Samsung can reuse similar displays across product families. The exact washing machine manual is the deciding source when a code differs by market or production year.
Select the characters exactly as shown. Each guide separates safe user checks from model-specific service work.
The 1C / 1E display on many Samsung washing machines indicates that the water-level sensor signal is abnormal. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung currently groups 2E with its washer voltage-error family. The code means the washer detected an irregularity in the electrical current or supply, so the useful first checks are the power source, dedicated circuit, extension-cord use, and whether a power interruption or breaker event occurred.
The 3C / 3E display on many Samsung washing machines indicates that the motor or motor feedback is abnormal. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The 4C / 4E display on many Samsung washing machines indicates that water is not entering correctly. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung groups 4C2 with hot/cold supply errors such as 4E2, CE, 14C2, and nF1. On supported models the cold inlet is receiving water that is too hot, most commonly because the hot and cold supply hoses are connected to the wrong inlets.
Samsung uses 5C / 5E for a drainage problem on supported washing machines. The first checks are the drain hose, its installation, and the user-accessible debris or pump filter where the model provides one.
Samsung 5d is a display variant of Sd or SUd on supported washers and means excessive suds were detected. The washer normally pauses and extends rinsing so the foam can dissipate, then continues automatically.
Samsung 5d is a display variant of Sd or SUd on supported washers and means excessive suds were detected. The washer normally pauses and extends rinsing until foam falls, then continues automatically; 5E or 5C is a different drainage fault.
The 8C / 8E display on many Samsung washing machines indicates that the vibration sensor signal is abnormal. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung groups 9C1 with washer voltage errors. On supported Active DualWash models Samsung specifically describes 9C1 as an over-voltage/electronic-control condition, so the first checks are the incoming power supply and whether the washer is on a proper dedicated circuit.
Samsung identifies 9C2 as a washer voltage error and, on supported Active DualWash models, specifically as low voltage. The useful first checks are the plug, wall supply, and whether the washer is being fed through an unsuitable extension or overloaded circuit.
The A0 display on many Samsung washing machines indicates that the washer is in a test-related mode. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The AC / AE display on many Samsung washing machines indicates that the control boards are not communicating. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The AC6 display on many Samsung washing machines indicates that communication with the inverter is interrupted. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The bC / bE display on many Samsung washing machines indicates that a control-panel button appears stuck. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The dC1 display on many Samsung washing machines indicates that the main door lock signal is abnormal. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung specifically defines dC3 (and ddC) as an Add Door error on washer models equipped with that small secondary door. The control cannot confirm that the Add Door is closed and locked, so troubleshooting should stay focused on the Add Door opening, latch, trapped items, and visible damage rather than the main washer door.
The ddC display on many Samsung washing machines indicates that the AddWash door was opened without pausing. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung uses dE / dC on supported washing machines when the door or lid is open, obstructed, overloaded, or cannot be confirmed as securely closed.
The E2 display on many Samsung washing machines indicates that a control-panel key is stuck. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung includes FL in its normal washer door-error group, meaning the main door is not detected as closed and locked. This differs from dC3/ddC, which Samsung reserves for the Add Door on models that have the smaller secondary opening.
The HC / HE display on many Samsung washing machines indicates that the water-heating system is abnormal. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The Hot display on many Samsung washing machines indicates that the drum is still too hot to unlock safely. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung groups Hr with washing-machine heater errors, and older model-specific Samsung support describes Hr as a heater-relay operation fault. This is a wash-heating/control problem, not the washer-dryer HC2 drying-heater condition.
Samsung uses LC, LC1, LE, LE1, and related displays for a water-level or leakage condition on supported washers. Look for moisture first, inspect visible supply and drain hoses, and run an empty no-additive test to identify excess detergent foam.
The LC1 display on many Samsung washing machines indicates that water was detected in the washer base. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The LO display on many Samsung washing machines indicates that the door failed to unlock. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The nd display on many Samsung washing machines indicates that the washer did not drain. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The nF display on many Samsung washing machines indicates that the washer did not fill with water. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The OC / OE display on many Samsung washing machines indicates that the washer detected an overfill. Codes can vary by model, so match the full model number to the official manual before ordering parts.
Samsung defines PC (also PE on some models) as a clutch-position error: the washer cannot determine the clutch's position. This is distinct from PC1, where a clutch position was detected but the Hall-sensor signal is then abnormal.
Samsung defines PC1 (also PE1 on some models) as an abnormal clutch Hall-sensor signal after the clutch position has already been detected. That makes PC1 a feedback-signal fault rather than the basic 'position cannot be detected' PC condition.
Samsung lists SF, along with 5F and SF1/SF2/SF3 variants, as a washer system error. Unlike 2E, which Samsung places in the voltage-error family, SF does not have a normal external plumbing or load-balancing fix; Samsung's user-level path is a brief power reset followed by service if the error returns.
The tC / tE display on many Samsung washing machines indicates that the temperature sensor signal is abnormal. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The UC display on many Samsung washing machines indicates that the power supply voltage is unstable. Codes can vary by model, so match the full model number to the official manual before ordering parts.
The UE / Ub display on many Samsung washing machines indicates that the load is unbalanced for spinning. Codes can vary by model, so match the full model number to the official manual before ordering parts.
On supported Samsung FlexWash and washer-dryer combo families, HC2 points to the drying-heater system rather than the normal wash-water heater. Samsung's FlexWash guidance says to power-cycle once and seek service if HC2 returns.
A letter can resemble a number on a segmented display, and spaces or separators can change the diagnosis. Photograph the display before clearing it, note when it appears, and compare the complete model identifier with official Samsung support.
Troublio groups codes by both brand and device so a meaning from a dryer, dishwasher, washer, or printer is not applied to the wrong product. Every linked guide includes likely causes, checks in order, stop conditions, model warnings, and available official references.
