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 Torrevieja

In Torrevieja, with one of the largest foreign-resident communities on the Costa Blanca, EV chargers sit alongside 1980s and 1990s urbanisation installations that were not always ready for charging. Many faults we diagnose here come from connecting a Wallbox to an old installation without proper earthing, which causes the classic earth-fault and red light.

We repair chargers both in the villas of Torrevieja's urbanisations and in flats in the centre and La Mata. As we serve many British, German and Scandinavian owners, we clearly explain the cause of the fault and the quote before acting, and put in writing what was repaired so it is on record for the installation.

Chargers in Torrevieja's older urbanisations

Torrevieja's housing stock includes many urbanisations with decades-old electrical installations. Before declaring the Wallbox faulty, we check the earthing and the state of the panel, because a modern charger demands conditions those installations sometimes do not meet.

When we find the real cause is the existing installation, we explain it with a separate quote: repairing the charger without fixing the earth would only make the fault return.
