Abstract
A washing machine appliance and methods of operating a washing machine appliance are provided. The washing machine appliance includes a tub and a rotatable basket within the tub. A volume of water is flows into the tub, causing a load of articles in the basket to be wetted. A first weight of the load of articles is measured during an initial spin operation after flowing the volume of water into the wash tub. A water extraction operation is performed after measuring the first weight of the load of articles. A second weight of the load of articles is measured after the water extraction operation. A load type of the load of articles is determined based on the first weight and the second weight.
