Customer Questions and Answers for Plug by Whirlpool

Linda, No, you won't need a "bypass plug" for your refrigerator " NOTE: You can run the dispenser without a filter. Your water will not be filtered. Simply insert the cap all of the way into the base grille and rotate the cap until it is firmly in place." However, you will have to reset the "change filter" system, occasionally, depending on water and ice usage.
