A washing machine appliance includes a water supply configured to selectively dispense wash fluid into a wash tub, a bulk dispenser for selectively adding a wash additive to the wash fluid, and a conductivity sensor for measuring an electrical conductivity of the wash fluid collected in the wash tub. A controller is configured to obtain a first additive conductivity metric of the wash additive stored within the bulk dispenser using the conductivity sensor, determine that the bulk dispenser has been refilled, obtain a second additive conductivity metric of the wash additive stored within the bulk dispenser using the conductivity sensor, determine that the second additive conductivity metric is different than the first additive conductivity metric, and implement a responsive action in response to determining that the second additive conductivity metric is different than the first additive conductivity metric.

Systems and methods for automatic dispensing of wash additives in a washing machine appliance

An appliance, system, and method for operating an appliance and determining presence of water softener at water provided to an appliance is provided. The system is configured to obtain a first water hardness value; obtain a second water hardness value based on a location of the appliance; determine a ratio of the first water hardness value and the second water hardness value; compare the ratio of the first water hardness value and the second water hardness value to a threshold limit; transmit a first water hardness signal when the threshold limit is exceeded, wherein the first water hardness signal corresponds to the first water hardness value; transmit, to the database storage device, a second water hardness signal when the ratio is within the threshold limit; and adjust operation of the appliance based on whether the first water hardness signal or the second water hardness signal is transmitted.

System and method for determining presence of water softener

A washing machine appliance may include a wash tub, a wash basket, a dispensing assembly, a water hardness sensor, a camera assembly, and a controller. The wash tub may be positioned within a cabinet. The water hardness sensor may be mounted in fluid communication with the wash tub. The camera assembly may be spaced apart from the wash tub. The controller may be communicatively coupled to the water hardness sensor and the camera assembly. The controller may be configured to direct a washing operation. The washing operation may include identifying a wash additive provided to the washing machine appliance, determining a water hardness level of water provided to the washing machine appliance, determining a cycle additive volume based on the identified wash additive and the determined water hardness level, and dispensing the determined cycle additive volume within the wash tub.
