How to Fix / Troubleshooting
Safety first: Turn OFF the robot, remove it from the dock, and disconnect the battery before opening the housing.
- Visual inspection: Open the top cover to access the main PCB. Look for burn marks, corrosion, or loose connectors.
- Reseat connectors: Carefully unplug and replug ribbon cables and harnesses to ensure solid connections.
- Dry any moisture: If there are signs of liquid ingress, allow the unit to dry completely for at least 48 hours in a warm, dry place. Do not power it on while wet.
- Board replacement: If E18 persists and there is visible damage, replace the Main Control Board (Main PCB) with the exact part number for your Honiture model. This is a complex repair and may be best handled by a professional.
