Glowworm 30cxi pressure fault

[cookienumberone]

Hello, I dont know if anyone can help me but i have pressure problem with my boiler.
the pressure reading is only showing 0.4 bar and if i turn the blue knob under the boiler to increase pressure i can hear water filling but the pressure gauge does not increase.
if i leave boiler for 1 day then switch back on the pressure will sometimes read 0.5 bar and then work again for a couple of days.
I think it might be a pcb fault. can anyone help

are you sure the water is going in? Those filling devices are prone to failure and also won't work properly under 1.5 bar. I'd recommend fitting a standard external one and trying that. Also, would check that the low water pressure switch isn't blocked up. won't be pcb

i think water is going in because the overflow pipe was leaking outside so i assumed that the system is filling.
does this still mean it wont be PCB

could be a blocked pressure sensor
