I’m having a problem these last weeks with my Bullet V2 during PH with last stable firmware
I usually roast 1200g batches so I always preheat to 310 °C IBTS.
While the Bullet preheats, I’m usually around preparing my roasting session, weighing batches, until the Bullet calls me to charge.
But these last weeks, when preheating, the Bullet throws the error when it exceeds 245°C with the bean probe all the time when is preheating, It appears that the Bullet is intentionally seeking to overheat.
I cleaned the Bullet thoroughly, cleaned the glass of the IBTS, cleaned the bean probe, all the chaff collector, the propeller and the metal mesh very well with espresso cleaner. Also I calibrated the fan few times.
The Bullet continues to overheat, The only thing I have seen that works to avoid the error is to remove the chute plug when it is at 235°C, like that the temperature get stable.
The ambient temperature doesn’t exceed 22°C.
