Vw diesel bluemotion polo 2012 - which is the windscreen washer fuse?

My washers won't work and I can't here the motor engaging and so I assume it is the fuse or the motor is broken. Can anyone guide me to the right fuse? Would I be right in thinking halfords would be a good quick source as I use the car for long motorway journeys daily.

FYI for bluemotion fans my best mpg in this bluemotion polo was 93mpg from centre of Manchester to centre of Birmingham.

Help getting a quick fix appreciated.
