How Samsung Error Codes Work

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.

Most Common Faults

Water inlet, drainage, unbalanced load

Samsung Washer Error Codes

8 codes · Covers top-load, front-load, and FlexWash models

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.

Water issue — kinked hose, closed valve, or low pressure.

Drainage error — drain hose clogged or filter blocked

Water overflow — water level sensor or pressure switch fault

Unbalanced load — redistribute clothes or check shock absorbers

Water issue — kinked hose, closed valve, or low pressure.

Drainage error — drain hose clogged or filter blocked

Water overflow — water level sensor or pressure switch fault

Unbalanced load — redistribute clothes or check shock absorbers

Door not closed properly during cycle

Temperature sensor (thermistor) failure

Door not closed properly during cycle

Temperature sensor (thermistor) failure

Organized by problem category, with diagnostic steps

Samsung Dryer Error Codes

5 codes · Covers electric, gas, and heat-pump models

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.

Temperature sensor (thermistor) out of range

Heating error — element, thermal fuse, or vent restriction

Door not closed during cycle start

Door lock assembly failure

Temperature sensor (thermistor) out of range

Heating error — element, thermal fuse, or vent restriction

Door not closed during cycle start

Door lock assembly failure

Heat coil temperature sensor abnormal reading

Heat coil temperature sensor abnormal reading

Samsung Dishwasher Error Codes

5 codes · Covers DW-series and StormWash models

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.

Water supply error — inlet valve or hose problem

5C
DIY

Drainage error — filter, pump, or hose blockage

Low water level — insufficient fill during cycle

Water leak detected — anti-flood sensor triggered

Water supply error — inlet valve or hose problem

Drainage error — filter, pump, or hose blockage

Low water level — insufficient fill during cycle

Water leak detected — anti-flood sensor triggered

Water overflow — pressure switch or inlet valve stuck open

Critical

Water overflow — pressure switch or inlet valve stuck open

Samsung Refrigerator Error Codes

5 codes · Covers French door, side-by-side, and Family Hub models

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.

Defrost sensor (thermistor) fault

Compressor relay error — cooling at risk

Ice maker function fault

39E

Ice maker water line or supply issue

Defrost sensor (thermistor) fault

Compressor relay error — cooling at risk

Ice maker function fault

Ice maker water line or supply issue

Display test pattern — usually after a power event

Display test pattern — usually after a power event

Samsung Oven & Range Error Codes

3 codes · Covers freestanding, slide-in, and dual-fuel models

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.

Oven temperature sensor open or shorted

Door latch motor or switch failure during self-clean

Control communication error between main board and display

Oven temperature sensor open or shorted

Door latch motor or switch failure during self-clean

How to tell which Samsung error codes you can clear yourself — and which need a technician.

DIY Friendly

You can probably fix it yourself if…

The code falls in this list and the appliance is otherwise functional:

  • 4E / 4C — check water supply valves and inlet hose for kinks

  • 5E / 5C — clean the drain filter and inspect the drain hose

  • UE — redistribute the laundry load and restart

  • dC — fully close the door, check for obstructions in the seal

  • 9E (dishwasher) — verify water supply pressure

  • 39E — refill ice maker water line or check shutoff valve

  • 88 — usually clears after a power event reset (unplug 1 min)

You should book a technician if…

The code indicates a hardware fault, or you see any of these signs:

  • HE (dryer), LC / OC (dishwasher) — Critical: stop using immediately

  • OE, tE, dF, t5, E27 — sensor or motor faults require parts diagnosis

  • 22E, 5E (refrigerator), 33E — cooling system or compressor risk

  • C-d1, C-F0 (oven) — control board or door latch replacement

  • Code returns after a full reset and basic checks

  • SmartThings shows the code persistently across cycles
