Possible Causes

Shorted motor windings, Pinched or damaged internal wiring harness, Liquid damage causing conductive paths, Failed power MOSFET on control board

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.
