vaillant vuw gb 242 1e pressure keeps going up

[nommy]

Hi all im not very good at these things but am willing to give it a go. i have an issue with my vaillant boiler as the overflow is leaking at the side of my house and when i have looked the pressure gauge is just over the 3 bar which is obviously to high. I have no idea how to try and relieve this pressure i was told to try and empty some water out of the system through the radiators so i tried this but the pressure drops to 0 but when i turn my boiler back on it slowly rises to just above 3 again. ive looked in the manual but have no idea where the pressure relief valve is and the valve that builds up the pressure is closed. As i said im not great with this type of thing but any advice would be great as i really need my overflow to stop leaking at the side of my house.
any suggests grateful
thanks

model of my boiler is vaillant turbomax vuw gb 242/ 1e, 282/1E hope that helps in anyway

Fill loop valves are bypassing, disconnect loop to check,
