The coupler that connects the water lines to the water filter was leaking at connection. Originally believed it was the water filter gasket but after replacing with a new filter it continued to leak. The repair is very easy but takes time to disassemble the housing the contains the coupler. The crisper drawers and shelf unit needs to be removed to access the vertical shelf brace housing. You will need to remove the front vanity piece then split the housing apart. There are two screws in addition to several clips on the top and bottom of the housing. There is also two screws that the housing secures to the back wall and a hidden clip. From there it is simple, just split the housing and replace the part. I only needed the coupler but was only available with the hoses.
