Abstract

Inferring the laundry cycle type for a load of laundry items is provided. Measurements are performed of a laundry load in a drum of a laundry appliance during a pre-rinse cycle, the measurements including one or more of an absorption ratio of the laundry load, a retention ratio of the laundry load, a dry mass of the laundry load, a wet mass of the laundry load, or a spun mass of the laundry load. A model is used to determine load parameters based on the measurements. The load parameters are used to determine a laundry cycle type for the laundry load.
