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 Calpe

In Calpe, dominated by the Peñón de Ifach, many EV chargers are in the communal garages of the large seafront buildings, a situation similar to Benidorm's towers. The height of the blocks means long runs and voltage drops the charger can read as a fault, and shared RCDs that trip when several neighbours charge at once.

We repair chargers in Calpe, serving a German, British and Belgian clientele in their language, both in high-rise apartments and in the villas of the inland estates. We check the cable section, the voltage drop and the space's RCD, and reinforce the line when the distance from the meter demands it.

When the fault only shows at certain hours

It is the classic pattern in the garages of the Calpe towers: the charger works in the morning and fails from eight in the evening. It is neither coincidence nor the unit. At that hour several neighbours are charging at once, along with the lifts and the communal lighting, and the voltage at the end of a long run falls below what the charger will accept.

That diagnosis cannot be made on a midday visit. We leave a voltage logger running for several days to see the real curve and, with that figure, the answer is usually dynamic load management sharing the available power between the points, instead of each one drawing what it can until none of them work.
