What does Red halo (solid) mean?

A solid red halo indicates a general error involving the charger, the connected vehicle or the electrical supply, and charging cannot proceed. Because the red state covers several underlying conditions, the charger app usually narrows it down to a numeric code.

Which models use this code?

Verified for

Wallbox — Pulsar Plus

Most likely causes

Charger, vehicle or supply error

Manufacturer documented

The three possible domains of a general error are the unit itself, the vehicle, or the electrical supply.

Damaged or contaminated charging cable

Possible

Cable and connector damage is a common trigger for protective errors.

Outdated charger software

Possible

Some error states are corrected by a firmware update.

Safe checks you can perform

1
Disconnect and inspect the cable
Look for cuts, crushed sections, scorching or moisture at the connector pins. Do not use a damaged cable.
2
Check the app for a numeric code
The app reports the specific error, which is far more useful than the colour alone.
3
Verify charger software is current
Allow any pending firmware update to finish before retesting.

These steps stay outside the enclosure. Never open high-voltage equipment, bypass safety devices or work on live wiring.

When to stop troubleshooting

Stop and contact a qualified technician if the fault returns immediately, the device smells burnt, visible wiring damage exists, the enclosure is hot to the touch, or the manufacturer specifies professional service.

Can a reset clear this fault?

Reset behaviour is not documented for this code. Use only the manufacturer-approved restart sequence described in the device manual, and treat a code that returns immediately as an unresolved fault rather than a reset problem.
