Understanding the LC Error Code
The LC error code on a Samsung dishwasher stands for “Leakage Error.” This code is triggered when the dishwasher¡¯s built-in leak sensor detects water or moisture where it shouldn¡¯t be¡ªtypically in the base pan beneath the unit. As a safety feature, the dishwasher halts its operation and may activate the drain pump to prevent water damage to your kitchen. According to Samsung¡¯s official support page, “if you are receiving the error codes LE or LC, it indicates that moisture is detected where it doesn’t belong, even if a leak isn’t visible or noticeable” [(( Samsung Official Support ))].
The presence of the LC code doesn¡¯t always mean there¡¯s a dramatic flood under your dishwasher. Sometimes, it¡¯s a small amount of water¡ªSamsung notes that the leak sensor can detect as little as 10 milliliters (about two teaspoons)¡ªor even a false alarm due to humidity or a damp sensor. Understanding this code is the first step to diagnosing whether it¡¯s a minor hiccup or a sign of a more serious issue.

Common Causes of the LC Error Code
Several factors can trigger the LC error code on a Samsung dishwasher. Identifying the root cause is key to fixing the problem efficiently. Here¡¯s a breakdown of the most common reasons, compiled from expert sources and user experiences:
1. Actual Water Leakage
The most straightforward cause is an actual leak. This could stem from damaged components like hoses, seals, or the water inlet valve. “If you can see water on the floor around the dishwasher, it is safe to assume a component needs to be replaced to fix the problem,” explains a repair guide from Dan Marc Appliance [(( Dan Marc Appliance ))]. Leaks might occur at the door, under the unit, or near the water supply connections.
2. Faulty or Misaligned Door Seals
A worn-out or misaligned door gasket can allow water to escape during a cycle. “If the door gasket fails, water can leak into the underside of the dishwasher and trigger the LC error,” notes iFixit¡¯s troubleshooting page. This might not always result in a puddle on the floor but can still activate the sensor.
3. Clogged or Damaged Hoses
A blocked or cracked drain hose can prevent proper drainage, causing water to back up and spill into the base pan. HomeGearGeek states, “A clogged or blocked drain hose can prevent water from draining properly. When water accumulates in the dishwasher, it can trigger the LC error code.”
4. Overfilled Detergent Dispenser
Using too much detergent can create excessive suds, which the leak sensor might interpret as moisture. “If you¡¯ve been using too much detergent, excess may linger in the dishwasher¡¯s system,” warns Samsung Gulf, suggesting that this moisture can falsely trigger the LC code.
5. Sensitive or Faulty Leak Sensor
Sometimes, the issue isn¡¯t a leak but a hypersensitive or malfunctioning sensor. “If there isn¡¯t a visible leak, then water may have splashed onto the moisture sensor if you recently moved it,” explains WikiHow. High humidity or condensation in cold environments can also trick the sensor into detecting water.
6. Installation Issues
If the dishwasher isn¡¯t level or was recently installed, water might pool improperly or splash onto the sensor. For instance, failing to remove the knockout plug from a garbage disposal connection can cause drainage issues, leading to the LC code.

Troubleshooting the LC Error Code
When faced with the LC error code, you don¡¯t need to panic¡ªmany cases can be resolved with some basic troubleshooting. Here¡¯s a step-by-step guide to diagnosing and fixing the issue, drawing on advice from authoritative sources:
Step 1: Power Down and Inspect for Visible Leaks
Start by turning off the dishwasher at the circuit breaker or unplugging it for safety. “Turn off the dishwasher and disconnect it from the power source. This step ensures your safety during the troubleshooting process,” advises HomeGearGeek. Inspect the floor around the dishwasher, under the unit, and around the water supply and drain hoses for any signs of water. If you see a puddle, note its location¡ªthis can hint at the leak¡¯s source.
Step 2: Reset the Dishwasher
A simple reset can clear temporary glitches. “Unplug it (or turn off power at the circuit breaker), wait some time for the electrical charge to clear out of the dishwasher (usually 1 to 5 minutes at most), and then power it up again,” says Samsung¡¯s official troubleshooting guide. Run a test cycle afterward to see if the code disappears.
Step 3: Check the Door Seal
Examine the rubber gasket around the door for wear, tears, or misalignment. “The rubber seal can be pulled out of alignment at times. If this occurs, simply push it back into the channel,” suggests Samsung Gulf. Clean it with a mild soap and a towel to remove debris that might prevent a tight seal.
Step 4: Inspect Hoses and Connections
Look at the water supply hose and drain hose for cracks, kinks, or loose connections. “Check the connections at both ends, and look for and feel for moisture,” recommends Samsung¡¯s support page. If you find damage, replace the hose¡ªdrain hoses are inexpensive and widely available.
Step 5: Dry the Base Pan and Sensor
If no leak is visible, moisture in the base pan might be the culprit. Remove the kick plate (the panel near the floor) and use a towel or rag to dry the pan and the leak sensor, typically located at the bottom of the unit. “Dry the sensor and bottom dishwasher pan with a rag. Make sure you get as much of the moisture or water as you can,” advises HowToFixIt.net [(( HowToFixIt.net ))]. You might need to slide the dishwasher out slightly to access this area.
Step 6: Test Detergent Levels
Ensure you¡¯re using the correct amount of detergent. “Detergent is moist enough to activate the moisture sensor and cause the error, and it doesn¡¯t evaporate away and dry as quickly as water does,” notes Samsung Gulf. Clean the detergent dispenser and use pre-measured pods or the recommended amount to avoid excess suds.
Step 7: Check for Installation Issues
Verify that the dishwasher is level using a spirit level. If the front is lower than the back, adjust the leveling legs. Also, if connected to a garbage disposal, ensure the knockout plug has been removed, as this can block drainage and trigger the LC code.
Step 8: Run a Test Cycle
After addressing potential issues, plug the dishwasher back in and run a short cycle. If the LC code persists, it might indicate a faulty component¡ªlike the leak sensor, water inlet valve, or pump¡ªthat requires professional attention.

When to Call a Professional
While many LC issues can be fixed at home, some scenarios call for expert help. If you¡¯ve tried the steps above and the code keeps returning, or if you suspect a faulty sensor or internal component (like the pump or inlet valve), contact a qualified technician. “If you are uncertain about the cause of the LC error code or do not feel confident in resolving the issue, it is advisable to contact a qualified technician,” suggests HomeGearGeek. Samsung also recommends scheduling service if the error persists after basic troubleshooting [(( Samsung Community ))].

Preventative Measures to Avoid the LC Error
To minimize the chances of seeing the LC code again, adopt these proactive habits:
- Regular Inspections: Check hoses, seals, and the base pan periodically for wear or moisture buildup.
- Proper Detergent Use: Stick to manufacturer-recommended amounts to avoid suds-related issues.
- Level Installation: Ensure the dishwasher remains level over time, as settling floors can shift it.
- Clean Filters and Arms: Keep spray arms and filters clear of debris to maintain proper water flow.
- Avoid Overloading: Load dishes evenly to prevent water from splashing out of the tub.
“By using a water softener, you can help prevent mineral buildup in the dishwasher, leading to leaks,” adds Ryujin Ramen in Brooklyn, highlighting the role of water quality in appliance longevity.
