Water Leaking Into Fridge

Ice accumulates under the bottom panel of the freezer.
This is causing water to drip down into the fridge.

It was defrosted and it happened again in 2 weeks.
The drain hole is not clogged.
(except for the ice)
The freezer is not set too cold.

I wish the solution was that easy.:frowning:

I would imagine that this one is going to co$t me.
Any ideas?
Thanks.
