When I was cleaning the inside cover and the IBTS lens, I had a bean trapped there. It happens pretty often.
I took a small piece of stainless steel wire (sometimes called piano wire) and created a loop and loosened the nut for the Bean Temp Probe and put the loop on there and re-tightened the nut.
Not sure if I’ll get in trouble recommending this, but replacing the screws with a button head screw (the ones holding the front plate, different size of course) could be a more elegant solution.
This has such an impact on temp readings! I’ve been pushing any beans out between roasts, but should have upgraded to a better part or added wire a long time ago. This is one of the many frustrating things about the Bullet, and Part of why I am contemplating leaving the platform once I can afford it.
