Mend Baxi Duo Tec 30 Combi Boiler Pressure Leak

Decrease pressure baxi combi boiler?

Hi I have a problem with a 3yr old Baxi combi Duo Tec 30 - no special filling loop - just valves. Pressure has become high on more than one occasion as well as dropping on a cold frosty night. Have happily ncreased pressure from time to time and once have reduced pressure by taking water out of radiator. But now often seesm to be high pressure. Can't find a leak but I suppose it may not be visible? Or am I not turning round valves off tightly enough??

Had it serviced last November and don't particularly want to call out again because of cost.

Would love some help!!!

not clear information, is presure zero when cold and high when heating hot than is pressure vessel,or if high all times than either filling loop not closed properly, best way checking is open silver flex pipe and see if driping, if not than leave out and reduce pressure from rad air key and check again, if still rising than may be plate heatexchanger may be leaking within, check by stop cold water to boiler and than see and will be able to figure it out where is problem
