Vacuum does not recognize the battery; E06 displayed and battery icon blinks

Safety first: Remove the battery and disconnect the charger from mains before inspection.

• 1. Inspect battery contacts: Check the metal terminals on the battery and inside the battery compartment for dirt, corrosion, or deformation. Clean gently with a dry, lint‑free cloth.
• 2. Check for bent pins: If any contact pins are bent, do not force the battery in. Slightly straighten with a non‑metallic tool if possible. If severely damaged, the handle/battery housing may need replacement.
• 3. Confirm genuine Panasonic battery: Ensure the battery pack is the correct model and genuine Panasonic. Third‑party packs may not communicate correctly and can trigger E06.
• 4. Reseat the battery: Insert the battery firmly until it clicks. Remove and reinsert a few times to ensure a solid connection.
• 5. Test with another battery (if available): If a second compatible battery works normally, the original pack has an internal PCB or communication fault and should be replaced.
• 6. If all batteries fail: The main control PCB or battery connector harness in the vacuum handle may be defective. This requires professional diagnosis and board replacement.
