Phil :

Hi,This is risky business in the blind, not responsible for damages on your end. Click 'accept' when satisfied.. or we can get another expert.

Phil :

If the units pressure relief is allowing that, and not releasing, then its common with that unit OR the pressure relief valve has failed.

Phil :

Do this, find the pressure relief valve inside the unit and lift its manual release lever as a test.. do this when the boiler is at 3.5 bar..get back to me with the results.
