Clean or Replace Filters
Dirty filters can cause airflow issues leading to pulsing. Remove the pre-filter and main filter from your Dyson V15.
If using the 3Pack Pre Filters Replacement (asin=B091D4YRYG), rinse thoroughly with water, then air dry completely before reinstalling. For V10 filters, replace with the new set if they appear clogged or dirty.
Ensure filters are dry before reinserting to prevent damage.
Inspect the Battery and Power Settings
- Check that the battery is fully charged and properly seated.
- Ensure you are using the correct power mode for your cleaning task.
- If the vacuum continues pulsing, try resetting the device by turning it off, removing the battery if possible, waiting a few minutes, then reinserting and powering on.
Perform a Full Reset and Test
Turn off and unplug the vacuum. Press and hold the power button for 10 seconds to discharge residual power. Reassemble and turn it on to see if the pulsing persists. If it does, proceed to further troubleshooting or contact Dyson support.
Tips and Warnings
