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 San Vicente del Raspeig

In San Vicente del Raspeig, a university and residential town next to Alicante, charger installation in detached and terraced houses with their own garage is growing fast. Most faults we repair here are from domestic chargers: RCDs tripping when charging starts, communication errors with the car or current settings incompatible with the home's contracted power.

We provide charger repair throughout San Vicente del Raspeig, including the university area and residential neighbourhoods. As it is a domestic charger, we usually diagnose and repair in the same visit, leaving a full charge test before finishing to ensure the problem is resolved at the root.

When the problem is not the charger but the house

A good share of the calls we attend in San Vicente end without touching the charger. The unit works; what fails is the installation behind it: a line shared with another circuit to save on labour, a panel with no room for the dedicated protection, or a contracted power that cannot cope with charging while the air conditioning runs.

That is why the diagnosis starts at the panel, not at the wallbox. We measure the voltage drop on the line with the car charging, check the protection is the correct one and review what else hangs off the same circuit. Correcting that resolves the symptom for good; changing the charger does not.
