baxi 105e combi pressure @ 3.0 bar?

replaced pcb board and 3 way motor valve today still the same. fully drained down expanssion vessel pumped it up to 3/4 bar as it had no air in it. refilled system still the same,3 radiators not working now. boiler working better now but still pressure gets to 3 bar, takes 1 hour instead of 4 mins to get to 3 bar
now have no hair, any other ideas or suggestions thanks

i would say your expanssion vessel may need charging back up

With only the hot water on it reaches 2.5 bar with pre heat on full and then the boiler shuts off. if I put the heating and the hot water on it goes up to 3 bar
