Samsung Washer Error Code Large LED Flash

The Large LED Flash code on a Samsung washer indicates a water leakage fault. The leakage sensor in the machine's base pan has detected moisture, triggering the code and stopping the cycle. Possible causes include loose or damaged hoses, a misaligned drain pump filter cover, a cracked tub, excessive detergent foam, or a faulty sensor itself.

No, you should not continue running the washer when this code is active. The machine has detected water in an area that can damage flooring, cabinetry, and internal electrical components. Stop use and diagnose the source of the leak before running another cycle.

Repair cost depends heavily on the cause. If the fix is as simple as reseating the drain filter cover or reducing detergent, there is no parts cost. Hose replacement is generally inexpensive, typically in the range of $10 to $40 for parts. A cracked tub back or leakage sensor replacement can range from $100 to $350 or more depending on labor rates and part availability.

Several causes of this code are DIY-accessible. Checking the drain pump filter cover for proper seating, inspecting hose connections, clearing debris from the draining bellows, and reducing detergent usage can all be done without specialized tools. If the tub back is cracked or the leakage sensor has failed, those repairs typically require disassembly and are better handled by a technician.

A power reset may temporarily clear the code display, but if the underlying leak condition remains, the code will return as soon as the next wash cycle runs water into the machine. The leakage sensor will re-trigger as long as moisture is present in the base pan or the fault condition persists.
