How can I get my combi re pressured?

Turned hot tap on in bathroom to run for a while and got hot water through. Fired up on turning hot tap on and could see pilot light this time ignite,had not seen before.Flicked switch to central heating and guage went up but could not hold,dropped back down again and when turned running water off cut out again.

Your filling loop may not letting water, either low pressure or non return valve may be jammed thus water not pass through
