Clog im troath on A10

[berlinpose2]

I have problem with making filament clog in hotend. What troath is on geeetech a10? I assemble the hotend im this step. I insert the nozzle to the end, then make half turn back, insert the troath with radiator, make 200 C and turn nozzle max. But when i start. Printing on few minutes i get extruder to tick and when i disassemble hotend i see not meltedv filament down in troath near nozzle. I think the ptfe tube goes to end od troath and is cut correct.

Hi, maybe the nozzle or hot end is blocked, it is recommended to clean them. The ptfe tube should be inserted at the bottom of the hot end.
