How to Troubleshoot & Replace Whirlpool AP6005564 / WP12777701 Filter Block (Foam), 1 Piece

Replaced the water filter head. Watched the youtube video made by Appliance Parts Pros. Luckily I bought the two related parts (the styrofoam block fill and the backing plate) because I broke both in removing the old part. All the parts together were about the same cost as a filter so it really paid off 

Was a pretty easy job with the help of your tutorial. Job was done in thirty minutes. 

First replaced water/ice maker solenoid switches at bottom of refrigerator with no improvement. Then replaced filter head and the base that was broken. That fixed the problem as the filter head had started leaking when cap/filter was removed. There was no leak for a long time at the filter head so it was difficult to determine just where the problem was in the system.
