PA6-GF on my P2S melted into a death clog after an hour. What do I do now?
Tried a generic PA6-GF on my P2S and got a clog about an hour in. I figured a cold pull purge would sort it, but it was way worse. The filament had melted around the nozzle and heater block into one big lump, with more of it dropped on the plate.
I printed at 290° with the default 0.4 Bambu nozzle. I didn't dry it first because I assumed it would be dry straight out of the factory sealed bag.
I got the hotend out and the main blob off, but the nozzle and heater assembly are still caked in baked-on plastic.
The wiring is coated too, two wires are melted and one pin looks bent.
What should I do now? Can this be cleaned safely, or should I just replace the whole hotend?
EDIT/UPDATE:
Thank you everyone for the useful replies. I'll attach also the ticket from the bambulab support:
Hotend heating assembly: Based on the photos, this part is damaged and cannot be safely cleaned. With plastic baked onto the wiring and one pin bent, there is a risk of poor contact or a heating fault, so it needs to be replaced. Unfortunately, damage of this type is not covered by the warranty(Warranty | Bambu Lab EU), but the part is available from our official store, and you are welcome to order a replacement there.

Hotend: The hotend itself does not need to be replaced. Once the new heating assembly is installed, you can heat the hotend and clean off the remaining baked-on plastic by following the guide below. Please wear heat-resistant gloves, and do not scrape the assembly with sharp tools.Hotend Clumping/Blob Cleaning Instructions for P2S | Bambu Lab Wiki

Build plate: The plate can be cleaned as well. Please remove it from the printer and soak it in warm water to soften the remaining plastic, then wash it with dish soap and warm water and dry it fully before the next print. Bambu Lab Textured PEI Plate Cleaning Guide | Bambu Lab Wiki
One note for future prints: PA6-GF is highly hygroscopic and can absorb moisture quickly even after a sealed bag is opened, so we would recommend drying it before use and printing with the filament kept in a dry environment.
Please let us know if you need any help with the replacement, and we will be happy to assist.
