How to Fix / Troubleshooting

Safety first: Turn off and remove the battery. Do not run the motor with the housing open.

  • Rule out normal noise: Test the vacuum without the floor head and wand. If the noise persists, it is likely from the main motor.
  • Inspect for debris: Open the main body to access the motor housing. Look for foreign objects near the fan.
  • Check fan condition: If fan blades are chipped or bent, the motor assembly should be replaced.
  • Replace motor: Install a new Main Motor Assembly following a service guide, ensuring all seals are correctly fitted.
