switch off fridge freezer. remove drawers from freezer.remove panel at back of compartment, four screws,one at each corner. behind this panel you will find the cooling coils and circulating fan,etc. at the bottom of the compartment there is a drainage channel,at the centre of this drainage channel a hole should drain the water off when freezer defrosts, but every so often this hole gets covered over with ice and water runs out through the bottom of the freezer door, clear the ice, reassemble, should be ok till next time.
