Why does my Wallbox charger show a red light?

A red light usually means an earth fault, a communication error with the car, overheating or a tripped RCD. We diagnose the exact cause and repair on site where possible.

How much does EV charger repair cost in Alicante?

The diagnostic visit starts from €80 and is deducted if the repair goes ahead. The final cost depends on whether the fault is in the wiring, the Wallbox or the RCD.

EV Charger Repair in Playa San Juan

In Playa de San Juan, residential blocks and modern developments dominate, where EV chargers are usually in garages with recent pre-installation. Here the most frequent faults are not from old works, but from configuration: badly parametrised chargers, communication errors after a firmware update, or RCDs tripping from a poorly set load-sharing between several spaces.

We repair chargers in the buildings of Playa de San Juan and the Albufereta area with the advantage of being close to Alicante city, which allows short response times. We check the charger app, the dynamic power configuration and the state of the Type 2 connector, which in heavy-use areas wears out sooner than expected.

Repairs in a communal garage: access and permissions

In the Playa de San Juan blocks the charger is rarely on its own: it shares the garage, the panel and sometimes the meter with the rest of the building. To diagnose it we need access to the meter room, and that is arranged with the president or the managing agent before the visit so the trip is not wasted.

We organise the work so the garage stays passable while we are there, and if the line has to be switched off we give the affected neighbours notice in advance. When we finish we hand over a written record of what was measured and what was replaced, a document the association usually asks for.
