Thermomix TM5 shows error C153

Hi all

My thermomix is showing the C153 error: device will automatically shutdown, please confirm. I can only press OK on the touchscreen and the device shuts down. After restart, the same message is shown again.

I’ve found a tutorial on this site which speaks about the same error, but also movements with the arms. My device doesn’t move its arms.

Does anybody has any ideas?

Thanks in advance!

Regards

Yannick
