I have recently changed my pump from a Myson CP53 to a Grundfos 15/50 when I came to turning the system back on the boiler a Potterton Profile 40E starts up OK but then trips out after a couple of minutes and it wont reset until I turn the electrics back off. could this just be a case of an airlock in the system or something more.
Any help would be great.
Thanks
