Robot vacuum reports E15; internal temperature too high, robot shuts down during or after cleaning.

Safety first: If the robot feels hot to the touch, turn it OFF and allow it to cool for at least 30 minutes before further inspection.

• 1. Move to cooler area: Ensure the robot is used in an environment within the temperature range specified by Electrolux (typically 10–35°C / 50–95°F).
• 2. Clean filters and airflow path: Remove and clean the dustbin, pre-filter, and HEPA filter. Clear any blockages in the suction channel and vents.
• 3. Check for overloading: Avoid using maximum suction mode continuously on thick carpets if the robot frequently overheats.
• 4. Inspect vents: Make sure all ventilation openings on the robot body are free of dust and not blocked by furniture when docked.
• 5. Battery temperature: If the battery area is excessively hot, allow extended cooling time and then test again. Repeated overheating may indicate a failing battery pack.
• 6. If E15 recurs quickly: The internal temperature sensor or main PCB may be faulty. Professional diagnosis is recommended; parts may include the Electrolux main control board or battery pack.
