How to Fix / Troubleshooting

Safety: Intermittent faults can precede complete failure. Address promptly.

  • Observe pattern: Note whether charging stops at similar times or temperatures, which may indicate thermal issues.
  • Inspect wiring: With power off, check all internal terminals for tightness and signs of arcing or heat.
  • Check cable strain relief: Ensure the cable is properly supported and not pulling on the Wall Connector entry point.
  • Try different cable positions: Slightly reposition the cable during charging; if movement causes interruption, internal cable conductors may be damaged and the unit should be replaced.
