Error Code: 1C Difficulty: Moderate
Problem: Water level sensor error or leak detected
How to Fix 1C Error
- UNPLUG THE WASHER. This code indicates a water level sensor error or, less commonly, a leak.
- First, check for any signs of a water leak under the machine. If a leak is found, the leak sensor has been tripped and the source of the leak must be found and repaired.
- If there is no leak, the water level sensor (pressure switch) has likely failed. It is usually located near the top of the tub, accessible by removing the top panel of the washer. It has a thin air tube connected to it.
- Disconnect the wire harness and the air tube from the old sensor. Check the tube for blockages or kinks. Remove the old sensor and install the new one.
- Securely reattach the air tube and wire harness, then reassemble the washer.
Samsung Washer 1C Checks Before Replacing Parts
- Restart the washer and confirm the 1C message returns under the same condition instead of after a one-time interruption.
- Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability.
- Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed.
- Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
- If the 1C code points to a specific system, test that system directly before ordering replacement parts.

If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
