Risk level

Low

Usually safe to check without specialist tools.

Urgency

Low

Quick answer

On a Samsung washer, Cb or C6 shows calibration mode, which recalibrates load weight detection. The drum rotates back and forth for 1 to 3 minutes and stops by itself; the washer must be empty.

Safety first

Stop and check this first

  • Do not reach into the drum while it rotates during calibration: wait until it has stopped completely before opening.

Safe checks you can perform

  • Empty drum
  • How long calibration takes
  • If it never ends or returns every wash

Leave these tasks to a qualified professional

  • Do not attempt this professional task: Load detection check
  • Do not attempt this professional task: Full calibration after the check

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. Load detection check

    What they doIf calibration does not finish with an empty drum, the technician checks the weight detection system and its connections using Samsung's service documentation.

    They must show youthe calibration reproduced and the part or connection stopping it from finishing.

    In writingthe cause, the part replaced with its part number and the reason.

  2. Full calibration after the check

    What they doTo finish, the technician starts a calibration with the drum empty and checks it ends by itself within Samsung's stated time.

    They must show youthe calibration ending by itself with an empty drum.

    In writingthe test, how long it took and the date.

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. Empty drum

    No special tools

    Who:
    you, no tools.
    How:
    with the washer stopped, open the door and take out all laundry before letting it calibrate.
    Result that matters:
    the conditions Samsung requires for a correct calibration.
    If it was empty:
    let calibration continue.
    If there was laundry:
    take it out and start calibration again with the drum empty.
    Evidence to keep:
    note of whether there was laundry inside.

  2. How long calibration takes

    No special tools

    Who:
    you, observing.
    How:
    check the time when it starts and wait without touching anything while the drum rotates back and forth.
    Result that matters:
    whether it ends by itself within the 1 to 3 minutes Samsung gives.
    If it ends in that time:
    calibration is done; use the washer normally.
    If it runs well beyond 3 minutes or stops with another code:
    note it and go to the next step.
    Evidence to keep:
    start and finish times.

  3. If it never ends or returns every wash

    No special tools

    Who:
    you.
    How:
    note how often Cb appears without you starting it and any other code shown, and contact Samsung support with the model.
    Result that matters:
    a clear request if the load detection will not calibrate.
    If it appeared once and finished:
    no request needed.
    If it keeps returning or does not finish with an empty drum:
    ask for a technician.
    Evidence to keep:
    log of dates and codes.

What it means

Samsung US explains that Cb and C6 show calibration mode: the washer recalibrates its weight detection, which it uses to adjust the amount of water for each cycle. During calibration the drum rotates back and forth for 1 to 3 minutes and ends by itself. Samsung warns it will not calibrate correctly unless the washer is empty. So Cb is not a fault in itself; it only needs attention if calibration does not finish or shows up on every use, and then a technician should check the load detection.

Warnings and stop conditions

  • Loweditorial warning

    Do not reach into the drum while it rotates during calibration: wait until it has stopped completely before opening.

Symptoms and causes

Probable causes · in order

  • Calibration in progressCommon

    The usual case: the washer is in the mode Samsung describes and finishes alone within 1 to 3 minutes. Not a fault.

  • Calibrating with laundry insidePossible

    Samsung warns it will not calibrate correctly with a load. Ruled out by removing the laundry and repeating calibration.

  • Weight detection that will not calibrateLess common

    If calibration with an empty drum never ends or keeps repeating, the load detection needs a technician.
