How to Fix Samsung Dishwasher LC Leakage Error

Quick Diagnosis

An LC or LE error code on a Samsung dishwasher indicates that the moisture sensor inside the bottom drip tray has detected standing water, signifying a physical leak or an over-sudsing condition.

Step-by-Step Resolution

  1. 1

    Unplug the dishwasher from the electrical wall outlet or switch off its dedicated circuit breaker.

  2. 2

    Pull the dishwasher out from beneath the kitchen counter carcass (take care not to strain water lines).

  3. 3

    Tilt the dishwasher forward gently at a 45-degree angle over a shallow pan or towel to drain any accumulated water from the bottom drip tray.

  4. 4

    Once the water has drained, let the dishwasher sit tilted or open for 24 hours to allow the moisture sensor to dry completely.

  5. 5

    Inspect the drain hose connection under the sink for physical leaks or blockages in the garbage disposal port.

  6. 6

    Check the door gasket seal for tears or food debris that could bypass water to the bottom tray.

  7. 7

    Push the dishwasher back in, plug in the power cord, and run a test cycle.

Alternative Causes & Edge Cases

  • On Samsung linear wash model dishwashers, an LC error can trigger if the optical water level sensor becomes fogged with thick detergent suds, requiring a physical rinse with warm water.
  • On older Samsung rotary washers, the LC code can be triggered by a dislodged drain pump gasket that allows tiny water drops to splash onto the bottom sensor plate.
