Quick Troubleshooting

Check these common charging issues before contacting support. If the charger displays an error code, refer to the Fault Code Guide below.

Charger does not start charging +

Make sure the charger is connected to a suitable power outlet and that the charging connector is fully inserted into the vehicle.

Unplug and reconnect the charging connector.
Make sure the wall outlet is supplying power.
Try another suitable outlet if available.
Check whether the charger display shows an error code.
If an error code appears, refer to the Fault Code Guide below.

Charger displays an error code +

When the charger detects a fault, an error code may appear on the display.

Check the error code shown on the charger display.
Error codes E1–E10 indicate different fault conditions.
Refer to the Fault Code Guide below for the corresponding fault and recommended action.

Charging starts but stops unexpectedly +

Charging may stop if the charger or vehicle becomes too hot, or if the charger detects an abnormal operating condition.

Stop charging and allow the charger and vehicle to cool down.
Check whether the charger display shows an error code.
If an error code appears, refer to the Fault Code Guide below.
Reconnect the charger after the equipment has cooled down.

Charging speed is slower than expected +

Actual charging current may be limited by the vehicle, temperature conditions, or the selected charging current.

Check the charging-current setting on the vehicle.
Check the selected current on the charger.
Make sure the charger and vehicle are not overheating.

Charging current cannot reach the selected amperage +

The vehicle may have its own charging-current limit, which can prevent the charger from reaching the selected amperage.

Check the charging settings in your vehicle.
Remove or increase the vehicle-side current limit if appropriate.
Confirm that the selected charging current matches the power source.

Ground fault or grounding problem +

The charger requires a properly grounded power outlet.

Make sure the outlet is properly grounded.
Do not continue charging if a ground fault is detected.
Try another properly grounded outlet if available.

Charger or vehicle becomes unusually hot +

The charger includes temperature protection and may reduce charging power or stop charging if excessive heat is detected.

Stop charging if the charger or vehicle becomes unusually hot.
Allow the equipment to cool before charging again.
Check the plug and outlet for abnormal heat or visible damage.

Delayed charging does not start immediately +

If scheduled charging is enabled, charging will begin only after the selected delay time has elapsed.

Check the delay time shown on the charger display.
Each timer-button press increases the delay by 1 hour.
The maximum scheduled delay is 12 hours.
