Solo nozzle dripping not spraying

I have successfully used the Solo 2 gallon sprayer for about 7 years; however, the nozzle doesn’t spray any longer.  It only drips; there isn’t a mist.  I have removed the brass nozzle and filter in an attempt to clean them, but with no success.  Do you have any other suggestions?

First, try without the filter to see if it will spray. If yes, then that means the filter is clogged. At that point, try soaking the filter overnight to see if it unclogs. Fine debris can easily clog it and sometimes you won’t see it. If it won’t spray when the filter is removed, it could be the ball and spring. At that point, we usually replace the nozzle.
