Abstract
A pressure washer is provided with a flow control switch and a bypass passage. The flow control switch shuts the motor of the pressure washer off when fluid is not being supplied to the pressure washer or when the spray gun of the pressure washer is closed. The bypass passage relieves excess outlet pressure and activates the flow control switch when the spray gun is closed. The pressure washer may include a soap pump for injecting soap into low pressure fluid at the inlet of the pressure washer.
