What it means

This code appears on Samsung dishwashers with a digital display when the leak sensor finds water in the base pan under the machine. The dishwasher stops the cycle and may run the drain pump to keep water off the floor. The same code can mean something else on other brands.

Models covered: Samsung dishwashers with a digital display; codes and their order differ between some series.

Symptoms4

  • LC appears and the cycle stops.
  • Water on the floor in front of the machine or under the cabinet.
  • The drain pump keeps running although the program has stopped.
  • Visible suds at the door or inside the machine.

Possible causes6

  • Hand dishwashing liquid used instead of dishwasher detergent, creating heavy suds that leak from the door.
  • Dirty or damaged door seal, or the machine not level so water escapes at the door.
  • Loose connection on the inlet or drain hose.
  • Leak from internal hoses, the circulation pump or the drain pump.
  • Cracked spray arm or inner tub (less common).
  • Faulty leak sensor or sensor wiring.

How to diagnose6

  1. Turn off the tap under the sink and unplug the dishwasher right away, and dry the floor.
  2. Check the detergent: hand dishwashing liquid alone can cause this code.
  3. Inspect and clean the door seal, and make sure the machine is level and the door closes tightly.
  4. Check the visible inlet and drain hose connections under the sink.
  5. A technician unplugs the machine before removing the lower panel, then traces the leak in the hoses and pumps.
  6. Drying the base pan or tilting the machine may clear the code for a while, but that is only a fix after the technician has found and repaired the water source.

How to fix6

  1. Use only dishwasher detergent, and run a rinse cycle to clear remaining suds.
  2. Clean or replace the door seal and level the machine.
  3. Tighten the external hose connections or replace a damaged hose.
  4. The technician repairs the leaking internal hose or pump, then dries the base pan and sensor.
  5. The technician replaces the leak sensor if it is faulty with no water present.
  6. Run a supervised cycle and confirm there is no water under the machine and the code does not return.

Frequently asked questions

I used regular dish soap. Is that why LC appeared?

Very likely. Hand dishwashing liquid makes heavy suds that leak from the door into the base pan. Dry the floor, clear the suds and run a rinse cycle without detergent.

What should I do first when LC appears?

Turn off the water tap, unplug the machine and dry the floor. Do not restart it until you know where the water came from.

Is tilting the machine to dry the base pan enough?

It may clear the code for a while, but it does not fix a leak. Unless the cause is obvious, like the detergent, have a technician find the water source first.
