Why does my GreenWorks Pro GPW 2300 motor buzz but not run?

If the motor of your GreenWorks Pro Pressure Washer buzzes but fails to run, verify that only the pressure washer is running on the circuit, as the supply voltage might be below the minimum. The system might have residual pressure; turn the unit “OFF”, squeeze the trigger on the spray wand to release pressure, then turn the unit “ON”. Voltage loss due to an extension cord could also be the issue; unplug any extension cords and plug the unit directly into the outlet. Also, residual friction among components might be the reason. To fix this, disconnect the water supply and power ON for 2 to 3 seconds, repeat a couple of times or until the motor starts.
