Inspect for Blockages

  • Examine the wand, hose, and cleaner head for any debris or obstructions.
  • Clear out any visible blockages carefully to ensure unobstructed airflow.
  • Check the brush bar and remove tangled hair or debris that could impede performance.

Check Sensor and Connection Areas

Wipe the sensors located near the filters and other connection points with a soft, dry cloth to remove dust or dirt that could interfere with sensor readings.

Ensure all components are securely connected and properly seated.

Test Battery and Power

Make sure the vacuum is fully charged. If pulsing persists, try resetting the vacuum or reconnecting the battery if possible.

If the vacuum has been used extensively, consider replacing the battery or contacting Dyson support for further diagnostics.

Final Checks and Reassembly

Reassemble all parts securely. Turn on the vacuum and test if the pulsing issue persists.

If all steps fail, contact Dyson customer support for professional assistance.
