Samsung fridge+freezer.
Some time ago, a few weeks - started forming ice at the bottom layer so I had to bash it a bit to break it. Removed the bottom basket and noticed there was ice around the areas with the arrows.

Removed as much as I could and took a hairdryer and melted what I could see.

I suspect the "outflow" tube or whatever it's called - is plugged. Or the inlet for it.
But I cannot access it to see.
What I can see is perhaps some spiral in a shallow pan. Is that a heating element that is supposed to keep the dripping liquid from freezing. Could that be malfunctioning and stopped being warm?

I cannot turn off the freezer section, so I did what I could. It's a hot time of year so its risky to leave the whole thing off for an hour or more.

Any suggestions?
