Samsung Washer Error Code 1OC

The 1OC code signals an overflow error on the upper washer. It means water has been supplied continuously because the water level detection system is not working properly, so the washer cannot confirm when the correct fill level is reached. The machine stops operation to prevent flooding. The most common starting point is inspecting the hose connected to the water level sensor for kinks, cuts, or damage.

No, you should not continue running the washer with a 1OC error active. The code indicates an uncontrolled water fill condition that can lead to overflow and potential water damage to your home. Stop using the appliance until the root cause is identified and repaired.

Repair costs depend on which component has failed. If the fix is simply repositioning or replacing the water level sensor hose, costs are minimal, typically in the range of a few dollars for the hose itself. A replacement water level sensor generally costs between $15 and $50 for the part, while a water inlet valve can range from $25 to $80. Adding professional labor typically brings the total repair cost to somewhere between $100 and $250 depending on your location and the specific part needed.

Start by locating the hose that connects the water level sensor to the tub and check it carefully for folding, cuts, or disconnected ends. If the hose looks intact, the next steps are testing or replacing the water level sensor and then inspecting the water inlet valve for proper operation. If all those components check out, a control board issue may be the cause.

A reset may temporarily clear the error code, but it will return as soon as the washer attempts to fill again if the underlying problem is not fixed. The water level detection issue must be resolved by repairing or replacing the faulty component. Simply resetting the machine is not a permanent solution.
