Screenwash leaking into drivers foot well

Hi All, 
the screenwash in my wife’s Citigo is leaking into the drivers side footwell whenever it’s being used. I had a look and it seems to go through the dashboard, very close to the fuses near the steering wheel! I think it’s the hose feeding the back windscreen wash but I don’t know where it is ..or how easy it is to access

any ideas?

Many Thanks

Graeme
