Combi boiler

[waltone]

I have a7 year old combi boiler that has started to lose pressure on the central heating side. I have changed the safety pressure relief valve and it is still dropping and shuts down around 5 or 6 hours after filling up again. At the moment I cannot see any leaks in the rads or pipe work, so is there anything else in the boiler that might cause the pressure to drop. I have an Ideal Logic 24. I cannot see any wetness inside the boiler as if might be leaking in there. I am starting to run out of ideas. any help would be greatly received .

Main heat exchanger leaking down the condensate. Needs a gas safe engineer to replace it . Stop meddling inside the boiler.
