Why is no solution reaching the brush of my Nilfisk-Advance Floor Machine?

  If the solution isn't reaching the brush on your Nilfisk-Advance Floor Machine, several factors could be at play. Start by checking the solution filter for clogs and clean it if needed. Also, ensure the solution tap isn't closed or partially closed; if it is, replace it. A broken solenoid valve or an electrical connection issue could also be the culprit, in which case you should replace the valve or repair the connection. Finally, inspect the solution tank and hoses for any debris that might be obstructing the flow, and clean them accordingly.

  If the solution continues to flow to the brush of your Nilfisk-Advance Floor Machine even when the machine is turned off, it might be due to dirt or calcium deposits on the solenoid valve gasket, requiring a cleaning. Alternatively, the solenoid valve itself might be broken and need replacement.
