If your Global Industrial floor scrubber is not dispensing water, there could be several reasons for this issue. Here are the most common causes and troubleshooting steps:
1. Water Tank is Empty
- Cause: The water tank may be out of water or not filled properly.
- Solution: Check the water tank and refill it with clean water. Ensure the tank is seated properly in its compartment.
2. Clogged or Dirty Filters
- Cause: Filters in the water system might be clogged with dirt or debris.
- Solution: Locate and clean the filters. Refer to your scrubber’s manual for their exact location.
3. Blocked or Kinked Hoses
- Cause: The water delivery hoses could be blocked or kinked, preventing water flow.
- Solution: Inspect the hoses for kinks, clogs, or damage. Straighten or replace them as necessary.
4. Pump Issues
- Cause: The water pump may be malfunctioning or not working at all.
- Solution: Listen for the pump running when the machine is in use. If it’s not, check the electrical connections to the pump or consider replacing the pump.
5. Faulty Solenoid Valve
- Cause: The solenoid valve controlling water flow might be stuck or faulty.
- Solution: Inspect the valve for blockages or electrical issues. Clean or replace the valve if needed.
6. Control Settings
- Cause: The water flow settings might be too low or off.
- Solution: Check the control panel and ensure the water flow is set to an appropriate level.
7. Airlock in the System
- Cause: Air trapped in the water lines can block water flow.
- Solution: Bleed the system by running the machine and allowing water to flow through until the air is expelled.
8. Tank or System Leaks
- Cause: A leak in the water tank or delivery system could be preventing proper water pressure.
- Solution: Inspect the machine for visible leaks and repair or replace damaged parts.
9. Dirty Nozzles or Jets
- Cause: The nozzles or jets dispensing water may be clogged.
- Solution: Remove and clean the nozzles using a fine needle or compressed air.
10. Electrical or Wiring Issues
- Cause: Wiring or electrical connections related to the water system may be damaged.
- Solution: Inspect the electrical connections for corrosion, loose wires, or damage.
