What's Happening
The leak sensor at the base detected moisture. The dishwasher turns on its drain pump automatically as a safety measure. Common causes include a damaged door gasket, loose hose connections, too much detergent, or condensation buildup. On Waterwall models, a blocked reflector can also trigger this.
How to Fix It
Check the door gasket for tears or debris. Inspect all hose connections underneath for leaks. If you used non-dishwasher soap, run a rinse cycle to clear suds. If no visible leak exists, disconnect power for 24 hours to let the sensor dry out from condensation.
Frequently Asked Questions
What does LC mean on a Samsung dishwasher?
LC means the leak sensor detected moisture in the base pan underneath the dishwasher. The unit activates its drain pump automatically to prevent water damage.
Why won't my Samsung dishwasher turn off when showing LC?
This is normal safety behavior. The drain pump runs continuously until moisture clears. You can disconnect power at the breaker to stop it, then investigate the leak source.
How do I fix the LC error on my Samsung dishwasher?
Check the door gasket and hose connections for leaks. If no leak is visible, unplug for 24 hours to let condensation dry. Also make sure you're using proper dishwasher detergent.
Can too much detergent cause an LC error?
Yes. Excessive suds from too much detergent or regular dish soap can overflow into the base pan and trigger the leak sensor.
