Cordless Shark vacuum shows an error when the LED headlight or floor nozzle is connected; unit works without nozzle but errors with it attached

Safety first: Remove the battery before inspecting connectors or accessories.

• 1. Test handheld unit alone: Remove the wand and floor nozzle. Install the battery and run the handheld unit only. If it runs normally, the fault is likely in the wand or nozzle.
• 2. Inspect connector pins: Examine the electrical connectors at the end of the wand, on the floor nozzle, and on the handheld unit. Look for bent, recessed, or corroded pins. Straighten slightly bent pins carefully with a small tool.
• 3. Check wand continuity (if possible): If you have a multimeter and are comfortable using it, test continuity of the power lines through the wand. A broken wire will show as open circuit and requires wand replacement.
• 4. Test with another nozzle or wand: If you have another compatible Shark nozzle or wand, swap components to isolate the faulty part.
• 5. Replace faulty accessory: If the error only appears when a specific nozzle or wand is attached, replace that component with a genuine Shark replacement.
