Ok, let me try to explain and let me know if anything is not clear.

  • Make sure you run the latest firmware. If you don't or if you are not sure, follow these instructions (connect to pc via cable, install firmware via Cura). 
  • If you look at the back of your printhead you should be able to see the backside of your hot end. In the hot end are 2 cables, heater cartridge (that generates heat) and PT100 (which reads the temperature). They both need to be inserted fully. If you are not sure, you can share a photo. 
  • If you look at the bottom of the printhead, you can check if the tip of the nozzle is not touching the metal fan bracket. If it does, the heat could be conducted away from the nozzle because both being metal, creating the error. If they touch, move the fan bracket so they no longer touch. Here you can see that they don't touch:

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
