I had this Baratza Sette 270 in the shop the other day for an intermittent/no power fault and I could foresee the issue affecting other Sette grinders due to the inherent design so this may be of assistance.
The complaint was the screen on the front would sometimes flicker but mostly would just be dead and the grinder would not respond to any buttons.
The cause was a broken leg on one of the two choke coils on the power supply board. These coils hang upside down when the grinder is in use.
They have no glue or adhesives to secure them to the PCB and the grinder vibrates quite a lot when it runs. The vibration, possibly along with a poor soldering job, allowed the leg to break and touch off to the pad causing the intermittent or no connection fault.
I resoldered all of the legs and added an extra length of solid core wire to the broken one so it would contact the PCB properly. The coil was then glued in place and glue was added to the other coil to secure it.
If you are having similar issues with your grinder, have a look and see if yours has done this too. The grinders are all built the same with the coils hanging upside down so it's not unlikely it's happened before and will happen again.
