daewoo fridge freezer broken waterline

I wonder if someone can help me please. I have a Daewoo fridge freezer American style model FRS2031IAL with a broken waterline at the bottom of the freezer door. I have a new waterline but cannot get access to the broken waterline in the door. I have removed the display unit on the front but the plastic panel behind it seems to be glued to the door. I can see the rubber spout but not the waterline that it is connected to. Anyone has any idea how this can be done please? Your assistance would be very much appreciated. Thanks.

Doesn't look like anyone has come across this problem yet but if you do please reply. Thanks.
