Configuration Memory / EEPROM Fault
Symptom
Built-in Type 2 tethered cable on Vestel charger shows cuts, abrasions, or exposed conductors.
Mechanical Cable Damage
Symptom
Charger enclosure becomes unusually hot to the touch during or after a charging session.
Overheating / Poor Thermal Dissipation
Symptom
Charger starts charging but stops intermittently without any error code; vehicle may show 'charging interrupted'.
Intermittent Connection / Control Pilot Instability
Symptom
Type 2 charging cable is difficult to insert or remove from the Vestel charger socket.
Mechanical Wear / Deformation of Socket
Symptom
Vehicle plugged in but charging will not start; no error code shown on Vestel EV charger display.
Basic Start-Up / Authorization Failure
Symptom
Vestel EV charger front panel or enclosure is cracked or physically damaged, but unit may still function.
Mechanical Enclosure Damage
Symptom
Vestel EV charger makes loud humming or buzzing noises during charging.
Acoustic Noise from Contactor / Power Electronics
Symptom
Vestel EV charger powers on but display is blank or unreadable; LEDs may still function.
Display Module / HMI Failure
Symptom
Vestel EV charger trips the house RCD/RCBO whenever a charging session starts.
Earth Leakage / Nuisance Tripping
Symptom
Vestel EV charger’s contactor chatters (rapid on/off clicking) when starting a charge.
Unstable Contactor Control / CP Signal Fluctuation
Symptom
Vestel EV charger’s Ethernet port LEDs are off and no network link is established.
Ethernet Link Failure
Symptom
Vestel EV charger’s front LEDs blink in an unusual pattern and the unit is unresponsive, with no clear error code.
Firmware Lockup / Software Crash
Symptom
Vestel EV charger’s internal clock drifts significantly, causing scheduled charging to start at wrong times.
Clock Drift / Timekeeping Inaccuracy
Symptom
Vestel EV charger’s internal fan runs constantly even when not charging, and the unit is noisy.
Fan Control / Temperature Sensing Anomaly
Symptom
Vestel EV charger’s load management with external CTs appears inaccurate; charging current is reduced even when house load is low.
Incorrect External CT Measurement
Symptom
Vestel EV charger’s RFID reader area is scratched or opaque, making it hard to read cards reliably.
RFID Window / Front Panel Wear
Symptom
Vestel EV charger’s Wi‑Fi signal is weak or unstable, causing app control issues.
Poor Wireless Connectivity
Symptom
Vestel EV home charger completely dead: no LEDs, no display, and no relay click when plugging in vehicle.
No Power / Dead Unit
Symptom
Water or condensation visible inside the Vestel EV charger enclosure; possible corrosion on terminals.
Moisture Ingress / IP Seal Failure
