Dish treating appliance with leak detection

A diverter valve assembly comprising:

• a housing defining an interior with a liquid leak reservoir;
• a motor carried by the housing;
• an output shaft rotationally driven by the motor and extending through the housing;
• a printed circuit board (PCB) located within the housing and out of the liquid leak reservoir and having a liquid detection circuit comprising at least two traces extending into the liquid leak reservoir;
• and
• a diverter valve having a rotatable valve body mounted to the output shaft;
• wherein liquid running along the output shaft can enter the housing and flow along the liquid leak reservoir to short the two traces and provide an input to the liquid detection circuit.

A dish treating appliance for treating dishes according to an automatic cycle of operation, the dish treating appliance comprising:

• a tub having a lower wall including a sump and at least partially defining a treating chamber receiving dishes for treatment according to the automatic cycle of operation;
• a controller configured to control the operation of the dish treating appliance to complete the automatic cycle of operation;
• at least one sprayer emitting a liquid into the treating chamber;
• a recirculation pump supplying liquid to the at least one sprayer;
• a diverter valve operably coupled with the controller and located within the treating chamber above the lower wall and having a rotatable valve body selectively fluidly coupling the at least one sprayer with the recirculation pump;
• and
• a rotary drive located below the lower wall, exteriorly of the tub, and comprising:
• a housing defining an interior with a liquid leak reservoir;
• a motor carried by the housing;
• an output shaft rotationally driven by the motor, extending through the housing and the lower wall of the tub, and operably coupled to the valve body;
• and
• a printed circuit board (PCB) operably coupled with the controller and located within the housing and out of the liquid leak reservoir and having a liquid detection circuit comprising at least two traces extending into the liquid leak reservoir, the PCB configured to operate under normal operation with no liquid present in the liquid leak reservoir;
• wherein liquid leaking from the tub and running along the output shaft can enter the housing and flow along the liquid leak reservoir to short the two traces and provide an input to the liquid detection circuit of the PCB to cause the controller to send a signal to disable the diverter valve.
