  • Publication number: 20260049426
    Abstract: An interconnected system of appliances and method for operation include a first and second appliance fluidly coupled together by a water supply valve. The first appliance obtains a fault condition signal of the first appliance and obtains an operating condition signal of the second appliance. The operating condition signal is compared to the fault condition signal. A first communication signal is generated to determine an operational state at the water supply valve when the compared operating condition signal corresponds to the fault condition signal. A second communication signal is generated indicating a fault condition of the plurality of appliances when the determined operational state corresponds to an open valve state. The first appliance transmits the second communication signal to the second appliance. A third communication signal is generated corresponding to a fault condition when comparing the operating condition signal does not correspond together the fault condition signals.

  • Patent number: 12344982
    Abstract: A laundry appliance includes a drum rotatably mounted within a cabinet and defining a chamber configured for receiving a load of clothes, a door pivotally mounted to the cabinet for providing selective access to the chamber, and a user interface for controlling operation of the laundry appliance. A controller is configured to monitor the number of wash cycles that have occurred in the laundry appliance since the last self-clean cycle. Once the laundry appliance reaches a predetermined number of wash cycles without an intervening self-clean cycle, an automatic self-clean cycle is initiated upon the next selection of a drying cycle by the user, wherein the drying cycle provides an indication that the chamber is empty of article of laundry and that the user has no further immediate washing needs. In these circumstances, the controller is configured to reconfigure the selected drying cycle into a combination cycle including a self-clean cycle which is automatically followed by the desired drying cycle.
