Damn screen wash

[jherman]

2017 XC60 (new model)
Rear wash hasn't worked for months and months, and despite temporally recovering from a blip on the front screen wash, the front washers don't work either. In fact, now I cannot even hear the pump working.
Read on here about blocked non-return valve at the back and so I accessed the pipes and indeed the NRV was choked with white matter. Cleaned it, when to try it out.....blade swishes but no obvious sound from the pump (it used to audible in the early days). Checked the fuses and nothing blown. I wondered if the ?blocked from wipers were the cause of the pump failure, so tried to tackle the front wipers (aqua blades).
Foolishly I took the blades off, in service position and thought I'd see if some water come out the arms. Went to activate the wipers....as they went to move (in service position) they fouled on the bonnet and smacked straight down onto the windscreen (without any blades) and CRACK goes the windscreen!
So now I have no working wipers, no obvious noise from the pump and a cracked windscreen!
