replaced bathroom rad yesterday and had to drain the system from the valves in the bathroom to cut and shorten pipes now my boiler will start up then turns off after about 20 seconds.has my boiler got an air lock? the reset button on the side is solid so i don't know if its in the normal position or is solid stuck out it must be a self topping up system as there is no bar gauge or loop that i can see on boiler
