again

Unable to charge - Wall connection
too hot
Check outlet or Wall Connector
wiring
High temperature detected by Wall Connector alerts
indicate the building connection to the Wall Connector
is getting too warm, so charging has stopped to protect
the wiring and Wall Connector.
This is not typically an issue with your vehicle or your
Wall Connector, but rather an issue with the building
wiring. This may be caused by a loose building wiring
connection to the Wall Connector and can be
fixed
quickly by an electrician.
To regain normal charge operation, try the following
steps.
If the Wall Connector is plugged into a wall outlet, make
sure:
•
The plug is fully inserted into the receptacle / outlet
•
The plug / outlet area is not blocked or covered by
anything
•
There is no heat source nearby
If the issue persists or the Wall Connector is hard-wired,
contact an electrician to inspect the building wiring
connection to the Wall Connector. They should make
sure that all wires are properly connected and torqued
according to the installation guide for the Wall
Connector.
Wall Connector installation guides can be found here.
