Samsung Washer Error Code OC

The OC code on a Samsung washer signals an overflow error, meaning the machine detected water rising above the safe level inside the drum. This is most often caused by a malfunctioning water level sensor, a damaged or blocked sensor hose, a stuck water supply valve, or a clogged drain hose. The washer stops the cycle automatically to prevent water from spilling out. Inspecting the water level sensor and its connected hose is the recommended first step.

You should not continue running the washer while the OC error is active. The code indicates the machine has detected an overflow condition, and continuing to operate it could result in water spilling onto the floor and causing water damage. Stop the cycle, unplug the unit, and diagnose the cause before running another load.

A reset may temporarily clear the OC code from the display, but it will not fix the underlying problem. If the water level sensor, its hose, the supply valve, or the drain hose is faulty, the error will return as soon as the machine attempts to fill again. Addressing the root cause is necessary before the washer will operate normally and reliably.

Some causes of the OC error are DIY-friendly. You can inspect the water level sensor hose for kinks, cuts, or freezing, and clear a clogged drain hose without special tools. If the hose is frozen, applying a hair dryer on low heat is a straightforward fix. However, if the water level sensor itself has failed or the water supply valve is faulty, replacing those components requires more comfort with appliance repair work.

The repair cost depends on the root cause. If the issue is a kinked or frozen hose, there may be no parts cost at all. A replacement water level sensor typically runs in the range of $15 to $50 for the part. A water supply valve replacement can range from $20 to $75 for parts. Adding professional labor will increase the total cost depending on your local service rates.
