One of the most common error codes Samsung dishwasher users encounter is the Samsung Dishwasher LC error. This code signals a leak detection problem, which can be frustrating if not addressed properly. In this article, we’ll break down the top 5 causes of the LC error and guide you on what to do next.
The LC error code is most commonly triggered when the dishwasher detects water in the base pan. Samsung dishwashers come with a built-in leak sensor that activates as soon as moisture is detected in the bottom tray. This could be due to:
An internal leak from a loose or cracked hose
Overflow from too much detergent
A small spill during loading or cleaning
Solution:
Unplug the dishwasher and carefully remove the kick plate to inspect the base pan. If water is present, dry it thoroughly and monitor for recurring leaks. If the issue persists, professional appliance repair service may be required.
Sometimes, the issue isn’t a real leak—it’s the leak sensor itself malfunctioning. If the sensor becomes defective or its connection is loose, it may send false signals to the control board, triggering the LC error even when there’s no moisture.
Solution:
Check the wiring and connection of the leak sensor. If you’re comfortable with DIY repairs, you can test the sensor with a multimeter. Otherwise, contact a qualified technician for diagnosis and replacement.
An improperly installed or unleveled dishwasher can cause water to collect in areas where it shouldn’t, eventually reaching the leak sensor. This is especially common if the dishwasher tilts forward, making it easy for water to seep into the base tray during normal operation.
Solution:
Make sure your dishwasher is level on all sides. Adjust the feet at the bottom if necessary. It’s best to consult your user manual or have a professional check the installation to prevent long-term issues.
A clogged or kinked drain hose can cause water to back up and overflow, leading to leakage. Blockages can also put stress on internal seals and components, making them more susceptible to leaking.
Solution:
Inspect the drain hose for blockages, twists, or damage. Clear any debris and ensure the hose is properly secured and flowing freely. Replacing a damaged hose may be necessary to prevent future leaks.
Using too much detergent or the wrong type of soap (like regular dish soap instead of dishwasher detergent) can cause excessive suds and overflows. This leads to water seeping into the base tray, tripping the leak sensor.
Solution:
Use only the recommended type and amount of detergent for your Samsung dishwasher. If suds or overflow have occurred, unplug the unit and let it dry out completely before restarting.
