An error code on an appliance is most people’s worst nightmare. It signifies that the unit isn’t working correctly, if at all. Samsung’s dishwashers are no different.

From time to time your dishwasher will show different codes to tell you that something is not operating properly.

Today we will discuss what the LC code means and how you can fix it.

What Does the LC Code Mean?

When the LC code is flashing on your Samsung dishwasher it indicates the unit’s leak sensor is detecting moisture or a water leak.

If you’d like to simply clear the code it’s as simple as unplugging the power cord to the dishwater for about 15 minutes.

Doing this should clear the error and reset your dishwasher.

However, if this does not work some additional measures need to be taken.

It could indicate a faulty leak sensor or that your dishwasher does in fact have a water leak.

If you’re lucky, the problem may be that the bottom pan simply has moisture or is damp and it’s tricking your dishwasher into thinking there is a water leak.

If this is the case there isn’t actually a leak and you’ll simply need to dry the bottom pan.

Regardless, let’s discuss some troubleshooting techniques to see what the problem is.

The First Steps to Take

The first thing you should do is check to see if the dishwasher is leaking water.

No in-home service calls. No appointments.

To do so simply pull dishwasher out from counter top and remove metal panel on the right side.

From there you will have some access to the drain pump, in order to see if any visible leaks appears.

If you find some water around the drain pump, it most likely has a leak and the code is being shown correctly.

Other Issues That May Cause the LC Error Code

As we mentioned, there are several other things that may cause your Samsung dishwasher to display the LC error code.

Here are some questions to ask yourself:

Was your dishwasher recently installed or moved?

If you recently had your Samsung dishwasher installed or moved, water or moisture may have gotten on the leak sensor.

If so, just allow the sensor time to dry and then try clearing the code again.

Did you overfill the dishwasher with detergent?

Overfilling the detergent dispenser on your Samsung dishwasher is a bad idea.

When you overfill the dispenser, the machine may detect excess detergent and can begin showing the LC code.

Did a garbage disposal recently get connected to the dishwasher?

Garbage disposals that are newly installed and connected to dishwashers can actually cause the LC error.

This happens when the cap is not removed from the garbage disposal. If this is the case simply remove the cap and clear the code.

If none of these issues pertain to you, keep reading.

The LC Code is Still Flashing, Now What?

So, you’ve tried unplugging the machine for 15 minutes and it’s still flashing?

Your next step is to call a professional for service or simply follow the steps below.

Disconnect Power

Before going any further you’ll need to disconnect all power.

So, you’ll want to unplug your Samsung dishwasher from the wall and turn the breaker off to it.

Remove Dishwasher from Under the Counter

If you look under the counter you’ll see small clips that are fastened with a couple screws that hold the dishwasher in place.

Simply remove the screws and slide the machine out from under the cabinets to gain access to the bottom of it.

Once you have the unit out you’ll need to turn the dishwasher on its side to provide the access you need.

Remove Bottom Panel

The entire bottom of the Samsung dishwasher is covered by a panel or tray.

This part is made to keep leaking water from reaching the floor beneath.

You may notice that there is a bowl shape in the middle of the bottom tray. This is where the sensor is located.

When water collects it tells the sensor there’s water build-up and the machine gets stuck in a cycle where it constantly tries to drain the water.

Dry Water or Moisture Inside the Dishwasher

Dry the sensor and bottom dishwasher pan with a rag. Make sure you get as much of the moisture or water as you can.

Locate the Leak Sensor

The leak sensor should be located on the bottom of the unit or in the drain pan.

Once you find it, relocate it a few inches higher.

This will prevent the code from coming back if your problem is just a little moisture.

While you still have the machine open it’s a good idea to check hoses and water lines for visible signs of leakage.

If you find a leak this must be repaired or the LC code will keep coming back.

Put the Dishwasher Back in Place

Replace and secure the bottom panel on the machine. Slide it back under the counter and replace the screws to re-secure it in place.

Turn the Power Back On

Now you can plug the machine back in and turn the breaker on.

Test the Machine

Now the moment of truth. Run a test cycle to see if the LC code is cleared and the Samsung dishwasher is working properly again.

The steps discussed above are usually the only fix required to clear the LC code and allow you to continue on with using your Samsung dishwasher.

If you still need help or can’t get the code to clear you can also try to call Samsung’s dishwasher support line.

They will need to know your model number and a brief description of what’s going on.

  1. Seeing a lot of models that leaked December 2021 – January 2022…. Mine was one of these. Fixed it twice but now it needs a $150 seal. Replacement after only 2 years.

  2. VERY helpful. Tightened up my leaking connection, but LC code on Samsung Dishwasher continued, even after being off for 15 minutes. (Disconnected). Was able to pop the drip tray down from front of washer, mop up collected water from the leak, snap tray back in place and…..worked perfectly. Thank you.

  3. I had the same LC error. I found the water inlet valve on the bottom of the unit had worked itself slightly loose. After drying out the bottom tray and tightening up the connection, it worked great. I’m glad I found this post thanks for all of the contributions, it really helped.

  4. I found this MOST HELPFUL. We bought a new Samsung DW, and first run out after install it had this error DL code. I followed the instructions here and found some water in the tray. I emptied it all out and once I stood the unit back up, I noticed my contractor had not paid any attention to inside the unit… there is a rectangular steel mesh screen inside unit at bottom, held in by a round plastic piece. Both had not been attached – they were loose, so water went the wrong way when we ran the unit. I dried everything out, properly attached these two pieces inside the unit and IT RUNS!!! No DL code. Thank you.

  5. Followed your procedure which is excellent. Two things I found were 2 plug Jets on the spray nozzles. too much water at the door. And a dead roach that had crawled in the bottom pan and shorted the leak sensor! Contact me and I’ll send you a picture.

  6. Purchased in 2019, no issues till dec. 2021. Lc code, water leak.
    Read the blogs and tried a few things. 1st had to dry out washer just to get code to clear. Looked like to much water was in it and leaking at bottom of door. Replaced the waterfill inlet switch. $15.00. Still not it. Read about a possible crack in the bottom spray arm. It throws water at the door. Bingo that was it. Had a small crack, did thick layer of super glue and clamped. Ran washer and no leak at the door. About $50 to replace. We will watch the repair I did and see.
