Symptoms
- Charger's status light shows an error color or is off
- No charging happens when the cable is connected
- Charger worked before and stopped suddenly
- Breaker panel shows a tripped switch
Likely causes
- CommonTripped breakerHome chargers draw significant continuous current and can trip a breaker, especially if other high-draw appliances run at the same time.
- CommonCharger needs a power cycle or resetLike other smart home devices, chargers can occasionally freeze and need a restart.
- PossibleWi-Fi connectivity issue (for smart chargers)Some chargers require an active app connection to authorize charging and can fail if Wi-Fi drops.
- PossibleLoose wiring connection at the charger or panelVibration or age can loosen electrical connections over time.
What to do
- Check your home's breaker panel for a tripped breaker related to the charger circuit and reset it if needed.
- Unplug the charger from power (if it's a plug-in unit) or use its reset procedure, then power it back on.
- Check the charger app or manual for what its status light colors mean.
- For smart chargers, confirm your home Wi-Fi is working and the charger shows as online in its app.
- Try charging with a different EV if you have access to one, to rule out a car-specific issue.
- If the breaker trips repeatedly, stop using that circuit and don't reset it multiple times, since repeated tripping can indicate a wiring fault.
