This problem can occur due to high temperatures. In California, where Tesla is based, the hot weather can be a factor behind this problem. In the UK, however, the weather is less likely to be an issue but it is something to keep in mind on those occasional hot summer days. If you are experiencing one of these rare days, please leave the charger alone for a few minutes in order to allow the charger to cool down.

A high-temperature warning can also occur if the charger has been installed incorrectly. To check if this is the case, feel the faceplate of the charger and the handle of the charging gun for excessive warmth. If you do feel excessive warmth in these areas please leave the charge point alone and contact Tesla.

The four blinking red lines on the charger signify that your charger is having problems connecting to your WiFi network. Firstly, please check to see if your WiFi router is fully operational and connected to the internet.

If you have changed the password on your router recently you’ll need to update your charger with the new details. You can do this by following the instructions in the “check that the Tesla Wall Connector is connected to WiFi” section above.

If your router is fully connected and working but you are still experiencing problems with your charger connecting to it then your issue might be to do with signal strength in the area of your charger. We do ask customers to check the signal strength at the charger location before install but it’s also good practice to check the signal strength afterward too if you’re experiencing connectivity issues, especially if you’ve recently moved your router.

You can do this by bringing any WiFi enabled mobile device to the area where the charger is installed and checking the number of bars on the signal strength indicator (usually located on the top right corner of the screen if using a smartphone).

If you’re experiencing this problem even after resetting the circuit breaker, then you’ll need to contact Tesla as there might be a hardware fault.

If none of the advice above works then you might need to contact Tesla via:

• Clicking here to visit their customer service page (you will need to sign into your Tesla account)
• Calling: 0800 756 9960

Customers should receive their Tesla Wall Connector charger before installation day. It’s good to check the contents inside the box to make sure there isn’t any damage and to check the correct product has been sent.

In the box you should see:

Once the Tesla Wall Charger is in your hands and you've checked that everything that should be in the box is in the box, let us know it has arrived safely. You do this by clicking on the “My Charger Has Arrived” button in the email we sent you. This is important and lets our system know we are one step closer to booking your installation. Knowing you have the correct charger also means we can book you in for installation and allows us to resolve any issues (if there are any) before installation day.

Unlike previous generations of the Wall Connector, the new third-generation now requires a WiFi connection with your home router to work. This is because Tesla will be releasing updates for the charge point.

To connect the Tesla Wall Connector to the customer's home WiFi:

1. Turn on the wall charger via the circuit switch. If everything is operational, the Wall Connector should display a line of green LEDs for 10 seconds
2. Using a WiFi enabled device such as a smartphone or tablet, you can either: 
   • scan the QR code found on the front of the quick start guide; or 
   • stand near the wall connector, open the WiFi settings on your chosen device and connect to the Wall Connector (the WiFi signal name should be “TeslaWallConnector_” followed by a six-digit code). The password is located on the front of the quick start guide under “WPA2”.
3. Once connected scan the QR code below (this can also be found inside the QuickStart guide). If you are using a laptop or a device that does not have a camera, then type the following into the devices’ web browser: http://192.168.92.1
4. If successful you’ll see the unit information followed by four boxes. Tap/click the box that says “WiFi”
5. Select the customer's home WiFi from the list of options and enter your password when prompted
6. If entered correctly you’ll be moved to the connection editing screen. Here you can edit the connectivity information such as the password or WiFi name if you need to.
7. Tap/click “back” when finished
8. Under "WiFi" in the menu, you should see a green dot with the word “connected” next to it.
