E020
Charger shows E020; internal clock or time synchronization error affecting schedules and logs.
Real‑Time Clock (RTC) / Time Sync Fault
Symptom
Charger cannot be discovered by the Alfen app or local commissioning tool over the network.
Local Network Discovery / mDNS Failure
Symptom
Charger display or status LEDs are completely dead; no signs of life when power is applied.
No Power / Dead Unit
Symptom
Charger emits a loud humming or buzzing noise during charging.
Acoustic Noise from Contactor or Magnetic Components
Symptom
Charger housing becomes unusually warm or hot to the touch during normal charging.
Excessive Thermal Load / Localized Overheating
Symptom
Charger intermittently stops charging before the vehicle battery is full; no error code displayed.
Intermittent Charging Dropout
Symptom
Charger trips the upstream RCD or MCB as soon as a charging session starts, but no internal error code is logged.
Nuisance Tripping of Upstream Protection
Symptom
Charger’s clock‑based features (schedules, logs) drift in time even though power is not lost.
RTC Drift Without Network Sync
Symptom
Charger’s enclosure or mounting bracket feels loose or moves when plugging/unplugging the cable.
Mechanical Mounting Instability
Symptom
Charger’s front LED ring or status LEDs show incorrect colors or patterns compared to manual, but charging works.
LED Indicator Control Fault
Symptom
Charger’s internal fan (if fitted) runs constantly at high speed or is very noisy.
Cooling Fan Control or Bearing Wear
Symptom
Display is on but very dim, flickering, or unreadable; charger otherwise appears to function.
Display Module / Backlight Degradation
Symptom
RFID cards are sometimes not detected unless held very close or at a specific angle.
Weak RFID Reader Performance
Symptom
Tethered charging cable insulation shows cracks, discoloration, or stiffness.
Degraded Tethered Cable Insulation
Symptom
Type 2 plug is difficult to insert or remove from the charger socket.
Mechanical Wear or Deformation of Socket Contacts
Symptom
Unusual burning smell or visible scorch marks near the cable entry or terminal block.
Thermal Damage to Terminals or Cable Entry
Symptom
Vehicle plugged in but charging does not start; no error code shown on display or app.
No‑Start Charging Session Without Error Indication
Symptom
Visible water droplets or condensation inside the transparent front cover or on internal components.
