3. Cleaning the Nozzle
The Nozzle will slowly accumulate bits of filament on the outside from picking up wisps, the filament curling especially when first bit
is extruded.... over time these will become hard and may stick out and make contact with the extruded filament pulling it along the
build plate.
So heat the nozzle and using a thick cloth, to avoid burning your fingers, make sure the outside is clean.
The inside of the nozzle can also become clogged due to impurities in the filament, the filament deteriorating as it cools.......
If so then this can reduce the filament flow, sometimes irregularly, resulting in thinner lines and debris in the filament.
To clean the nozzle:
● Heat it to at least the filament printing temperature, preferably to 260˚
● Remove the filament completely.
● Carefully clean the outside of the nozzle and gently clean the silicon cover around it.
● Use a correctly sized cleaning needle for the nozzle (the one included is for the standard 0.4mm nozzle)
and insert into the hot nozzle to clean it out and dislodge any blockage.
● Trim the bottom inch off the filament and re insert it.
● Extrude a few centimetres of filament to flush anything out.
If this doesn't cure the problem repeat the process. If that doesn't work consider changing the nozzle for a new one.

Do you have a question about the ENDER-3 V2 and is the answer not in the manual?
Questions and answers
I'm getting an error of "nozzle is too lowperature" can you assist?
To fix the "nozzle is too low temperature" error on your Creality Ender-3 V2, follow these steps:
1. Preheat the Nozzle:
- From the main menu, go to Prepare > Preheat PLA or Preheat ABS to set the default temperature for the selected filament.
- Alternatively, go to Control > Temperature > Nozzle Temperature, set the desired temperature (above 180°C), and confirm the change.
2. Check the Thermistor:
- If the temperature reading is incorrect or stuck at zero, inspect the thermistor wire for damage.
- If the thermistor is broken or disconnected, replace it to restore proper temperature readings.
3. Ensure Proper Wiring:
- Check that the thermistor and heater cartridge wires are securely connected to the mainboard.
- Loose or broken connections can prevent the nozzle from heating properly.
4. Restart the Printer:
- Power off the printer, wait a few seconds, and turn it back on to reset the system.
If the issue persists after these steps, replacing the thermistor or heater cartridge may be necessary.
