Quick answer

On a Schneider Electric EVlink Home or EVlink Home Smart charger, a constant red LED means a fault has been detected. First verify that the stop button is not locked by rotating it 90 degrees clockwise; if the red light stays on, run the power-off reset sequence and call a qualified electrician.

Safety first

Stop and check this first

  • Checking the PE terminal wiring requires opening the enclosure and testing the electrical supply: Schneider Electric states that servicing and maintenance must be performed only by qualified personnel.

Safe checks you can perform

  • Rotate the stop button 90 degrees clockwise
  • Switch off power, unplug the EV and wait for the green LED
  • Check the device history in the Wiser app on Home Smart units

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Protective Earth (PE) terminal and earthing inspection
  • Do not attempt this professional task: Supply verification and escalation to Schneider Electric Customer Care

What a technician must be able to justify

Technician visit

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. Protective Earth (PE) terminal and earthing inspection

    What they doA qualified electrician isolates the supply, opens the charger and checks that the protective earth conductor is securely wired to the charger's PE terminal and the distribution board.

    They must show youthe physical termination at the charger PE terminal and the earth continuity and loop impedance readings.

    In writingthe condition of the PE terminal wiring, the earth resistance or loop impedance measured and any re-termination done.

  2. Supply verification and escalation to Schneider Electric Customer Care

    What they doIf the PE connection and supply voltage are sound but the constant red LED persists with no vehicle connected, the electrician documents the readings and contacts Schneider Electric's Customer Care Centre.

    They must show youthe measured supply voltage and the LED status when energised with the vehicle disconnected.

    In writingthe supply readings, the EVlink commercial reference and serial number, and the Customer Care Centre case reference.

Before accepting a part or repair

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

Follow these steps

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

  1. Rotate the stop button 90 degrees clockwise

    No special tools

    Who:
    you, at the outside of the EVlink Home charger.
    How:
    check the red stop button on the charger housing and rotate it 90 degrees clockwise to make sure it has not been pushed in and latched.
    Result that matters:
    ruling out a locked stop button, which is the first cause in Schneider Electric's troubleshooting table.
    If the button releases and the LED returns to green standby:
    the stop button was holding the unit in fault.
    If the button was already released or the LED remains constant red:
    continue to the power-cycle sequence.
    Evidence to keep:
    a photo of the stop button position and the LED colour after rotating it.

  2. Switch off power, unplug the EV and wait for the green LED

    No special tools

    Who:
    you, using the circuit breaker and the vehicle connector.
    How:
    switch off the power supply of the charger, unplug the connector from the EV, switch the power supply back on and wait for the LED to glow green before reconnecting the connector to the EV.
    Result that matters:
    carrying out the exact reset sequence Schneider Electric specifies before calling for electrical service.
    If the LED glows green and then pulses cyan blue when charging starts:
    keep an eye on whether the fault recurs.
    If the LED stays red before or right after reconnecting the car:
    stop retrying and call a qualified electrician.
    Evidence to keep:
    a note of the LED colour when powering back up with the car unplugged and after reconnecting.

  3. Check the device history in the Wiser app on Home Smart units

    No special tools

    Who:
    you, from your smartphone without opening the charger.
    How:
    if you have an EVlink Home Smart paired with the Wiser app, open the device history screen and note the date and time the session stopped.
    Result that matters:
    saving session details for your electrician or Schneider Electric's Customer Care Centre.
    If the failed session is logged in the app:
    take a screenshot to hand over to the technician.
    If you have a non-smart EVlink Home or no cloud link:
    write down the time of the fault and the vehicle model.
    Evidence to keep:
    a screenshot from the Wiser app or a written note of the time and vehicle.

What it means

In the EVlink Home Smart Device User Guide (DUG_EVlink_WSE-02, LED indications and Troubleshooting sections), a constant red LED means 'Fault detected, please refer to troubleshooting'. Schneider Electric's troubleshooting table gives three steps in order: verify that the stop button is not locked by rotating it 90 degrees clockwise, switch off the power supply, unplug the EV and wait for the green ready LED after switching power back on before reconnecting, and check that the power supply is securely wired to the charger's PE (Protective Earth) terminal. A red LED alone never proves a component has failed.

Warnings and stop conditions

Symptoms and causes

Probable causes · in order

  • Stop button pressed in and lockedCommon

    Schneider Electric lists checking whether the stop button is locked, and rotating it 90 degrees clockwise to release it, as the very first step when the charger LED is illuminated red.

    Evidence: EVlink Home Smart Device User Guide: Troubleshooting (DUG_EVlink_WSE-02)

  • Latched fault state during the vehicle charging sessionPossible

    The troubleshooting table provides a reset sequence (power off, unplug EV, power on and wait for the green ready LED before reconnecting) that clears session-related faults.

    Evidence: EVlink Home Smart Device User Guide: Troubleshooting (DUG_EVlink_WSE-02)

  • Loose or missing connection at the Protective Earth (PE) terminalPossible

    If unlocking the stop button and cycling power with the vehicle unplugged do not clear the red LED, the guide directs checking that the supply is securely wired to the charger's PE terminal.
