The fix

Roborock OEM battery pack

Battery management system fault — overheat, degraded cells, or loose connector

$25-45 moderate difficulty 20-30 min Tools: screwdriver

Diagnose first: Let the robot cool to room temperature and try a full discharge/charge cycle before replacing anything — a real overheat event resolves on its own. Use a genuine Roborock or well-reviewed OEM-equivalent battery; generic packs commonly don't seat correctly with the battery management system and can retrigger this same error.

How to fix it

  1. Let the robot cool to room temperature for at least 1 hour.
  2. Try a full discharge then full charge cycle.
  3. Power-cycle the robot using the hardware switch.
  4. If the error persists, the battery pack needs replacement (4 screws under the cover on most models).
  5. Use only genuine Roborock or quality OEM-equivalent batteries — generic packs may not seat properly with the BMS.
