Symptom
Charger causes noticeable lights dimming or flicker in the house when charging starts or stops.
Inrush Current / Voltage Sag on Supply
Symptom
Charger completely dead – no LEDs, no display, no relay click when vehicle is connected.
No Power / Dead Unit
Symptom
Charger emits a high‑pitched whining noise even when not charging.
Switch-Mode Power Supply (SMPS) Acoustic Noise
Symptom
Charger intermittently stops charging mid-session without any error code; charging resumes after unplugging and reconnecting.
Intermittent Output Drop / Session Interruption
Symptom
Charger makes a loud buzzing or chattering noise from inside the unit during charging.
Noisy Contactor / Coil Chatter
Symptom
Charger or cable becomes unusually hot to the touch during normal charging, but no error is displayed.
Overheating of Cable or Internal Connections
Symptom
Charger powers on but will not start charging; vehicle shows ‘Charging not possible’ with no error code on charger.
General Start-Up Failure Without Code
Symptom
Charger trips the upstream RCD/RCBO as soon as a charging session starts, but no specific error appears on the charger.
External RCD Nuisance Tripping
Symptom
Charger’s front cover or housing is cracked, loose, or rattling, but the unit still operates.
Mechanical Housing Damage / Enclosure Integrity Compromised
Symptom
Charger’s front LEDs or display backlight flicker or dim randomly during operation.
Unstable Low-Voltage Supply / HMI Power Issue
Symptom
Charger’s internal fan (if fitted) runs loudly or continuously, even at low load or when idle.
Cooling Fan Overrun / Bearing Wear
Symptom
Charger’s scheduled charging or smart tariff features do not start charging at the programmed times.
Scheduling / Timer Function Maloperation
Symptom
Charger’s Type 2 connector will not fully insert into the vehicle inlet or feels unusually tight.
Mechanical Connector Fitment Issue
Symptom
Charger’s Wi‑Fi connection is unstable or frequently drops, causing remote control and monitoring to fail.
Wireless Connectivity Instability
Symptom
RFID cards or tags are not recognized; charger stays locked even with known-good cards.
Access Control / RFID Recognition Failure
Symptom
Unusual burning smell from the Jaguar wallbox during or after charging, even if it still appears to work.
Overheating / Component Degradation
Symptom
Vehicle reports ‘Charging cable locked’ or ‘Unable to release cable’ after charging; charger appears idle.
Connector Stuck / Mechanical Lock Not Releasing
Symptom
Visible water or condensation inside the transparent parts of the Jaguar wallbox; occasional nuisance tripping or errors in wet weather.
Moisture Ingress / Compromised Enclosure Sealing
