What happened?

The printer will display the message "Check the heatbreak thermistor wiring for possible damage" if the heatbreak temperature measures more than 100 °C at any point. In this case, the printer will stop the heating and display the message on the screen. 

Error name: Heatbreak Maxtemp error

Error code: #17212 

Most often, this error happens due to wiring damage or connection issue on the heatbreak thermistor cable. 

How to fix it?

A visual inspection

Check the Dwarf board where the heatbreak thermistor resides, to ensure that no wires have broken off or are disconnected. 

Before you start, make sure:

  • the filament is unloaded from the extruder
  • the printer is turned OFF and unplugged from electricity
  • the hotend and the heatbed are cooled down to ambient temperature
Since we will handle tools and work with the extruder high above the heatbed, it is necessary to protect it.

Place an empty Prusament cardboard box approximately to the front center part of the heatbed. Move the X-axis all the way to the front side of the printer, and move the extruder approximately to the center of the X-axis.

Open the dwarf-cover-door to access the Dwarf board. Check that all the connectors are secure in their sockets, according to the picture below. Focus on the heatbreak thermistor cable. Though unlikely, rough shipping or handling could have shaken the heatbreak thermistor cable loose. 

 
In case you haven't found visible damage on the inspected parts, or in case of any doubts, do not hesitate to contact our customer support.
