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 El Campello

In El Campello, where seafront villas combine with apartment blocks, EV chargers face an added enemy: the sea breeze. Proximity to the coast accelerates corrosion in connectors, contacts and panels in poorly ventilated garages, and many Wallbox faults we repair here start with an oxidised contact or a Type 2 connector degraded by salt.

We handle charger repairs in El Campello town, Muchavista and the local urbanisations. As well as repairing the unit, we check the weather-tightness of the installation and the state of the protections, because in a marine environment a lasting repair means protecting the points sensitive to moisture.

Repair or replace: when each one makes sense

Salt corrosion often settles this question. If the salt has only attacked the Type 2 connector or a terminal, the repair is straightforward and the unit is as good as new. If it has reached the circuit board, repair stops making sense: the fault comes back, and usually in the least accessible part.

The other factor is spare parts. On chargers over seven or eight years old the manufacturer no longer reliably supplies the board or the power supply, and waiting weeks for an uncertain part rarely pays. We give you both figures before you decide: what the repair costs and what a new unit with its warranty costs.
