Hi, that is the fault code for insufficient water pressure. What is the pressure on the boiler gauge?It should be 1.2 bar . If below 1 bar it won't fire up. There will be a filling loop,usually on the pipework under the boiler. It is a flexible hose with a tap/taps at each end.open the taps till the gauge is at the right pressure
