1. A dishwashing appliance, comprising:
a cabinet;
a tub positioned within the cabinet and defining a wash chamber for receipt of articles for washing;
a door mounted to the cabinet to selectively restrict access to the tub;
a spray assembly positioned within the wash chamber;
a fluid pump in fluid communication with the wash chamber;
a controller configured to alternate between an active operational mode and a standby mode in which a power draw at the controller is less than a power draw of the active operational mode;
a low-power input sensor configured to detect a fluid-loss event at the dishwashing appliance at the standby mode of the controller and transmit a fluid-loss signal in response to detecting the fluid-loss event; and
a conditioning circuit attached to the cabinet in electrical communication with the low-power input sensor and separate from the controller, the conditioning circuit being configured to receive the fluid-loss signal apart from the controller at the standby mode and initiate a mitigation action in response to receiving the fluid-loss signal.
