I tried to use the washer bottle to clean the screen (as you do) and, although you could hear the washer motor working nothing happened. OK, just re-fill with water (although it didn't seem that long ago since I'd done it, and it's a *big* bottle to fill).
So, put more water in, attempt to clean windows, hear pump going, after about 30 seconds water gets flung at the windscreen. Great, perhaps it had run so low that there was no water left at all along the pipework, thinks I.
That wouldn't appear to be the case, I tried to clean the windscreen yesterday, same scenario whereby you can hear the motor working but nothing comes out. Checked the bottle (in case there was a leak), totally full. All the connections that I can see appear to be ok, no splits or anything.
Anyone any idea what could be at fault? Is there a possible pump failure?
