Heater Block - Corrosion? melted? IDK
I recently assembled my Original Prusa i3 MK3S+ 3D printer Kit about two weeks ago and its been printing great so far. Just yesterday I tried setting up a new print and I started seeing and smelling smoke coming out of the extruder. I noticed that when I was loading the new material for the print I was setting up, it started oozing out the threads of the nozzle. When I tried to change the nozzle it actually broke in half in the heater block (it took almost no effort to break in half). This is when I noticed that the heater block was completely deformed and warped. The LCD screen didn't give me any kind of error like over heating or MAXTEMP so I don't believe the printer was "aware" of what was happening to it.
Has anyone ever encountered something like this? I know I can change out the hotend end or the heater block, but I'd like to know what caused this so I can avoid it in the future. Any insight on this would be very much appreciated.

Since it's a new printer, I would contact Prusa support.
If you want to fix it yourself, you will most likely have to disassemble the hot end, remove the remains of the nozzle, clean it up, and re-assemble and re-calibrate.
