An industrial floor scrubber is a powerful cleaning tool designed to keep large areas spotless and safe. However, one of the most common problems operators face is when the machine stops dispensing water properly. Without a steady flow of water, the scrubber cannot loosen dirt and debris effectively, reducing cleaning efficiency.
In this article, we’ll explore the most common causes of water system issues in industrial floor scrubbers and provide easy fixes to get your machine back to work quickly.

1. Clogged or Blocked Solution Tank Filter
Over time, dirt, dust, and debris can clog the filter in the solution tank. When this happens, water flow slows down or stops completely.
Quick Fix:
-
Remove the filter from the solution tank.
-
Rinse it thoroughly with clean water.
-
If the filter is damaged, replace it with a new one.
2. Kinked or Damaged Water Lines
Water lines inside the scrubber may bend, kink, or crack, preventing water from reaching the scrub head.
Quick Fix:
-
Inspect the hoses for bends or blockages.
-
Straighten out any kinks.
-
Replace damaged hoses to restore proper flow.
3. Faulty Water Control Valve
If the control valve is malfunctioning, it may fail to release water when the operator activates the scrubber.
Quick Fix:
-
Check the valve for dirt buildup or mechanical failure.
-
Clean the valve or replace it if necessary.
4. Low or Empty Solution Tank
Sometimes the issue is as simple as forgetting to refill the solution tank. If the tank is empty, no water will be dispensed.
Quick Fix:
-
Refill the tank with clean water and the recommended cleaning solution.
-
Double-check that the tank cap is secure.
5. Pump or Electrical Malfunction
Some industrial floor scrubbers use a pump system to push water through the lines. If the pump is damaged or the electrical system fails, water will not flow.
Quick Fix:
-
Listen for the sound of the pump when the machine is turned on.
-
If silent, check the electrical connections and fuses.
-
Replace the pump if it is defective.
Preventive Maintenance Tips
-
Regularly clean filters and hoses to avoid buildup.
-
Always use clean water and the recommended detergent.
-
Inspect the scrubber before each use to catch small issues early.
-
Schedule routine maintenance for long-term reliability.
Final Thoughts
When your industrial floor scrubber stops dispensing water, it doesn’t always mean a costly repair is needed. In most cases, the problem can be traced to simple issues like clogged filters, kinked hoses, or an empty tank. By following the quick fixes above, you can restore water flow and keep your machine performing at its best.
