I have just replaced a water pressure sensor on a Glowworm

Customer Question

I have just replaced a water pressure sensor on a Glowworm 24ci combi boiler. I did this in response to a F9 fault code. I still have no pressure registering on the digital gauge, can you let me know what is causing the boiler to cut out and continue to display the F9 fault code. Dave
