Possible Causes
Worn bearings in main suction motor, Air leak at dust bin or filter seal, Cracked cyclone or housing, Debris contacting motor fan
How to Fix / Troubleshooting
Safety first: Remove the battery before inspection.
- Check seals and fit: Ensure the dust bin and filters are fully seated and that all latches are closed. Air leaks can cause whistling.
- Inspect for cracks: Look for cracks in the bin, cyclone, or housing that may create high‑velocity air leaks.
- Listen to motor alone: Remove the floor head and wand, then run the vacuum briefly. If the whine persists and seems to come from the motor area, the motor bearings are likely worn.
- Service motor: Worn bearings require replacement of the main suction motor assembly. This is a complex repair best handled by a technician.
