See below for how to select suitable beans.
If you have a mesh chaff collector with an opaque chimney you will have to remove the chaff collector lid so that you can see the beans.
Take care to select ‘fan at 14700 rpm’ of ‘fan visual’. There are other calibration settings which should not be changed except under instructions from an authorized Kaffelogic service agent.
Fan speed calibration at 14700 rpm requires firmware version 7.10 or higher. If you need to update, see Update firmware.
If you have correctly calibrated your bean circulation, but are still experiencing scorched beans and/or bean lock, see Bean lock.
