Boiler pressure too high can't lower it.

[wizardsnipple]

Hi folks my partner has a Greenstar 30Si boiler, the pressure is just below 3 bar but for the past year or so water has been slowly dripping out of the overflow pipe. I've bled the radiator upstairs and downstairs drained about 2l out but the pressure doesn't drop at all. Any ideas? Thanks.

It looks like this underneath I've had a search online can't find any info about where you'd fill it.

The filling loop maybe in the old airing cupboard/ anywhere
