A washing machine appliance includes a cabinet, and a wash tub mounted within the cabinet. The washing machine appliance further includes a wash basket rotatably mounted within the wash tub. A method includes commencing an operating cycle, and sending, during the operating cycle, an activation command to a drain pump of the washing machine appliance. The method also includes obtaining one or more images of the wash tub, after sending the activation command, using a camera mounted within the cabinet. The method further includes analyzing the one or more images of the wash tub, and determining whether the drain pump is operating as expected based at least in part on the analysis of the one or more images. The drain pump operating as expected includes draining wash liquid from the wash tub at or above a minimum drain rate.
