Robot vacuum shows E14 and navigation is erratic; robot may spin or fail to map rooms (on mapping‑capable Coredy models).

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Internal gyroscope calibration lost, Strong magnetic interference, IMU board failure

Safety first: Place the robot on a level, hard floor away from large metal objects.

Reboot robot: Turn the main power switch OFF for 30 seconds, then back ON.
Perform calibration (if supported): Some Coredy models allow sensor calibration via the app. Follow the in‑app instructions to recalibrate the gyroscope/IMU.
Avoid interference: Do not store or operate the robot directly on metal plates or near strong magnets.

If E14 persists after calibration, the internal IMU board may be defective and require replacement.
