My bbshd pas stopped working all of a sudden. My speedometer works and the sensor gets reading from the magnet passing by. I can see km/h change as I pedal or use the throttle.

Speaking of throttle and motor, all works fine, just that I'm not getting any pedal assist on any of the 9 levels. Bike works fine when using the thumb throttle.

In the display under faultcode info I can see E-CODE0: 21

Cables look nice and intact.

Help is appreciated.
