How to fix a GreenWorks Pressure Washer when the motor will not start?
- T
  Timothy FosterAug 13, 2025
  If your GreenWorks Pressure Washer motor won't start, make sure the On/Off switch is in the “ON” ( | ) position and squeeze the gun trigger. Also, check that the power cord is properly plugged in. If you're using an extension cord, it might be too long, not the proper gauge, or damaged; replace it with a 25’ (7.6 m) or 50’ (15 m) 14 AWG cord. The electrical outlet might not be providing enough power, so try a different outlet. Finally, if the pressure washer circuit breaker tripped, allow it to cool before restarting.

Why GreenWorks 51142 Pressure Washer doesn't reach high pressure?
- J
  Jessica JacobsAug 17, 2025
  If the GreenWorks Pressure Washer doesn't reach high pressure, ensure you are using a 1” (25 mm) or 5/8” (16 mm) garden hose, as a smaller diameter can restrict water flow. Inspect the garden hose for any kinks, leaks, or blockages that may be limiting the water supply. Fully open the water source to ensure adequate water supply. Check that the power nozzle is in the high-pressure position. If the pump is sucking air, turn the machine “OFF” and purge the pump by squeezing the trigger until a steady water flow emerges through the nozzle.

  If the output pressure of your GreenWorks Pressure Washer varies from high to low, first ensure that the inlet water supply is sufficient by fully turning on the water and checking the garden hose for kinks, leaks, or blockages. If the pump is sucking air, turn the machine off and purge the pump by squeezing the trigger until water emerges steadily from the nozzle. Check the discharge nozzle for obstructions and clear any debris with a fine needle. If you suspect calcification in the gun, hose, or power nozzle, run distilled vinegar through the detergent tank.

Why GreenWorks Pressure Washer motor buzzes but fails to run?
- A
  Antonio SheaAug 25, 2025
  If your GreenWorks Pressure Washer motor buzzes but fails to run, first, verify that only the pressure washer is running on the circuit to ensure adequate supply voltage. If there's residual pressure, turn the unit “OFF”, squeeze the trigger on the spray wand to release the pressure, and then turn the unit “ON”. Unplug any extension cords and plug the unit directly into the outlet to avoid voltage loss. If the pressure washer has not been used for a long period, call the Toll-Free Hotline. In case of residual friction among components, disconnect the water supply and power ON for 2 to 3 seconds, repeat a couple of times until the motor starts.

  If there's no water coming from your GreenWorks Pressure Washer, first, check that the inlet adapter (G2) is attached to the machine’s water inlet and the quick connect coupler (G1) is attached to the garden hose, ensuring the quick connect assembly is not reversed. Then, make sure the water supply is turned ON. Finally, check the garden hose for any kinks and remove them.

Why is the pump noisy on my GreenWorks 51142?

  If the pump of your GreenWorks Pressure Washer is noisy, ensure that all hoses and fittings are airtight to prevent air from being sucked into the pump. Turn off the machine and purge the pump by squeezing the trigger gun until a steady flow of water emerges through the nozzle. Also, check the water filter for clogs and rinse it in warm water if necessary.
