  Dan HarrisAug 26, 2025
  If you're experiencing little to no solution flow, it could be due to a few reasons. The solution tank might be empty, so refill it. The solution flow rate may be set too low; increase it. Also, the solution tank filter could be clogged, so clean it. Try flushing the solution supply line if it is plugged. If the scrubber is ec-H2O model, try restarting the machine and setting flow rate to high.
