I have a Ferroli Optimax HE Plus 31C Boiler which is just over

This answer was rated:

I have a Ferroli Optimax HE Plus 31C Boiler which is just over 5 yrs old so now out of warranty. The boiler is over pressuring and when I drain the radiators to bring the pressure down, as soon as I stop it goes back up. It is ejecting water constantly through the overflow outside, but presently is running both hot water and heating ok and is showing no error code on the display.
Hi , the issue is the expansion vessel in the boiler. This takes up the expanded heated water. It must be flat or split. It will need recharging or replacing
