vaillant ecotec plus 824r1 high pressure advice

[Unregistered]

I have the above boiler - the pressure bar is in the red but I can't find anywhere in the manual which shows how to lower the water pressure - Does anyone know please? Thank you

The easiest way Is to bleed the excess pressure out via the bleed screw on a radiator or a
drain off point which will be quicker if you know where they are and how they work.

Before you do this, can you confirm if it goes into the red when the heating is hot or cold?

It could be the filling loop is faulty or slightly open or the expansion vessel has failed.

It's on red with the heating off. Only noticed that there is very limited hot water this morning, checked the pressure and it's 2.8 bars, have bled all the radiators but there was no air, just water coming straight away...
there are two switch/levers underneath the boiler that say closed, could it be that one of these is loose, didn't want to fiddle with them as it doesn't mention them in the manual?
i have homecare cover on my boiler with brisitsh gas but didn't want to call out just yet if it was something I could do...
