Robot vacuum displays E14; may indicate 'Navigation error' or 'Sensor calibration error'.

Safety first: Turn OFF the robot and remove it from the dock.

• Place on level surface: Put the robot on a flat, level floor away from metal objects and magnets.
• Power cycle: Turn the robot OFF for 2 minutes, then turn it ON and allow it to remain stationary for 30–60 seconds to auto-calibrate (if supported by your Philips model).
• Check for impacts: Inspect the housing for signs of heavy impact or drop damage that could have affected internal sensors.
• Update firmware: Using the Philips app, check for and install any available firmware updates that may address navigation issues.
• Test navigation: Start a cleaning cycle in an open area and observe if the robot moves in straight lines or behaves erratically.
• Persistent E14: If the error returns, the internal IMU/gyroscope module or main PCB is likely faulty and should be replaced by a professional technician.
