Risk level

High

Professional inspection is recommended.

Urgency

Immediate

Quick answer

SOLID RED means the Wall Connector has an internal fault and charging is disabled in the cited charger family. The deciding observation is whether solid red remains after the single five-second breaker-off cycle Tesla specifies. Do not infer a failed part from the code alone.

Safety first

Stop and check this first

  • Smoke, burning smell, sparks, water, visible damage, abnormal heat or repeated protective-device trips means stay clear and leave charging disabled. Never open the charger, panel or connector and never probe voltage yourself.

Safe checks you can perform

  • Capture the exact charger, vehicle and pattern
  • Run the one deciding check
  • Use recurrence as the stop point

Leave these tasks to a qualified professional

What a technician must be able to justify

A technician is coming

These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.

These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.

  1. Measured handoff for SOLID RED

    What they doUse part/serial number and diagnostic logs to identify the internal failure path before approving a Wall Connector replacement.

Before accepting a part or repair

Nothing has been shown yet. Do not accept a part swap based on the code alone.

Checks and evidence, step by step

Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

  1. 1

    Capture the exact charger, vehicle and pattern

    No special tools

    Procedure

    Photograph SOLID RED and record the Tesla model, part/serial number, vehicle model, cable used, charge stage and approximate time. Do not clear the event before those facts are saved.

    Smoke, burning smell, sparks, water, visible damage, abnormal heat or repeated protective-device trips means stay clear and leave charging disabled. Never open the charger, panel or connector and never probe voltage yourself.

  2. 2

    Run the one deciding check

    No special tools

    Procedure

    Disconnect the vehicle. Turn the labelled breaker off, wait five seconds and turn it on once. Do not open the Wall Connector. Record whether solid red remains after the single five-second breaker-off cycle Tesla specifies. Change one condition only.

    Smoke, burning smell, sparks, water, visible damage, abnormal heat or repeated protective-device trips means stay clear and leave charging disabled. Never open the charger, panel or connector and never probe voltage yourself.

  3. 3

    Use recurrence as the stop point

    No special tools

    Procedure

    If green returns, the controller restarted; keep the event because the cycle does not identify the original internal condition. If solid red remains, Tesla’s user branch ends: record part and serial numbers and contact Tesla without further cycles.

    Smoke, burning smell, sparks, water, visible damage, abnormal heat or repeated protective-device trips means stay clear and leave charging disabled. Never open the charger, panel or connector and never probe voltage yourself.

What it means

Tesla’s official documentation defines SOLID RED as the Wall Connector has an internal fault and charging is disabled. That is the protection or controller state, not a universal component diagnosis. If green returns, the controller restarted; keep the event because the cycle does not identify the original internal condition. If solid red remains, Tesla’s user branch ends: record part and serial numbers and contact Tesla without further cycles.

Warnings and stop conditions

  • Highsource verified

    Smoke, burning smell, sparks, water, visible damage, abnormal heat or repeated protective-device trips means stay clear and leave charging disabled. Never open the charger, panel or connector and never probe voltage yourself.

Symptoms and causes

Probable causes · in order

  • What the manufacturer code establishesConfirmed

    Tesla documents SOLID RED as a state in which the Wall Connector has an internal fault and charging is disabled. Keep this meaning scoped to the cited charger family and exact light/code pattern.
