A:AnswerThere isn't a water line. At the front of the machine there is a water tray you fill. I love my dryer! I've had it for about a month. I hope that helps.
A:AnswerWater is Only needed for the Steam settings. With the WT7800CV model, you need to add TAP WATER to the tray each time the steam fresh or sanitary options are used. LG also has a model that is directly hooked up to your water line and requires a "steam kit"; so that model does not require water in the tray.
