COMBI 105E BOILER PRESSURE TO HIGH?

Hi, I have a COMBI 105E,the boiler pressure is to high, the relief valve is blowing off continuosly, the filler loop valve has been changed and also the diaphrams on the differential valve and diverter valve.The boiler is still functioning.
Anybody got a clue as what part is faulty.

sounds like your expansion vessel is de-pressurised or faulty, you should get a pro to check this fault out.
