Too much pressure in combi boiler

My pressure on boiler Main combi 30 is too high. How can I reduce it? There is a pressure release valve inside the boiler but I can't see how to get the front off?

Hi nickmachin,

The thing to do is connect a hose to one of your drain off valves on one of your rads, open the drain off valve and there you go .........
