How to fix GreenWorks GDC40 Pressure Washer that has low pressure?
- K
  Kevin ScottAug 14, 2025
  If your GreenWorks Pressure Washer isn't reaching high pressure, several factors could be at play. Start by checking the garden hose diameter; it should be 1” (25 mm) or 5/8” (16 mm). Ensure the garden hose isn't blocked and that the water supply is fully open. Verify the nozzle is correctly installed on the spray wand. Lastly, inspect the water inlet filter and clean it in warm water if it's blocked.

Why is my GreenWorks GDC40 Pressure Washer motor buzzing but not starting?
- J
  Jennifer WhiteAug 21, 2025
  If your GreenWorks Pressure Washer motor buzzes but doesn't start, it could be due to a few reasons. A discharged battery pack needs to be charged. If there's remaining pressure in the system, stop the machine, pull the gun trigger to release the pressure, and then restart the machine. There also might be remaining friction in components. To resolve that: disconnect the water supply, turn the machine on for 2 or 3 seconds, and repeat several times.

Why does the output pressure of my GreenWorks Pressure Washer fluctuate?
- A
  Albert MartinezAug 26, 2025
  The fluctuating output pressure of your GreenWorks Pressure Washer can be due to several reasons: insufficient water supply (fully open the water supply and ensure the garden hose isn't blocked), air in the pump (ensure hoses and fittings are secure, turn off the machine, and pull the gun trigger until a stable water flow emerges), a clogged water inlet filter (clean it in warm water), a depleted battery pack (charge it), or calcified components (operate distilled vinegar through the detergent tank).

  Misty StewartSep 1, 2025
  If your GreenWorks Pressure Washer motor buzzes but the machine won't start, it could be due to a depleted battery pack (charge it) or remaining pressure in the system (stop the machine, pull the gun trigger to release pressure, then restart the machine). If you haven't used the machine for a long time, speak to a person of an approved service center. If there is remaining friction in components and you can hear a hum, disconnect the water supply, turn the machine on for 2 or 3 seconds, and repeat this step several times.

Why does my GreenWorks GDC40 Pressure Washer have inconsistent pressure?
- M
  maxwell01Sep 5, 2025
  Inconsistent pressure in your GreenWorks Pressure Washer can stem from several causes. First, ensure your water supply is fully open and the garden hose isn't blocked. Air in the pump can also cause this; check hoses and fittings, then turn off the machine and pull the trigger until a steady water flow emerges. A clogged water inlet filter requires cleaning in warm water. A depleted battery pack needs charging. Finally, calcification in the gun, hose, or nozzle may require running distilled vinegar through the detergent tank.
