2.. Central to the bonnet are 2 large diameter  jubilee  clips, loosen  these..(there is a sensor probe   residing  in  the  middle.

3.  On  the  left hand side 2 clips hold the feed tube,  unclip these . (These are next to the heater   insulation box and more or less central to the bonnet halfs. Watch out as there is an O ring there as well.

4. The stainless filter tube housing can now be persuaded off  the 2  grommets at the bottom base and  slid  past the grommets at  the right side  vertical.  This now allows the filter tube housing in a friendly position and allows the filter to be  removed.
