ideal independent c24 F1 Fault, but pressure is high

Hi guys, I've just spent the last half an hour going through the fourm trying ot find someone with my problem but no luck.

I have a C24 combi showing F1 fault, the pressure is high if anything - just over 2 when it should be 1.5.

Any idea how to make this error go away? I turned it off and on again whcih worked a couple of times, giving hot water, but not working anymore

Many thanks!

You can try relieving some pressure via a radiator but ultimately I think you are going to need a gas safe engineer out

also sometimes p/gauge sticks giving a false reading of system pressure. give the gauge a harshish tap on the front to see if it drops back.
