Troubleshooting Tips

• Pressure Washer Won't Start: Check the engine oil and gasoline levels. Ensure there are no clogs in the fuel line and the spark plug is functioning.
• Low Pressure: Verify that the water supply is turned on fully and that there are no kinks in the hoses. Clean or replace the nozzle if clogged.
• Pump Leaking Water: Tighten all connections. If the leak persists, inspect the pump seals and replace if necessary.
• Pump Overheating: Make sure the thermal relief valve is functioning properly. Avoid running the pump in bypass mode for extended periods.
• Engine Struggling: Ensure the pump's pressure setting matches the engine's capacity. Adjust the unloader valve as needed.
