The **4E** display on a Samsung washing machine points to **water supply / fill error**. Treat it as a diagnostic direction rather than a parts order: operating conditions, wiring, sensors, actuators, and control electronics can overlap. Samsung uses overlapping code conventions across model years and regions. This page keeps the appliance context attached to the code so a same-looking string from another product family is not misapplied. The recorded display form is **4E**. Search normalization stores it as **4E** while preserving the characters a homeowner actually sees.

Model compatibility: Samsung can reuse or reformat codes across series and model years, so 4E 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. For 4E, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.
For 4E, 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 **4E** 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 **4E** should not be ignored if performance is deteriorating or the display keeps returning.
The code alone is not enough to justify a part. **4E** 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 **Washer 4E** separate from same-looking codes used by other Samsung appliance families.
