Start with the status messages
Check the vehicle display, vehicle app, charger indicators, and charger app if one is used. Record the exact message, indicator pattern, and time the problem occurred before restarting anything.
Confirm whether the issue affects every charging attempt or only a particular schedule, vehicle, power level, or time of day. That distinction helps separate settings from equipment faults.
Charging does not start
Make sure the connector is fully seated, the vehicle is in the required parked state, and neither the vehicle nor charger is waiting for a scheduled start time. Check that a charge limit has not already been reached.
If the charger has no power or a breaker has tripped, stop and follow the safety guidance below. Do not repeatedly reset a breaker that trips again.
Charging is slower than expected
Compare the displayed charging power with the charger's configured limit and the vehicle's AC charging limit. Review any reduced-current setting, scheduled charging window, temperature message, or household load-management behavior.
Remember that the wall charger's advertised maximum may exceed what the installed circuit or vehicle can use. Normal losses also make energy reaching the battery lower than energy drawn from the wall.
Charging stops or becomes intermittent
Look for a loose connector, scheduled stop time, reached charge limit, network command, or vehicle notification. If a plug, receptacle, cable, or charger is unusually hot, discolored, damaged, buzzing, or producing an odor, stop using it immediately.
For recurring interruptions, save timestamps and messages and contact the vehicle or charger manufacturer as appropriate. An electrician should inspect suspected circuit or receptacle problems.
The charger is offline
A smart charger's app or Wi-Fi can be offline while basic charging still works. Check the manufacturer's documented network steps, router availability, and whether charging succeeds without app control.
Do not open the charger enclosure to troubleshoot connectivity. If charging itself is unavailable, use the status information to determine whether to contact support or an electrician.
When to stop troubleshooting
Stop using the equipment if a breaker repeatedly trips, any component overheats, there is visible damage, water intrusion, arcing, smoke, unusual odor, or exposed wiring. Keep clear and contact a qualified electrician or emergency services when appropriate.
Never open electrical equipment, alter wiring, bypass protection, or use an improvised adapter to get charging started.
Do not repeatedly reset a tripping breaker: A breaker that trips again is reporting a problem. Leave it off and have the circuit and charging equipment evaluated by a qualified electrician.
Frequently asked questions
Use only the restart procedure documented by the manufacturer. Do not open the enclosure or cycle a repeatedly tripping breaker.
The vehicle, charger, or both may have schedules. Check for overlapping schedules and any utility or load-management settings.
Call an electrician for circuit, breaker, receptacle, wiring, heat, or damage concerns. Contact the charger or vehicle manufacturer when status messages point to that equipment.
