The most common cause of blockage is hard water encrustation at the nozzle. It's unlikely to be in the line itself, and
that's easy to check (unplug hose for nozzle, run washer, water should come out of the hose).
To clean the stalagmites out of the nozzle, remove the nozzle (it's quite fiddley) and soak in EdFred or CLR tile cleaner. I've done it a couple of times, and I need to do it again.
If it should turn out to be the hose that's plugged, I think I'd try Weed Whacker string.
