TROUBLESHOOTING

Samsung Appliance Error Codes

Washing Machine

Front-load, top-load, and FlexWash washer codes for leakage, filling, draining, overflow, door lock, load balance, and sensor systems.

1E / LE /
1C / LC
Water Level or Leakage Error
Moisture was detected where it should not be, or the level sensor is reporting a leak-related problem
Severity:HIGH
Inspect for leaks
What This Means
Samsung uses 1E, LE, 1C, LC, and related variants when moisture is detected somewhere it does not belong or the washer thinks there is a leakage or water-level problem.
Common Causes
  • Small external or internal water leak
  • Kinked drain or supply hose
  • Excess suds from too much detergent
  • Water-level sensor issue
What You Can Try
Look carefully for any sign of leaking water, check that the hoses behind the washer are not kinked, and run an empty cycle with no additives to see if leftover suds are triggering the code. If there is no visible leak and the code returns, service is likely needed.
4C / nF /
4E
Not Filling Error
The washer is not getting incoming water correctly
Severity:MEDIUM
DIY possible
What This Means
4C, nF, and 4E mean water is not entering the washer correctly during the fill portion of the cycle.
Common Causes
  • Supply valves turned off
  • Hot or cold hose connected incorrectly
  • Bent or kinked fill hose
  • Low pressure or inlet-valve issue
What You Can Try
Make sure both supply valves are fully open, confirm the hoses are connected to the correct inlets, and inspect the hoses for kinks. Restore power and retry after a short reset if needed.
5E / SE /
5C / SC
No Drain Error
The washer cannot drain water at the correct speed, or at all
Severity:MEDIUM
DIY possible
What This Means
Samsung uses 5E, SE, 5C, and SC when the washer is not draining water properly.
Common Causes
  • Blocked or kinked drain hose
  • Debris in the drain path
  • Drain pump trouble
  • Drain setup issue
What You Can Try
Check the drain hose for kinks or clogs, clean any accessible filter or trap, and retry the cycle. If the washer still cannot pump out water, the drain pump may need service.
OE / 0E /
OC / 0C
Overflow Error
The washer has detected too much water in the tub
Severity:HIGH
Turn water off
What This Means
These overflow codes mean there is too much water in the washer.
Common Causes
  • Stuck inlet valve letting water continue to enter
  • Drain problem causing water to remain in the tub
  • Water-level sensing problem
  • Control issue
What You Can Try
Stop the cycle, unplug the washer, and shut off the water supply if the tub continues filling. Because overflow can quickly become a leak problem, do not keep retrying the machine if the code comes back right away.
dE / dC /
dL
Door Error
The washer does not detect the door as closed and locked
Severity:MEDIUM
DIY possible
What This Means
dE, dC, dL, and related door codes mean the washer does not think the door is shut and locked securely.
Common Causes
  • Laundry caught in the door opening
  • Door not fully closed
  • Latch or switch problem
  • Damage around the door strike

Ub / UE /
Ur
Unbalanced Load Error
The load is uneven inside the tub and the washer cannot complete spin normally
Severity:INFO
DIY possible
What This Means
Ub, UE, and similar codes mean the load is unbalanced. A Ur code is usually an unbalanced-load retry and does not mean the washer itself is faulty.
Common Causes
  • Single heavy item washing alone
  • Bulky load tangled on one side
  • Load too small to balance well
  • Washer not level
What You Can Try
Pause the cycle, redistribute the laundry, and restart. If the washer shows balance errors often with normal loads, check that it is level and stable on the floor.
SUd / Sd /
5Ud
Excessive Suds Error
The washer has detected oversudsing and pauses to let the foam settle
Severity:INFO
DIY possible
What This Means
Suds-related codes mean the washer has detected too much foam. Samsung notes this is usually caused by detergent use rather than a failed part.
Common Causes
  • Too much detergent
  • Non-HE detergent in an HE washer
  • Detergent buildup from previous cycles
What You Can Try
Let the washer complete its pause and recovery. For future loads, use less HE detergent. If heavy suds remain in the machine, run empty rinse cycles until the foam is gone.
