ALEX HARPER

It is a hallmark of Tesla vehicles that they are environmentally friendly, luxurious, and fashionable. The Tesla Model 3, X, Y, and S are among the most popular electric vehicles. Although it is common for cars to be charged at home, this may not always be the case. Don’t panic! There’s no need to panic! A little patience, some knowledge, and maybe some assistance are all you need to get your Tesla charging working correctly. We will address this problem in this article using these reasons and solutions.

Tesla Wall Charger Not Working

What’s wrong with my Tesla wall charger? The causes are as follows:

Our problems include the following:

1. The wall charger no longer functions

A loss of charging communication can cause power source issues. Your touchscreen will display error codes CP_a046, CP_a053, and CP_a055. 

2. Charger not found by Tesla vehicle

When Teslas have sensor-related problems, they are not charging from the wall plug at home. A CP_a043 warning appears when a charger is not properly seated.

4. Tripped circuit

In addition, the charger could have tripped and shut down automatically. You need to know which circuit powers your car’s Level 1 charger.

5. Unsecure connections to outlets

There might be an issue with the power supply. Connect the charger to the electrical outlet all the way. Plug it back in only after it has been completely removed from the wall. In the event of a damaged outlet, contact an electrician immediately. Try turning off the breaker if it is connected to that outlet. There is a risk of disaster if you take any chances.

6. Software problems

Upgrades to wall connections can sometimes cause issues. It is essential to update your firmware. You will see a message indicating that the update was successful when it has been completed.

After that, the program will automatically restart. Also, the cable connecting the car to the charging station can be faulty.

7. Charging takes a long time

There is a possibility that your circuit breaker has a maximum output, which may explain the slow charging from your wall charger. It is possible that your Tesla won’t have enough power with the most common circuit breaker output.

8. Check the Wi-Fi settings

Wi-Fi is used for updating and upgrading Tesla devices. This is why it is necessary to keep the Tesla charger plugged in at all times. Make sure your Wi-Fi connection works by testing other apps on your phone. It is possible for faulty routers or incorrect Wi-Fi settings to cause faulty Wi-Fi connections.

9. Current weather conditions

Tesla cars’ charging can also be affected by the climate. In addition to temperature, humidity, and rainfall, there is the weather outside the car and charger.  The weather outside can be hot or cold. As a result, the battery system and charger can be less effective, and this can affect a driver’s and passenger’s safety and comfort.

There are three ways to fix a broken Tesla wall charger:

You can solve this problem by following these solutions:

1. Find a solution to the voltage problem

A tight connection must be made between the breaker box and each connection. As soon as the plug is connected to the wall outlet, you will need to ensure that the voltage is not low and that the connection between L1 and ground, L2 to ground, and L1 to L2 is not faulty, regardless of how much power Tesla is using. There is also a need to cover the connectors on the wall as well as the beaker. A wall connector should be reinstalled if it has been dropped and the cover of the breaker has been damaged. There is also a need to turn off the breaker as well. 

After you have clicked the Tesla plug button, continue to push the button until the connection has been completed. You will now see different types of green lights depending upon the number of circuits and the number of circuit breakers (5-green for 60A, 4-green for 50A). As soon as it begins, a flashing blue light will alert you. When the Tesla is not set up according to the light numbers, you will be required to enter the Wi-Fi SSID. There will be a need to enter the Wi-Fi SSID as well if it is not configured according to the light numbers. Following the connection of the cable and insertion of the Tesla, the Tesla needs to be inspected. It is possible to reset the device if the problem persists by pressing the Reset button on the toolbar.

2. Resolve connection issues

When you remove the wall connector from your Tesla, you may need to reattach it if it doesn’t work. Turning off the circuit breaker should be followed by turning it off for a minimum of ten seconds. By turning the Tesla on, connect the wall connection. If you have not been able to connect the Tesla to the charger, you may wish to try using a different wall socket or mobile connector. Replace the device if it does not function.

3. Problem with the software

For more information about the wall connector, please click here. You can download the firmware by clicking “Firmware 22.41.2.”. Wi-Fi should be enabled on the Tesla wall charger before downloading the firmware. Wall connections are necessary for Wi-Fi routers. Select the firmware from the list and click “Choose file”. You can update the firmware by entering https://192.168.92.1/update or https://192.168.92.1/service/update . To upload the firmware, click “Choose file” and wait. Your device will show a successful update message once the update has been completed. Automatic restart will follow restoration of wall connection.
