Samsung Dishwasher Error Code LC: Troubleshooting Guide

The Logic Verdict

My Take: The LC error is a safety feature designed to prevent flooding. It means the moisture sensor in the bottom pan has detected water. The video shows that this can sometimes be a false alarm caused by a spill or a temporary glitch, but it often requires drying out the base pan. The author’s method of tipping the unit to access and dry the sensor is a practical DIY solution.

What It Means

The LC error code (often displayed as LE on some models) stands for Leak Check. The dishwasher’s leak sensor, located in the bottom drip pan, has detected moisture. When this happens, the dishwasher will typically drain continuously and refuse to start a new cycle to prevent water damage.

Common Causes

1. Actual Leak: A loose hose, bad seal, or cracked tub leaking water into the base pan.
2. External Spill: Water spilled near the dishwasher that seeped underneath.
3. Moisture Buildup: Excess condensation or a small leak that accumulated over time.
4. Sensor Glitch: A temporary error that can sometimes be cleared with a power reset.

Step-by-Step Fix

1. Power Reset

First, try to reset the system.

• Locate your home’s circuit breaker panel.
• Flip the breaker for the dishwasher OFF, wait 60 seconds, and flip it back ON.
• If the code clears, it might have been a glitch. If it returns immediately or after a cycle, proceed to the next steps.

2. Check Filters and Seals

• Remove the bottom rack and inspect the drain filter. Clean it if it’s dirty.
• Check the door seal (gasket) for any tears or food debris that might cause a leak.

3. Inspect the Bottom Pan (The Fix)

If the code persists, there is likely water in the bottom pan triggering the sensor.

• Turn off Power: Flip the breaker off again.
• Uninstall: Remove the screws securing the dishwasher to the cabinet or countertop (usually at the top or sides).
• Pull Out: Carefully slide the dishwasher out.
• Tip and Drain: The video demonstrates tipping the dishwasher (have towels ready!) or removing the bottom panel to access the sensor.
• Dry the Sensor: Locate the leak sensor on the bottom pan. Use a towel or hair dryer (on low) to ensure the sensor and the pan are completely dry.

4. Verify and Reinstall

• Once dry, slide the dishwasher back into place.
• Run a test cycle. Watch closely for any new leaks appearing under the unit.
• If no leaks appear and the code is gone, it was likely a one-time spill or slow accumulation. If water returns, you have an active leak that needs repair (check hoses and pump connections).
