Ok will have a look thanks for your help, wish the people you call out were as good as you , I always get the morons claiming to be boiler engineers

Yea it still does it when on hw only, had someone out but I wasn’t convinced he new what he was doing, he wants to replace pcb board and control switch

It’s a combi boiler no zoned heating is 3 way valve in boiler as no external like the old days

Unless I isolate the boiler the heating is on all the time, fault started that if you had hot water running then heating was on as well but now you have to isolate boiler power to stop the heating, any ideas please
