Abstract: A washing machine appliance includes a tub and a rotatable basket therein. Methods of operating the washing machine appliance may include, and/or the washing machine appliance may be configured for, measuring a first inertia of a load of articles in the basket by rotating the basket at rotational speeds outside of a resonance speed zone.

Abstract: A washing machine appliance includes a sump for collecting wash fluid, a water supply valve for supplying the wash fluid during a fill cycle, and a water level detection system including a pressure sensor for measuring sump pressures/fill levels. A controller is configured for operating the supply valve to fill the sump until a target volume is reached and obtaining a fill volume using the water level detection system. The controller determines that a fault condition exists based on a difference between the target volume and the fill volume, e.g., such as when the difference exceeds a predetermined fault threshold, and initiates a fault abatement process in response to determining that the fault condition exists.

Abstract: A washing machine appliance includes a sump for collecting wash fluid, a supply valve for supplying the wash fluid, a drain assembly for discharging the wash fluid from the sump, and a water level detection system for measuring sump pressures/fill levels. A controller is configured to perform an initial fill cycle and determine a first volume of wash fluid required to reach a target pressure. The drain assembly then drains the sump and the process is repeated to determine a second volume of wash fluid required to reach the target pressure. The difference between the first volume and the second volume is at least partially a result of wash fluid that the drain assembly could not discharge through the drain hose. The controller may determine that the external drain is elevated, and compensate accordingly, if a difference between the first volume and the second volume exceeds a predetermined threshold.
