Possible Causes

Incorrect charger voltage, Faulty charger output, Battery BMS detecting abnormal voltage, Power surge damage

How to Fix / Troubleshooting

Safety first: Unplug the charger from the wall before inspection.

  • Verify charger model: Confirm that you are using the original Electrolux charger supplied with the vacuum or an approved replacement with the correct voltage and current rating.
  • Try another outlet: Plug the charger into a different wall socket to rule out wiring issues.
  • Check charger cable and plug: Inspect for cuts, kinks, or bent pins. Do not use a damaged charger.
  • Test with another charger (if available): If a second compatible charger works, replace the faulty one.
  • Battery replacement: If B2 persists with a known-good charger, the battery’s BMS may be damaged and the battery pack should be replaced.
