Thank you guys, but i am pretty sure that this issue is not caused by thermistor.
The printer will show 5C without the thermistor being connected to the small pcb on the carriage.
Even after disconnecting the pcb connector from the mainboard i get the 5C reading after powering on the printer.
I guess something got fried on the mainboard

If you are using E3D clone, the screw fix the themistor on the heat block may be screwed too tight and make two wire of the themistor partially shortcurcuited. Just power off the printer, loose that screw a little bit and reboot the printer.

This is only common problem for E3D clone, very easy to fix. If you have the genuine E3D, I have no idea what is going on.

Your thermistor could be bad. You could try swapping the bed and hotend thermistor connections at the main board and see if the issue follows the thermistor or stays the same.

Hi,

i have dV 1.0 running repetier and a E3D V6 Hotend. Everything was working so far.
All of a sudden the hotend temperature gets stucked at 5C after switching on the printer.
The printers shows the DEC error if a raise the temperature. Seems like i have shortened out something
I have tried to bypass the small PCB , but without any success.
Does anybody know a solution for this problem ?

thanks !
