The filament is not extruded from the nozzle, either during printing or through manual loading.
The filament could become stuck in the nozzle due to accumulated carbonization over time from exposure to excessively high temperatures.

Heat the nozzle to a temperature slightly higher than the typical printing temperature of the filament stuck inside, such as around 220°C for PLA.
Use the metal string to carefully push the clogged material upwards through the nozzle tip.
Clean the filament stuck to the nozzle surface with the wire brush or tweezers.
To prevent any burn injuries, it’s recommended to wear heat-resistant gloves during this operation.

Load the filament again. The loading and extruding processes are supposed to be smooth.
If you notice that the extruded filament is thinner than usual, there may still be some cloggings in the nozzle. Please repeat the steps to clean the nozzle thoroughly.
If the filament still can not be extruded, please refer to Filament is not extruded for information about other possible causes and their solutions.
