Samsung Washing Machine Error Codes
25 error codes with causes and fixes
- 4ENo 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.
- 4CSlow or interrupted water fill4C flags insufficient fill rate rather than a total no-fill. Samsung monitors flow after the valves open; a trickle, pressure drop, or one dead solenoid side triggers 4C even when some water is visible through the door glass.
- UBLoad too unbalanced for spinUB is an Unbalanced error at high-speed spin. Samsung's MEMS vibration sensor reads drum movement; when weight sits on one side the inverter ramps down and displays UB rather than walk the cabinet across the floor.
- DCEarly 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.
- LELeak 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.
- OEOverflow—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.
- HEWater 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.
- 3EDirect-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.
- AECommunication 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.
- BEStuck 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.
- CECooling 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.
- DEDoor 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.
- EEControl 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.
- FELine 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.
- TEWash 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.
- NDNo drain—water still in tubND is Samsung's No Drain fault—the drain pump ran but the water level sensor still detected water after the drain phase. The washer stops before spin to avoid sloshing a full tub.
- 5EDrain error—same family as ND on some models5E indicates a drain problem on Samsung washers—many models alternate between 5E and ND for the same slow-drain detection depending on firmware year.
- 9C8Power frequency or voltage irregularity9C8 reports the control detected abnormal line frequency or voltage—common after brownouts, generator power, or loose neutral connections on the laundry circuit.
- 8CMem sensor or load balance fault8C relates to Samsung's mems sensor or vibration detection—the board measured excessive drum movement or invalid sensor feedback before high-speed spin.
- 3CMotor or inverter drive fault3C indicates the motor inverter could not drive the drum at commanded speed—overload, jam, or failed motor/inverter components.
- SUDExcessive suds in the tubSUD means the washer detected too much foam—the foam blocks accurate water level reading and Samsung extends rinse time or pauses the cycle until suds drop.
- SCControl panel or communication faultSC indicates a System Communication error between the main PCB and sub-boards or the display—cycles may freeze or cancel mid-program.
- URUnbalanced load—spin abortedUR stops spin when the drum is unbalanced—Samsung measures weight distribution and aborts high RPM rather than walk the machine across the floor.
- NFNo fill—water not detectedNF means No Fill—the valves opened but the water level never rose within the fill timeout on Samsung top and front loaders.
- SEMotor sensor or hall feedback faultSE indicates a Sensor Error on the motor feedback circuit—the hall or tach signal did not match commanded drum speed.
