Combi Boiler issue
I had a Baxi 800 system installed last July.
It has recently started making a banging noise and then the heating turns off. Water still works fine. It has been flushed and the plate heat exchanger has been changed, but issue still persists. I have been advised the radiators are breaking down. Please could someone offer further advice or opinion
It may be the low carbon pump burnt out doesn’t take much or it could be a blocked auto air vent ect
You could possibly have a air lock on system
Or possibly a blockage in pipe work
I suggest venting system of air. If that fails try power flush
