Hi Guys, can you help?

My front screen jets werent working well and i was getting dirty smear from the water that did come through.

The reservoir was full of gunge/filth so I took it out, cleaned it and emptied it. I then cleared through all the tubing and pushed a pin through the jet holes.

Now everything is reconnected and the reservoir has clean water in it but nothing is coming through at all. Not even the small squirt I had before.

I can here the motor/pump going and i checked the tubes and jet holes again.

Whats going on?
What should I do?

Thanks in advance
