Samsung Dishwasher LC (1E / LE) Error
What it means
LC stands for 'Leak Check' — a moisture sensor in the base of the dishwasher has detected water or dampness where it shouldn't be, so the machine stops to prevent a leak. Depending on the model the same fault may show as 1E or LE instead of LC; all three mean the same thing. Often it's just trapped moisture or oversudsing tricking the sensor rather than a real leak, but it can also indicate an actual drip from a hose, pump, or door seal.
Common causes of the LC (1E / LE) error
- Leftover moisture or dampness in the base pan triggering the sensor
- Too much detergent creating excess suds that reach the sensor
- Dishwasher not level (front lower than back), letting water pool at the door
- Door gasket pulled out of alignment or debris on the seal
- Garbage-disposal knockout plug left in place, blocking drainage
- An actual leak from a hose, the pump, or a worn seal
How to fix the Samsung Dishwasher LC (1E / LE) error
- 1Power off the dishwasherUnplug it or switch off its breaker for about 15 minutes. A power reset clears the code if the sensor was tripped by a temporary glitch.
- 2Dry out the basePull the dishwasher slightly forward and let it sit with the door open for 12-24 hours so any trapped moisture evaporates. Many LC errors clear on their own once the base is dry.
- 3Reduce detergent and use a rinse aid correctlyUse only the recommended amount of dishwasher detergent. Too much creates suds that the leak sensor reads as moisture.
- 4Level the dishwasher and check the door sealMake sure the unit sits level (the front should not be lower than the back) and inspect the rubber door gasket for misalignment or debris that could let water escape.
- 5Inspect for real leaks and the disposal plugLook under and around the dishwasher for drips from hoses, the pump, or connections, and tighten anything loose. If it drains into a garbage disposal, confirm the disposal's knockout plug was removed during installation.
🧰 When to call a professional
If LC (or 1E/LE) returns after the base is fully dried and you've ruled out detergent and leveling, there's likely a real leak or a failed moisture sensor. Tracing an internal leak or replacing the sensor involves removing panels and accessing the base, so call Samsung Support or a qualified technician.
Samsung LC (1E / LE) error — FAQ
What does the LC code mean on a Samsung dishwasher?
LC means 'Leak Check' — a sensor in the base detected water or moisture and stopped the dishwasher to prevent a leak. On some models the same fault appears as 1E or LE.
Is the 1E or LE code the same as LC?
Yes. 1E and LE are alternate displays of the same leak-detection fault depending on your model and control panel. The causes and fixes are identical.
Can the LC error clear by itself?
Often, yes. If the sensor was tripped by trapped dampness or suds, pulling the dishwasher forward and letting the base dry for 12-24 hours (plus a power reset) frequently clears it with no repair needed.
