I am having an issue with my filter head leaking with the filter in and water continues to flow when I remove the filter. I want to replace the filter head but I want to see if it is truly a do it yourself job or if I need a professional. I want to take a look at how to remove the panels to get at the filter head and lines. The filter head itself has a couple of screws that I can get to from the front panel, but I really want to know were those water lines go. I can't find any diagrams or videos of any one repairing a GE 42" built in, any help or direction would be greatly appreciated. Thank you!
