Lc Error Meaning
The LC error code on a Samsung dishwasher signals a leak issue. This code appears when the dishwasher detects water where it should not be. Understanding the LC error meaning helps users take quick action. Ignoring this alert can cause more damage to the appliance.
Leak Detection Alert
The LC error is a leak detection alert. It means the dishwasher’s sensor found moisture in the base. This area usually stays dry during normal operation. The sensor triggers the LC code to prevent flooding or electrical problems.
The dishwasher may stop working until the leak is fixed. This safety feature protects your home and dishwasher from serious damage. The alert shows on the display panel as “LC” or “LE” error code.
Common Causes
Many issues can cause the LC error code. A small water leak inside the dishwasher often triggers this alert. The most common reasons include:
- Cracked or damaged door seals that let water escape
- Loose or kinked drain hoses causing leaks
- Clogged or blocked drain pump
- Water pooling in the base pan from spills or overfilling
- Faulty float switch or leak sensor
Checking these parts can help find the leak source. Fixing or replacing damaged components usually clears the error. Drying out the base pan is also important to reset the sensor.

Initial Checks
The LC error code on a Samsung dishwasher signals a water leak or moisture issue inside the appliance. Before calling for repairs, perform some initial checks to find the problem. These simple steps often clear the error and save time.
Start by turning off the power and drying any water that collected in the base pan. Next, remove the bottom rack and any towels or items inside. Use drying techniques to fully evaporate moisture. These actions help reset the dishwasher and stop the error code.
Power Off And Dry Base Pan
First, switch off the dishwasher and unplug it from the power source. Look under the appliance and check the base pan for water. Use a sponge or cloth to soak up all moisture. Drying the base pan is crucial because water triggers the LC error code.
Remove Bottom Rack And Towels
Open the dishwasher door and pull out the bottom rack. Take out any towels or items placed inside to catch leaks. Removing these allows better access to the base pan and helps air flow inside the dishwasher. This step speeds up drying and clearing the error.
Drying Techniques
Use a fan or hairdryer set on low heat to dry the base pan and interior. Avoid high heat as it can damage parts. Let the air circulate for at least 30 minutes to remove all moisture. Complete drying usually clears the LC error and lets the dishwasher work normally again.
Resetting The Dishwasher
Resetting your Samsung dishwasher often resolves the LC error code. This error means the dishwasher detects water leakage or moisture where it should not be. Resetting clears the system and allows it to start fresh. Two simple methods exist to reset the dishwasher safely at home. Follow these steps carefully to avoid damage and restore normal function.
Unplug Method
First, turn off the dishwasher by pressing the power button. Then, unplug the dishwasher from the electrical outlet. Leave it unplugged for about 5 minutes. This pause helps the dishwasher’s internal computer reset. After waiting, plug the dishwasher back in. Turn it on and check if the LC error code has disappeared. This method is quick and does not require tools.
Breaker Reset
Locate the circuit breaker for your dishwasher in the main electrical panel. Switch the breaker off to cut power to the dishwasher. Wait at least 5 minutes to ensure a full reset. Turn the breaker back on to restore power. Start the dishwasher and see if the LC error clears. This method works well if you cannot reach the power cord easily.
Inspecting For Leaks
Leaks often cause the LC error code on Samsung dishwashers. Checking for leaks is a key step to fix this issue. Leaks can come from various parts of the dishwasher. Careful inspection helps find the exact source. This saves time and prevents further damage.
Door Seal Condition
The door seal keeps water inside during washing. Dirt or damage can cause leaks. Wipe the seal clean with a damp cloth. Look for cracks, tears, or stiffness. Replace the seal if it looks worn out. A good seal stops water from escaping.
Hoses And Connections
Hoses carry water in and out of the dishwasher. Loose or broken hoses cause leaks. Check all hose connections at the back. Tighten any loose clamps or fittings. Replace hoses that show cracks or holes. Secure hoses properly to avoid leaks.
Garbage Disposal Link
Dishwashers often connect to the garbage disposal drain. A poor connection here can cause leaks. Inspect the hose linking the dishwasher to the disposal. Make sure the clamp is tight and the hose is intact. Replace damaged hoses or clamps to stop leaks.
Water Inlet Valve
The water inlet valve controls water flow into the dishwasher. A faulty valve may leak water. Look for water around the valve area under the dishwasher. Check the valve for cracks or loose fittings. Replace the valve if it shows damage or leaks.
Detergent Usage
Using the right detergent amount in your Samsung dishwasher is vital to avoid the LC error code. This error often appears due to moisture or leaks inside the machine. Proper detergent usage can prevent excess suds, which may cause leaks or sensor issues.
Choosing a detergent that works well with your dishwasher and adding the correct amount helps maintain smooth operation. Overusing detergent leads to foam buildup. This foam can trigger the LC error by causing water to leak or sensors to malfunction.
Proper Detergent Amount
Measure the detergent carefully before adding it to the dispenser. Most dishwasher detergents have instructions on how much to use per load. Using too much detergent creates excess suds. Too little detergent leaves dishes dirty and may cause the dishwasher to run longer.
Use the amount recommended for your dishwasher size and soil level on dishes. Avoid filling the dispenser beyond the marked line. Regularly check the detergent dispenser for clogs or damage that can affect detergent release.
Avoiding Excess Suds
Excess suds can cause water to leak inside the dishwasher base. This situation triggers the LC error code. Suds also interfere with dishwasher sensors, leading to false error signals.
Use detergents made specifically for dishwashers to reduce sudsing. Avoid using regular dish soap or hand soap, which create too many suds. Rinse dishes before loading to remove food particles that increase suds.
If you notice suds after a wash cycle, run a rinse cycle without detergent to clear them. Keeping suds under control helps prevent leaks and error codes like LC.

Float Switch Check
The float switch plays a key role in your Samsung dishwasher’s safety system. It detects water levels to prevent leaks and flooding. Checking the float switch helps find the cause of the LC error code. This step ensures the dishwasher stops if water rises too high inside.
Start with a careful inspection of the float assembly. It must move freely to work correctly. Any blockage or stuck part can cause false signals. This can trigger the LC error code, even if no water leak exists.
Float Assembly Movement
Locate the float inside the dishwasher tub, usually near the front bottom. Gently lift the float up and down with your fingers. It should move smoothly without resistance or sticking. If the float feels stuck, press it repeatedly to free it. Listen for clicking sounds, which show the switch is activating.
Check the float’s pivot point for dirt or buildup. Clean around it carefully to ensure full movement. A stuck float falsely signals water overflow, causing the LC error code to appear.
Removing Debris
Remove any debris around the float and float switch area. Dirt, food particles, or soap scum can block the float’s path. Use a soft cloth or sponge to wipe the area clean. Avoid sharp tools that might damage the float or switch.
Also, inspect the float switch itself for any visible dirt or corrosion. Clean gently with a damp cloth. After cleaning, test the float movement again to confirm it moves freely. Proper cleaning often clears the LC error and restores dishwasher function.
Replacing Leak Sensor Parts
Replacing leak sensor parts in your Samsung dishwasher is key to fixing the LC error code. The leak sensor detects water leaks inside the machine. Over time, the sensor or its holder can wear out or become damaged. This causes false leak warnings and stops the dishwasher from working properly.
Replacing the leak sensor parts ensures your dishwasher runs smoothly. It also prevents water damage to your kitchen floor. Understanding the components and signs of wear helps you know when to replace the parts.
Leak Sensor Holder
The leak sensor holder keeps the sensor in place inside the dishwasher. It protects the sensor from water and physical damage. A broken or loose holder can cause the sensor to send false leak signals. This leads to the LC error code appearing on your display.
Check the holder for cracks, warping, or loose fittings. Replace it if it shows any damage. A secure holder ensures the sensor works correctly. Use only Samsung-approved parts for the best fit and function.
When To Replace
Replace the leak sensor parts if the LC error code remains after drying the base pan. Also, replace if the sensor or holder looks damaged or worn out. If the dishwasher stops mid-cycle due to leaks, suspect faulty sensor parts.
Signs include water under the dishwasher, frequent LC error codes, or error codes that clear after resetting but return soon. Regular checks help catch problems early. Replacing worn parts keeps your dishwasher leak-free and reliable.
When To Call A Professional
Knowing when to call a professional for your Samsung dishwasher LC error is important. Some issues need expert help to avoid damage. Simple fixes can save time, but persistent problems may require a technician. Understanding the signs helps you decide the right step.
Persistent Error Codes
If the LC error code appears repeatedly after basic resets, it signals a deeper problem. Cleaning and drying the base pan might not be enough. Persistent error codes often mean internal leaks or faulty sensors. Continuing to use the dishwasher can cause more harm. A professional can diagnose and fix these complex issues safely.
Advanced Diagnostics
Advanced diagnostics involve checking electrical components and water flow systems. Technicians use special tools to test sensors, pumps, and control boards. These tests are beyond simple user checks and need skill. Professionals can locate hidden leaks or damaged parts inside the machine. Calling a technician ensures accurate repair and longer dishwasher life.
