The Samsung Washer OC Code usually indicates an overflow condition. The washer believes too much water has entered the tub or that the water level has exceeded the safe operating range.
To prevent flooding and potential damage, Samsung washers may stop the cycle, activate the drain pump, and display the OC error code. If you’re troubleshooting multiple Samsung washer faults, visit our complete Samsung Washer Error Codes List.
Quick Answer: What Does Samsung Washer OC Code Mean?
On most Samsung washers, the OC code means the machine detects an excessive water level inside the tub. This can happen because water is entering too quickly, the water level sensor is reporting incorrect information, or the control system cannot properly regulate filling.
Unlike the Samsung Washer LC Code, which focuses on leak detection, the OC code focuses on excessive water inside the washer.
Most Common Causes of Samsung Washer OC Code
- Faulty water inlet valve
- Defective water level sensor
- Pressure hose blockage
- Control board malfunction
- Water inlet valve stuck open
- Sensor communication issue
Symptoms That Often Accompany an OC Error
- The tub fills with too much water
- The drain pump runs unexpectedly
- The cycle stops before washing begins
- The washer repeatedly drains water
- The OC code appears shortly after filling starts
What to Check First
1. Observe the Water Level
If the tub continues filling after reaching a normal level, the inlet valve may be stuck open.
2. Inspect the Water Inlet Valve
A faulty inlet valve can allow water to enter the washer even when power is removed.
3. Check the Water Level Sensor
The pressure sensor helps the washer determine how much water is in the tub. Incorrect readings may trigger an OC error.
4. Examine the Pressure Hose
A blocked or damaged pressure hose can prevent accurate water-level detection.
How to Fix Samsung Washer OC Code
- Turn off the water supply temporarily.
- Inspect the inlet valve.
- Check the water level sensor.
- Inspect the pressure hose.
- Run a test cycle after repairs.
Many OC errors are caused by filling-system components rather than major mechanical failures.
DIY Repair Cost Guide for Samsung Washer OC Code
| Repair Step | Estimated Cost |
|---|---|
| Inspect Pressure Hose | $0 |
| Check Water Level Sensor | $0 |
| Clean Pressure Hose | $0 |
| Replace Water Inlet Valve | $20 – $60 |
| Replace Water Level Sensor | $25 – $80 |

How to Reset a Samsung Washer After an OC Error
- Turn the washer off.
- Unplug it from power.
- Wait approximately 5 minutes.
- Plug it back in.
- Start a short rinse cycle.
A reset may clear temporary electronic faults but will not correct a defective valve or sensor.
When the Samsung Washer OC Code Keeps Returning
- Faulty water inlet valve
- Failed water level sensor
- Blocked pressure hose
- Control board malfunction
- Electrical communication issue
If the washer reports a leak condition instead of an overflow condition, review the Samsung Washer LC Code guide. If the issue involves insufficient water entering the machine, see the Samsung Washer 4C Code troubleshooting guide.
