Water dispenser works..No water going into ice tray...I have haired tried the black rubber spout...I want to remove the plastic tube that carries water to the ice tray at the rear bottom of the fridge to the top of the fridge...There must be some secret on removing the plastic tube at the bottom so I may be able to blow any obstruction in the line going from the water inlet to the ice maker....Any expert opinions on how to release the water plastic tube?....George Campbell Stuart,Fl
