Samsung Dishwasher LC Error Code

Samsung dishwashers have a unique feature that any consumer would appreciate: error codes. These simple, helpful codes can help you solve simple problems without the need for professional repair.

An error code on your Samsung dishwasher isn’t fun to deal with, but it can be informative — if you know what the codes mean. By understanding what the different error codes mean, you’ll be able to find and fix any problems that might occur.

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

If the error code keeps appearing, unplug the dishwasher for 15 minutes.

This will clear the error and reset your dishwasher.

However, if this doesn’t work, you should take the following steps:

  1. Unplug the dishwasher for 15 minutes before starting it again.
  2. Check that all connections are secure — especially water connections and hoses.

If resetting your dishwasher doesn’t work, you may require further troubleshooting.

How To Remove Samsung Dishwasher LC Error Code

LC code indicates that there is a leak somewhere in the dishwasher’s water supply system. There may be a faulty leak sensor, or there may be a water leak, but regardless, you should run through a cycle with your dishwasher to check for leaks.

If your Samsung dishwasher has a leak detection code and you have already checked for any external leaks, try to remove the bottom pan from the dishwasher and check it for excess moisture or dampness. If the water trap pan is wet, try to dry it.

To get your dishwasher running at peak performance again, follow the troubleshooting steps below.

Use Correct Type of Detergent

There are two kinds of dish soap: one for the sink and one for the dishwasher. Always use the dishwasher soap because it has a different ratio of detergent that professional chemists design to clean your dishes without creating so many Suds that your dishwasher overflows.

If you’re noticing bubbles when you use your dishwasher, the problem may lie with your detergent. Using too harsh of a detergent can cause cracks or erode the plastic in your dishwasher tub floor.

Put the right soap in the dishwasher, and you’ll avoid common problems like suds blocking the door or leaking out of the door. The best way to stop dishwashing detergent buildup is to switch to a detergent formulated for dishwashers.

Was Your Dishwasher Recently Installed Or Moved?

If you recently moved your Samsung dishwasher to a new location or installed it yourself, moisture may have gotten in the way of the dishwasher’s leak sensor. 

If this happens, Samsung dishwashers will throw an LC error code — but don’t worry; this code is not a sign of an actual leak and can be fixed quickly with a little patience and care. Just wait for the sensor to dry and try again.

Check Garbage Disposal

Garbage disposals that are newly installed and connected to dishwashers can sometimes cause the LC error to happen when the drain cap is not removed.

It’s crucial to remove this before installing, or else the code will remain afterward.

Clogged Drain Hose

If your Samsung dishwasher displays LC Code when there are no other problems with your machine, try operating without any dishes in it. This should clear out any debris or food particles blocking drainage pipes and allow for smoother operation once more dishes are inserted into the unit.

Water may leak during the discharge of dirty water from the dishwasher to the drainage. For this, make sure that the discharge hose and the drainage are not clogged. If water discharge is obstructed, then it should be cleaned from grease and dirt.

Faulty Leak Sensor

If you cannot detect any leakage, the sensor might be faulty. To solve this issue: 

  1. Unplug the dishwasher and disconnect its power source.
  2. Take out the tray at the bottom of the machine and unscrew it.
  3. Disconnect the water leakage sensor and replace it with a new sensor.
  4. Plug the dishwasher back in and make sure that the error no longer exists.

Leaking Door Seals

When the door seal of your dishwasher leaks, water appears under the machine. To confirm the leak, open the dishwasher door and inspect the front seal. If the seal is torn or worn, you can replace it with any commercially available rubber door gasket.

Faulty Water Inlet Valve

If your dishwasher is displaying the Samsung Dishwasher LC error code, it could be because of a faulty inlet valve. Remove the lower panel from your Samsung Dishwasher and check for leaks or damage to the inlet valve tube.
