Samsung Washer code **4C** is associated with **water supply / fill error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **4C**. Search normalization stores it as **4C** while preserving the characters a homeowner actually sees.

Water supply / fill error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so 4C may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. If resolving 4C would require energized internal access, that is the point to hand the diagnosis to a qualified technician.
For 4C, the service threshold is straightforward: If supply flow is proven good and the display returns, inlet valves, flow/level sensing, wiring, or control electronics may require diagnosis. Bring the exact model number and a photo of the display so the diagnosis stays tied to the documented Samsung code.

Water supply / fill error.
A single documented power reset can help after an external condition or power event is corrected. If **4C** returns at the same stage, repeated resets only erase useful evidence and do not repair the cause.
That depends on the accompanying symptom. A code with no safety hazard may allow a short diagnostic check, but **4C** should not be ignored if performance is deteriorating or the display keeps returning.
Not automatically. Samsung error codes are diagnostic indicators, not part numbers. Confirm the circuit around **4C** before replacing anything.
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 4C** separate from same-looking codes used by other Samsung appliance families.
