Low Power Management System

A method of managing appliance power consumption, the method comprising:

• monitoring, by one or more low power management microcontrollers, a state of each of a plurality of system microcontrollers associated with an appliance;
• determining, by the one or more low power management microcontrollers, that one or more of the plurality of system microcontrollers are in an inactive state;
• and
• sending, by the one or more low power management microcontrollers, one or more command signals to place the one or more system microcontrollers in the inactive state in a lower power mode based at least in part on the determination that the one or more system microcontrollers is in the inactive state, wherein the lower power mode is associated with a reduced power consumption by the respective microcontroller than while in an active state.

A dishwashing appliance, comprising:

• a first system microcontroller associated with a user interface;
• a second system microcontroller associated with one or more relays;
• a third system microcontroller associated with a drain pump assembly;
• and
• one or more low power management microcontrollers configured to:
• monitor one or more communications associated with at least one of the first system microcontroller, second system microcontroller, or third system microcontroller, wherein the one or more communications are indicative of a state of least one of the first system microcontroller, second system microcontroller, or third system microcontroller;
• determine that at least one of the first system microcontroller, second system microcontroller, or third system microcontroller is in an inactive state based at least in part on the one or more communications;
• and
• place the at least one system microcontroller in the inactive state in the lower power mode based at least in part on the determination that the respective system microcontroller is in the inactive state, wherein the respective system microcontroller consumes less power in the lower power mode than while in an active state.
