Just for the archives, the built in filling loop for this boiler operates as follows: Shove the plastic key up into the hole to the right of the white plastic nut, turn clockwise (it locks at about half a turn). Then turn the white plastic nut anti clockwise to fill the boiler. Simple enough, but no mention of stage 2 in the documentation. Thanks to Ed's FAQ I got the gist of what any self respecting manufacturer would have made clear in the user guide.
