The complete reference for Samsung error codes across washers, dryers, dishwashers, refrigerators, and ovens. Pick your appliance below for the full code breakdown organized by problem category.
Samsung uses a letter-and-digit coding system that varies by appliance type and generation. Older models display short alphanumeric codes like 4E, OE, or UE — two characters that combine a category number with a letter for the failure type. Newer Samsung models often use 4C, 5C, 9E conventions (the "C" in newer codes is sometimes a successor to "E" — same fault category, different generation).
Ovens and refrigerators use slightly different formats: ovens prefix with E followed by 2–3 digits (e.g. E27) or C- followed by alphanumerics (C-d1, C-F0). Refrigerators display 2-character codes ending in E (5E, 22E, 33E) tied to specific sensors and components.
The biggest practical difference versus other brands: Samsung's SmartThings app pulls error codes directly from connected appliances, often with a one-tap diagnostic. If your appliance is paired, check the app before troubleshooting manually — it often surfaces the code and a recommended first step in plain language.
Each link below leads to the full appliance-specific page where codes are organized into problem categories (water supply, drainage, motor, door, heating, sensors) — not a flat alphabetical list — so you can find your fault even if you only know the symptom, not the code.
Samsung washer codes group into four problem categories: Water Supply Drainage Balance & Door Temperature & Heating. The full appliance page walks through each category with diagnostic steps.
Dryer codes split between Heating (tE, HE, t5) and Door & Switch (dC, dF) categories. Heating faults are the more serious group — they often involve a tripped thermal fuse or a failing heating element.
Samsung dishwasher codes are heavily concentrated in Water Handling faults — supply, drainage, leak detection, and overflow. The LC and OC codes signal active leak or flood conditions and require immediate action.
Refrigerator codes split into Sensors & Defrost (5E, 88) and Ice Maker & Compressor (22E, 33E, 39E). The Family Hub display sometimes shows these alongside plain-language alerts via the touchscreen.
Samsung oven codes use a different format — E-prefixed numerics for sensors and C- prefixes for control or door faults. Most oven errors here fall into Sensors and Door & Control categories.
