Possible Causes

Partially blocked filters, Restricted airflow in wand or nozzle, Failing thermal cut‑out switch, Motor overheating due to wear

How to Fix / Troubleshooting

Safety first: Remove the battery and allow the unit to cool for at least 30 minutes.

  • Deep‑clean filters: Remove and thoroughly clean pre‑motor and post‑motor filters as per the user manual. Ensure they are completely dry before refitting.
  • Check all air paths: Inspect the dust bin inlet, cyclone, wand, and nozzle for any partial blockages.
  • Short test runs: After reassembly, test the vacuum in short bursts on low power to see if the cut‑out still trips.

If the vacuum continues to shut off quickly with clean filters and clear airflow, the thermal cut‑out or motor is likely failing and should be inspected by a technician.
