Ferroli F30

[nick34]

I have a Ferroli F30 boiler. Over the summer i noticed the water bar pressure was a bit low so i used the blue valve under the unit to increase the pressure a bit. But i must have increased it too much and now its +4 and the pressure warning light comes on. How do i reduce the pressure? I can't see any other obvious valves to turn

just vent some water out of a rad till u get back to the desired pressure

I have vented the radiators twice (and got quite wet i may add) and the pressure came down but then a little later the pressure gauge increases back up again. Any ideas?

The valve either isnt shut properly or is passing....

Worst case, the heat exchanger is now passing
