You're missing the model of the boiler, so that we can advise you further.....

There may be disturbed dirt which has blocked the gauge.

It MAY come back to a reading after a few hours.

Iso valves under boiler turned on?

Sorry the model is a sime friendly.I've drained some water out of the rads and refilled them ok.it just doesn't seem to fill boiler.could there be an air lock somewhere.

For those who don't know, that Sime is definitely not a friendly boiler!
