Paul. Thanks very much for the info. System pressure now restored after many months of head scratching.

Hi I have a leak coming from the relief valve manifold push in connector, which is held in with a clip. What part is needed? washer - 'O' ring?

Hi, look under the boiler and remove the white metal grille. put the white filling key into the hole just to the left of the grey plastic filling tap. the filling key has to be pushed so the end locates on the slots at to top of the hole. then turn the key about 90 degress and then turn the grey filling tap untill you can hear the water going in. Keep an eye on the pressure and try not to let it go above 1 bar. Once finished turn off the tao and remove the key. Good luck!

there should be a filling loop(silver braided pipe) under the boiler one end of the pipe will have a slot or a tap turn this until ur boiler reaches 1.5 bar then turn of the tap,failing this then you should have a white key that slots under the boiler reffer to the instructions or go to worcesters web site
