Possible Causes
Shorted windings in main suction motor, Damaged motor wiring harness, Debris causing motor to stall, Faulty motor driver MOSFETs on PCB
How to Fix / Troubleshooting
Safety first: Remove the battery pack. Do not continue to run the vacuum repeatedly as this can damage electronics further.
- 1. Check for mechanical blockage: Remove dust bin and filters. Inspect the motor inlet for foreign objects. If accessible, gently rotate the motor fan with a non-metallic tool to ensure it is not seized.
- 2. Test with minimal load: Reinstall the battery and run the vacuum without any attachments. If E14 appears immediately, the fault is internal to the motor or PCB.
- 3. Avoid DIY board repair: Overcurrent faults often indicate failing power components on the PCB. Component-level repair requires electronics expertise.
- 4. Seek service: Have a technician test the motor windings and replace the main suction motor or control PCB as needed.
