What to do if there is inadequate or no solution flow in my Nilfisk-Advance Scrubber?
- MMichael JosephAug 19, 2025
If your Nilfisk-Advance Scrubber isn't dispensing enough solution, or no solution at all, several factors could be at play. First, ensure the solution tank is adequately filled. Next, verify that the main solution flow control valve lever is set to the 'on' position. A clogged solution filter, valves, or hoses can also impede flow, so inspect and clear any obstructions. If these steps don't resolve the issue, the solution solenoid valve (L1) might be defective and require replacement. Finally, a solution system fault in the main controller A1* could be the cause, so it should be checked for faults.
