Vacuum shows C18 and the self-standing charging station does not recognize the unit properly.

Safety first: Unplug the stand from the wall before inspection.

• Check alignment: Ensure the vacuum is seated correctly in the stand, following the user manual. Adjust the stand position if needed.
• Inspect magnets and guides: Look for broken plastic guides or missing magnets that help position the vacuum.
• Clean docking area: Remove dust and debris from the stand cradle and the vacuum contact points.
• Test charging: Confirm that the battery still charges even if C18 appears. If not, the stand electronics may be faulty.
• If C18 continues: Replace the self-standing charging station or have it serviced.
