Why is my Nilfisk-Advance ConvertaMAX 28 leaving water behind?

  If your Nilfisk-Advance Floor Machine isn't picking up water well, several things could be the cause. Check for worn or torn squeegee blades and reverse or replace them if needed. Ensure the squeegee is adjusted correctly so the blades touch the floor evenly. Empty the recovery tank if it's full. Secure or replace a leaking recovery tank drain hose cap. Replace the recovery tank cover gasket if it's leaking, and make sure the cover is seated properly. Also, clean the squeegee tool to remove any debris, clear any clogs in the vacuum hose, and adjust the solution control valves if you're using too much solution.

  If your Nilfisk-Advance Floor Machine vacuum shuts off and the display shows “FULL” even when the recovery tank isn’t full, the issue might be a plugged squeegee hose. Clear any debris from the hose. It could also be due to vacuuming large amounts of water at a high travel speed. Try slowing down.

  If your Nilfisk-Advance Floor Machine isn't scrubbing well, the issue could be due to a worn brush or pad. Try rotating or replacing the brushes. The wrong type of brush or pad or the wrong cleaning chemical could also be the cause. Consult Nilfisk-Advance for the correct type. Moving the machine too fast or not using enough solution may also cause poor scrubbing performance. Slow down, and adjust the solution control valves.

  If your Nilfisk-Advance Floor Machine has inadequate or no solution flow, start by filling the solution tank if it's empty. Then, flush the lines and clean the solution filter if the solution lines, valves, or filter are clogged. Make sure the solution control valves are open and clean or replace the solution solenoid valve if necessary.

  If your Nilfisk-Advance Floor Machine has inadequate or no solution flow, several issues could be the cause. First, check the solution tank and refill it if it's empty. Ensure the main solution flow control valve knob is turned on. Another potential cause is clogged solution filter, valves, and hoses, so you should clean them. If these steps don't resolve the issue, the solution solenoid valve (L1) may be defective and require replacement. For solution system faults in the main controller A2*, refer to the Main Control Board Troubleshooting Guide in the Electrical System of this manual.

Why Nilfisk-Advance ConvertaMAX 28 has no solution flow?
- T
  Thomas PhamAug 28, 2025
  There are several reasons why your Nilfisk-Advance Floor Machine might have inadequate or no solution flow. It could be due to an empty solution tank, so check and refill if necessary. The main solution flow control valve knob might be in the off position, so ensure it is turned on. Clogged solution filter, valves, or hoses can also cause this issue, so clean them thoroughly. A defective solution solenoid valve (L1) could also be the culprit, requiring replacement. For solution system faults in the main controller A2*, refer to the Main Control Board Troubleshooting Guide in the Electrical System of this manual.
