What Does Error LC Mean?

The Samsung dishwasher error LC indicates a water leakage detection issue. This occurs when the internal leak detection sensor detects moisture or water in areas it shouldn't, causing the dishwasher to halt mid-cycle. Common reasons include actual leaks from hoses or fittings, residual moisture in the base, or drainage problems. The error must be addressed before the cycle can resume.

Common Symptoms:

  • Dishwasher halts mid‑cycle and displays "LC"
  • Water or moisture detected under the unit or inside base tray
  • Cycle will not proceed until the code is cleared and moisture issue addressed

Possible Causes

  • Actual water leak inside dishwasher (hoses, fittings, or tub) (high)
  • Residual water or moisture in the base pan triggering the leak sensor (medium)
  • Drainage issues causing water to accumulate in the base (medium)

How to Fix Error LC

DIY Fix Initial Inspection and Reset

  1. Turn off the dishwasher and disconnect power at the plug or circuit breaker.
  2. Check around the base of the dishwasher and floor for visible water or moisture.
  3. Allow the unit to dry, especially the base tray; you may need towels or a wet/dry vacuum.
  4. Reconnect power and run a short test cycle to see if the error returns.

DIY Fix Check Door Seal and Visible Leak Points

  1. Inspect the door gasket for cracks, misalignment, or damage.
  2. Clean the gasket and reseat it if misaligned.
  3. Examine water inlet and drain hoses at the back of the dishwasher for loose connections or obvious leaks.
  4. Tighten hose clamps and correct hose positioning if needed.

Technician Only Internal Component Inspection

  1. Remove the dishwasher’s kick panel and slide out unit if necessary.
  2. Inspect the base tray for water accumulation and thoroughly dry.
  3. Check internal drain pump, hoses, and water inlet connections for leaks or damage.
  4. Test and replace the leak sensor if faulty.

Parts needed: Leak detection sensor, Hoses and clamps, Door gasket/seal

🛑 When to Call a Pro:
  • If water is visibly leaking onto the floor during operation.
