Tried to differentiate from the other windscreen washer post, but my washers are barely pushing out any pressure. Had it a few years ago and the service center said they blew some air down the pipes and whatever they did sorted it.

Going to give it a go, anybody have any idea how to disconnect these pipes in the picture please?...

 

 

Solved, turned out with the bonnet up and spraying the washers, water would pour down from the spray outlets, pulled the insulation off and found that both washer jets had come apart from the pipe. Washer unclips from the bonnet with a good wiggle and pull and simply push the pipes back on. Had to unclip the electrical connection to get enough length to get the pipe back on though. Added a zip tie to help as this has happened before.
