Oil boiler pressure Help

I take you mean water pressure?
Lift the top cover off and there might be a braided flexible hose there with and valve at each end. One in cold mains in the other connects to the heating circuit via the flexi hose. Fill until pressure gauge reads about 1 to 1.5 bar cold then turn off and fire up the boiler. Pressure should go ne higher than say 2bar once heated.
 
Hi thanks, yes its is the water pressure sorry, as for a top cover the unit dony have one just the front panel and pipes that you can see in the photo.. Cheers
 
The white cover on the top of the boiler, probably on sprung clips. If the flexi is not there it wil be somewhere else on the system close to the boiler, maybe in a cupboard.

Take off the top cover, follow the cold water inlet pipe and there will be a'tee' from it that has one end of the filling loop with a tap. Follow the braided hose from this tap to the other tap, open both taps yntil the pressure equalizes, then close them.
While you are about it, think about renewing the seals on the DHW connections before you have to buy another pump!!!!
