Wallbox shows E14; charging stops shortly after start; vehicle may show ‘Overcurrent’ or ‘Charging interrupted’.

Safety first: Overcurrent conditions can overheat wiring. Inspect for signs of overheating before reusing the charger.

• Verify current setting: Check the wallbox configuration (DIP switches, rotary dial, or app) to ensure the maximum current is set to match the circuit rating and cable capacity.
• Inspect cable and plug: Look for softening, discoloration, or deformation of the Type 2 plug or cable, which indicates overheating. Replace if damaged.
• Test with another vehicle: If possible, test charging with a different EV. If E14 only occurs with one vehicle, the vehicle may be requesting or drawing excessive current and should be inspected.
• Current sensor check: Persistent E14 with normal loads may indicate a faulty current transformer (CT) or measurement circuit on the control board. A technician should test and replace the CT or board as needed.
