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 Guardamar del Segura

In Guardamar del Segura, where many homes are in pine-and-dune estates such as El Raso, EV chargers face the humidity of the riverside setting and the sand, which accelerate the deterioration of contacts and connections. Many of the faults we repair here appear after a season with the home closed, when the unit has locked up or a contact has oxidised.

We repair chargers in Guardamar town and its estates, checking both the unit and the existing installation and earthing, especially important on sandy plots. We advise on how to leave the charger when the home will be unused for a season to avoid the typical restart fault.

Sealing: where the damp actually gets in

The ingress protection rating on the charger's label only holds if the installation respects its conditions, and in El Raso and the estates among the pines that shows. Damp almost never gets in through the housing: it gets in through a loosely tightened cable gland, an unsealed fixing hole or a lid seal aged by the sun.

When repairing, we check those three points, not just the fault that has appeared. We also look at the unit's orientation: a charger mounted on a wall exposed to the easterly wind with no overhang takes horizontal rain and sand several times a year, and sometimes the cheapest solution is a small canopy.
