Abstract

A method of operating a washing machine appliance includes flowing a volume of wash liquid into the wash tub. The method also includes activating a heater in thermal communication with the wash tub. As a result of activating the heater, the wash liquid is heated. The method further includes measuring a humidity value with a humidity sensor positioned and configured to measure a humidity within the wash tub and determining, based on the measured humidity value, a steam generation status.
