Step 2: Empty the Bin and Clean the Filters
- Remove the dust bin and empty it completely into a trash bag.
- Remove the pre-filter and the main filter as per your model’s instructions.
- Rinse the filters under cold water, wring out excess water, and let them air dry completely for at least 24 hours before reinstalling.
Step 3: Check for Blockages
- Inspect the wand, nozzles, and brush heads for any debris or obstructions.
- Clear out any blockages carefully using a straightened coat hanger or a long, flexible brush.
- Ensure all connections are securely reattached after cleaning.
Step 4: Inspect the Battery and Power Trigger
If the vacuum continues to pulse, check if the battery is charged and properly seated. A malfunctioning power trigger or low battery can cause pulsing. Consider replacing or servicing the battery if it’s old or not holding charge.
Step 5: Reset and Test the Vacuum
After completing the above steps, reassemble all parts. Turn on your Dyson vacuum and observe if the pulsing persists. If it does, consult the user manual or contact Dyson support for further assistance.
