A method of opening a door of a household appliance having a cabinet with an open face providing access to a treating chamber where an article is received for treatment according to a useful cycle of operation is provided. The method includes: sensing a presence of at least a portion of a person within a predetermined range of the door and out of contact with the door; and automatically opening the door in response to the sensed presence.

A dishwasher appliance includes a door pivotally providing selective access to the wash chamber and a venting system comprising a first fan for urging chamber air from the wash chamber and a second fan for urging ambient air, wherein the chamber air and the ambient air mix to create a mixed flow of air that is discharged from the dishwasher appliance. A controller is configured to energize the first fan and the second fan, monitor a power draw by the first fan and the second fan, determine that the venting system has malfunctioned based at least in part on the power draw by the first fan and the second fan, and implement a responsive action in response to determining that the venting system has malfunctioned based at least in part on the power draw.

An appliance and method for determining an operational state of the appliance is provided. The appliance includes a cabinet, a flow device, and a sensor positioned at the cabinet. The cabinet includes a plurality of panels forming an interior volume at which a wash chamber is positioned. The flow device is configured to flow a fluid at the wash chamber. The sensor is positioned at the cabinet and configured to obtain sound vibrations from the wash chamber. The method includes obtaining, from the sensor, a signal during flow of a fluid at the wash chamber, and comparing the signal to a predetermined operational profile corresponding to operation of the flow device at the wash chamber to determine whether the flow device is operating properly.

A dishwasher and a controlling method thereof are provided. The dishwasher according to an embodiment includes a display, a user interface, memory storing at least one instruction, and one or more processors configured to execute the at least one instruction, and the one or more processors are configured to, based on the dishwasher being turned on, control the display to display a first GUI corresponding to at least one dishwashing course, based on a user input for selecting a dishwashing course being received through the user interface, control the display to display a second GUI including an animation effect that indicates dish loading information corresponding to the selected dishwashing course, based on a dishwashing operation being started based on the selected dishwashing course, control the display to display a third GUI indicating the dishwashing course and dishwashing time.

A dish washer is configured to recognize when a user intends to open a door while a washing course in a tub is in progress. The dish washer includes a handle driver, a controller, and a handle configured to protrude in a frontward direction when the washing process has been stopped, thereby securing convenience and safety.

A dishwasher appliance includes a wash tub and a sump for collecting wash fluid, a pump assembly for selectively urging a flow of the wash fluid from the sump, a pressure sensor for monitoring a wash fluid level within the wash tub, a microphone for monitoring sound generated during operation of the dishwasher appliance, and a controller configured to obtain a pressure reading using the pressure sensor, determine that the wash fluid in the sump is at a low level based at least in part on the pressure reading, energize the pump assembly to circulate the wash fluid, obtain a sound signal generated during energization of the pump assembly using the microphone, determine that the wash fluid in the sump is not at a low level based at least in part on the sound signal, and provide a user notification that the pressure sensor is defective.

A method for operating a water-bearing household appliance for treating articles, in particular a dishwasher or washing machine, the water-bearing household appliance including a treatment chamber for treating the articles with a washing liquor and a dosing system for dispensing a dosing-amount of detergent provided by a dosing unit, the method comprising: selecting one of a plurality of different treatment cycles, controlling the water-bearing household appliance to perform the selected treatment cycle, actuating the dosing system to dispense the dosing-amount of detergent according to the selected treatment cycle, detecting a sensor signal of the dispensed dosing-amount of detergent, adjusting the selected treatment cycle as a function of the detected sensor signal, and controlling the water-bearing household appliance to perform the adjusted treatment cycle.

A dishwasher appliance includes a door pivotally providing selective access to the wash chamber and a venting system comprising a first fan for urging chamber air from the wash chamber and a second fan for urging ambient air, wherein the chamber air and the ambient air mix to create a mixed flow of air that is discharged from the dishwasher appliance. A controller is configured to energize the first fan and the second fan, monitor a power draw by the first fan and the second fan, determine that the venting system has malfunctioned based at least in part on the power draw by the first fan and the second fan, and implement a responsive action in response to determining that the venting system has malfunctioned based at least in part on the power draw.
