Error F11
Cause Suggested solution
The main contactor of the wallbox does not
close.
The wallbox automatically re-initiates the charging procedure
after 30 seconds and repeats this process twice. After
three failed reinitiation attempts, the charging procedure is
terminated.
If this error persists and the charging procedure is not initiat-
ed automatically, the wallbox must be taken out of operation
and checked: please contact the specialist electrical contrac-
tor who has carried out the installation of your wallbox and
any accessories.
Error F15
Description Flash pattern
Both the green battery icon and the blue power
symbol remain ON during the cycle.
The red warning symbol flashes twice.
Cause Suggested solution
The current monitoring device has detected a
load imbalance between the phases, and has
reduced the maximum charging current to 20A.
Charging operations are still possible.
Disconnect the charging cable from the vehicle (socket vari-
ants: and from the socket) and then plug it back in.
Should this not reset the error, please check the electrical
connection and parameters for the wallbox and set the
charging current to a value above 20A.
If the error cannot be resolved, please contact the specialist
electrical contractor who has carried out the installation of
your wallbox and any accessories.
Errors F16 and F17
Description Flash pattern
Both the green battery icon and the blue power
symbol remain ON during the cycle.
The red warning symbol flashes twice.
Cause Suggested solution
Data transfer to the integrated current
monitoring device is disrupted: The maximum
charging current is limited to 10A while this
error persists. Charging operations are still
possible.
The temperature monitoring device has
detected a temperature above 60° Celsius
inside the housing: The maximum charging
current is limited to 6A. Charging operations

or the temperature inside the housing has fallen to below
60° Celsius.
If the error repeats or persists, the wallbox must be cooled
and/or shaded more effectively at the installation site.
Please contact a qualified specialist electrical contractor to
check and resolve the error, or to move the installation site of
