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 Ciudad Quesada

In Ciudad Quesada, one of the Vega Baja estates with the largest British population, almost every home is a villa with a pool, and EV chargers coexist with the filtration and outdoor lighting installation. Many faults we repair here mix both worlds: poor earthing that affects both the charger and the pool's safety at once.

We repair chargers in Quesada and La Marquesa, serving the large British community in English with clear quotes and punctual appointments. We diagnose the unit, the EV-specific RCD and the villa's earthing, which on these plots is the most frequent cause of a Wallbox turning red.

One fault, two installations: charger and pool

In Quesada and La Marquesa almost every villa has a pool, and its filtration pump, underwater lighting and the charger frequently share the same earth. When that earth is poor, the visible symptom is the charger cutting the charge, but the real risk sits at the other end: the electrical safety of the pool itself.

So when the diagnosis points at the earthing, we also check the equipotential bonding of the pool's metal elements. It is a short check that makes use of the visit already being made, and more than once it has resolved the charger fault and uncovered a far more serious problem nobody suspected.
