E01
Charging session will not start; charger display shows E01 shortly after vehicle is plugged in.
Proximity Pilot (PP) / Cable Recognition Fault
E02
Charger refuses to start charging; display or LED status indicates E02 or pilot error.
Control Pilot (CP) Signal Fault
E03
Charging stops immediately after connection; E03 displayed or red fault LED with pilot error pattern.
Vehicle Communication / PWM Duty Cycle Out of Range
E04
Charger shows E04 and refuses to energize; often logged as insulation or ground fault.
Insulation Monitoring / Ground Fault Detected
E05
Charger displays E05 or overcurrent fault; charging stops shortly after starting.
Overcurrent / Output Overload Protection Trip
E06
Charger shows E06 or contactor fault; unit clicks repeatedly or fails to close the relay.
Main Contactor / Relay Fault
E07
Charger indicates E07 or overtemperature; charging stops after some time, especially in hot weather.
Internal Overtemperature Protection
E08
Charger shows E08 or supply fault; unit will not enable charging and may indicate incorrect mains voltage.
Supply Voltage Out of Range
E09
Charger displays E09 or phase fault; three-phase models may charge at reduced power or not at all.
Phase Loss / Phase Imbalance Detection
E10
Charger shows E10 or earth fault; unit refuses to start charging and may indicate missing PE.
Protective Earth (PE) Fault / High Earth Impedance
E11
Charger indicates E11 or RCD fault; integrated protection cannot be reset.
Residual Current Device (RCD) Trip / Self-Test Failure
E12
Charger shows E12 or lock fault; vehicle cannot be disconnected or charging will not start due to connector lock error.
Connector Locking Mechanism Fault
E13
Charger displays E13 or communication error; smart features (load management, app control) fail and charging may be disabled.
Internal Communication Bus Fault
E14
Charger shows E14 or metering error; energy readings are unavailable or charging is blocked due to metering fault.
Internal Energy Meter Fault
E15
Charger indicates E15 or configuration error; unit may refuse to start charging after installation or reset.
Configuration / Parameter Error
E16
Charger shows E16 or RFID/authentication error; charging is blocked even though power is available.
User Authentication / RFID Reader Fault
E17
Charger displays E17 or load management error; unit may limit current to very low values or block charging.
Dynamic Load Management (DLM) / External Meter Communication Fault
E18
Charger shows E18 or firmware error; unit may reboot repeatedly or remain in fault state.
Firmware Corruption / Boot Failure
E19
Charger indicates E19 or internal memory error; configuration may be lost after power cycles.
Non-Volatile Memory (NVM) Fault
E20
Charger shows E20 or self-test failure at startup; unit does not enter ready state.
Power-On Self-Test (POST) Failure
Symptom
Burning smell or melted plastic odor coming from the charger during or after charging.
Overheating / Component Degradation
Symptom
Charger cable or connector is physically damaged (cracked housing, exposed conductors, bent pins).
Mechanical Damage to Output Cable/Connector
Symptom
Charger cannot connect to Wi‑Fi or Ethernet; smart features and remote monitoring do not work, but basic charging is fine.
Network Connectivity Failure
Symptom
Charger display is on but very dim or flickering; LEDs may pulse irregularly.
Unstable Low-Voltage Supply
Symptom
Charger display or app shows incorrect charging power or energy values compared to vehicle readings.
Inaccurate Energy or Power Measurement
Symptom
Charger does not recognize that the vehicle has been unplugged; status remains 'connected' or 'charging' even with no cable attached.
Stuck Vehicle Presence Detection
Symptom
Charger emits a loud humming or buzzing noise during operation.
Excessive Acoustic Noise from Contactor or Transformer
Symptom
Charger enclosure becomes very hot to the touch during normal charging, though charging continues.
Excessive Thermal Rise Under Load
Symptom
Charger enclosure vibrates noticeably when charging at full power.
Mechanical Vibration Under Load
Symptom
Charger frequently reports 'charging complete' much earlier than expected, even though the vehicle battery is not full.
Premature Charge Termination
Symptom
Charger intermittently stops charging mid-session without any error code; charging resumes if cable is reconnected.
Intermittent Charging Interruption
Symptom
Charger LEDs or display are completely dead; unit appears unpowered even though breaker is on.
No Power / Dead Unit
Symptom
Charger randomly reboots during charging sessions; LEDs go off and then restart, sometimes interrupting charging.
Unexpected Controller Reset
Symptom
Charger trips the upstream circuit breaker or RCD as soon as charging starts, without showing a specific charger error.
External Protection Nuisance Trip
Symptom
Front cover or door of the charger does not close or latch properly, leaving internal parts partially exposed.
Enclosure Latching / Mechanical Integrity Issue
Symptom
RFID card reader area is unresponsive; no beep or LED change when presenting cards, but charger otherwise works in free mode.
Non-Functional RFID Reader
Symptom
Vehicle plugged in but charging does not start; no error code displayed, LEDs remain steady or show 'ready' state.
No Charge Start Without Fault Indication
Symptom
Visible arcing or sparking when connecting or disconnecting the charging connector.
Unsafe Arcing at Connector
Symptom
Water or condensation visible inside the transparent parts of the charger or dripping from the enclosure.
Moisture Ingress / IP Rating Compromise
