pressure was low on boiler greenstar 28i Set the pressure to 1.3 as recommended and although heating and hot water work every day or two the boiler needs reset..blue flashing light..even though its still works. Only takes few secs to rest it but whats causing it? Any help?

depends on how fast the light flashes and when it's happening. check the fault finding section in the instructions.
