Abstract
A method for operating a washing machine appliance includes initiating a rinse cycle of the washing machine appliance, operating a dispensing assembly to dispense wash fluid into the wash tub, obtaining a wash fluid turbidity of the wash fluid using the turbidity sensor, determining that a target volume of wash additive was added to the wash fluid based at least in part on the wash fluid turbidity, and implementing a responsive action in response to determining that the target volume of the wash additive was added to the wash fluid.

A method for operating a washing machine appliance, the washing machine appliance comprising a wash tub positioned within a cabinet, a dispensing assembly for selectively adding wash fluid to the wash tub, and a turbidity sensor positioned within the wash fluid, the method comprising:
- initiating a rinse cycle of the washing machine appliance;
- operating a dispensing assembly to dispense wash fluid into the wash tub;
- obtaining a wash fluid turbidity of the wash fluid using the turbidity sensor;
- determining a volume of wash additive was added to the wash fluid based at least in part on the wash fluid turbidity;
- and
- implementing a responsive action in response to determining the volume of the wash additive was added to the wash fluid.
A washing machine appliance, comprising:
- a wash tub positioned within a cabinet;
- a wash basket rotatably mounted within the wash tub and defining a wash chamber configured for receiving a load of clothes;
- a dispensing assembly for selectively adding wash fluid to the wash tub, the wash fluid comprising at least one of water or wash additive;
- a sump positioned proximate a bottom of the wash tub for collecting the wash fluid;
- a turbidity sensor positioned within the wash fluid;
- and
- a controller operably coupled to the dispensing assembly, the controller being configured to:
- initiate a rinse cycle of the washing machine appliance;
- operate the dispensing assembly to dispense the wash fluid into the wash tub;
- obtain a wash fluid turbidity of the wash fluid using the turbidity sensor;
- determine a target volume of wash additive was added to the wash fluid based at least in part on the wash fluid turbidity;
- and
- implement a responsive action in response to determining the volume of the wash additive was added to the wash fluid.
