Can't load any filament
I was printing a 2 color piece and on a color change, the printer throw the usual mmu load failed, but this time the issue was on the extruder.
I can't load any filament. From top I can insert 10cm of filament but don't get melted. I can insert completely the acupuncture needle from below without issue. And as prusa recommended, I checked the PTFE tube and looks perfect (I've no replacement left).
What can I do? Any suggestions?

The needle don't reach the filament from above. There is a small gap of about 2mm.

Finally I've found the clog: A multicolor piece of filament stuck on the heatsink.
