This problem is almost always centered on the and its critical partner, the NTC temperature sensor .
On Krups espresso machines, typically indicates a heating system failure , often specifically related to a faulty NTC temperature sensor . This sensor monitors the temperature of the thermoblock (the heating element), and if the machine cannot detect a proper signal from it, it will halt operation for safety.
