How to Fix / Troubleshooting
Safety first: Immediately remove the battery. Do not attempt to power on the vacuum again until it has been inspected. Risk of fire or further damage exists.
- Inspect for liquid damage: Check the dust bin, motor vents, and body for signs of water or other liquids. If present, do not attempt to dry and reuse; internal corrosion is likely.
- Smell for burning: A burnt odor from the motor or body indicates component failure.
- Do not open battery: Never open the battery pack to look for shorts.
- Service requirement: E15 indicates a serious internal fault. The unit should be evaluated by a professional technician, and components such as the motor, wiring harness, or main PCB may need replacement.
