The Whirlpool 12001930 is an indispensable part in your Whirlpool washer, specifically functioning as the dispenser valve assembly. This assembly is critical to maintaining an efficient and effective washing process since it accurately controls the delivery of detergent, bleach, and softener to the washer tub at specific intervals during the wash cycle.Consider the dispenser valve assembly to be a conductor in a symphony; it gets signals from the washer's control board, which operates similarly. These signals instruct the assembly to open specified valves that are attached to predefined detergent or additive inlets. Each valve works like a soloist in an orchestra, releasing a precise amount of detergent, bleach, or softener at the ideal time.
