
I didn't go to baxi because I think it's a problem with the way it has been plumbed in not the boiler.

if it's fitted as per the mi's there should be no problem
