Samsung Washer Error Codes: Full List & Meanings
Updated · from manufacturer service documentation
Samsung washers use two-character codes to flag what's wrong — most trace back to water supply, drainage, or an unbalanced load, and several are DIY-fixable in under 15 minutes. Below is every code we've confirmed against Samsung's service documentation so far, with full step-by-step fixes for the ones already published; the rest are on the way.

Frequently Asked Questions
How do I reset a Samsung washer after an error code?
For most codes, powering the washer off, clearing the cause (water supply, drain path, or laundry balance), and restarting the cycle clears the display. See the code's own page for specifics.
Why does my display show "SC" instead of "5C"?
Samsung's own support documentation groups 5C and SC as the same drain-error code — the digit "5" and letter "S" render almost identically on the display. See the SC page for details.
Is every Samsung washer code a real fault?
No — some, like SUD/SUdS, are protective notifications rather than faults. Check the specific code's page before assuming a repair is needed.
