Have changed water filter, but indicatot panel calls for order h2o filter, and comes on every time we dispence water. why?

Most models also have a filter indicator reset button located in the same area. After changing the filter, reset the filter status light by pressing the Filter Indicator Reset button or by pressing and holding the Filter button for 3 seconds. The status light will change from red to green or the status display will change from "Replace" to "Good" when the system is reset.

If your model has a water filter indicator, but no reset button, press the light switch in the refrigerator compartment 5 times within 10 seconds to reset the system. The status light will change from red to green when the system is reset.
