How to Fix / Troubleshooting
Safety first: Remove the battery pack. Do not operate the vacuum with the housing open.
- Visual inspection: Check the exterior for cracks or signs of impact, especially near the motor housing and handle.
- Open housing (if comfortable): Remove screws and carefully separate the housing to access the main control PCB and motor module.
- Check connectors: Ensure all multi‑pin connectors between the PCB, motor, and battery terminals are fully seated. Gently press them in until they click.
- Inspect PCB: Look for burnt components, cracked boards, or loose components. Any visible damage usually requires PCB replacement.
- Reassemble and test: After reseating connectors, reassemble the housing and test. If E9 remains, replace the main control PCB or motor module as specified by Logik parts documentation.
