Make sure the unit is plugged into a working outlet and that the machine switch is in the "On" position if the unit will not start. Reset the circuit breaker to the home if it is switched to the "Off" position and that the switch is rated for the voltage of the machine.
Check that the water supply hose plugged into the machine is properly connected and turned on if the machine runs but there is no water coming from the unit. Inspect the nozzle of the pressure washer wand and look for clogs or debris that may prevent the wand from shooting out water. Wash it according to the instructions provided with the machine.
