The Wallbox chargers are designed to provide a seamless charging experience, but occasionally, error codes may appear in the app. These codes indicate specific issues with your charger or its connection. This article explains each error code and provides step-by-step instructions for resolving them.<\/p>\n

Please note that a certified electrician should only perform advanced troubleshooting steps to ensure safety and compliance with technical standards.<\/p>\n

Ensure the charger’s software is always up to date<\/strong> before going through any troubleshooting steps!<\/p>\n

101<\/strong><\/td>\nThe charger is not functioning correctly due to a connection or internal error.<\/td>\n1. Disconnect the vehicle and restart the charger<\/a>.
2. Reconnect the vehicle after restarting.<\/td>\n		1. If the issue persists, restore the charger via the Wallbox app<\/a>.<\/td>\nUser<\/td>\n<\/tr>\n
102<\/strong><\/td>\nThe charger has detected that one of its internal relays is stuck in a closed position when it should be open.<\/td>\n1. Disconnect the vehicle.
2. Perform a power cycle at the circuit breaker.
3. Once restarted, connect the vehicle.
4. Restore the charger<\/a>.<\/td>\n		\u00a0<\/td>\nUser<\/td>\n<\/tr>\n
103<\/strong><\/td>\nThe charger has detected a direct current (DC) leak, which could originate from the vehicle\u2019s onboard charger (OBC), the charger itself, or the electrical installation.<\/td>\n1. Disconnect the vehicle and restart the charger<\/a>.
2. Reconnect the vehicle.<\/td>\n		1. If the issue persists, restore the charger via the Wallbox app<\/a>.<\/td>\nUser<\/td>\n<\/tr>\n
104<\/strong><\/td>\nThe charger has detected an issue with the control pilot (vehicle communication) circuit.<\/td>\n1. Switch off the charger and unplug the vehicle.
2. Restart the charger<\/a> and try charging again.<\/td>\n		1. If the issue persists, restore the charger via the Wallbox app<\/a>.<\/td>\nUser<\/td>\n<\/tr>\n
106<\/strong><\/td>\nThe charger has detected an unexpected voltage on the control pilot (CP) signal, which does not align with the standard ranges.<\/td>\n1. Switch off the charger and unplug the vehicle.
2. Restart the charger<\/a> and try charging again.<\/td>\n		1. If the issue persists, restore the charger via the Wallbox app<\/a>.<\/td>\nUser<\/td>\n<\/tr>\n
107<\/strong><\/td>\nThe charger was unable to lock the EV gun properly, which could be due to incorrect insertion.<\/td>\n1. Connect the cable to the vehicle (not the charger).
2. Now connect the cable to the charger, ensuring it is entirely in the socket.
2. You will see that the cable is fully inserted when there’s a change in the charger LEDs (from white to green or bouncing green, depending on the model).
3. <\/span>Perform a power cycle or\u00a0restart the charger;\u00a0after doing a power cycle, there is a 30-second window frame to release the EV gun, which is locked again after that.
4. If the cable is still blocked, Push the cable further into the socket. After the charging session, disconnect the hose from the car.
Unlock the charger using the app<\/a> and remove the cable (push forward, rotate around the axle or push a bit up).<\/td>\n		1. Repeat all the steps if needed.<\/td>\nUser<\/td>\n<\/tr>\n
109<\/strong><\/td>\nThe charger has detected that the voltage between L1 and N is outside the acceptable limits defined by UK regulations, preventing it from operating.<\/td>\n1. If the grid voltage stabilizes, the charger will clear the error automatically.
2. If the error persists, power off the charger and unplug the vehicle. Power on the charger and try charging again.<\/td>\n		(CERTIFIED ELECTRICIAN ONLY)<\/strong> 1. If the error persists, check the voltage between L1 and N. Contact the electrical provider if the voltage is outside the 210-254 V range.<\/td>\nUser\/Certified Electrician<\/td>\n<\/tr>\n
110<\/strong><\/td>\nThe charger can not properly read the charging cable resistor.<\/td>\n1. Disconnect the EV gun from the charger, wait for the LED to turn white and reconnect it making sure the it is fully inserted into the charger.<\/td>\n1. If the error persists, try a different charging cable.
2. If the issue persists, restore the charger via the Wallbox app<\/a>.<\/td>\n		User<\/td>\n<\/tr>\n
112<\/strong><\/td>\nThe charger has measured a voltage between L1 and Neutral that is lower than 150V, which is below the acceptable threshold.<\/td>\n1. If the grid voltage stabilizes, the charger will clear the error automatically.
2. If the error persists, power off the charger and unplug the vehicle. Power on the charger and try charging again.<\/td>\n		1. If the error persists, power off the charger and unplug the vehicle. Power on the charger and try charging again.
2. If the issue persists, restore the charger via the Wallbox app.
