Claim 0:
1. A pressure washer comprising:
a pump having a relatively low pressure fluid inlet and a relatively high pressure fluid outlet;
an engine coupled with the pump for driving the pump;
an electric starter for starting the engine, the electric starter is one or more of engageable with an input shaft of the pump and mounted to a pump housing;
a flow sensor configured to provide a control signal in response to detecting fluid flow through the pump; and
a controller configured to actuate the electric starter in response to the control signal when the engine is not operating, including providing a pulse width modulated current to the electric starter, the controller further providing engine fault detection including monitoring a voltage detected at an engine magneto and discontinuing automated starting upon detection of one or more of no voltage and an insufficient voltage indicating a locked rotor exception to avoid an overcurrent event in the electric starter.
