Internal Communication Bus Fault
E010
Charger shows E010 and will not start; often logged after repeated overcurrent events.
Overcurrent / Output Overload Protection
E011
Siemens charger displays E011; charging stops and cannot be restarted until power is cycled.
DC Residual Current Detection Fault
E012
Display shows E012; charger powers but cannot lock or unlock the connector (for models with motorized lock).
Connector Locking Mechanism Fault
E013
Charger shows E013; charging is disabled and an internal fault LED may be lit.
Isolation Monitoring Fault (for IT/isolated systems)
E014
Siemens wallbox shows E014; unit appears dead to the vehicle but display or LEDs may still be on.
Output Relay / Contactor Control Fault
E015
Charger displays E015; unit may reboot repeatedly or freeze during operation.
Internal Power Supply Fault
E016
E016 displayed; charger refuses to start when connected to a load management or smart home system.
External Control / Load Management Communication Fault
E017
Charger shows E017; RFID cards or user authentication fail and charging is blocked.
RFID / User Authentication Fault
E018
E018 displayed; charger cannot connect to backend or app, and remote control features are unavailable.
Network Connectivity Fault
E019
Charger shows E019; scheduled charging or dynamic load management does not function correctly.
Real-Time Clock / Time Synchronization Fault
E020
E020 displayed; charger indicates ‘phase error’ or ‘phase rotation fault’ on three-phase installations.
Phase Sequence / Phase Loss Fault
Symptom
Charger emits a high-pitched whining or buzzing noise during operation.
Magnetostriction / Switching Noise from Power Electronics
Symptom
Charger randomly reboots during charging sessions without any visible error code.
Internal Reset / Watchdog Trigger
Symptom
Charger’s front LEDs or display flicker or dim when a vehicle is connected or when other household loads switch on.
Supply Voltage Sag / Internal Power Instability
Symptom
Charging is very slow compared to charger rating; vehicle only draws a low current even though a higher current is configured.
Pilot Current Limitation / Derating
Symptom
Front display or LED panel on Siemens charger is blank or unreadable, but the vehicle still charges normally.
Display / HMI Module Failure
Symptom
Intermittent charging: sessions start but stop randomly without any error code on the Siemens charger.
Intermittent Supply or Communication Dropout
Symptom
No power at Siemens EV home charger; display and LEDs are completely off and vehicle does not detect the charger.
No Mains Supply / Internal Fuse Open
Symptom
Plastic around the Type 2 connector on the Siemens charger shows discoloration or slight melting.
Localized Overheating at Connector
Symptom
RFID card reader area on Siemens charger is unresponsive; no beep or LED change when card is presented, but charging still works in plug-and-charge mode.
RFID Reader Hardware Failure
Symptom
Siemens charger does not start charging when scheduled by a smart home system, but works when started manually.
External Control Logic / Integration Fault
Symptom
Siemens charger trips the upstream RCD or breaker immediately when a charging session starts.
Short Circuit or High Leakage at Start-Up
Symptom
Siemens charger’s internal fan runs loudly or continuously, even at low charging currents or when idle.
Cooling Fan Wear or Temperature Sensor Misread
Symptom
Siemens EV charger housing becomes very hot to the touch during normal charging, even at moderate ambient temperatures.
Overheating / Poor Thermal Dissipation
Symptom
Type 2 connector is difficult to insert or remove from the Siemens charger or vehicle inlet.
Mechanical Wear / Misalignment of Connector
Symptom
Vehicle reports ‘charging station locked’ or ‘no response’ and Siemens charger shows normal idle lights but never starts charging (no error code).
Control Pilot Signal Level Incorrect
Symptom
Visible arcing or sparking when plugging in or unplugging the Type 2 connector from the Siemens charger or vehicle.
Contact Wear / Delayed Contactor Operation
Symptom
Water or condensation visible inside the Siemens wallbox window or dripping from the housing.
Moisture Ingress / IP Seal Failure
