Why does my GreenWorks GPW2000-1 Pressure Washer pressure go up and down?
- JJoel WallaceJul 29, 2025
If the output pressure of your GreenWorks Pressure Washer fluctuates, ensure that the water supply is fully open and check the garden hose for any kinks, leaks, or blockages. Also, make sure that only the pressure washer is running on the circuit. Clean the water intake filter by removing it and rinsing in warm water. Finally, make sure that the hoses and fitting are air-tight. Turn "OFF" machine and purge pump by squeezing trigger gun until a steady flow of water comes out the spray tip. If the gun, hose or nozzle are calcified, run distilled vinegar through detergent tank.
