Mend Main Combi 24 HE Boiler Pressure Relief Water

boiler pressure?

Main Combi 24 HE the pressure went above 3 and the relief valve went off. I released the pressure by letting water out of the radiator and it went back to between 0.5 & 1 bar. I turned on the heating and it has gone back up to nearly 3 bar again. What is the problem
