Samsung Dishwasher Flashing LC Code – WATER LEAK ERROR

Dishwasher shows LC code and needs to be reset. My Samsung dishwasher is flashing the error code LC. During a wash load of dishes the dishwasher stopped and began flashing LC. Now the dishwasher is not usable. I have tried to reset the dishwasher by pressing the buttons on the control panel but it has not cleared the code. I do not see any water leak under the dishwasher. I would like to know what this code means and how do I fix and clear the code? The dishwasher is 8 months old and is model number DW7000.

Samsung Dishwasher Flashing LC CodeHow To Fix Samsung Dishwasher LC Code

Quick answer: The LC flashing on your Samsung dishwasher indicates that the leak sensor in the dishwasher detects a water leak or moisture. To clear the error code LC, simply remove power to the dishwasher for 15 minutes. This should reset the Samsung dishwasher and clear the error code. If the error code does not clear, there may be a LEAK SENSOR FAULT or the dishwasher has an actual WATER LEAK.

NOTE: When the dishwasher bottom pan is damp or has moisture (does NOT have a true water leak) the dishwasher thinks there is a water leak thus causing multiple issues concerning the code LC or LE.

If your dishwasher does not have a water leak, here are other issues that can cause the LC or LE error code…

Dishwasher detergent overfill?

Do not overfill the dishwasher with detergent. If the dishwasher dispenser is overfilled with detergent or has excess detergent, the LC code can occur.

Dishwasher was recently moved or installed?

The dishwasher may have some moisture or water that has gotten on the sensor, give the sensor time to dry to clear the LC code.

Dishwasher recently connected to garbage disposal?

A newly installed garbage disposal that is attached to the dishwasher may be the cause of the problem if the cap on the garbage disposal is not removed. Inspect to be sure the cap is removed to clear the LC code.

Dishwasher keeps flashing LC code?

If the code continues to flash on the display, to clear the error code, remove power by unplugging the dishwasher for 15 minutes. This is to reset the dishwasher and also allow the water or leak sensor to dry out and stop signalling the code. The leak sensor can sometimes get a small amount of moisture on it. When this happens the sensor senses water and displays the error code on the display. (Once the code is displayed, the pump will drain out any existing water but not continue to advance forward.) If removing power to the dishwasher does not clear the error code, you can call for service or follow the information below…

Unplugging the dishwasher and waiting 15 min did not reset the code… If the above solutions do not clear the LC or LE code on your Samsung dishwasher, you can try to adjust the leak sensor within the dishwasher.

    LC error code unit is in rinse mode and i cannot change it..pump works and discharges to garbage disposal properly. small amount of water remains in well below the drain basket. Pump continues to try and pump out remaining water . there are no signs of moisture anywhere else. the check valve works on drain line as unable to blow nitrogen from drain line back to sump.Help!


    Samsung dishwasher dw80k7050ug displays LC error. I recently purchased this home and floor has the dishwasher boxed in so I cannot remove it without ripping up the floor. Is it possible to disconnect the leakage sensor by removing wires from PCB?

  3. I had the same issue. Removed the bottom cover, put blow dryer (NOT HEAT GUN) on high for 2 hrs. No more issue.

  4. Thanks for the help on this one Doug. I may call in a service tech if this happens to me again. I think you’re right about a bad sensor design. I have no signs of leaking underneath my dishwasher (looking through basement) and its has not been moved since installation about 10 months ago. If the code is thrown again, I will make the changes you proposed with 2 washers. My dishwasher opening in my cabinets are JUST tight enough to let it fit but not come out easily.

  5. UPPDATE – Leak Check sensor – Throws a LC code. It will run all night trying to evacuate the remaining water in the system and never shut off. This is clearly dangerous as the components heat up. Of major concern with this is most people will set their machines to wash while they asleep. Any machine that continuously runs as part of the design is a fire hazard. I have to power OFF the machine off at the panel. Samsung put the sensor at the low point in a warpable plastic pan. I understand their logic but the design is faulty.

    It turns out, the LC code goes off even if there is the slightest of humidity on the plastic. (it conducts current too easy and activates the LC sensor – Samsung Part DD94-01062A) A float type valve would be more reliable shutoff for leaks. Also a design feature that limits how long the machine will run with the LC sensor activated is in order.

    The quality control of the LC sensor production is substandard. The probes wobble and are uneven. This causes issues and throws a LC code when there is no water in the pan.

    The only solution I have found is to put two small washers between the LC sensor and the screw attachments. This lifts the sensor up 1/16th of an inch off the plastic pan and is sufficient to stop the LC from throwing the LC code when there is humidity on the bottom plastic panel. It is still low enough to throw a LC code and activate the water removal if there is a real leak.

  6. Thanks for saving us the service call!
    Your mystery moisture may have been caused by a spill on the countertop, like ours was.
    My wife overfilled a pan of water on the edge of the sink.
    The water poured down on the top of the dishwasher door, and must’ve made its way down into the tray and touched the sensor.

    I had the LC code. Did the process of removing the pan and drying it out. When I reinstalled it it still threw the code. I took it apart and found that water had dripped into the cannon plug. I got the hair dryer out and dried everything including the plug to the Leak detector and it worker like a charm.

  8. I had the LC code and was able to fix it using a hair dryer. I turned the hair dryer on high heat and stuck it into the drain at the bottom of the dishwasher (this is to dry up the moisture in the bottom pan). I waited 5-10 min before turning it off and another 5-10 min for the machine to cool down (If you don’t wait for cool down, you’ll get a HC code). I didn’t have to turn off power, empty the dishwasher, or disassemble anything. After cool down I started the wash cycle and it worked!

  9. Had the same error and followed the instructions to clear the drip tray. Working again, thank you!

  10. I had the LC code display on my dishwasher too. Resetting the power for 15 minutes did not work, so I pulled the dishwasher out of the cabinet and used nitrogen to clear the drain lines, which were very much blocked causing water to saturate the leak sensor. Works like a charm!

  11. Hi,
    The Samsung dishwasher DW80K7050US displays the LC error code and it is full of water. What do we do? Thank you, Jolanta
