Even reliable equipment can occasionally encounter problems. Knowing how to perform basic troubleshooting on your Electric Vehicle Charger can resolve minor issues quickly and determine when to call a professional.

Start with the simplest checks. If the charger appears dead (no lights), verify that the circuit breaker in your main electrical panel has not tripped. If it has, reset it. If it trips again immediately, do not continue resetting it; this indicates a fault and requires an electrician. Ensure all plugs (if it’s a plug-in unit) are fully seated. For smart chargers, check your home Wi-Fi connection, as a loss of connectivity might cause the unit to behave unexpectedly—a router reboot can sometimes help.

If the charger has power but won’t charge your car, inspect the connector and your vehicle’s charging port. Ensure they are clean, dry, and free of debris. Try firmly re-seating the connector until you hear a definitive click. Check your vehicle’s dashboard or app for any charging error messages; the problem may be a setting in the car (like a charge timer or maximum charge limit set to a low percentage). Consult your vehicle’s manual.

For error lights or specific fault codes, always refer to the manual for your specific Electric Vehicle Charger model. The meaning of flashing red or amber lights varies by manufacturer. A common issue is a ground fault error, which could indicate a problem with the home’s wiring, a faulty charger, or moisture in the connector. If basic steps—power cycling the charger, checking connections, verifying vehicle settings—do not resolve the issue, stop using the Electric Vehicle Charger. The next step is to contact the manufacturer’s support or your installing electrician. Never attempt to open or repair the Electric Vehicle Charger unit yourself, as it contains high-voltage components.
