A washing machine appliance includes a wash basket that is rotatably mounted within a wash tub and that defines a wash chamber for receiving a load of clothes. A water supply selectively dispenses a flow of wash fluid and a bulk dispenser selectively adds a wash additive to the flow of wash fluid. A controller is configured to initiate a bulk flush operation by operating the water supply to provide the flow of wash fluid and the bulk dispenser to dispense the wash additive, obtain one or more images of the flow of wash fluid using a camera assembly, analyze the one or more images using an image recognition process to determine an additive content of the flow of wash fluid, and terminate the bulk flush operation in response to determining that the additive content falls below a predetermined additive threshold.

Systems and methods for using artificial intelligence to perform a bulk flush process 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 pump is configured to drain liquid from the wash basket. A vent line extends between the wash basket and the cabinet. The vent line includes a fan, a humidity sensor proximate the fan, and a controller. The controller is operable to perform a drain cycle. The drain cycle includes activating the pump. Comparing, across a set interval of time, a humidity within the washing machine appliance to a reference humidity. Determining the humidity's proximity to the reference humidity. Detecting a fault in the drain cycle in response to the humidity exceeding the reference humidity. Continuing a rinse cycle in response to the humidity being proximate the reference humidity.

Systems and methods for drain pump and humidity sensor operation verification

A method of operating a washing machine appliance includes measuring a humidity value with the humidity sensor and comparing the measured humidity value to an expected humidity value. The method also includes flagging a fault in response to the measured humidity value differing from the expected humidity value by at least a predetermined threshold.
