Symptom
Charger completely dead: no LEDs, no display, and no relay click when power is applied.
No Power / Dead Unit
Symptom
Charger enclosure feels very hot to the touch during or after charging, even in moderate ambient temperature.
Excessive Internal Heating
Symptom
Charger makes loud buzzing, humming, or clicking noises during operation.
Abnormal Acoustic Noise from Contactor or Power Electronics
Symptom
Charger powers on but will not start charging; vehicle shows 'charging station error' with no code on charger.
General Charging Refusal / Handshake Failure
Symptom
Charger randomly reboots during charging or idle, with all lights cycling off and on.
Unexpected Reset / Power Interruption
Symptom
Charger starts charging but stops after a few minutes without any error code; LEDs may show normal state.
Intermittent Charging / Session Dropout
Symptom
Charger trips the house RCD/GFCI or main breaker as soon as charging starts.
Nuisance Tripping / High Leakage or Short Circuit
Symptom
Charger’s cable insulation is nicked, cut, or shows signs of abrasion.
Damaged Output Cable Insulation
Symptom
Charger’s cable or connector becomes excessively hot during charging, sometimes with a plastic smell.
Overheating Connector / High Contact Resistance
Symptom
Charger’s connector will not latch properly into the vehicle inlet or is difficult to insert/remove.
Mechanical Latch / Connector Wear
Symptom
Charger’s display is very dim, flickers, or has missing segments, but charging still works.
