Thanks very much. I’ll have a look at the website properly after work. I’m in the south west, about an hour from Bristol.

The saga continues. Iwata suggested I apply beeswax to the base of the nozzle and threads around the nozzle cap, didn’t help. I’ve also checked the nozzle, needle, nozzle cap under magnification and I can’t see anything that would cause concern. At this point I’m considering a warranty claim through Iwata, from a glimpse at their website I believe I’d have to send it to the US? Do Iwata have any UK based repair/service centres that can deal with warranty claims?

Update - I gave the needle a tiny extra push when I re-assembled the airbrush. At 40 psi it seemed to start operating normally again. Went back down to 20psi and no flow again but now very slow bubbling in the paint cup. One bubble every 5-10 seconds.

I got the smallest amount of water through at 40psi, I held the airbrush against a dark surface whilst spraying and couldn’t see the cone, but definitely got some liquid out. That was with the trigger as far back as it would go.

Thanks both I definitely have the right size nozzle (.35) the front o ring doesn’t appear to be damaged. Air flow is as normal, and the needle moves. There is no bubbling back into the paint cup however which I believe would indicate a blocked nozzle.

Hello all. A while ago I had a issue with my iwata hp-cs where I had paint flow whilst only pressing for air. Eventually I bought a new nozzle. Problem solved. I now have air flow but can’t get anything though the airbrush, even water. I have stripped and cleaned many times and always disassemble and clean at the end of each session. The needle doesn’t appear damaged and moves back and forth. When I take the nozzle out I can see through it. Really stumped. Any help appreciated
