Dripping drinking water tap.

Anyone familiar with this drinking water tap, Liff touch tap, N-CP1 ?
It does not look as though the tap dismantles, assuming there is a washer in there.
Any view would be appreciated.

Can't remember exactly how but I have had one apart and changed the washer. It didn't last thugh so we changed it for the type with a knob.

Thanks for the reply. I have been able to contact the supplier. The spout has to be unscrewed to gain access, and they supply a repair kit.
First snag, mine has been installed close to the wall and cannot be unscrewed, so I have to dismantle the tap.
Second snag, my pet hate, a plastic nut onto a metal thread.
