Charger refuses to start; LED ring shows red/amber pattern and app reports E003 – Overcurrent or short circuit.

Safety first: Turn off the main breaker to the charger before inspecting wiring or socket.

• Check upstream protection: Verify the dedicated MCB/RCBO rating matches the NewMotion charger’s configured maximum current (e.g., 16 A or 32 A). Oversized or undersized breakers can cause issues.
• Inspect Type 2 socket: Look inside the vehicle connector socket on the charger for bent pins, foreign objects, or burn marks. Do not insert metal tools into the socket.
• Check cable condition: If using a tethered cable, inspect the full length for cuts, crushing, or melted insulation. Replace the cable if any conductor is exposed.
• Internal wiring check: With power isolated and cover removed, inspect the load-side wiring from the contactor to the socket or tethered cable terminals. Look for signs of shorting to earth or between phases.
• Reset and test: After correcting any visible issues, re-energize the charger and attempt a low-current test charge (if configurable) to see if E003 clears.
• Module replacement: If no external fault is found and E003 persists, the power module current sensor or main PCB may be defective and require replacement.
