Step by step troubleshooting Step 1: Make Sure the Brush Is Operating Before checking the water system, make sure the brush is operating normally. The water system should be tested while the brush is running. If the brush is not operating, troubleshoot the brush system first before continuing with the water flow checks below. Step 2: Check the Water Valve Check the water valve and make sure it is in the open position. The valve is open when the valve handle is parallel with the water line/pipe. If the valve is closed, turn it to the open position, start the brush, and check whether water begins flowing to the brush. Step 3: Check and Clean the Water Filter Locate the water filter in front of the water valve and check whether it is clogged with dirt or debris. If it is clogged, remove the filter housing, clean the filter screen inside, reinstall it correctly, and test the water flow again. Step 4: Check the Fresh Water Hose Inspect the fresh water hose for any blockage that may prevent water from reaching the brush. If the hose is clogged, clear the blockage and make sure water can flow through the hose normally, then reconnect it and test the machine again. Step 5: Check the Solenoid Valve Wiring Locate the solenoid valve and check the two power wires connected to it. Make sure the connectors have not come loose and inspect the wiring for visible damage. If a connection is loose, reconnect it securely; if the wiring is damaged, replace the damaged wiring harness. Step 6: Check the Solenoid Valve If the wiring is secure, confirm that water is reaching the inlet side of the solenoid valve. Then disconnect the fresh water hose from the outlet side of the valve, turn on the brush, and check whether water comes out of the valve. If water reaches the inlet normally but no water comes out of the outlet while the brush is operating, the solenoid valve is faulty and needs to be replaced.

Low water flow is often caused by a partially clogged filter, restricted hose, buildup in the water outlets, or a low water flow setting. Clean the solution filter and inspect the hoses and outlets for restrictions.

This may be normal. Some floor scrubbers are designed to stop dispensing solution when the machine stops moving or when the brush system is disengaged. Check the operating instructions for your specific model.

Uneven water distribution can be caused by a partially blocked hose, fitting, outlet, or solution manifold near the brush deck. Inspect and clean the water distribution path.

Inspect the solution filter regularly and clean it whenever you notice reduced water flow. Machines used frequently or with detergent may require more frequent cleaning.

Use a low-foaming commercial floor cleaning solution suitable for automatic floor scrubbers. Avoid highly corrosive chemicals or products that may damage tanks, hoses, seals, valves, or other components.

Follow the recommendations in your machine’s manual. Avoid excessively hot water, which may damage tanks, hoses, seals, or other components.
