Steps:

1. Switch off the dishwasher circuit breaker before opening panels or moving the dishwasher.
2. Most Samsung dishwashers are hardwired and don't have an on/off switch on the appliance.
3. Turn off the dishwasher water supply if you need to move the dishwasher far enough to strain a water line.
4. The LC code means the dishwasher has detected moisture or a leak near the water lines, drain, or bottom pan.
5. WARNING: Water and household wiring can shock you. Don't touch any wires until the breaker is off and you've verified the power is off.
6. Open the sink cabinet and locate the dishwasher drain line.
7. Check the cabinet floor under the sink for water.
8. Make sure the dishwasher drain connection is dry.
9. Clear any clog or old food from the drain line before taking the dishwasher apart.
10. A clogged drain can hold dirty water in the system and trip the LC error.
11. Use a screwdriver to remove the two screws from the lower access plate at the bottom front of the dishwasher.
12. Pull the lower access plate off the dishwasher.
13. Look under the front of the dishwasher for water.
14. Locate the electrical junction box area where the wires enter the dishwasher.
15. WARNING: Keep your hands out of the junction box unless the breaker is off and the wires are verified de-energized.
16. Check whether the electrical cable has enough slack for the dishwasher to slide out.
17. If the cable is too tight, use a screwdriver to remove the junction box cover screw.
18. WARNING: Use a non-contact voltage tester to confirm the wires are de-energized before touching them.
19. Disconnect the three wires inside the junction box and pull the cable free.
20. Mark or photograph the wire connections so they go back in the same positions during reassembly.
21. WARNING: Stop and call a qualified technician if you're not comfortable working with house wiring.
22. Open the dishwasher door and check how the dishwasher is mounted to the cabinet opening.
23. Look for two top mounting clips under the countertop, or side clips screwed into the cabinets or trim.
24. Use a screwdriver to remove the two top screws or the two side screws for your installation.
25. Press the blue tabs on both sides and slide the tray out if it blocks access to the side screws.
26. Keep the screws and clips in a safe spot so they don't get lost.
27. Pull the dishwasher straight out from the cabinet opening.
28. Lift the dishwasher a few centimeters while pulling if a tile or hardwood floor lip catches the front of the unit.
29. Move slowly so the water line, drain line, and electrical cable don't stretch or kink.
30. Use a towel under the feet to avoid scratching the floor.
31. A properly finished floor under the dishwasher lets the unit slide out more easily.
32. Slide the racks or trays out of the dishwasher.
33. Turn the filter from the locked position to the unlocked position and lift it out.
34. Wash the filter until it's free of food and debris.
35. Lift out the screen and wash it as well.
36. Check the drain cavity for an obvious clog.
37. Use a wet/dry vacuum to remove residual water from the drain area.
38. Some water may remain in the drain area even when the dishwasher is working normally.
39. Wear work gloves before handling the underside of the dishwasher.
40. Carefully tip the dishwasher onto its side so you can access the bottom pan.
41. Inspect the underside and the bottom pan for water.
42. The bottom pan holds leak water so it doesn't immediately flood the kitchen.
43. Don't ignore water in the pan, because an active leak can damage hardwood floors or leak into the space below.
44. Use a Phillips screwdriver to remove the screw holding the bottom pan.
45. Store the screw in a safe place.
46. Use a flathead screwdriver to gently pry the small clips holding the bottom pan.
47. Remove the bottom pan from the bottom of the dishwasher.
48. Samsung DW80 and similar models may use one screw and several clips, but other models may differ.
49. Locate the white leak sensor in the bottom pan.
50. Use a microfiber cloth or paper towel to wipe up all water in the pan.
51. Wipe the metal sensor nodes until they are dry.
52. The sensor nodes detect water and put the dishwasher into the LC fault state.
53. Don't relocate or defeat the leak sensor to hide a recurring LC error, because it protects the floor from real leaks.
54. Feel around the main drain at the bottom of the dishwasher for moisture.
55. Follow the drain line toward the exit and check for wet spots.
56. Follow the water intake line by hand and check for wet spots.
57. Check the motor area for moisture.
58. Release the butterfly clip on the main drain only if you need to check inside for old food or a clog.
59. Clear any debris you find, and reinstall the butterfly clip before closing the dishwasher.
60. Align the bottom pan in its original position.
61. Push the pan into the clips until it sits securely.
62. Use a screwdriver to reinstall the bottom pan screw.
63. Use a drill at low speed only if you can avoid stripping the screw or plastic.
64. Carefully stand the dishwasher upright.
65. Slide the dishwasher back into the cabinet opening without scratching the floor.
66. Reconnect any hardwired electrical connections in the same positions as before.
67. WARNING: Reinstall the junction box cover before restoring power.
68. Reinstall the top mounting screws or side mounting screws that secure the dishwasher to the cabinets.
69. Reinstall the lower access plate with its two screws.
70. Turn the dishwasher water supply back on if you shut it off.
71. Check that the drain line, water line, and electrical cable are routed properly and aren't pinched behind the dishwasher.
72. Switch the dishwasher circuit breaker back on.
73. Check the control panel for the LC error.
74. The dishwasher has reset if the LC code clears and the normal preset time appears.
75. Monitor the dishwasher and the under-sink connections for leaks during the next wash.
76. If the LC code returns, moisture is still present, or a leak or clog still needs to be found.
