Vacuum shows E11; LED headlight on floor nozzle flickers or does not turn on while suction works.

Safety first: Remove the battery and detach the nozzle before inspecting wiring.

• 1. Reseat nozzle: Remove and firmly reattach the floor nozzle to the wand or main body to ensure a solid electrical connection.
• 2. Inspect connectors: Look for bent or recessed pins at the nozzle connection. Straighten gently if slightly bent.
• 3. Test with another nozzle (if available): If a second LG nozzle works normally, the original nozzle's LED or internal wiring is defective.
• 4. Since LED and wiring are integrated in most LG nozzles, the typical repair is to replace the entire nozzle assembly rather than attempting component-level repair.
