If your Samsung dishwasher displays an LC or LE error code, it’s signaling that the appliance has detected moisture or a leak in the base pan or near the moisture sensor. This safety feature is designed to prevent water damage by automatically stopping the wash cycle and activating the drain pump.
🔍 What the LC Code Means
According to Samsung and multiple appliance repair sources, the LC (or LE) code indicates that the dishwasher’s leak sensor has detected water where it shouldn’t be — typically in the bottom tray of the machine.
This doesn’t always mean there’s an actual leak; sometimes, excess moisture, soap suds, or condensation can trigger the sensor.
In short:
The LC code = the dishwasher thinks there’s a leak, so it stops working to protect your home.

⚠️ Common Causes of the LC Error Code
Here are the most frequent reasons this error appears:
- Actual water leak from hoses, the door seal, or the sump.
- Excess detergent or suds causing overflow or sensor moisture.
- Moisture in the base pan after recent installation or cleaning.
- Clogged or misaligned drain hose leading to backflow.
- Faulty leak sensor or control board malfunction (less common).
🧰 How to Fix the Samsung Dishwasher LC Code
Follow these steps to diagnose and clear the error:
1. Unplug and Dry the Dishwasher
- Turn off power at the circuit breaker or unplug the dishwasher.
- Let it sit for 24–48 hours to allow any trapped moisture to dry.
- You can also use a fan or hair dryer (on low heat) to speed up drying around the base.
2. Inspect for Leaks
- Remove the bottom kick plate and check for standing water.
- Examine hoses, the door gasket, and the sump area for drips or cracks.
- Tighten any loose connections.
3. Check the Detergent
- Too much or the wrong type of detergent can cause excessive suds.
- Use only dishwasher-specific detergent and follow the recommended amount.
4. Reset the Dishwasher
- After drying and checking for leaks, restore power.
- Run a short cycle to test if the code clears.
5. Call for Service if the Code Persists
If the LC code remains or the dishwasher won’t turn off, it could indicate a stuck relay or control board issue — in that case, cut power immediately and contact a qualified technician.

🧼 How to Prevent the LC Code in the Future
- Avoid overfilling the dishwasher with detergent.
- Regularly clean the filter and drain area.
- Make sure the dishwasher is level to prevent water pooling.
- Periodically inspect hoses and seals for wear.
- Run a maintenance cycle with vinegar to reduce buildup and moisture.
🧾 Summary
| Problem | Cause | Solution |
|---|---|---|
| LC/LE Code | Leak or moisture detected | Dry the base, inspect for leaks |
| Dishwasher won’t stop running | Control board or relay issue | Cut power, call technician |
| Code reappears after drying | Faulty sensor or persistent leak | Professional diagnosis |
Final Thoughts
The Samsung dishwasher LC code is primarily a safety alert, not necessarily a sign of a major failure. In most cases, drying out the base and addressing minor leaks or detergent issues will clear the error. However, if the problem persists, it’s best to contact Samsung support or a certified appliance repair technician to prevent further damage.
