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 Dénia

In Dénia, capital of the Marina Alta, EV chargers are spread between the year-round lively urban centre, the apartments of the Les Marines beaches and the villas of the Montgó estates. This variety means we repair everything from domestic chargers in centre flats to high-end units integrated with solar in mountain villas.

We repair chargers across all of Dénia and its municipality, working in Spanish, English and other languages. We diagnose the unit, the EV RCD and the existing installation with instruments, and when the charger coexists with solar self-consumption we also review the coordination between systems so charging uses the cheapest energy.

What is fixed on site and what needs a part

More is resolved on the first visit than people expect. Oxidised contacts, a worn Type 2 connector, an unsuitable RCD, a current setting that does not match the contracted power, or a unit locked out after a supply cut are all faults closed the same day with the materials we carry.

What needs a part, and therefore a second visit, are circuit board, power supply and internal contactor failures. In Dénia and its municipality, with Montgó villas some way from the centre, this matters: which is why we diagnose with instruments on the first visit and order the part with the model and serial number confirmed, not from memory.
