Dishwashing appliances and fluid-loss mitigation

A wash 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 fluid pump in fluid communication with the wash chamber, the fluid pump being a drain pump mounted within the cabinet downstream from the wash chamber;
• a controller in operative communication with the fluid pump and 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 wash 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 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, the mitigation action comprising directing the controller to the active operational mode from the standby mode.
