After searching the WEB on how to remove the filter, I came across several methods given for the model I had. As it turned out, the method that said: Push the button beside the filter with some effort to "pop it out". That method worked. Replaced the filter and ran the water dispenser until all the air was purged from the line. Pressed the RESET button in the refrigerator and the filter light went to green. The following evaluation for time taken on the repair is for my initial attempt. Now it will be less than 15 min. and an easy replacement.
