For the Samsung Dishwasher families covered by the source set, **6C** means **stuck-key / control-panel error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **6C**. Search normalization stores it as **6C** while preserving the characters a homeowner actually sees.

Quick answer
Stuck-key / control-panel error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 6C 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
For the Samsung Dishwasher families covered by the source set, **6C** means **stuck-key / control-panel error**. The first useful step is to preserve the exact characters and model number before power cycling the appliance. The useful diagnostic value of the code is the subsystem it identifies. A good repair process confirms the symptom, checks the accessible external conditions, and then follows the model-specific circuit only if the display returns. The recorded display form is **6C**. Search normalization stores it as **6C** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
When the 6C condition is present, the appliance may stop or limit the affected function when the code is detected.
While 6C is active, the same code can return at a repeatable stage of operation.
The 6C display becomes more meaningful if other symptoms depend on the model and the subsystem named by Samsung.
One clue that supports the 6C diagnosis is that 6C appears during the dishwasher function associated with stuck-key / control-panel error.
A symptom that fits 6C is that the cycle can stop, drain, fail to fill/heat, or repeat a stage.
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
A safe owner-level check is to record the exact code, model number, and operating stage before resetting power.
As an external check for 6C, complete only the owner-accessible checks described in the model manual.
The next non-invasive check is to do not replace parts solely from a display code when wiring, conditions, or control feedback can create the same result.
To rule out an accessible cause, record the code before resetting.
Before requesting service for 6C, check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
To rule out an accessible cause, if the code returns after the supported owner checks, request model-specific diagnosis.
Important safety warning. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches. If resolving 6C would require energized internal access, that is the point to hand the diagnosis to a qualified technician.

When to request repair service
If the code returns after the documented basic checks, request model-specific diagnosis of the affected subsystem. A repeatable 6C event is more useful diagnostically than repeated resets, because it shows when the stuck-key / control-panel error check is failing.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
One controlled restart is reasonable after correcting an obvious external issue. A recurring **6C** display should be treated as diagnostic evidence, not as a reason to keep rebooting the appliance.
Short owner-accessible checks may be reasonable when the appliance is safe. Persistent **6C**, worsening performance, or any electrical/water/heat hazard is a reason to stop use.
The code alone is not enough to justify a part. **6C** should narrow testing to the affected function; the final cause still has to be verified on the exact model.
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 **Dishwasher 6C** separate from same-looking codes used by other Samsung appliance families.
