How To Fix Samsung Dishwasher LC Code Error ?

Dishwashers use error codes to indicate when something is not functioning correctly within the machine. The LC code is a Samsung dishwasher’s most bothersome error code. At times, the dishwasher display may show the Samsung dishwasher LC code even if there is no significant leakage inside the dishwasher. However, there is no need to worry because simple steps can quickly resolve this problem.

What Does The Samsung Dishwasher LC Error Code Mean?

Samsung dishwashers come equipped with a helpful feature that any consumer would appreciate: error codes. These short codes can assist in resolving simple issues without the need for professional repair.

While encountering an error code on your Samsung dishwasher may not be enjoyable, it can provide valuable information if you understand what the codes indicate. By comprehending the meaning of different error codes, you can quickly identify and fix any potential problems that may arise.

When you observe the LC Code flashing on your Samsung dishwasher, it indicates that the machine has detected moisture or a leak inside.

If the error code continues to appear, disconnect the Samsung dishwasher from the power source for 15 minutes. This will clear the error code that appears and reset your dishwasher.

However, if this method fails, you should follow these steps:

  • Disconnect the dishwasher from the power source for 15 minutes before restarting it.
  • Ensure that all connections, especially water, and hoses, are secure.

Overview of Samsung Dishwasher Code “LC”

The error code “LC” indicates that the leak sensor in your dishwasher has detected the presence of water or moisture inside the unit. The reason for the “LC” error code could either be a legitimate water or moisture leak resulting from a damaged water line or connection or it could stem from leftover water or moisture in the bottom pan of the dishwasher. Another possibility is that the leak sensor is malfunctioning and generating the error code.

To troubleshoot the issue, check for any visible leaks in or around your dishwasher and examine the bottom pan for any remaining water. If you find water in the drain pan, the drain hose may be clogged, preventing water from exiting during a wash cycle. This clog is often caused by a buildup of food particles, which can be cleared by removing the filter and cleaning any visible food chunks from it and the drain opening itself.

If you can’t detect any apparent leaks and the drain is not obstructed, there’s an issue with the connection of your water line, or there might be a leak in the water lines themselves. In this case, inspecting the surrounding area for any signs of leaking is essential.

Another possible cause of the “LC” error code is using too much detergent in the dishwasher, as there is a limit to how much detergent the unit can handle. Overfilling it with excess detergent may trigger the sensor and cause the error code to appear.

Lastly, if your dishwasher is connected to a sink or garbage disposal unit, these fixtures may be leaking and causing the dishwasher to pick up moisture. So, inspect them as well for any signs of leakage.

How To Remove Samsung Dishwasher LC Error Code

The LC code indicates that there may be a leak somewhere in the water supply system of the dishwasher. The cause could be a faulty leak sensor or an actual water leak, but either way, it is recommended that you run a cycle with the dishwasher to check for any leaks.

If your Samsung dishwasher has a visible leak detection code and you have already examined it for any external leaks, try removing the bottom pan from the dishwasher and checking for any excess moisture or dampness. If you find the water trap pan wet, attempt to dry it.

Please follow the troubleshooting steps below to restore your dishwasher to optimal performance.

Use the Correct Type of Detergent

There are two types of dish soap available: one for hand washing in the sink and the dishwasher tub floor the other is specifically designed for dishwasher use. It is crucial always to use dishwasher soap because it contains a unique ratio of detergent that professional chemists have formulated to clean your dishes without causing excessive suds that may cause your dishwasher to overflow.

If you observe bubbles forming in your dishwasher, the issue may stem from using the wrong detergent. Using a harsh detergent can cause cracks or erosion in the plastic tub floor of your dishwasher.

By utilizing the correct soap in your dishwasher, you can avoid common issues such as suds blocking the door or leaking out of the door. The most effective way to prevent dishwashing detergent buildup is to switch to a detergent for dishwasher use.

Was Your Dishwasher Recently Installed Or Moved?

If you have relocated or installed your Samsung dishwasher recently, there is a possibility that moisture has interfered with the dishwasher’s leak sensor. In such cases, the dishwasher may show an LC error code.

However, you need not worry; this code does not indicate an actual leak and can be resolved quickly with patience and care. Allow the leak sensor to dry out, and try again.

Check Garbage Disposal

When a newly installed garbage disposal is connected to dishwashers, the LC error code may occur if the garbage disposal cap is not removed. Therefore, removing the garbage disposal cap before installation is essential, or the error code will persist even after installation.

Clogged Drain Hose

If your Samsung dishwasher shows the LC code and there are no other issues with the machine, try running it without any dishes. This should help clear any debris or food particles that may block the drainage pipes and allow for smoother operation when dishes are loaded into the unit again.

Water leakage may occur during the discharge of dirty water from the dishwasher to the drainage system. To prevent this, ensure that the discharge hose and the drainage are not clogged. If the water discharge is obstructed, it should be cleaned from grease or dirt buildup.

Leak Sensors Error

If you cannot detect any leakage, the leak sensor in your dishwasher may be defective. To resolve this issue, follow these steps:

Disconnect the dishwasher from the power source and turn off the power.

Please remove the drip tray at the bottom of the machine and unscrew it.

Disconnect the water leak sensor and substitute it with a new one.

  • Reconnect the dishwasher and verify if the issue has been resolved.

Leaking Door Seals

In case the door seal of your dishwasher is faulty and leaks, you might see water pooling beneath the appliance. To check if the seal is the source of the leakage, open the dishwasher door and examine the front seal. If you notice any signs of tearing or wearing, you can purchase a rubber door gasket from a store and replace the damaged seal.

Faulty Water Inlet Valve

When your Samsung dishwasher displays the LC error code, it could indicate an issue with the inlet valve, which might be malfunctioning. To check for leaks or damage to the inlet valve tube, remove the lower front control panel of the dishwasher.

If any potential sources of leakage or damage to the metal components inside are found, Samsung recommends replacing the part.

Inspect the whole water supply hose and valve for any signs of corrosion or buildup of hard water materials. If any such materials are present, switching off the water supply and replacing the valve should resolve the issue.

Other Error Codes You Can Encounter

Filter clog error

If the filter in Water wall models becomes obstructed and water cannot pass through, an error code 1E (or IE) will be displayed. To resolve this problem, refer to the user manual and clean the small filter at the bottom of the dishwasher. If the error code persists even after you’ve cleaned the filter, please contact our Support Center to schedule a service request.

Incorrect pump operation

If the pump in your dishwasher fails, an error code 3C will appear. To troubleshoot the issue, turn off the water reflector dishwasher and attempt to start the cycle again. If the error code persists, please get in touch with our Support Center for further assistance.

Incorrect supply of hot water

If the water in your dishwasher is too hot, an error code 3E will appear. To resolve this issue, ensure the hot water supply temperature is not above 80 °C (176 °F). If the temperature is within the limit, but the error code continues to appear, please get in touch with our Support Center for further assistance.

Inadequate water supply

If your dishwasher is not receiving water at the required pressure or temperature, you may see an error code 4C or LE error code 4E. To troubleshoot the LE error code, check that the water pressure and temperature meet your water supply requirements. You can refer to the user manual for instructions on how to do this.

Note that Floodsafe hoses are incompatible with Samsung dishwashers and should not be used. Also, make sure that the water supply is turned on. If the error code persists after checking these factors, please get in touch with our Support Center for further assistance.

Drainage error

You may see an error code 5C, SC, 5E, or SE if your dishwasher cannot drain. To resolve this issue, check the drain hose to ensure it is not pinched or kinked, especially if you have recently installed or relocated the dishwasher.

Final Thought

To sum up, there are many reasons why the Samsung Dishwasher may display the LC Error Code, which can affect its performance. It’s essential to address and fix these errors promptly to ensure your dishwasher runs smoothly for an extended period.

You can resolve the issue by resetting your dishwasher. If the problem persists, please comment below, and we can work together to determine the most effective solution.
