Risk level

Low

Usually safe to check without specialist tools.

Urgency

Medium

Quick answer

On a Rowenta X-plorer, Error 4 means the rolling brush cannot turn, usually because hair or threads are wrapped around it. Switch the robot off, take the brush out and clean it along with its connections, its cover and the suction inlet, then start again.

Safety first

Stop and check this first

  • Turn the robot off and take it off the dock before handling the rolling brush, so it cannot start while your fingers are near it.
  • Do not open the robot body to hunt for the jam; the cleaning in the manual covers only the brush, its cover and the suction inlet.
  • If the robot overheats, Rowenta says to stop it and let it cool for at least one hour; if that keeps happening, contact the approved service centre.

Safe checks you can perform

  • Switch off and remove the rolling brush
  • Clean the brush connections, cover and suction inlet
  • Refit the brush and close the cover
  • Restart and watch for Error W4

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Rolling brush inspection at a Rowenta approved service centre

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. Rolling brush inspection at a Rowenta approved service centre

    What they doIf Error 4 or Error W4 keeps returning after cleaning the brush, its connections, the cover and the suction inlet, the approved service centre inspects the brush assembly.

    They must show youthe condition of the brush, its end supports and the cover.

    In writingwhich part was replaced or adjusted and whether warranty covers it.

  2. Replacement of a worn rolling brush

    What they doIf the brush is bent, has broken bristles or damaged ends, the approved service centre or a Rowenta spare parts dealer can supply an original one.

    They must show youthe wear on the removed brush.

    In writingthe spare part reference and its price.

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. Switch off and remove the rolling brush

    No special tools

    Who:
    you, no tools needed.
    How:
    turn the power switch off and lift the robot off the charging dock before turning it over. Take out the rolling brush and pull away any hair, thread or debris caught in the bristles and at both ends.
    Result that matters:
    a free brush that turns by hand without resistance.
    If you find tangled debris:
    that is the most common trigger.
    If nothing was tangled:
    move on to the connections, cover and suction inlet.
    Evidence to keep:
    photo of the brush before and after cleaning.

  2. Clean the brush connections, cover and suction inlet

    No special tools

    Who:
    you, with a dry cloth.
    How:
    with the brush out, wipe the points where each end locks in, the brush cover and the suction opening, as Rowenta asks for Error 4. Empty the dust box and clean the filters as well if suction was whistling.
    Result that matters:
    no dirt left that could slow the brush or block suction.
    If there is a plug of debris at the inlet:
    remove it before refitting.
    If everything looks clean:
    check how the brush is refitted.
    Evidence to keep:
    note of what was blocking the suction inlet.

  3. Refit the brush and close the cover

    No special tools

    Who:
    you, no tools needed.
    How:
    put the rolling brush back in its housing and close the cover until it clicks firmly in place. When the brush does not rotate, Rowenta says to confirm that both brush and cover are installed correctly.
    Result that matters:
    the brush spins at start up and the alert does not return.
    If the robot cleans normally:
    the alert is resolved.
    If Error 4 comes back straight away:
    restart the robot as described below.
    Evidence to keep:
    short video of the first start after refitting.

  4. Restart and watch for Error W4

    No special tools

    Who:
    you, with the robot and the app.
    How:
    shut the robot down, wait 3 seconds and start it again, as the troubleshooting table suggests. If the app switches to Error W4 (rolling brush abnormal), Rowenta asks you to repeat the cleaning and contact its Service Department if it persists.
    Result that matters:
    telling a cleared jam apart from an alert that keeps coming back.
    If it does not return:
    nothing more is needed.
    If W4 or Error 4 returns after a full clean:
    book a Rowenta approved repair.
    Evidence to keep:
    screenshot of the app showing the code and date.

What it means

The Rowenta X-plorer Serie 75 manual says that when the robot fails, its red light blinks and the app shows the error code. Error 4 is a stuck rolling brush: Rowenta blames foreign matter tangled around it and asks you to remove the brush and clean its connections, its cover and the suction inlet too. The troubleshooting table adds that a brush that does not rotate may simply be fitted wrongly. The alert on its own does not show that the brush motor is faulty, and numbering may differ between models.

Symptoms and causes

Probable causes · in order

  • Hair, thread or debris wrapped around the brushCommon

    Rowenta attributes Error 4 to foreign matter tangled in the rolling brush, which stops it from spinning freely.

    Evidence: Rowenta X-plorer Serie 75 instrucciones de uso

  • Brush or brush cover not seatedPossible

    For a rolling brush that does not rotate, the troubleshooting table asks you to check that the brush and its cover are installed correctly.

    Evidence: Rowenta X-plorer Serie 75 instrucciones de uso

  • Blocked suction inletPossible

    The manual includes the suction inlet in the Error 4 cleaning, and links a clogged intake head to whistling during suction.
