Wallbox support runs through the Wallbox app and the support section of the Wallbox website, where a case is opened for your region; our data holds no phone number or email for the company. Have the charger serial number, the purchase invoice and the installer's certificate ready, along with the fault code or LED color the unit is showing, because the first question is always which unit and which installation.

Wallbox is a Spanish manufacturer that sells through installers and retailers across Europe and North America, so the installer or the seller is often the faster route for a physical fault. Raise it with both at the same time rather than waiting for one to answer.

Start by reading the fault the unit is reporting: a Wallbox charger signals its status through the LED color and a code in the app, and that code separates a charger fault from a supply fault or a problem in the car. Check whether the breaker or the earth leakage protection in your consumer unit has tripped, then try the car on a public charge point and, if you can, another vehicle on your Wallbox. That tells you which of the three is at fault before you open a case.

Note the date, time and code of every failure, and whether it followed a firmware update, since updates are a common trigger for a unit that worked fine the week before. Anything behind the wall belongs to the installer, not the manufacturer: they certified the installation and they are the ones who can test the supply.

A Wallbox warranty claim needs three things together: the serial number of the unit, the purchase invoice and the installer's certificate for the installation. Open the case through the Wallbox app or support site and attach a dated log of the faults, with codes and photographs of the display or LED. Keep the original packaging if the unit has to go back.

Do not stop at the manufacturer. In the EU and the UK the seller you bought from carries its own legal obligation for faulty goods, separate from the manufacturer warranty, so raise the same claim with the retailer or installer in parallel and say in writing that you are doing so. Being passed in circles between the three of them? A complaint filed through our complaint process breaks that loop: we bring your case to Wallbox through our own channels while other owners can find it.

Connection trouble on a Wallbox is usually the home network rather than the charger. Many home chargers join only a 2.4 GHz network, so a combined 2.4 and 5 GHz network under one name, or a mesh system that moves the charger between bands, is a frequent cause. Check the signal where the unit is mounted, since a garage wall or a meter cupboard cuts it more than people expect, and re-pair over Bluetooth from beside the charger.

When the connection drops, scheduling, tariff matching and monitoring stop working even though the unit usually still charges when you plug in. Record how long the outages last and what the app showed: an intermittent connectivity fault is only taken seriously when it is written down as a pattern with dates. Put that log in your complaint here and our trained AI opens a case file and keeps advising you on what the installer needs from you, what Wallbox needs, and when to push each of them again.

So far consumers reported 2 complaints about Wallbox here, too few to show a clear pattern yet. Our research shows what typically goes wrong at home EV charger makers: units that stop charging or throw a fault after a firmware update, app and wifi connections that drop so scheduling and monitoring stop working, warranty claims that stall while manufacturer, installer and retailer point at each other, spare parts and replacement units that take weeks to arrive, and smart features such as tariff scheduling or solar matching that behave differently than the buyer expected.
