For the Samsung Dishwasher families covered by the source set, **FC3** means **drying fan / vent 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 **FC3**. Search normalization stores it as **FC3** while preserving the characters a homeowner actually sees.

Quick answer
Drying fan / vent error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so FC3 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Signs
Symptoms you may notice
One clue that supports the FC3 diagnosis is that air movement can be weak, absent, noisy, or restricted.
On affected Samsung dishwasher models, cooling or drying performance can deteriorate as airflow drops.
One clue that supports the FC3 diagnosis is that a fan may scrape, stop, or run abnormally if ice, debris, lint, or a mechanical issue is present.
One clue that supports the FC3 diagnosis is that fC3 appears during the dishwasher function associated with drying fan / vent error.
On affected Samsung dishwasher models, the cycle may stop, drain, fail to fill/heat, or repeat a stage.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
To rule out an accessible cause, clear user-accessible vents, filters, lint screens, or exterior airflow paths.
With FC3 recorded, listen for abnormal fan noise without removing live panels.
To rule out an accessible cause, verify for visible frost, lint, debris, or a crushed external duct where relevant.
To rule out an accessible cause, do not force frozen panels or reach into moving fan assemblies.
With FC3 recorded, record the code before resetting.
Before opening any service area, check water supply, drain path/filter, door, detergent/suds, and visible leaks only when relevant.
Important safety warning. When working around a dishwasher that shows FC3, keep the checks external and non-invasive. Stop use for active leakage near electrical parts, burning smell, or repeated breaker trips. Do not defeat leak or door-safety switches.

When to request repair service
If airflow paths are clear but the fan-related code returns, the motor, feedback sensor, wiring, ice/defrost condition, or control may need testing. A repeatable FC3 event is more useful diagnostically than repeated resets, because it shows when the drying fan / vent error check is failing.

Resetting can clear a temporary state, not a persistent issue. If **FC3** comes back, preserve the code and move to the safe checks or model-specific service path.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **FC3** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **FC3** 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 FC3** separate from same-looking codes used by other Samsung appliance families.
