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 Benidorm

In Benidorm most EV chargers are installed in the communal garages of the Levante, Poniente and Rincón de Loix towers, and that shapes the faults: long runs from the meter to the space, voltage drops and shared RCDs that trip when several neighbours charge at once. When a Wallbox in a Benidorm holiday flat turns red, the cause is usually in both the unit and the building's common installation.

We handle charger repairs in Benidorm's high-rises with the particularity that many spaces are holiday rentals, so we prioritise getting the point working again quickly to avoid losing bookings. We measure the line, check the EV-specific RCD and verify the current configuration, which in these towers is often mis-set against the real available power.

Wallbox faults in Benidorm's towers

The height of Benidorm's buildings means very long cable runs from the meter centralisation to the space, which causes voltage drops the charger reads as a fault. In these cases changing the unit is not enough: the cable section must be reviewed and, sometimes, the line reinforced.

It is also common for the space's RCD to be a type unsuitable for charging; we replace it with an A-EV or B type depending on the charger, leaving the installation compliant and free of nuisance trips.
