Rear wash non functional

I am not getting any water to the rear wash jet on my e-tense 300 4x4. I can hear the pump running when it is operated but no fluid is visible at the jet end.
I assume i have to remove the wheel and inner wheel arch to access the pump. Has anyone else had this problem, if so how dis you cure it?

I assume you’ve checked for a blocked jet ?
If not have someone operate the washer while you insert a small pin into the jet , not too hard just a little bit of pressure and moving around.
I would of thought if you can hear the motor spinning and theres no water dripping from underneath , the next thing to check is to see if the jet is clogged.
The of the car gets dirty with all the road muck getting thrown up, it dont take much to clog up the jet.

Have look on ground under car, maybe broken or disconnected tube. Stone hit my front window, after replacement front jet was not working. The tube near wipers wasn’t inserted correctly and disconnected.
So after finding small pond under car I fixed problem on a parking lot within minute.
