Samsung Washer Error Codes List: Meanings, Causes, and How to Fix Them
If your Samsung washer suddenly stops during a cycle and displays an error code, the code is designed to help identify the area causing the problem. Samsung washing machines use diagnostic codes to alert users to issues involving water supply, drainage, load balance, door locking, sensors, motors, and other internal components.
Understanding what these Samsung washer error codes mean can help you determine whether the problem is something simple you can fix yourself or an issue that requires professional repair. In many cases, common washer faults are caused by clogged filters, blocked hoses, unbalanced loads, or temporary control board glitches.
This guide covers the most common Samsung washer error codes, explains their meanings, and links to detailed troubleshooting guides for each code.
Most Common Samsung Washer Error Codes
- Samsung Washer 4C Code – Water supply problem.
- Samsung Washer 5C Code – Drainage problem.
- Samsung Washer DC Code – Door lock or load issue.
- Samsung Washer UB Code – Unbalanced load detected.
- Samsung Washer UR Code – Spin imbalance problem.
- Samsung Washer LC Code – Leak detection warning.
- Samsung Washer OC Code – Overflow condition.
- Samsung Washer 1C Code – Water level sensor issue.
- Samsung Washer 3C Code – Motor-related fault.
Samsung Washer 4C Code
The Samsung 4C code usually indicates a water supply problem. The washer is not receiving enough water or is taking too long to fill.
Common causes include:
- Water supply valves turned off
- Kinked or blocked inlet hoses
- Low household water pressure
- Clogged inlet filter screens
- Faulty water inlet valve
Before replacing any parts, check that both hot and cold water valves are fully open and inspect the inlet hoses for restrictions.

Samsung Washer 5C Code
The Samsung 5C code typically points to a drainage problem. The washer cannot remove water from the tub within the expected time.
Common causes include:
- Blocked drain filter
- Clogged drain hose
- Drain pump failure
- Household drain restriction
- Improper drain hose installation
Cleaning the drain filter is often the first and most effective troubleshooting step.

Samsung Washer DC Code
The Samsung DC code is commonly associated with door lock or load balance issues, depending on the washer model.
Possible causes include:
- Door not fully closed
- Clothing trapped in the door seal
- Unbalanced load
- Faulty door latch
- Door switch problems
Check the door first and redistribute the laundry if the code appears during the spin cycle.
Samsung Washer UB Code
The UB code indicates an unbalanced load condition. The washer has detected that the laundry inside the drum is not evenly distributed.
Common causes include:
- Heavy items gathered on one side
- Single bulky item washing alone
- Washer not level
- Suspension component wear
Redistributing the load often resolves the problem immediately.
Samsung Washer UR Code
The Samsung UR code is closely related to load balancing and spin stability. It usually appears when the washer cannot properly balance the drum before entering a high-speed spin cycle.
Common causes include:
- Uneven laundry distribution
- Oversized items
- Washer installation issues
- Suspension or leveling problems
The first step is always to pause the cycle and rearrange the clothing inside the drum.
Samsung Washer LC Code
The Samsung LC code generally indicates a leak detection or water level issue. Depending on the model, the washer may detect moisture in an area where water should not be present.
Possible causes include:
- Leaking hoses
- Loose hose connections
- Water accumulation inside the base
- Leak sensor malfunction
- Control board issues
Inspect all visible water connections and check for signs of moisture around the machine.
Samsung Washer OC Code
The Samsung OC code usually points to an overflow condition. The washer believes too much water is entering the tub or the water level is exceeding safe limits.
Common causes include:
- Stuck water inlet valve
- Faulty pressure sensor
- Water level sensor problems
- Control board malfunction
If the tub continues filling unexpectedly, turn off the water supply and unplug the washer.
Samsung Washer 1C Code
The Samsung 1C code is commonly associated with the water level sensor system.
Possible causes include:
- Faulty pressure sensor
- Damaged wiring
- Sensor communication issue
- Control board problem
This code often requires additional testing if basic troubleshooting does not solve the issue.
Samsung Washer 3C Code
The Samsung 3C code is generally related to motor operation. The washer detects abnormal drum movement, motor speed irregularities, or excessive resistance during operation.
Common causes include:
- Motor fault
- Wiring issue
- Drum overload
- Control board malfunction
If the washer struggles to rotate the drum or stops unexpectedly, the motor system should be inspected.
How to Reset a Samsung Washer
Some Samsung washer error codes are caused by temporary electronic glitches. Before assuming a component has failed, try a basic reset procedure.
- Turn the washer off.
- Unplug the power cord.
- Wait approximately five minutes.
- Plug the washer back in.
- Start a short cycle.
A reset can clear temporary software-related issues but will not repair mechanical failures or blocked components.
When to Call a Technician
Many Samsung washer error codes can be resolved through basic troubleshooting. However, professional service may be necessary if:
- The same error code returns repeatedly
- The washer will not fill or drain
- The drum will not spin properly
- The door refuses to lock
- Water leaks are present
- The motor fails to operate
- A reset does not solve the issue
Persistent faults often indicate a failed component that requires testing or replacement.
Frequently Asked Questions
What is the most common Samsung washer error code?
The most commonly reported Samsung washer codes include 4C, 5C, DC, UB, and UR. These are usually related to water supply, drainage, door closure, and load balancing.
Can I reset a Samsung washer error code?
Yes. Unplugging the washer for several minutes can clear temporary control board errors. However, the underlying cause must still be corrected if the code returns.
Are UR and UB the same error?
They are closely related and both involve load imbalance conditions. The exact behavior depends on the washer model.
Is the 4C code serious?
Not usually. Most 4C errors are caused by water supply restrictions, closed valves, or clogged inlet screens.
Final Thoughts
Samsung washer error codes provide valuable clues about what is preventing the machine from operating correctly. Codes such as 4C and 5C often point to simple maintenance issues, while codes like 1C, 3C, and OC may involve sensors, motors, or internal control systems.
Start with the basic checks first, including water supply, drainage, load balance, door closure, and a full reset. If the same Samsung washer error code continues appearing after troubleshooting, a more detailed diagnosis or professional repair may be required.
