What Is Samsung Dishwasher Error Code LC?
LC stands for Leak Check. This error appears when the dishwasher detects water leakage or moisture in the base pan. To prevent flooding, the dishwasher stops immediately and may continuously drain.
This safety feature is built into dishwashers from Samsung Electronics and is commonly triggered by actual leaks or excess moisture.
Fast Diagnosis Checklist (Start Here)
Go through each item carefully:
☐ Water leaked under the dishwasher
☐ Excess foam or detergent overflow
☐ Loose or damaged hose connections
☐ Dishwasher tilted or not level
☐ Condensation or spill triggered sensor
☐ Faulty leak sensor / float switch
🛠️ Fixes You Can Try at Home
1) Power Reset & Dry the Base
Turn off the dishwasher.
Unplug it or switch off the circuit breaker.
Pull the dishwasher slightly forward.
Let it sit 12–24 hours to allow moisture to dry.
Many LC errors clear once trapped water evaporates.
2) Check for Visible Leaks
Inspect the area under and around the dishwasher.
Look for dripping from hoses, pump, or door seal.
Tighten any loose connections.
Even a small drip can trigger the LC error.
3) Inspect Door Gasket and Seals
Open the door and examine the rubber gasket.
Clean it with a damp cloth.
Replace it if cracked or worn.
A leaking door seal is a common cause.
4) Reduce or Change Detergent
Use HE dishwasher detergent only.
Do not overfill detergent compartments.
Avoid mixing detergents.
Excess foam can overflow into the base pan and activate the leak sensor.
5) Level the Dishwasher
Ensure the dishwasher is level front-to-back and side-to-side.
Adjust the leveling feet if needed.
An unbalanced dishwasher can cause water to spill internally.
When DIY Fixes Don’t Work
If the LC error returns immediately after drying and inspection, the issue may involve:
Cracked internal hose
Leaking circulation or drain pump
Faulty leak sensor
Control board misreading moisture
Professional service is recommended in these cases.
