Throughout the wash cycle, it accurately controls the timing and operation of these components to achieve the best cleaning results.Consider the control board to be an orchestra conductor, commanding each dishwashing component to perform its function at the appropriate timing and intensity. A defective control board can upset this balance, resulting in failures like as incomplete wash cycles, improper water temperature during the wash, and unresponsive buttons on the user interface.
