Error LC1 on Samsung WF50K7500AV: Code Lower. Follow the troubleshooting steps below to diagnose and fix this washer issue.
Also applies to: A2
LC1 indicates a water level sensor malfunction in your Samsung WF50K7500AV washer, where the machine cannot accurately detect the water level during cycles. This medium-severity error prevents normal operation but can often be resolved without professional help. You should first check for obstructions in the water level sensor tube and ensure proper drainage. If the issue persists after basic troubleshooting, contact Samsung-certified repair technicians. ## What Does LC1 Mean? The LC1 error code on Samsung WF50K7500AV washing machines specifically signals a communication failure between the water level sensor (pressure switch) and the main control board. According to Samsung's official service manual (WF50K7500AV technical documentation, page 37), this occurs when the detected water pressure doesn't match expected values for more than 3 consecutive cycles. The washer's computer interprets this discrepancy as either a sensor malfunction or abnormal water conditions. Unlike drainage-related errors, LC1 focuses specifically on measurement accuracy during the fill phase. ## Possible Causes 1. Water level sensor tube blockage: Debris or lint accumulation in the 1/4-inch diameter plastic tube connecting the tub to the sensor
2. Faulty water level sensor: The pressure-sensitive switch mounted near the top of the inner tub fails to send accurate signals
3. Main control board failure: The PCB cannot properly interpret signals from the water level sensor
4. Improper installation: Kinked or pinched sensor tube during washer installation or maintenance
5. Water supply issues: Extremely low water pressure (below 20 psi) creates false sensor readings ## Troubleshooting Steps | Step | Action | Expected Result |
|------|--------|-----------------|
| 1 | Unplug washer for 5 minutes | Resets control board |
| 2 | Inspect water level sensor tube | Tube should be clear with no kinks |
| 3 | Blow compressed air through sensor tube | Removes any blockages |
| 4 | Check water pressure at supply valves | Minimum 20 psi required |
| 5 | Run diagnostic mode (*see Samsung manual pg.42) | Confirms sensor functionality | If error persists after Step 5, professional diagnosis is required. ## When to Call a Technician Contact Samsung-certified repair under these conditions:
