How to Fix / Troubleshooting

Safety first: Remove the battery before opening the housing.

Steps to try:

  • Recreate symptom: With the vacuum running (battery installed), gently tilt it and note when it shuts off. Then remove the battery.
  • Inspect battery fit: Ensure the battery does not move when the unit is tilted. Replace worn latches if necessary.
  • Open housing (advanced): Inspect wiring harnesses and connectors for strain or partial disconnection. Reseat all connectors.
  • Check for cracked solder joints: Examine the main PCB for cracks, especially around heavy components. Replace the PCB if damage is found.
