Currently in Guarda, Portugal and bathroom door handle has fallen off. MH is a 2020 Knaus Sun. Looks as if the retaining grub screw has disappeared and handle has gradually loosened. Would be very grateful for any assistance with removing circular plate inside handle to access screw heads and re-fasten to door. Photo 1 shows the plate. It does not appear to be threaded or an interference fit. If the circlip is removed I will be unable to replace it once screws are tightened. Photo 2 shows handle with missing grub screw and Photo 3 where it fits on the door.
I would be most grateful for any suggestions.
