Default worcester bosch boiler pressure

I have a worcester bosch boiler, whose pressure dial is all over the

just in the green zone.

It's been behaving this way for many months.

Is this a problem with worcester bosch boilers in particular, or
boilers in general? When we get a British Gas engineer to fix it, he
increases the pressure so it's in the green zone. After a few weeks
it's fallen again into the red zone.

The boiler is ten years old. Can it be fixed? Should I be looking at a
new boiler? Apart from the pressure dial, the boiler is fine.

It's probably a failed expansion vessel
