I cleared mine out, all happy, and 3 months later it clogged back again. I don't bother fixing it because I need to remove all the contents of the fridge, then dissassemble the inside rear of the fridge to get access to the right spot. It's just a bad design.
Terrible design. Won't be buying Samsung again.
What an awful fridge.
Try running through the process and double the duration of every step, and don't skip any steps, and it should stop leaking.
Alternatively throw the damn thing in the garbage.
For mine I had to flush it with a syringe of warm water to thaw out the drain port. The hard part is getting to the drain hole. Also, the fix lasted 6 months or so before it iced over again. I'm out of warranty so I might just run a much larger line and call it a day.
If your lucky your issue might just be a blockage, which should clear easily.
