Robot vacuum reports E16 or fan filter error; suction stops when filter is removed or installed incorrectly.

Safety first: Turn OFF the robot and remove the dustbin.

Steps to try:

• 1. Check filter installation: Ensure the HEPA filter is oriented correctly and fully inserted into its frame or slot.
• 2. Use genuine filter: Install a Gorenje‑approved filter. Non‑original filters may not engage the sensor correctly.
• 3. Inspect filter frame: Look for cracks or missing tabs that might prevent the filter from pressing the sensor.
• 4. Test operation: Reinstall the bin and start a cleaning cycle. If E16 persists, the airflow or filter presence sensor may be defective.
• 5. Replace sensor or bin assembly: Depending on design, replace the dustbin assembly (with integrated sensor) or the airflow sensor board.
