Samsung Washing Machine Error Cb: Calibration Mode Active

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The washer is running a calibration cycle to recalibrate its load weight detection sensors. This is a maintenance mode, not a fault.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the Samsung washing machine.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

Calibration mode was manually activated via the control panel

Also displayed as Cb, C6 on some models.

Estimated time for safe first checks: 3–5 min (mode runs automatically).

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard — Cb is a mode indicator, not a fault.
  2. Ensure the washer drum is completely empty — remove all laundry.
  3. Allow the calibration cycle to complete — it typically takes 3–5 minutes.
  4. The washer will return to standby mode automatically when calibration is complete.
  5. If Cb appears when you did not intend to start calibration, press Power Off to cancel and restart.

If the warning comes back after restart

  • If the warning returns immediately after a clean restart, the sensor or wiring path becomes more likely than a one-time glitch.
  • Cb appears automatically on every power-on and cannot be cancelled — firmware or board fault suspected
