I have a Potterton Suprima boiler which connects to the Megaflow. Today it started to have an issue as the boiler keeps shutting off and needs resetting. It seems that water is not flowing round the primary flow and return. The pipes are really hot at the top of the boiler so I assume that there is no flow round the system which is causing the boiler to overheat and trip out.
The pressure on my external expansion vessel is fine and I there are no leaks. Am I too assume that the pump could be faulty as it seems more noisy than usual as there is no flow around the primary circuit ( I thought that maybe even if the pump was faulty the hot water would still work its way around, but maybe not.
Can you get airlocks on pressurised systems.
Thanks
