If I remember rightly the spout is only held on with an "O" ring...This is the same for the main body....Grip the swiveling part of the tap, rotate back and forth, applying upward pressure, and it should pull off. I imagine the micro switch 's under there. If I'd seen this yesterday, I would have brought a spare one home to take appart, as I was at my van...
But looking at the picture in Towshure's catalogue...
The water pipes must push in, and the white plastic disk on the bottom must lever out with the aid of a small screwdriver...Best of luck..
TOP TIP
Get yourself a spare, so that if you mess up it's not all downhill. I know it's not cheap, but what the hell
