  • Patent number: 10465324
    Abstract: A washing machine appliance includes a wash tub defining a wash chamber for receipt of a load of articles for washing and a water control valve for regulating a flow of water from a water supply into the wash chamber. A controller is configured for detecting a low water level in the wash chamber, e.g., due to a low water supply pressure, by obtaining a target volume and a fill volume; obtaining an underfill limit based at least in part on the fill volume; obtaining a tub water level after attempting to fill to the target volume; obtaining a new fill level if the tub water level is less than the underfill limit; and filling the wash tub to the new fill level.

  • Publication number: 20190257018
    Abstract: A washing machine appliance includes a motor for selectively rotating a wash basket within a wash tub. A controller is configured for initiating a spin cycle by ramping up the speed of the wash basket to a target speed. The controller monitors a measured basket speed to determine whether the measured basket speed has reached a predetermined acceleration reference speed within an acceleration time limit or whether the measured basket speed has fallen below a dropout reference speed for a dropout time limit. If either condition exists, the controller adjusts the operation of the washing machine appliance, e.g., by reducing the wash basket speed to permit wash fluid entrained in the annulus to escape and reduce drag on the wash basket.

  • Patent number: 9765464
    Abstract: A method for washing articles in a wash chamber of the washing machine appliance is provided. The method includes receiving user input of a user-selected water fill amount for a wash cycle, the user-selected water fill amount being the largest water fill amount available for selection by a user. The method also includes determining a characteristic of a load of the washing machine appliance and determining that an amount of water associated with the user-selected water fill amount is inadequate for the load. In response, the method includes providing the wash chamber of the washing machine appliance with an amount of water greater than an amount associated with the user-selected water fill amount.

  • Publication number: 20170073877
    Abstract: A washing machine and a method for operating a washing machine appliance. After the user selects a wash cycle, the washing machine appliance may perform a load sensing routine, during which a standard water fill amount and standard agitation intensity are determined. The washing machine appliance includes a controller that receives a user input of a supplemental water fill amount and provides the tub with an amount of water equal to the standard water fill amount plus the supplemental water fill amount. The controller determines an increased agitation intensity based at least in part on the supplemental water fill amount and operates the motor in order to rotate an agitation element according to the increased agitation intensity. The present subject matter thereby enables a user to adjust the water fill amount while maintaining the agitation stroke intensity.

  • Patent number: 9109321
    Abstract: An appliance for washing objects that employs a spray device for delivering a washing fluid, e.g., water, to a wash tub in the appliance. The spray device is configured to reduce consumption of the washing fluid such as during a rinse portion of a washing cycle. In one example, the spray device comprises a plurality of apertures that are arranged in one or more arrays. The apertures are configured to disperse the washing fluid as a plurality of spray streams that form a pair of wetted areas on either side the wash tub. The wetted areas provide wetting of the objects along the sides and extending from a front portion to a back portion of the wash tub.
