1. Diagnosing the Issue

Check for Recent Changes

  • Movement: Water might have splashed on the leak sensor if the dishwasher was recently moved.
  • Garbage Disposal Connection: Remove the knockout plug from the garbage disposal to the dishwasher drain hose.
  • Detergent Overload: Excessive detergent can produce extra suds, which the dishwasher might interpret as leaking.

2. Dishwasher is Visibly Leaking:

  1. Run a Cycle for Leak Detection
    Execute a test cycle. The presence of moisture immediately after will help you identify the source.
  2. Inspect the Water Supply Hose
    Check for moisture, damage, loose connections, and gaps in:

    • Hose connection to the dishwasher
    • Hose connection to your home
    • Entire hose length
  3. Level Your Dishwasher
    Ensure the dishwasher is level to prevent potential leaks at the door.
  4. Inspect the Rubber Seal
    Check the rubber seal around the door. Clean it if dirty and adjust if out of alignment.
  5. Check the Tub Sides
    Ensure the tub sides aren’t bowed or stretched. Adjust screws if needed.
  6. Examine Water Nozzles
    Clear any food particles from nozzles and jets to ensure water isn’t being misdirected.

3. Samsung Dishwasher LC Code Displayed:

  1. Disconnect Power
    Safety first! Unplug the dishwasher or switch it off at the circuit breaker.
  2. Check for Visible Leaks
    Inspect the water supply hose, connections, and surrounding areas for signs of moisture.
  3. Let the Dishwasher Dry
    Allow some time for any moisture near the sensors to evaporate.
  4. Inspect for Excess Detergent
    Too much detergent can activate the moisture sensor. Clean any extra detergent and ensure proper usage in the future.

4. Resetting the System

A system glitch can occasionally cause the error code. See a detailed guide to reset the samsung dishwasher.

  • Power Reset: Disconnect the dishwasher from power for 15 minutes, then restart.

Advanced Troubleshooting

1. Inspect for Defective Components

Components like spray arms, water inlet valves, pumps, and sensors might be at fault:

  • Spray Arms: Check for damage or obstructions.
  • Seals and Gaskets: Inspect for wear and tear. Replace if needed.
  • Pumps: Depending on the model, there might be one or two pumps. Test with a multimeter for continuity.
  • Water Inlet Valve: Look for mineral build-up, which might cause overfilling. Replace if clogged.
  • Leak Sensor: Though rare, a faulty sensor might be the culprit. Replacement might resolve the issue.

2. Relocate Leak Sensor

The sensor might be too low in the drip pan if there’s no visible leak. Relocating it higher could solve the issue.
