Depending on your settings, light may stay on for a few seconds. But if they remain on, you may have moved the lights setting (on the left-hand stalk) away from auto, e.g. to parking lights. Turn the setting back to auto.
A charge doesn’t start
E.g. the car’s charging light blinks white, but then turns off and never turns blue.
Restart the charge while gently pushing the plug forward and upward, into the socket. This may help the charger’s lock pin engage. This issue has been seen e.g. with Engie/GeniePoint chargers and certain InstaVolt chargers.
