How To Fix LC Error Code On Samsung Dishwasher?

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.

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.
