Samsung Dishwasher Error Code LC

The LC code means the dishwasher's leak sensor has detected water in the base pan beneath the wash tub. The sensor triggers this code when its voltage reading drops to 3 volts or below for at least 3 seconds. When this happens, the dishwasher shuts off all functions except the drain pump, which runs for about 3 minutes to clear standing water. You should inspect the unit for any visible signs of a water leak before resuming normal operation.

No, you should not continue running the dishwasher while the LC code is active. The code indicates water is leaking into the base of the unit, which can damage flooring, cabinetry, and electrical components. The dishwasher intentionally disables itself as a protective measure, and running it again before identifying and fixing the leak source could cause further damage.

Repair costs vary widely depending on the cause of the leak. A door gasket replacement is typically in the range of $20 to $80 for parts if done yourself, while a water inlet valve can run $40 to $120 in parts. If a technician is needed, labor costs generally add $100 to $200 or more to the total. Sump assembly or tub repairs tend to be on the higher end and may prompt a cost comparison with dishwasher replacement.

Some causes of the LC code are DIY-friendly, such as tightening a loose hose clamp, replacing a door gasket, or correcting detergent usage. However, if the leak originates from the sump assembly, inlet valve, or a cracked tub, those repairs are more involved and may require a technician. Start by visually inspecting the shutter area, door seal, and all accessible hose connections before deciding whether to call for service.

Resetting the dishwasher may temporarily clear the LC code, but the code will return if the underlying leak source has not been repaired. The base pan also needs to be completely dry before the sensor stops detecting a fault. If water remains in the pan, the code will reappear immediately even after a reset.
