If a Samsung washing machine shows **Cb**, the verified Samsung meaning in this research set is **calibration mode / calibration code**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **Cb**. Search normalization stores it as **CB** while preserving the characters a homeowner actually sees.

Quick answer
Calibration mode / calibration code.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so CB may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
If a Samsung washing machine shows **Cb**, the verified Samsung meaning in this research set is **calibration mode / calibration code**. Use the code to narrow the diagnosis, then confirm the exact model because code scope can change by product generation or region. A display code is evidence from the control system, not a component test result. That distinction matters because a connector, supply condition, obstruction, or feedback signal can mimic a failed component. The recorded display form is **Cb**. Search normalization stores it as **CB** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
On affected Samsung washing machine models, the display appears while the appliance is otherwise able to respond as expected.
When the Cb condition is present, the message can be tied to a mode, test, reminder, setup state, or protective condition rather than a failed part.
On affected Samsung washing machine models, normal operation may resume after the documented mode or condition is cleared.
Cb can be accompanied by this pattern: cb appears on the display while the appliance reports: Calibration mode / calibration code.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
With Cb recorded, confirm the exact display characters and appliance model before treating the message as an issue.
A safe owner-level check is to check the user-facing setting, mode, door, filter, container, or setup condition named by Samsung for this display.
With Cb recorded, use the model-specific manual to clear the status; avoid repeated resets if the message returns unexpectedly.
For Cb, start by doing this: record the code and the cycle stage where it appears.
The next non-invasive check is to check owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
For Cb, start by doing this: power-cycle once only where Samsung's guidance recommends it; if the same code returns, move to model-specific diagnosis.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. For Cb, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

When to request repair service
If the owner-accessible checks do not clear Cb, Service is not automatically required. Request diagnosis only if the status cannot be cleared as designed or normal operation does not resume. The repair should confirm the monitored function and its feedback before any board or component is condemned.

You can try the one reset Samsung documents for the model, but **Cb** returning afterward means the condition still exists. Note the operating stage instead of cycling power repeatedly.
The display can be normal in the documented context. If **Cb** appears unexpectedly, cannot be cleared, or prevents normal operation, then the issue deserves diagnosis.
Treat **Cb** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Washer Cb** separate from same-looking codes used by other Samsung appliance families.
