How often should the water filter be replaced, and how do I reset the filter status light?

The water filter should be replaced at least every 6 months, depending on your water quality and usage, or sooner if water flow decreases noticeably. To reset the filter status light, the method depends on your model — for example, press and hold the Filter button for 3 seconds, or press and hold the Light and Ice Type buttons simultaneously for 3 seconds. The replacement filter part number is W10295370A (P4Rfwb). (Page 16)
