At some point, you may see the leak sensor error code "LC" show up on your Samsung dishwasher. More often than not, this sign will appear while the dishwasher is at the start of a cycle, though it can appear at the end of the cycle as well. But what if you check the dishwasher and there is no leak. What do you do? We have researched why this may occur, and in this post, we will go over it.
There are a few reasons you may get a leak sensor error code on your Samsung dishwasher, even when there is no leak. This error code can also occur when there is a moisture issue, not a necessary leak within the dishwasher.
It can also be triggered when there is an issue with the amount of detergent in the dishwasher or a garbage disposal problem.
Note that you will not be able to operate the dishwasher until you resolve the error code. Even resetting the dishwasher typically won't clear that the issue either. Continue reading to learn more about how to troubleshoot this error code.
What is the meaning of LC in Samsung dishwasher?
The error code "LC" indicates that the Samsung unit has detected a water leak or excess moisture somewhere inside of the dishwasher. It's unlikely that you'll be able to clear this specific area code by resetting the dishwasher. That being stated, it's best to use your user's manual to learn how to troubleshoot it.
In some cases, when the error code pops up and there is no leak, it could be the result of a faulty sensor. But if it's not, you'll need to explore other potential culprits. Let's take a look at a few common ones.
The pan needs to be drained
Sometimes you may not have a leak issue necessarily, but the drain pan will need to be emptied. This usually happens if water previously leaked and is no longer leaking. In this case, the drain pan will still need to be checked as the sensor will detect the water at the bottom of the pan.
To drain the pan, pull it out of its position, pour out any remaining water, and then dry the pan with a dry cloth. After you replace the pan, take a look at the dishwasher drain pump to see if there are any areas of leaking water around it. Sometimes, the drain pump will be the source of the leak due to a malfunction.
Excessive moisture due to recent installation
If the dishwasher has recently been installed or you've moved it for some reason, this could be the issue as well. Sometimes, during new installations or moves, moisture can get inside the dishwasher's bottom, which will trigger the leak sensor. To see if this is the case, open up the dishwasher and check for any visible moisture at the bottom of the tub.
If the bottom of the tub feels damp, dry it off with the cloth. If it doesn't turn off, let the door hang open for about an hour or two to dry out the unit altogether. Afterward, try clearing the code with a reset to see if that fixes the issue.
The detergent is overfilled
Sometimes the detergent will be filled up past the fill line, causing the leak sensor to go off. If you use liquid detergent instead of powered detergent, this is more likely to happen. Check the dispenser to see if it is past the fill line. And if it is, remove some of the detergent and try to clear the error code afterward.
The garbage disposal was recently installed
Most dishwashers are connected to the garbage disposal via a drain pump. If the garbage disposal was recently installed, it could cause the area code to appear on the dishwasher.
This typically happens when the disposal cap is not removed. Clear the code, remove the cap, and reset the dishwasher.
If the error code continues to flash, try taking the following steps to clear it.
Steps To Clear LC Error Code on Samsung Dishwashers
1. Remove the power cord
Try performing a manual reset by removing the power cord from the electrical socket. Let the cord remain unplugged for about 10 or 15 seconds to clear the dishwasher's control panel.
You can also turn off the unit at the circuit breaker by simply flipping the switch to the off position and then flipping it back on after about 4 to 5 seconds.
2. Pull the dishwasher out from the counter
Next, remove the dishwasher from its position. You may need a screwdriver to do this. If your dishwasher has small clips attached to the bottom of the countertop, press them down firmly and lower the dishwasher to the floor.
If your dishwasher is attached using an adhesive, removing it won't be possible. In this case, it's best to reach out to a technician. After you slide the dishwasher out from beneath the cabinets, open up the control panel and take a look at the bottom of a dishwasher.
3. Dry out the drain pan
Take a look at the water tray at the bottom of the dishwasher (which is located next to the sensor). Double-check that it to ensure it's free of water and moisture. If it contains any water, pour it out and then dry it off with a dry cloth.
4. Locate the sensor
Next, locate the leak sensor, which is right next to the pan. Unscrew the sensor using a screwdriver and move it about three to four inches above the drain pan. This will prevent the error code from being triggered easily (if it's triggered by moisture and not an actual leak).
While you have access to the drainage area, look at the water lines and drain hose to ensure that they're both leak-free.
5. Replace the dishwasher panel
Place the dishwasher panel back on and screw it back in place. Next, slide the dishwasher back into its position beneath the counter.
6. Turn the unit back on
Next, plug the unit back in and turn it back on. The manual reset should have reset the code, and you should no longer see the error code.
Next, run a test cycle to ensure that the code has completely cleared. If it has, use the dishwasher as usual. If it doesn't clear, reach out to a technician for assistance.
How do you reset the leak sensor on a Samsung dishwasher?
Yes. To do so, you'll need to reset the sensor with a hard or a manual reset. To do this, unplug the unit at the power cord or reset it at the circuit breaker.
Leave it unplugged for about 10 to 15 minutes before plugging it back in. This will allow the unit to reset the sensor and the control board at the same time.
How do I run a diagnostic on my Samsung dishwasher?
Here are the steps to run a diagnostic on most Samsung dishwasher models (note that this may vary slightly per model):
Press the "Auto," "Delete," and "Power" buttons simultaneously and hold them down for 2 seconds to enter the diagnostic mode. If you want to advance to the next step in the mode, press the "Normal" button on the control panel. Make sure that the door is closed before attempting to enter the diagnostic mode.
How long is a Samsung dishwasher warranty?
Samsung dishwashers have a warranty period of one year from the date of purchase. The warranty covers any part that fails due to bad workmanship or component failure. Samsung will also provide free labor and on-site servicing if the issue is related to a flaw in the dishwasher materials.
The warranty only applies to dishwashers used within the United States that are used for non-commercial reasons. It doesn't cover typical wear-and-tear or any damage resulting from a bad dishwasher installation.
