1. An oven comprising: a housing providing an oven cavity accessible through a door which may be opened and closed about the cavity, the oven cavity including a heater for heating the cavity for cooking food; a spring biased hose reel attached to the housing allowing extension of a hose from the hose reel with rotation of the hose reel to unwind the hose in a first direction against a spring biasing and allowing retraction of the hose with rotation winding of the hose about the hose reel in a second opposite direction with the spring biasing; an electronic water valve receiving water from a source of pressurized water and communicating it to the hose on the hose reel when the electronic water valve is opened with a valve open signal; and a hose reel sensor sensing a first state of the hose reel when the hose is fully retracted and a second state of the hose reel when the hose is fully extended to provide the valve open signal in the second state and not the first state.
