Water leaking under the refrigerator only when water was called from water dispenser

To do this repair, I shut off the water supply first. After removing the back panel, I disconnected the first water tank (PS291933) tube from the valve near the back of the refrigerator by pushing the white ringclamp towards the valve which released the tubing (once disconnected I could clearly see the hairline crack in the tube responsible for the water). I then disconnected the other water tank tube from the connector located in the bottom left front of the refrigerator. Then, after removing the bottom shelves and compartments, I unscrewed the two screws securing the water tank to the inside back wall. Then I carefully pulled the water tank and the tubing out from inside the refrigerator. The installation of the new water tank was essentially the reverse of the above, with the exception that I had to use a 2x4 to prop up the refrigerator and my 7-year old daughter's hand to help guide the tube to the front of the fridge. One of the lines did leak initially, but stopped after I removed and reconnected the tube more securely. My only unfinished business with this part of the repair (which I'm not losing sleep over) is I'm not sure where to find the 'insulation wrap' that was around the water tank tubes inside the fridge.

During my investigation of the water tank, I also noticed the tube on the outside back of the fridge going to the icemaker was leaking, so I bought a new grommet & tube (PS292253). Installation was easier than the water tank, but was more of a mystery until the part showed up and I saw that only adhesive tape was used to secure the grommet to the hole in the outside back of the freezer near the icemaker. Again, only had to disconnect the tube from the valve at the bottom of the fridge and pull out the grommet from the top outside. (I did remove the ice cube tray from the inside to avoid contaminating it during the work). Then I connected the new tubing and secured the grommet to the back of the fridge using the adhesive tape. So far no leaks!


I also will likely need to add that WR49X10173 part to hopefully avoid my water dispensor from freezing in the future.
