Washers not working - pipework issue?

[HPsauce]

Bit of a rubbish day on the road yesterday, 7.5 hours total driving, of which over 6 was fortunately in the S8 - mostly in Friday traffic jams and awful weather (rain, sleet, snow, hail etc. etc.).
The first two hours (outward trip) were not bad, just the odd snow shower, and the wipers and washers worked fine. Well, not quite 100% as one jet (far nearside one) was a bit blocked, but three and a bit were adequate.

But at the start of the way back the washers failed, at first a tiny dribble then nothing. Topped up to be sure but not a drop on the screen. Headlight wash was working fine. Over 4 hours in crap weather and jams so it wasn't great.

Checked this morning and the pump is running, sounding normal. Water is pouring out under the car, coming down both sides - presumably from the scuttle drains.
A quick look in the scuttle (what of it you can see) and there's evidence of fresh bubbly dampness. It's been dry overnight here.

Conclusion - split or disconnected tubing to the jets. But where to start to investigate?
What has to come off (and how) to see what is wrong?

Get somebody else to operate washers while looking under bonnet yourself to see if you can spot the leak.

Job done in under a minute. Thanks Ainars.

Dragged SWMBO from her warm cell to do the honours in the driving seat. She was out until 1am in London last night and is a tad fragile due to lots of wine and nothing else!

Leak was under the cover bottom of windscreen, drivers side. Popped that off (it's just clipped in) and could see the feed pipe from the pump had slipped off a connector, next to what I presume is the wiper motor.
Pushed it on well over the retaining "bulge" and it's all working.

It's a bit of a stretch so may well work loose again, but next time I'll know and slap a small cable tie on it. Or even cut the pipe and add another connector to give a bit of slack. I think I've got some squirrelled away somewhere.
