Vokera compact 24 problem

Hi I've a fault with my Vokera combi boiler at the present.

The hot water side of the system appears to work fine, but when the central heating is used the system looses pressure.

I dont belive its a leaky (central heating system) pipe as I have tried pressurizing up the system to 3 bar whilst only using the hot water, and the system held this pressure fine for week.

The pressure appears to drop when using both the central heating and hot water at the same time. Could the heat exchanger be faulty?

not much info here but its probably the expansion vessel.

read the FAQ's about it and dont pressurise the system to 3 bar again.
