Mend Glo-worm 30CI Heating Pressure Overheating

how can i fix my glo-orm 30ci boiler?

my glo-worm 30ci boiler first started showing DL on the display and is now showing f1 faults and nbody seems to know what these mean, which is no help to myself as i now have no heating or hot water, and have not had any since the weekend, water pressure is going above what it should do, so looks like boiler is overheating any advice

F1 is 'Ignition Lockout' ie. either no gas or no flame detection

As for the system water pressure, that boiler should not foault on this until the water is outside of 0.5 - 2.7 bar pressure.
Normal system cold pressure should be about 1-1.5 bar, if when hot it exceeds 2.5 there may be also a problem with your expansion vessel.
