How to Fix / Troubleshooting

Safety first: Remove the battery immediately if abnormal noise occurs to prevent further damage.

Check for debris: Remove hose and inspect the inlet for large objects that may have reached the fan area.
Listen to motor spin-down: Briefly run the vacuum and listen as it stops. A rough, scraping sound indicates bearing or fan issues.
Do not continue use: Operating with failing bearings can cause catastrophic motor failure.
Service required: Motor and fan assemblies are typically replaced as a unit. Have a technician replace the motor/fan assembly.
