I have a Baxi 35/60 with a low pressure or pump fault (warning light activated). I have changed the hydraulic outlet assembly, as the push rod was not activating the microswitch, but the boiler fails to start (pump does not start) and the warning light continues to flash. The boiler fires up when the microswitch is activated manually and the pump appears to work, the system pressure does, however, rocket up. Is this likely to be the result of an air lock? and if so, how would one remove it? or could it be a problem with the pump?
