Error 2407 Creality Hi combo

I bought my Creality Hi Combo printer and when I start it, it shows error 2407… something with the nozzle. What is it?

I have the same error in a new Creality Hi Combo. When doing the self check the noozle does not respond and sends the unknown error: 2407 in the wiki, there is no reference to the error whatsoever. should i return the printer?

i fixed mine!! even if the error showed that it was noozle related mi issue was 1 of the Z motors disconnected at the motor not at the printer. I recommend to enter to the fluid interface of the printer printeripaddress:4408 and try to set the temperature of the noozle there if it heats up probably is the same problem and you need to re check all the z motor connections @CREALITY please fix this unkwon errors because in my case should been easier to dignose with some meaningful Z motor disconnected message or something like that
