I experienced this problem before but it was over 5 years ago. So I went online to your site and determined it was the water filter head housing assembly that needed to be replaced. I watched the video on how to replace the part and found it to be very helpful. I ordered the part from Appliance Parts Pros which I received very quickly. Then I replaced the water filter head as per your instructional video and fixed the problem. I am 81 years old and this fix was relatively easy for me.
