Vacuum shows “Err 9”; unit may not detect attachments or may shut off when accessories are connected.

Safety first: Turn OFF the vacuum and remove the battery before inspecting connectors.

• Inspect connectors: Look at the electrical contacts on the wand, motorized nozzle, and handheld body. Ensure pins are straight and not recessed.
• Clean contacts: Use a dry cloth or cotton swab to gently clean the metal contacts. Do not use liquids or abrasives.
• Test with different accessories: Attach a non‑powered tool (like a crevice tool) and see if the vacuum runs normally. Then test the motorized nozzle. If Err 9 only appears with one accessory, that accessory is likely faulty.
• Check wand continuity: If available, use a multimeter to verify continuity through the wand’s electrical paths. Replace the wand if open circuits are found.
• Replace faulty part: Replace the motorized nozzle, wand, or main body connector assembly depending on which component consistently triggers Err 9.
