How to Fix / Troubleshooting
Safety first: Turn OFF the robot and remove the dustbin.
Steps to try:
- 1. Check for obstructions: Look into the suction inlet and fan intake for any visible debris. Remove carefully.
- 2. Clean filters: A severely clogged filter can cause abnormal fan load. Clean or replace the HEPA and pre‑filters.
- 3. Listen to the fan: After reassembly, run the robot and listen. A rattling or scraping noise indicates internal fan damage.
- 4. Inspect wiring (advanced): Open the housing to access the fan module and verify the connector is fully seated on the main board.
- 5. Replace fan assembly: If E12 continues, replace the complete suction fan assembly, which includes the motor and speed sensor.
