The charger shows E006; the contactor does not close and no charging current flows.

Safety first: Always isolate the charger at the main breaker before opening the enclosure. Verify the absence of voltage with a meter.

• Step 1 – Listen for the contactor: When a charging session is initiated, you should normally hear a click from the contactor. If not, suspect a drive or coil issue.
• Step 2 – Visual inspection: With power OFF, open the charger and locate the main power contactor. Check for burn marks, melted plastic, or mechanical damage.
• Step 3 – Check wiring: Verify that the control wires from the main PCB to the contactor coil are firmly connected. Look for broken conductors or loose push-on terminals.
• Step 4 – Coil resistance test: With the charger isolated, measure the resistance of the contactor coil using a multimeter. Compare this with the value specified by the contactor manufacturer. An open circuit indicates a failed coil.
• Step 5 – PCB output check: A technician can measure the control voltage at the PCB output during a start command. If no voltage is present and the coil is good, the PCB driver is likely faulty.
• When to call a technician: Replacement of the contactor or the main PCB should be performed by a qualified EVSE technician.
