Where is it leaking steam from? If it is from the porta-filter, you need to replace the group head gasket, which is done with something like a screwdriver to get it out.

I have a brewtus lll-V (9 months old). yesterday, it began emitting a constant sound of hissing steam from the top/rear of the machine, with occasional belches of an airy popping sound, that registered...

That sounds more like a safety valve issue than the vent valve, that is poping because of too much pressure, try lowering the pressure stat on the machine, or replacing it.

Safety valve cn10 keeps activating about 10 seconds after switch on. any ideas anyone. stafco markus 2 group semi auto

Try this open the steam wand and leave on when turning the machine on, when valve stats hissing with steam close. If that works then the vent valve needs to be replaced, If it blows out hot steam from valve then the pressure stat is not operating properly.

How can I increase the pressure for the steam wand?

If boiler pressure is set to about 1.2 bar on machine and you are getting no steam then check the nozzle on the steam wand, that might be blocked, before adjusting the pressure stat in the machine.

I wish to lower the steam pressure slightly how do I do it. Many thanks

Inside the machine their is a presurestat which is connected with a pipe to the boiler and inside the pressurestat their is an electrical contactor which turn on and of the heating element. this pressurestat have an adjusting screw on the top which have he signs + and - if you turn it to - then you will reduce the presure insite the boiler. However the normal pressure should be between 1.2-1.3 bars.
