vaillent Combi Boiler?

Hi,
I have the usual system needs repressurising every year, but now I have an 'over pressure', where my pressure is off the scale. I've checked the part where i normally repressure, to make sure that it is fully off, and am at a loss what to do next. THe manual only covers loss of pressure. Its been like this for a week, and doesn't seem to be doing any visual or audible harm. Any infor much appreciated

It doesn't appear to be discharging outside, its almost as if the gauge has broken and gone off the scale

How do I find the filling loop, and would it be called anything else (theres' no index at the back of the boiler manual ?

I have a Turbo Max Plus 824/8 E

Many thanks,
Anthony

Disconnect the filling loop just cos it looks off does not mean the check valve is not passing

is wsater discharging from the pressure relief valve to outside...as the safety discharge is set at 3 bar

it looks like your loop is passing or your pressure gauge is u/s...it could be the e/v but you have posted insufficient info to diagnose...try the loop first
