A clogged solution filter is one of the most common causes of reduced or no water flow. Turn off the machine. Close the solution valve if applicable. Locate the solution filter. Carefully remove the filter bowl or filter screen. Rinse away dirt, debris, and detergent buildup. Reinstall the filter securely. Open the solution valve and test the machine again. Tip: Regular filter cleaning can help prevent future water flow problems.

Inspect the hoses running from the solution tank toward the brush deck. Look for: Kinked or pinched hoses Loose connections Debris inside the hose Damaged or collapsed hoses Make sure all hoses are properly connected and water can move freely through the system.

Dirt, detergent residue, or debris can sometimes restrict the water path. Check the solution tank outlet, filter, hoses, fittings, and water outlets near the brush deck. Clean any visible buildup or blockage before testing the machine again.

Depending on the model, your floor scrubber may use a manual valve or an electronic solenoid valve to control water flow. Make sure all electrical connections are secure and inspect the valve for visible blockage or damage. If you suspect an electrical problem or a failed solenoid, contact technical support before replacing components.
