E01
Charger will not start charging; app or LED status shows error E01 immediately after plugging in the vehicle.
Input Supply Undervoltage
E02
Charging session stops or will not start; display/app shows E02 indicating overvoltage on the supply.
Input Supply Overvoltage
E03
Charger reports E03 and refuses to start charging; often logged as phase failure or phase imbalance in the app.
Phase Loss or Phase Imbalance
E04
Charging stops and E04 is displayed; often associated with overcurrent or internal overtemperature protection.

Overtemperature Shutdown
E19
Charger shows E19; app may indicate vehicle communication error or EV not responding.
EV Communication / State Detection Fault
E20
Charger indicates E20; app may describe it as internal power supply error.
Low-Voltage Power Supply Failure
Symptom
Charger completely dead: no LEDs, no Wi-Fi, no response when breaker is turned on.
No Power / Dead Unit
Symptom
Charger does not respond to load management signals from an external energy meter or home energy management system, but no explicit error is shown.
Non-Functional Dynamic Load Management
Symptom
Charger emits a loud humming or buzzing noise during charging.
Excessive Acoustic Noise from Power Components
Symptom
Charger frequently disconnects from the go-e cloud or app shows it as offline, while local charging still works.
Cloud Connectivity / Backend Communication Issues
Symptom
Charger housing becomes very hot to the touch during normal charging, even at moderate current.
Excessive Thermal Stress / Overheating Housing
Symptom
Charger intermittently stops charging without any error code; session resumes after unplugging and reconnecting.
Intermittent Charging Dropout
Symptom
Charger powers on but vehicle does not start charging; LEDs show ready state with no explicit error code.
No Charge Start Without Error Code
Symptom
Charger trips the upstream RCD/RCBO as soon as a charging session starts.
Nuisance RCD Tripping During Charge
Symptom
Charger’s enclosure or mounting bracket is loose, causing vibration or movement when plugging/unplugging.
Mechanical Mounting Instability
Symptom
Charger’s front LEDs or display segments are partially not working or very dim, but charging still functions.
LED / Display Segment Failure
Symptom
Charger’s internal energy metering is clearly inaccurate compared to an external meter (e.g., large kWh discrepancy).
Inaccurate Internal Energy Metering
Symptom
Charger’s internal fan (if equipped) is noisy, rattling, or not spinning, leading to higher internal temperatures.
Cooling Fan Failure
Symptom
Charger’s LEDs or display flicker or reset when a vehicle is plugged in or charging current increases.
Voltage Sag / Internal Power Instability Under Load
Symptom
Charger’s Type 2 socket or cable end shows signs of melting, discoloration, or burnt smell.
Overheated Type 2 Connector
Symptom
Charger’s Wi-Fi signal is very weak or frequently disconnects, but charging continues.
Poor Wireless Connectivity
Symptom
Plastic housing of the charger is cracked or damaged, but the unit still operates.
Damaged Enclosure / Reduced IP Protection
Symptom
RFID cards are not recognized; no beep or LED indication when a card is presented, but no RFID error code is shown.
Non-Responsive RFID Reader
Symptom
Visible arcing or sparking when plugging or unplugging the Type 2 connector from the vehicle.
Arcing at Vehicle Connector
Symptom
Water or condensation visible inside the go-e Charger housing or behind the front cover.
