Abstract
Example methods for determining an over-sudsing condition during a wash cycle of operation in a laundry treating appliance containing a foamable liquid are disclosed. An example method includes rotating within a tub a drum defining a treating chamber while the tub contains a foamable liquid, determining, over time, a fluctuation in a signal from a pressure sensor fluidly coupled to the tub while the drum is rotating, the signal representing an amount of water in the tub, determining an over-sudsing condition when the fluctuation satisfies a predetermined threshold, and altering a cycle of operation in response to the determination of an over-sudsing condition.
