So weird one maybe. I have just been watching my boiler (I know its a slow day) and I set my flat for heat demand and my wife was in the kitchen. watching the start up sequence for heating and all is going well, then wife opens tap and hot water demand comes on screen. all good. she closed the tap. and boiler looks like it shut everything down.
it says DHW mode pump overrun. then that eventually goes off screen and it says heating mode start. and the cycle starts again.
I tried 3 or 4 times with the local tap and yep. it appears to me the heating mode stops when I close the hot water demand.
any idea, do I need to get my plumber in?
