Hey,
this has never happened before. I did my third batch of the day and started preheating for the fourth one ,as normal. I noticed after some minutes, that the temperature was actually dropping instead of rising even though the Bullet was in preheat mode and the power showed P7, as normally.
I cooled it down, cleaned the sensor, and started the preheat again. I managed to do the first batch normally, but then the same thing happened, the temperature was dropping in the preheat mode.
Anyone knows what could be the problem?
