The Samsung Washer 1C Code usually indicates a water level sensor problem. The washer is having difficulty determining how much water is inside the tub, which can interrupt normal operation and prevent cycles from completing correctly.
Many 1C errors are caused by sensor communication problems, damaged pressure hoses, wiring faults, or a faulty water level sensor. If you’re troubleshooting multiple Samsung washer faults, visit our complete Samsung Washer Error Codes List.
Quick Answer: What Does Samsung Washer 1C Code Mean?
On most Samsung washers, the 1C code means the machine cannot accurately read the water level inside the tub. Without reliable water-level information, the control system cannot safely continue the wash cycle.
Unlike the Samsung Washer 4C Code, which focuses on water entering the machine, the 1C code focuses on monitoring and measuring water levels.
Most Common Causes of Samsung Washer 1C Code
- Faulty water level sensor
- Blocked pressure hose
- Disconnected pressure hose
- Damaged wiring
- Control board issue
- Sensor communication failure
Symptoms That Often Accompany a 1C Error
- The washer stops unexpectedly
- The tub fills incorrectly
- The cycle will not start
- The washer drains unexpectedly
- Water levels appear abnormal
- The 1C code appears repeatedly
What to Check First
1. Inspect the Pressure Hose
The pressure hose connects the water level sensor to the tub. If it becomes blocked or disconnected, incorrect readings may occur.
2. Check for Kinks or Damage
A damaged pressure hose may prevent accurate pressure readings.
3. Inspect Wiring Connections
Loose or damaged wiring between the sensor and control board can trigger a 1C error.
4. Verify Sensor Operation
If all visible components appear normal, the water level sensor itself may be defective.
How to Fix Samsung Washer 1C Code
- Reconnect loose pressure hoses.
- Remove blockages from the pressure hose.
- Inspect wiring connections.
- Replace a faulty water level sensor if necessary.
- Run a test cycle after repairs.
DIY Repair Cost Guide for Samsung Washer 1C Code
| Repair Step | Estimated Cost |

How to Reset a Samsung Washer After a 1C Error
- Turn the washer off.
- Unplug it from power.
- Wait approximately 5 minutes.
- Plug it back in.
- Start a short cycle.
A reset may clear temporary faults but will not repair a failed sensor or damaged hose.
When the Samsung Washer 1C Code Keeps Returning
- Faulty water level sensor
- Pressure hose blockage
- Wiring issue
- Control board malfunction
