Official Meaning

Leak detected – the dishwasher's leak sensor in the base pan has detected the presence of water, indicating a potential leak in the system.

Real-World Causes

  • 1Door gasket is torn, compressed, or not sealing properly
  • 2Internal hose connection has come loose or a hose has cracked
  • 3Wash pump seal is leaking
  • 4Spray arm bearing or feed tube is leaking
  • 5Tub has a crack at a seam or mounting point
  • 6Excessive suds from regular (non-dishwasher) detergent causing overflow

Symptoms

Look for these signs to confirm error LC on your Samsung Dishwasher:

  • LC or LE error code – dishwasher stops immediately
  • Water visible on the floor in front of or beside the dishwasher
  • Dishwasher may beep continuously to alert of the leak
  • The leak sensor light may illuminate on models with indicator lights
  • Error persists even after wiping up visible water (sensor still wet inside)

DIY Fix (Safe)

  1. 1Open the door and check the door gasket for tears, gaps, or food debris preventing a seal
  2. 2Clean the door gasket with a damp cloth – buildup can prevent proper sealing
  3. 3Make sure you are using dishwasher-specific detergent, not dish soap – regular soap creates massive suds and overflow
  4. 4After cleaning up external water, tilt the dishwasher back slightly to help drain water away from the base leak sensor
  5. 5If the leak sensor is simply wet from a one-time overflow, let the dishwasher sit unplugged for 24 hours to dry out

Professional Action Required

  1. 1Remove the dishwasher and inspect the base pan for water – identify the source of the leak
  2. 2Replace the door gasket if it is torn, hardened, or no longer making a watertight seal
  3. 3Inspect all internal hose clamps and connections for leaks – particularly the wash pump connections
  4. 4Check the wash pump shaft seal for dripping – replace the pump if the seal is leaking
  5. 5Inspect the tub seams and spray arm mounts for cracks that allow water to escape
