My 2009 Vauxhall Astra 1.7 diesel ECO4 windscreen washer system won't work?

My 2009 Vauxhall Astra 1.7 diesel ECO4 windscreen washer system won't work. The pump operates, well you can hear the motor turning, and the bottle has water in it. The fluid is not frozen and I have cleaned the jets. I susspect that there is debris in the bottle, pump and or tubes. Is there a filter that can be cleaned.
