Error code 1057 means that the charger detected a residual current (earth leakage) during charging and stopped the session for safety. The cause can be in the car, the charging cable or the installation.
What to do
On a socket model, unplug the charging cable from the charger. Plug the cable into the car again and start a new charging session.
If the error returns, reboot the charger from the web interface or Connect Hub, or ask your charge point operator to reset it from the back office. If the web interface is not reachable, perform a power cycle: switch off the power to the charger at the fuse box, wait a moment and switch it back on. Then try again.
Does this error occur more often with the same car, also at other chargers? Then the cause is most likely in the car. Contact your car dealer.
If it only happens at this charger, ask your installer to test with a different charging cable of the same type.
If the error persists, download the diagnostics of the charger and contact Peblar support or your installer.
