Tesla Wall Charger Red Light: Quick Overview
Flashing red lights on the Tesla wall charger can be concerning, as they often disable charging. Despite receiving a, “charging equipment not ready”. Notification on the vehicle screen, the Tesla mobile app may not provide any alerts.
Now, the table below will give you a brief insight into what these lights indicate and how to solve them.
| Issue | Charging | Solution | |
| No Light | Disruption in power supply | Charging disabled | Verify power supply, troubleshoot with the electrician, and check voltage readings. |
| Solid Red | Internal fault | Charging disabled | Turn off circuit break, check indicator; contact Tesla with necessary details. |
| Red Light Flashing One time | Ground fault circuit interruption, current path unsafe | Charging disabled | Check components for damage, ensure proper grounding, consult electrician. |
| Red Light Flashing Two Times | Ground assurance fault | Charging disabled | Check ground and bonding, contact manufacturer. |
| Red Light Flashing Three Times | High temperature | Charging limited or disabled | Verify Wi-Fi connection, get electrician for inspection. |
| Red Light Flashing Four Times | Communication loss | Online usage disabled | Check for Wi-Fi interference, router status; update Wi-Fi setting. |
| Red Light Flashing Five Times | Power-sharing communication loss | Charging reduced | Remove Wi-Fi interference, re-link wall connectors. |
| Red Light Flashing Six Times | High voltage, poor grid | Charging disabled | Check power supply voltage, get electrical. |
| Red Light Flashing Seven Times | Oversupply of current to vehicle | Charging disabled | Reduce charge current, contact manufacturer. |
All Types of Red Light flashing
Each series of blinking of Tesla wall charger light means different issues. Learn about each issue and its particular solution.
Red Light with No Flashing
If the Tesla wall charger’s red light stays solid, it may signal an internal fault; if it persists without interruption, consider replacing the wall connector.
Diagnosis and solution: Turn off the circuit breaker for 5 seconds, then switch it back on. If the red light remains solid, replacement may be needed.
Seek help from a certified electrician or contact Tesla support, providing photos of the wall connector’s part and serial numbers, vehicle VIN, time of the issue, and any error code displayed. For direct assistance, call Tesla at (888) 765-2489.
Red Light Flashing 1 Time
A single red flash on the Tesla wall charger indicates a ground fault circuit interrupter’s (GFCI) interruption, signaling an unsafe current path, potentially due to damage or water ingress.
Diagnosis and solution: Check the handle, cable, vehicle charge port, and wall connector for damage and water ingress. Ensure the wall connector’s ground isn’t connected to an electrical wire. If unsure, seek an electrician’s help. For further troubleshooting tips, explore our guide on Tesla charge port latch issues.

Red Light Flashing 2 Times
If the red light flashes twice, it means there’s a ground assurance fault. This means that there’s an issue with how the charger is connected to the ground.
Diagnosis and solution: To fix the issue, secure all connections and check the ground and neutral at the main panel. Consider an electrician, especially for transformer-linked connectors.
Red Light Flashes 3 Times
If the Tesla wall charger flashes a red light three times, it means that a high temperature was detected. This can happen due to overload, faulty components or wire connections, poor ventilation, etc. If you notice smoke emanating from your Tesla during charging, we recommend referring to our comprehensive guide on potential causes. This resource will help you determine whether the issue is cause for concern or not.
Diagnosis and solution: Update firmware for precise temperature monitoring. If cable and faceplate heat up, have an electrician inspect conductors and terminal boxes. For additional support, reach out to Tesla.
Red Light Flashes 4 Times
Four flashes of the red light indicate an internet connection disruption, possibly due to router failure, weak Wi-Fi signal, or password changes without updates.
Diagnosis and solution: To fix this, check your Wi-Fi router’s functionality and update your mobile device’s Wi-Fi settings if you changed the password recently.
Red Light Flashing 5 Times
Similar to the four-times blinking issue, if you see the red light blinking four times, it indicates poor communication or power-sharing with the connector, resulting in reduced charging.
Diagnosis and Solution: you need to check if the Wi-Fi router is okay or if its signal is being disrupted. Then, follow the commissioning procedure for re-connecting the wall charger to Wi-Fi.
Red Light Flashing 6 Times
This sign usually means two things. Either there’s over-voltage, or the grid quality is bad.
Diagnosis and solution: To ensure the power supply is correct (200–240 volts), use a multimeter to measure voltage. This involves disconnecting the wall charger from the wire box, a task best handled by an electrician due to potential risks.
Measure voltages: L1 to Ground, L2/N to Ground, L1 to L2/N, and L1.
Red Light Flashing 7 Times
When you see Tesla wall charger red light flashing for seven times, it indicates to over supply of current. This error occurs when the vehicle gets high amount of electricity.
Diagnosis and solution: Lower car’s charging. Contact Tesla with details for persistent issues; for non-Tesla vehicles, contact manufacturer. Red blink codes repeat after pause.
Reset

After resolving the issue, error messages on the car screen may persist, which can be cleared by resetting the wall connector. To reset without rebooting, remove the cover to access the reset button on the right side, then press it for 2 to 3 seconds until the top lights turn green from red.
Alternatively, for a full reboot, press the reset button for 5 seconds until the top light turns green; if the error persists, seek assistance from Tesla or an electrician.
