How to Fix / Troubleshooting

Emergency safety: Immediately stop using the charger. If safe, isolate power at the consumer unit. If fire is present, call emergency services.

  • 1. Isolate power: Turn off the dedicated breaker/isolator for the charger. Do not turn it back on.
  • 2. Do not open casing: Smoke may contain harmful fumes. Allow the unit to cool and ventilate the area.
  • 3. Inspect externally: Once safe, look for melted plastic, scorch marks, or deformed casing.
  • 4. Professional assessment: A qualified technician must open the unit, identify the failed component(s), and determine whether repair or full replacement is required. Often, the main PCB and contactor will need replacement.
