Possible Causes

Blocked vents around motor housing, Prolonged use on Turbo/Max mode, Clogged filters causing heat buildup, Failing cooling fan or partially blocked cooling path

How to Fix / Troubleshooting

Safety: Turn off the vacuum, remove the battery, and allow the unit to cool for at least 30 minutes.

  • Check ventilation: Inspect all air vents on the motor housing and handle. Remove dust buildup with a soft brush or compressed air.
  • Clean filters and bin: Ensure pre-motor and HEPA filters are clean and dry. Empty the dustbin and clean the cyclone shroud.
  • Reduce load: Avoid using Max/Turbo mode continuously for long periods. Alternate between modes and allow short rest periods.
  • Inspect for obstructions: Confirm there are no blockages in the wand, floor head, or accessories that could restrict airflow.

If E5 recurs quickly even with clean filters and clear airflow, the internal temperature sensor, cooling fan, or motor may be failing. Seek professional service; continued use may cause permanent damage.
