I just noticed this issue in my past 2 roasting sessions and wanted to make sure my machine is not broken.
I roasted the Brazilian beans using the Filter and Espresso profiles provided. My understanding from the profiles is that the roasting should end at 6:19m and 6:04m (excluding the cooling periods in each profile). However, if I actually time it using a separate timer, starting from when I push the green start button right to when the cooling indicator turns blue, the actual times are about 20-23 seconds longer. Is this right? Does the countdown indicator in the Ikawa somehow start later? This has got me confused, considering it seems that 20s would have a theoretically big impact on modulating flavor?
If this is not the way the machine is supposed to work, then maybe I can exchange it (still). I also have the initial problem that one of the screwheads was already broken. The screwhead fell off when I had to dump the beans in my very first roast. This didn’t bother me at the beginning as the rest of the screw was still in there, so there’s no danger of anything coming lose. However, if the timer is also off, then maybe I can send it back. I just got this at the beginning of the month.
