Possible Causes
Worn motor bearings in digital motor, Damaged fan blades, Air leak at motor seals, Cracked housing near motor
How to Fix / Troubleshooting
Safety: Remove the battery before inspection. Do not run the vacuum for long periods if the noise is severe.
- Isolate the source: Run the vacuum briefly without attachments to confirm the noise comes from the main body, not the nozzle.
- Check for air leaks: Listen around the dust bin and filter seals for whistling. Reseat the bin and filters and ensure all latches are fully closed.
- Inspect motor area: If the noise is clearly from the motor and sounds like grinding or screeching, the motor bearings are likely worn.
- Replace motor assembly: Motor bearing or fan damage is not user-repairable. Replace the digital motor assembly through a service center.
