If your Samsung washer stops mid-cycle and shows a code on the display, that code is usually the machine’s way of pointing you toward the problem area. Some Samsung washer error codes are related to water supply, some point to draining issues, and others involve balance, door locking, or sensors.
This guide brings together the most common Samsung Washer Error Codes in one place so you can understand what each code usually means and what to check first. If you want to compare Samsung faults with another brand, you can also return to the Washer Code Guide homepage for broader navigation.
Most Common Samsung Washer Error Codes
Here are some of the most common Samsung washer error codes users run into:
- 4C – Water supply problem
- 5C – Drain problem
- DC – Door or load balance problem, depending on model
- UR – Unbalanced load
- LC – Leak or water level issue on some models
- UB – Unbalanced load
- OC – Overflow condition
- 1C – Water level sensor issue
- 3C – Motor-related issue on some models
Each code can behave a little differently depending on the washer model, but the list below covers the usual meaning and the first things to check.
Samsung Washer 4C Code
The 4C code usually means the washer is not getting enough water, or it is taking too long to fill. In many cases, the cause is something simple such as closed water valves, bent inlet hoses, or clogged inlet screens.
Common causes of Samsung 4C code
- Water supply valves are closed
- Inlet hose is bent or restricted
- Low water pressure
- Dirty inlet screens
Make sure both supply valves are fully open and check the hoses for bends or blockage.
Samsung Washer 5C Code
The 5C code usually points to a drain problem. The washer is unable to remove water from the tub within the expected time.
Common causes of Samsung 5C code
- Blocked drain filter
- Kinked drain hose
- Drain pump issue
- Household drain restriction
Start by cleaning the drain filter and checking whether the hose is blocked or installed incorrectly.
Samsung Washer DC Code
The DC code often relates to the washer door or load condition, depending on the model. On some machines it appears when the door is not securely closed, while on others it may be tied to an imbalance during spin.
Common causes of Samsung DC code
- Door not fully closed
- Clothing caught in the door area
- Unbalanced load
- Latch or switch issue
Check the door first, then inspect the load balance if the code appears during spin.
Samsung Washer UR Code
The UR code usually means the washer has detected an unbalanced load. This often happens when a heavy item shifts to one side of the drum or when the machine cannot balance the load properly before spinning.
Common causes of Samsung UR code
- Uneven laundry distribution
- Single bulky item in the drum
- Washer not level
- Suspension issue in some cases
Redistribute the load and make sure the washer is level on the floor.
Samsung Washer LC Code
The LC code is commonly related to a leak condition or water-level issue on some Samsung models. The washer may detect water where it should not, or it may believe there is a leak-related risk.
Common causes of Samsung LC code
- Leak detection issue
- Hose connection problem
- Water remaining in the base area
- Sensor fault in some cases
Check for visible leaking, loose hose connections, or signs of moisture around the washer.
Samsung Washer UB Code
The UB code also points to an unbalanced load. It is very similar to UR in practical use and often appears when the drum cannot stabilize the load for a proper spin.
- Unbalanced laundry load
- Single heavy item
- Washer out of level
Samsung Washer OC Code
The OC code usually indicates an overflow or overfill condition. This can happen when too much water enters the tub or the washer cannot control the water level properly.
- Water inlet valve stuck open
- Water level sensor problem
- Control issue
Samsung Washer 1C Code
The 1C code is often related to the water level sensor. The washer may be having trouble reading the amount of water inside the tub accurately.
- Water level sensor issue
- Wiring fault
- Control problem
Samsung Washer 3C Code
The 3C code is commonly linked to a motor-related problem on some models. The washer may detect abnormal motor operation, speed issues, or resistance during drum movement.
- Motor problem
- Wiring issue
- Overload condition
- Control board fault
How to Reset a Samsung Washer
Sometimes a Samsung washer error code is caused by a temporary control glitch. A simple reset is worth trying before assuming the washer needs repair.
- Turn the washer off
- Unplug it from power
- Wait about 5 minutes
- Plug it back in
- Restart a short cycle
A reset can clear temporary interruptions, but it will not fix a blocked hose, failed pump, faulty sensor, or broken latch.
When a Samsung Washer Error Code Needs Service
Some Samsung washer codes are tied to basic user-correctable issues such as closed water valves, an unbalanced load, or a clogged filter. Others may involve sensors, motors, control systems, or water-level faults that require deeper testing.
You may need service if:
- The same code keeps returning after troubleshooting
- The washer will not fill, drain, spin, or lock correctly
- You hear unusual noises from the pump or motor
- The machine shows overflow or leak symptoms
- A reset does not help at all
FAQ
What is the most common Samsung washer error code?
Many users commonly see 4C, 5C, UR, and DC codes. These are often related to water supply, drain flow, door closure, or load balance.
Can I reset a Samsung washer error code?
Yes, sometimes a reset clears a temporary control issue. But if the code returns, the real cause still needs attention.
Are UR and UB the same on a Samsung washer?
They are both closely related to load imbalance and spin stability, though the exact display can vary by model.
Final Thoughts
Samsung Washer Error Codes help narrow down the problem area, even if they do not always identify the exact failed part. Codes like 4C and 5C often come from basic flow problems, while codes like 1C, 3C, and OC can point to more technical faults.
Start with the basics first: water supply, drain path, load balance, door closure, and a full reset. If the same Samsung washer error code keeps coming back, the machine may need closer diagnosis or professional repair.
