Mower shows E005 and stops when tilted or on a slope; sometimes appears on flat ground

Safety: Turn the mower OFF and remove the battery connector before opening the electronics compartment.

• Verify environment: Ensure the mower is not operating on slopes steeper than the Mammotion specification. Avoid soft ground where wheels sink and cause extreme tilt.
• Check for impacts: Inspect the chassis for signs of heavy impact or deformation that could misalign the mainboard.
• Secure mainboard: Open the electronics cover and verify the main control board is firmly screwed down. Tighten any loose mounting screws.
• Connector check: Reseat the mainboard connectors, especially those labeled for IMU/tilt sensor if accessible.
• Firmware update: Using the Mammotion app (if supported), check for firmware updates that may address tilt sensor calibration issues.
• If E005 persists on level ground, the tilt sensor (often integrated on the mainboard) may be defective, requiring mainboard replacement.
