What LC / LE Means
LC and LE are the leakage error on Samsung’s US dishwasher article: the leak sensor in the base has detected moisture. Samsung adds that when this code occurs the dishwasher will turn itself on and will not turn off while it tries to drain the water away, and that on WaterWall models a blocked reflector can be involved. On a Samsung washer LC is also a leak code, but 1E and LE there mean the water level sensor, so the dishwasher meaning stays here.
Common Causes of LC / LE
- Leak at the door gasket, a hose or the sump
- Overfill or spill reaching the base
- WaterWall reflector blocked, splashing water where it should not go
- Leak sensor failing or condensation on it
🔧 One Safe Check You Can Try
Let the dishwasher finish its self-drain, then switch it off at the breaker and close the supply valve under the sink. Look for water on the floor at the toe-kick and under the sink at the supply and drain connections, and inspect the door gasket for a tear or debris. On a WaterWall model check that the reflector moves freely along its rail. With the base dry and no visible leak, restore power after a few hours and run a short cycle while watching; if LC returns with a dry floor, the sensor or a leak inside the base is the problem, and a technician finds it with the toe-kick and panels off.
⚠ Why You Shouldn't Go Further Than That
- Finding a leak inside the base means the dishwasher out of the cabinet with water and mains wiring in the same space; a slow leak also damages the floor and cabinet the longer it runs.
Opening a panel to inspect or repair something yourself doesn't automatically cancel your manufacturer's warranty — but it can risk accidental damage, and some manufacturers do have specific service conditions. Check your product's warranty terms, or ask us, before deciding.
