Is your Samsung dishwasher unexpectedly showing an LC code? You’re not alone. This error code indicates a possible leak or overflow detection within the dishwasher, and it often catches homeowners off guard. While it can be a troublesome issue, there are practical steps you can take to troubleshoot the situation. In this guide, you’ll learn what causes the LC code, how to get your dishwasher working again, and when it’s time to consult professionals for ultimate peace of mind.

Key Takeaways

When your Samsung dishwasher displays the LC code, it suggests the appliance has detected water in the lower tray or a potential leak. Checking common leak points, cleaning the area thoroughly, and resetting your dishwasher can often resolve the problem. If your efforts don’t solve the issue, rely on an experienced team that can swiftly locate leaks and fix them for good.

What Causes the Samsung Dishwasher LC Code?

The LC code is designed to alert you to the presence of moisture or a leak within the dishwasher’s base. There are several reasons why this code might appear:

• Accumulated Water in the Base: Drips or spills from a loose hose or a damaged seal can gather in the dishwasher’s leak tray.
• Clogged or Damaged Drain Components: A blocked drain hose or clogged filter can lead to excess water pooling at the bottom of the unit.
• Faulty Door Seal: A worn-out or cracked door gasket can let water seep onto the dishwasher’s lower tray, triggering the sensor.
• Defective Water Supply Valve: Small drips from a faulty inlet valve may slowly fill the tray, eventually triggering the LC code.
• Malfunctioning Sensor or Circuit Board: In rarer cases, the sensor itself or the control board may be at fault, falsely detecting water where there is none.

Step-by-Step Guide to Address the Samsung Dishwasher LC Code

1. Disconnect the Dishwasher
   

   Turn off the power supply at the circuit breaker or unplug the dishwasher. This step ensures your safety and helps reset the dishwasher’s systems.

2. Access the Lower Panel
   

   Remove the front kick plate or toe panel at the bottom of your dishwasher. This allows you to inspect the base and quickly spot any standing water.

3. Dry Up Excess Water
   

   If you see pooled water in the tray, carefully absorb it with a towel or sponge. Ensure the area is thoroughly dry, so the sensor no longer detects moisture.

4. Check for Visible Leaks
   

   Inspect the water inlet valve, drain hoses, sump, pump, and all connections. Look for cracks, loose clamps, or damaged seals. Even small leaks can trigger the LC code.

5. Clean the Filters and Spray Arms
   

   Remove and rinse the dishwasher filter with warm water to clear out debris. Examine the spray arms for blockages or cracks that might direct water toward the door seams.

6. Secure the Door Gasket
   

   Wipe the door seal and check for signs of wear or cracking. If the gasket is dirty or misaligned, it could fail to create a proper seal, causing water to escape.

7. Reset the Dishwasher
   

   Restore power to your dishwasher. In many cases, once the water is removed and any leaks are addressed, the LC error will clear on its own. If the error persists, proceed with further troubleshooting or consult a professional technician.

8. Test a Short Cycle
   

   Run a short rinse cycle to confirm whether the LC code returns. Monitor the dishwasher carefully for leaks during the cycle. If you spot water accumulating, turn off the dishwasher and investigate further.
