ferroli combi pressure problem

[senga]

Ferroli Optima. Decided to check combi yesterday for water level. Pressure was down below 2. Opened filler & let pressure rise to 2.5.

This morning turned on hot water but got none, checked pressure again & it was down almost to zero, filled again & noticed overflow/safety release valve was running outside & trickled away until pressure was almost zero again.

Anyone who knows what my problem could be, everything was ok until I topped up yesterday.

Why are you trying to run the system at 2.0. Except on a 3+ storey house, 1 would be normal.

From your description it sounds like the expansion vessel has failed.
