Having read lots of threads on this topic, I went down to my garage this morning brimming with confidence!
Although my 'intensive' washer system is working fine, the 'regular' one is not. (But both windshield nozzles spraying fine.)
The pump also appears to be working (and the headlight washers).
I tried disconnecting the relevant hose from the T-shaped check valve (assuming the problem may be with the valve). But, on pumping, no fluid came through the hose.
So I disconnected the hose at the reservoir tank end. (The fluid drained out - albeit rather slowly.)
The hose (now disconnected at both ends) is clear.

Any suggestions on where to go from here?
Am I going to have to pull the reservoir tank?
First you need to ensure the pump runs; remember that there are two pumps at the reservoir - the headlight washer is independent. Next check the W/W fuse: if it's OK, then probably the stalk switch. If the pump runs, does it feed fluid into the Int Wash bottle? The likelihood is the non-return valves which will need to be fixed or replaced. There is a good diagramme in PET.
Then disconnected the two pumps (one for the headlamps, one for the windscreen) and the water level sensor.
De-scaled / cleaned everything up.
By swapping the two pumps / connectors, I've been able to deduce that both pumps are working fine. The problem is an electrical one - the feed to the windscreen pump has no power!
Now my inexperience is showing...
The diagram inside the fusebox suggests the two pumps share a 40-amp fuse, which is fine. (I know it's fine because the feed to the headlamp pump is working.)
The connector itself (at the pump end) looks OK - it's the black one in this photo.

What next?! Any help gratefully received...
Have you checked for an output at the wiper stalk, if not, that's got to be your next option. I had a similar problem when I bought mine (years ago). I rebuilt the switch and all has been OK eversince. The switch was built with rivets securing the halves etc together I replaced those with small nuts and bolts..

Reason: spelling
Both windscreen washers and headlamp washers now working!
When the paint shop re-connected the pumps, they obviously put the connectors back the wrong way round.
Took me a while to work this out (starting at the nozzles, back through the T-valves, through the hoses, back to the reservoir, then the pumps, then the electrical connections!) but all now sorted.
Then I forgot that the headlamps need to be on for the washers to work! So all good. Thanks for your input and advice.
