Abstract
A method for operating a washing machine appliance, the washing machine appliance including a wash tub positioned within a cabinet, a dispensing assembly for selectively adding wash fluid to the wash tub, a conductivity sensor and a turbidity sensor positioned within the wash fluid, the method including initiating an operating cycle of the washing machine appliance, operating the dispensing assembly to dispense wash fluid into the wash tub, obtaining an electrical conductivity of the wash fluid using the conductivity sensor, obtaining a wash fluid turbidity of the wash fluid using the turbidity sensor, identifying a wash additive within the wash fluid based at least in part on the electrical conductivity and the wash fluid turbidity of the wash fluid, and implementing a responsive action in response to determining that a wash additive does not match the target wash additive.
