Abstract
A washing machine appliance has a drum positioned within a tub. The drum defines a wash chamber for receipt of articles for washing and sanitizing. A method of operating the washing machine appliance includes, in a rinse cycle, filling the tub with a cold water rinse volume to a predetermined fill level, adding a volume of sanitizing additive to the tub, and performing an agitation cycle for a predetermined time period. The first cold water rinse volume and the sanitizing additive are mixed during the first agitation cycle to form a sanitizing liquor. The rinse cycle further includes draining the sanitizing liquor from the tub after performing the agitation cycle and performing an extraction cycle after draining the sanitizing liquor from the tub. As a result, the washing machine appliance and articles therein are sanitized.
