LG bottom freezer leaking

The ice dispenser on my LG bottom freezer/refrigerator was not working. We took off the bottom back, cleaned the coils, removed and reattached the water tube going into the refrigerator and the water tube coming from the main turnoff. NOW, the dispenser started working, but there is a puddle of water on the floor that was never there before. We checked the connection on the back coming from the main tube into the refrigerator. It was not wet. Could I have dislodged something in the tube going into the fridge that I pulled all the way out and then reinserted? I would appreciate any help you could give. Thank you.
