The fix
Roborock side brush motor replacement
Side brush motor circuit fault (over-current/short), distinct from a simple jam
Diagnose first: Clear hair from the motor shaft and power-cycle first — Roborock's own guidance for this error is to reset the system, and that resolves many cases without a part. Only replace the motor if the error keeps returning on a hair-free, freely-spinning brush.
