Heater decoupled / DEF / DEC message on screen
This error presents itself when a part of the heater circuit is not working.
It can generally be caused by one of the following things:
Bad electrical connection with the hot end cartridge.
The white big connector of the hot end should be plugged all the way onto the printed circuit board on the
print head.
If you get the error, please try to pull off the connector sideways and then plug it back on firmly.
Please note: the connector also can be plugged on back to front. This does not damage anything, but it will
not work either.
Turn off and on the printer to reset it after the the hot end has been reconnected.
The heater catrtridge/thermistor (= temperature sensor) is not mounted right
A bad thermal contact between components and aluminum body can cause the printer to detect that the
temperature is rising too slow to be credible.
Solution: tighten set screws that fix the heater cartridge and/or the thermistor.
Be a bit careful with the thermistor set screw, overtightening it may damage the thermistor.
The heater cartridge is broken.
The printer detects that the temperature does not rise when the heater is activated.
Solution: replace the thermistor/heater set.
The thermistor is broken.
The printer decides it is broken when the temperature measured is lower than 0°C or higher than 275°C, or
when the temperature does not seem to rise fast enough.
Solution: replace the thermistor/heater set.
Thermistor wires are (partially) broken.
This can sometimes be seen as a very fast fluctuation of temperature.
Solution: replace the thermistor/heater set.
