Abstract: A washing machine appliance including a ventilation structure. A vent line is at a wash tub. A vent filter is provided to the vent line that allows air to flow from the wash tub, and through the vent line, the vent filter redirecting cleaning fluids impinging on the vent filter back toward the wash tub. The vent filter may include a plurality of louvers. The louvers may be located adjacent to one another so as to form a plurality of openings for the flow of air from the wash tub.

Abstract: Washing machine appliances and methods of operating the same are provided. Such methods may include, and/or appliances may be configured for, performing a wash operation on laundry articles received in the wash chamber of the wash basket. After the wash operation, it may be determined that the load of articles is still wet, e.g., that a remaining moisture content of the laundry articles is above a threshold. Based on and in response to determining that the load is still wet, a spin cycle is performed before a beginning of a subsequent wash operation.

Abstract: A method of operating a washing appliance includes obtaining images of a wash chamber using a camera assembly while the wash basket is tumbling a load of clothes positioned therein. The one or more images are analyzed using a machine learning image recognition process to determine a tumble condition of the load of clothes in the wash basket, e.g., whether the clothes are tumbling in the wash basket in a manner that generates suitable mechanical washing action. The motor assembly is then used to adjust a basket speed based at least in part on determining that the tumble condition deviates from a target tumble condition.

Abstract: A washing machine appliance may include a tub, a basket, a valve, a spout, a dispenser, a motor, and a controller. The basket may be rotatably mounted and define a chamber for receipt of articles for washing. The valve may be disposed upstream from the tub. The spout may be directed at the tub downstream from the valve. The dispenser may be upstream from the tub for dispensing detergent into the tub. The motor may be in mechanical communication with the basket. The controller may be configured for controlling the washing machine appliance. The controller may be configured to initiate an oversuds-sensitive operation. The oversuds-sensitive operation may include detecting one or more resultant conditions from one or more previous wash cycles of the washing machine appliance, determining an adjusted operating parameter based on the detected resultant conditions, and directing detergent dispensing according to the adjusted operating parameter.

Abstract: Additive dispensing, as provided herein, may include opening a water supply valve for a first index according to a predetermined fill index and directing a wash additive from an additive dispenser to a water supply conduit during an additive segment. The method may also include blocking the wash additive from the additive dispenser to the water supply conduit during a non-additive segment, detecting a fluid level within a wash tub following the first index, and comparing the detected fluid level to a target fluid level. The method may further include opening the water supply valve for a second index based on comparing the detected fluid level within the wash tub to the target fluid level, directing the wash additive from the additive dispenser to the water supply conduit during an additive segment, and blocking the wash additive from the additive dispenser to the water supply conduit during a non-additive segment.

Abstract: A washing machine appliance includes a wash tub defining a wash chamber and an intake and exhaust duct that are fluidly coupled to the wash chamber. A fan is operably coupled to one of these ducts for urging a flow of air through the wash chamber. A controller is configured for determining that a wash cycle has finished and operating the fan according to a periodic fan schedule, the periodic fan schedule comprising an ON time and an OFF time of the fan, to urge the flow of air through the wash chamber and out the exhaust duct to lower a humidity within the wash chamber and the gasket, e.g., to reduce mold and mildew growth.

Abstract: A washing machine appliance and a method of selectively draining a sump of the washing machine appliance at the start of an operating cycle is provided. The method includes determining that the drain pump assembly has drained wash fluid from the sump, e.g., by checking to see whether an empty sump flag has been set in the controller. In addition, the method includes determining that a water supply valve has not been opened since the wash fluid was drained from the sump and that a sump pressure exceeds a predetermined threshold pressure, e.g., indicating that water is in sump that was not intentionally added by the water supply valve. The drain pump assembly is then operated to perform a drain cycle at the beginning of a subsequent operating cycle.

Abstract: A washing machine appliance includes a sump for collecting wash fluid and a drain pump assembly for selectively draining that wash fluid in response to sump pressures measured by a water level detection system. Specifically, a controller is configured for operating the drain pump assembly to perform a drain cycle and obtaining a sump pressure after the drain cycle. A variable flag is set to a first state if the measured pressure exceeds a predetermined threshold pressure, which indicates that a certain amount of wash fluid is present in the sump. During a subsequent operating cycle, the drain pump assembly will be operated at the start of the cycle only if the variable flag was set to the first state during the prior operating cycle.

Abstract: A washing machine appliance, including methods of operation therefor, are provided herein. The washing machine appliance may include a cabinet, a tub positioned within the cabinet, a wash basket, a ventilation line, and a vent damper. The wash basket may be rotatably mounted within the tub. The wash basket may define a wash chamber for receiving articles for washing. The ventilation line may define an air path from the tub to an ambient environment outside of the cabinet. The vent damper may be positioned along ventilation line in fluid communication therewith. The vent damper may be selectively movable between a first position restricting airflow through the ventilation line and a second position permitting airflow through the ventilation line.
