Pump not getting electricity - is this confirmed by taking off the wheelarch liner and checking the harness connection to the pump in the screenwash reservoir?

Sorry - brain freeze. What I meant to say was 'do the wipers cycle when you press the button on the end of the stalk'
There's a similar thread here by spuddio that he tracked down to F7 (15A) in the drivers facia fusebox, but he had other issues also:

Failing that, it's a case of tracing the wiring from the pump back through connector LF1 to the body processor module. One other possibility is the grounding to the stud LF1AR (shown in GGG's diagram). JTIS shows it adjacent to the RHS headlamp.

windscreen washer pump
I have checked the number 7 fuse 15 amp driver's side facia it's ok I also checked the fuses in the engine compartment number 7 30 amp its ok as well ,neither the windscreen washer or the headlamp washer is working ,the wipers seem to function correctly,even when I press on the button at the end of the stalk they cycle as they should do but als no liquid to be seen anywhere, as we say in France "a l'aide" I don't know how to check the relay "powerwash " how does one check a relay?

You know, something just occurred to me. I've seen several wires solder joints come lose and disconnect with age on the end of the headlight stalk. I would imagine the price of a new wiper switch is just as shocking as the headlight is.
Given that you may want to pull the steering wheel and have a look. Ok stick with me here: I was about to delete this suggestion thinking if the wipers cycle, the momentary switch is sending a signal to start the was cycle. Who would design a switch with 2 separate wires to start this automated cycle?
I am on a phone without glasses so can't review thediagrams. Since this event (squirt, wipe, wait wipe) is a coordinated layered event it must be managed by a module.
I think we may have just proved your switch and it's wires are ok by the fact that the wipers energize. I don't see how the switch would have 2 separate wires but do check the diagram to be sure.
My next step would be to read "trigger" voltage at the relay for the pump while someone presses the button. If no voltage present, provide some to ensure the pump works.
