Pressure rise?

Hi can anybody have any ideas regarding the climb in pressure on a solaris 30c
It climbs to 2.9/30 on the c/h side then the blue light flashes I then turn it off, leave it for 30 mins then I have to turn it back at a lower c/h temp
to get it to work, any tips

regards sammy

Either filling loop letting by or faulty expansion vessel

Built into the boiler is an oblong expansion vessel,there is an air valve that should be accessible,open pressure relief valve to drop the pressure in the central heating system,then check the air pressure in the expansion vessel
as you would a car tyre then if needed pump up to 1.0 bar If pressure starts to increase again when its running the expansion vessel could need replacing
