A washing machine appliance includes a wash tub positioned within a cabinet, a wash basket rotatably mounted within the wash tub, a blower operably coupled to the wash basket, a motor assembly mechanically coupled to the wash basket for rotating the wash basket, and a controller. The blower is configured to introduce air into the wash basket. The controller is configured to initiate a wash cycle for cleaning the load of clothes, determine that air dry conditions are satisfied, and perform an air dry operation after completion of the wash cycle in response to determining that the air dry conditions are satisfied. The air dry operation may include operating the blower to circulate the air within the wash basket and operating the motor assembly to tumble the load of clothes. A method of operating a washing machine appliance is also provided.

A laundry appliance includes a drum rotatably mounted within a cabinet and defining a chamber configured for receiving a load of clothes, a door pivotally mounted to the cabinet for providing selective access to the chamber, and a user interface for controlling operation of the laundry appliance. A controller is configured to monitor the number of wash cycles that have occurred in the laundry appliance since the last self-clean cycle. Once the laundry appliance reaches a predetermined number of wash cycles without an intervening self-clean cycle, an automatic self-clean cycle is initiated upon the next selection of a drying cycle by the user, wherein the drying cycle provides an indication that the chamber is empty of article of laundry and that the user has no further immediate washing needs. In these circumstances, the controller is configured to reconfigure the selected drying cycle into a combination cycle including a self-clean cycle which is automatically followed by the desired drying cycle.
