Samsung Washing Machine Error Codes
Samsung washers show 4C, 5C, nd, UE, and dC codes on the display or SmartThings. AddWash and EcoBubble models share most fault logic.
General troubleshooting
Try these checks before opening a specific error code page—they resolve many Samsung washing machine faults without parts.
- 1Check both supply hoses and clean inlet valve screens on WF45T6000AW and similar
- 2Clean the drain pump filter at the front lower access panel
- 3Run Spin Only with an empty drum after redistributing a heavy load
- 4Close the AddWash door firmly if your model has the secondary door
- 5Update firmware through SmartThings if Samsung publishes a control board fix
Common symptoms
Owners often search for a code after noticing one of these issues on their Samsung washing machine:
- 4C or 4E fill errors when water enters slowly
- 5C, SC, or nd drain faults with water in the tub
- UE unbalanced load before spin on WF45 and WF50 series
- dC or dc door faults when the latch doesn't confirm
- 3C or motor faults when the drum won't rotate
All Samsung washing machine error codes
| Code | What it means | Guide |
|---|---|---|
| 3C | Motor position sensor not calibrated3C indicates the motor position sensor did not report expected rotor position at startup or during load sensing. Samsung's inverter needs hall sensor feedback to commutate the brushless motor—3C stops the cycle before agitation. | View fix → |
| 3E | Direct-drive motor or hall sensor fault3E (also SE or EA on related displays) means the inverter did not get valid feedback from the brushless motor or hall sensor. The drum may hum briefly then stop. Check your manual—on a few Samsung models 3E indicates voltage error instead of motor fault. | View fix → |
| 4C | Water fill too slow or interrupted before the tub reaches target levelSamsung 4C is a fill-rate fault in the same diagnostic family as 4E (Not Filling). After the main control energizes the dual inlet valve solenoids, the pressure switch or flow sensor must confirm rising water within roughly 60 seconds on most WF45 and WF50 front-load platforms. 4C differs from 4E in that some water may enter the drum—a trickle, a single dead solenoid side, or a mid-fill pressure drop can trigger 4C while the door glass still shows a shallow puddle. The washer aborts before heat or agitation to protect the heating element and motor from running dry. | View fix → |
| 4E | No water entering the tub4E is Samsung's Not Filling error. The inlet valves energize but the water level sensor never sees a rise within the programmed fill window—often within two to four minutes depending on cycle. The machine aborts before agitation to avoid running dry. | View fix → |
| 5E | Drain fault—same family as ND and 5C; pump timeout with water in tubSamsung 5E is a drain error in the same family as ND and 5C on front-load washers—the control ran the drain pump for the programmed interval (often 15 minutes or more on some cycles) but the water level sensor still detected water in the tub. Display may show 5E, SE, or ND depending on firmware region. On WF45T6000AW and similar, service access is through the lower front access panel with a black emergency drain hose and twist-off filter cap—not the top-loader path. 5E is not a fill fault (see 4C) or balance fault (see UB). | View fix → |
| 8C | MEMS vibration sensor communication fault8C flags the MEMS imbalance sensor—the accelerometer on the tub frame that monitors vibration during spin. Samsung cannot safely ramp RPM without valid MEMS data, so spin aborts and 8C displays. | View fix → |
| 9C8 | AC power frequency out of tolerance9C8 reports the control detected mains frequency outside Samsung's acceptable band—often below 45 Hz or above 65 Hz on the sensing circuit. Washers on extension cords, generator backup, or damaged supply legs see 9C8 at startup. | View fix → |
| AE | Communication fault between PCBsAE (AC6, ACb variants) is a Communication Error between Samsung's main control and a sub-board—display, inverter, or Wi-Fi module. Cycles may freeze mid-step or refuse to start until the link restores. | View fix → |
| BE | Stuck button or vibration sensor faultBE has two meanings on Samsung washers: a Jammed Button detected held more than ten seconds, or on other models a MEMS vibration sensor fault (same family as 8E). Your user manual identifies which applies—button BE is far more common on front-touch panels. | View fix → |
| CE | Cooling fault on washer-dryer combo unitsCE on Samsung washer-dryer combos means the cabinet overheated and the cooling fan runs until temperature drops. On separate washers, CE groups with 4C2 when cold supply water arrives too hot because hoses are swapped red-to-blue. | View fix → |
| DC | Early imbalance before spin ramp-upDC fires during Samsung's pre-spin tumble sequence—before full RPM. The washer tries several slow rotations to even out laundry; if the drum still reads off-center, DC displays and the cycle pauses. | View fix → |
| DE | Door not locked before cycle startdE (dE1, dE2, dL variants) stops fill and spin because the door lock switch never reported locked. Samsung front-loaders require confirmed latch before the inlet valves open—Child Lock with water in the tub can also trigger dE. | View fix → |
| EE | Control board EEPROM memory faultEE is an EEPROM fault—the main control cannot read stored calibration and cycle data reliably. Samsung may flash random segments or refuse cycles until the board passes self-test. | View fix → |
| FE | Line frequency or power sensing faultFE is a Frequency Error—the control detects mains supply outside expected 60 Hz (or 50 Hz export models) or the frequency sensing circuit on the board failed. Similar root causes as 9E voltage faults. | View fix → |
| HE | Water not reaching target temperatureHE (with HC on related firmware) means the NTC thermistor or heating element circuit failed to bring wash water to the setpoint within the allowed time. Samsung pauses heat to protect the element and wiring. | View fix → |
| LE | Leak or moisture detected in baseLE (also LE1 or lE) indicates water where it should not be—typically at the base leak sensor or along the door boot channel. Samsung cuts fill and may stop the cycle to limit floor damage. This is unrelated to LG's motor LE code. | View fix → |
| ND | Water not draining from the drumND is Samsung's No Drain error—the drain pump ran but the water level sensor still read high after the allotted drain window. The washer stops before high-speed spin to avoid running with a full tub. | View fix → |
| NF | No water detected during fillnF (also shown as 4E on newer displays) means Not Filling—the inlet valves opened but the water level sensor never saw a rise within the fill window. Samsung aborts before agitation to protect the drum from dry running. | View fix → |
| OE | Overflow—tub water level too highOE (also 0E or OC on some displays) reports water above the expected level in the tub. The pressure switch or level sensor sees a high reading—often from a stuck-open inlet valve, blocked pressure dome hose, or suds fooling the sensor. | View fix → |
| SC | Communication lost between control boardsSC reports lost communication between the main PCB and subsystems—often the UI board, inverter, or Wi-Fi module. Buttons may freeze and SC flashes when the handshake fails at power-on or mid-cycle. | View fix → |
| SE | System error—motor or control faultSE is a general System Error on Samsung washers—often paired with motor faults 5E or 3C on the same cycle. The main board logged an unspecified fault in the drive or communication subsystem and halted the cycle. | View fix → |
| SUD | Excess suds slowing drain and spinSUD (also shown as 5Ud) means Samsung detected excessive suds during drain or spin. The washer extends drain time trying to break foam and may pause with SUD on the display until suds level drops. | View fix → |
| TE | Wash water temperature sensor invalidtE (tC variants) reports an invalid NTC thermistor reading—open, shorted, or changing too slowly during heat-up. Samsung disables heating until the sensor circuit reads within spec, often paired with HE on retries. | View fix → |
| UB | Unbalanced load—spin aborted because drum vibration exceeded safe limitsSamsung UB means Unbalanced—not UE, which some forums confuse with LG's imbalance code. During the spin ramp, the MEMS vibration sensor on the tub or cabinet reads excessive oscillation when laundry clumps on one side of the drum. The inverter reduces RPM and displays UB rather than allow the cabinet to walk or strike the enclosure. On WF45T6000AW and WF45R6300AW front loaders, UB is usually load distribution or leveling; repeated UB on balanced loads points to worn shock absorbers or suspension springs inside the tub assembly. | View fix → |
| UR | Unbalanced load—redistribute and retry spinUR is Samsung's Unbalanced Reload code—the drum could not redistribute laundry enough to safely reach spin speed. The washer pauses and displays UR so you can open the door and rearrange items. | View fix → |
