How do you remove the w/s washer bottle from a new model nissan xtrail?

I managed to get some muck in my windscreen washer bottle after topping it up with a dirty watering can.

Now all the jets are blocked and Nissan want £100 to repair it. So I could really do with taking out the washer bottle and swishing it out and I can blow the lines out to clear the muck.

The truck is a new model X-trail 2.0 diesel.

All help and advice much appreciated
