Samsung washers show a short code whenever something stops the cycle. Most point to water supply, draining, balance or the door, and those four are often fixable without a service call. Codes may display slightly differently by model and age (for example 4C or 4E), but they mean the same thing.

What do the common Samsung washer codes mean?
| Code | Meaning | Common causes | Try first |
|---|---|---|---|
| 4C / 4E | Water supply problem | Valves off, kinked hose, clogged inlet screens | Open both valves, check hoses |
| 5C / 5E / SE | Drain problem | Clogged pump filter, kinked drain hose | Clean pump filter |
| UB / UE / Ub | Unbalanced load | Bunched load, unlevel washer | Redistribute, level feet |
| dC / dE / dL / LO | Door or lid lock | Door not closed, latch debris, lock failure | Close firmly, clean latch |
| 3C / 3E | Motor problem | Overload, wiring, motor or hall sensor | Smaller load, reset |
| LC / LE | Water level or leak detected | Leak in base, drain issue, overfill | Check for water under the unit |
| Sud / Sd | Too many suds | Too much or non-HE detergent | Cut detergent, rinse cycle |
How do I reset a Samsung washer?
Unplug it (or flip its breaker) for about 10 minutes, plug it back in and run a rinse-and-spin cycle. A reset clears temporary faults. If the same code returns, there's a real cause to fix.
Which codes need a technician?
3C/3E codes that keep returning on normal loads usually mean a motor, hall sensor or wiring issue. LC/LE codes with water in the base need someone to find the leak. dC codes that return even with a clean latch often mean the door lock has failed.
Elliott's take
On a Samsung washer, write the code down before you reset it. Once it's cleared, it's gone, and "it showed some letters" doesn't help anyone diagnose it. A photo of the display saves real time.
