WV,

It could be a crack in the defrost drain pan, if you've moved the fridge recently,

You should remove the front kick plate / grille from the bottom of the front of the fridge, and look for water in the drain pan.

Most likely what you would check for and find , is a loose connection on the water dispenser fill tube double connector behind the grille and clipped up to the base frame of the freezer compartment.

Also check the fill tube where it comes out at the bottom of the door.

Good Luck,
:) :) :)
