Possible Causes

Damaged wiring in extension wand, Dirty or bent electrical contacts between wand and floor head, Failed PCB inside TCL motorized floor head, Loose connector inside main body where wand plugs in

How to Fix / Troubleshooting

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

  • 1. Remove and reattach wand: Detach the wand from the main body and floor head. Reattach firmly until you hear a click at both ends.
  • 2. Clean contacts: Inspect the metal contacts at the wand ends and on the floor head and main body. Wipe gently with a dry, lint‑free cloth. Do not use liquids.
  • 3. Visual inspection: Look for bent pins, burn marks, or melted plastic around the connectors. If any are found, the affected part should be replaced.
  • 4. Test with another attachment: If you have a smaller powered tool (e.g., TCL mini motorized brush), connect it directly to the main body. If it works, the issue is likely in the floor head or wand.

Next step: Persistent E7 indicates a communication or power fault to the floor head. Replace the extension wand or motorized floor head assembly as indicated by your tests, or have a technician check continuity and replace the internal harness or PCB.
