Samsung accumulating water under drawers

I have a Samsung bottom freezer unit and suddenly have an accumulation of water and ice under the bottom refrigerator drawer.

There is no water being supplied to this unit.

Any ideas?

Mine is doing the same thing. Told it is a clogged drain line. Probably frozen and needs to be cleaned or defrosted. Having issues with getting it covered under extended warranty, but hopefully resolved as NOT a maintance issue. Tec said it may be caused by too narrow of a drain line and it will reoccur. Also, ther is a fix I read about online but it is for the folks who like to fix things. Hope this helps and good luck.
