Possible Causes
Main brush heavily loaded with debris, Carpet too thick causing high resistance, Partial short in brush motor wiring, Failing motor driver on main PCB
How to Fix / Troubleshooting
Safety: Turn the robot OFF.
- Thoroughly clean brushes: Remove and clean the main brush and side brushes, ensuring they spin freely.
- Test on hard floor: Run the robot on a hard surface to see if the error occurs only on thick carpets.
- Reduce load: If the carpet is very deep pile, limit use in that area or create no-go zones if your model supports it.
Persistent E12 on normal floors after cleaning suggests a failing motor or main control board that may require professional replacement.
