I would think that the water is coming from the defrost cycle.
The drain is located behind the panel at the back of the freezer.
The drain is likely plugged up.
Remove the back panel and clear the drain.
You may want to run a stiff but flexible piece of wire down through to make sure you get every thing.
Let the freezer get cold again and then turn the ice maker back on.
I think this should cure your problem.
