Samsung Washer Error Code Medium LED Flash

The Medium LED Flash code on a Samsung washer signals an overflow condition, meaning water has been supplied to the tub continuously without the machine properly detecting the water level. This is typically caused by a faulty water level sensor, a clogged drain hose, or a water supply valve that is stuck open due to debris or freezing. The washer activates this alert to prevent water from overflowing onto the floor.

You should not continue running the washer while this code is active. An overflow condition means water may be filling the tub beyond safe levels, which creates a risk of water damage to your floor, surrounding cabinetry, and the machine itself. Stop the cycle, disconnect power, and diagnose the cause before running another load.

Repair costs depend on what component is at fault. A water level sensor replacement typically runs in the range of $30 to $100 for the part, with additional labor costs if a technician is hired. A water supply valve replacement is generally in a similar price range. Clearing a clogged drain hose yourself costs nothing beyond your time, while a professional service call for diagnosis and repair can add $75 to $200 or more depending on your area.

Start by inspecting the water level sensor and testing it for proper function, replacing it if it is defective. Next, check the drain hose for clogs, kinks, or blockages and clear any obstructions. Also inspect the water supply valve for foreign material or freeze damage that could be holding it open. Addressing whichever of these components is at fault should resolve the overflow condition.

A reset may clear the error code temporarily, but it will not fix the underlying problem. If the water level sensor is degraded, the drain hose is blocked, or the supply valve is stuck open, the overflow condition will return the next time the washer fills. The root cause must be diagnosed and corrected for the error to stay cleared.
