Samsung Washer Error Code Overflow error

The overflow error on a Samsung washer means the machine has detected that water inside the drum rose above the safe maximum level, and this condition was detected three separate times in a row. The washer uses a pressure sensor to monitor water levels and triggers this error when that threshold is repeatedly exceeded. It is most often caused by a water inlet valve that is not closing properly or a pressure sensor that is giving inaccurate readings. Addressing this promptly is important to prevent water from spilling into the machine cabinet or onto the floor.

It is not recommended to continue running the washer while this error is active. An overflow condition means the machine is allowing or detecting more water than intended, which can lead to water leaking inside the cabinet, damage to electronic components, or flooding on the floor. Power off the washer until the cause is identified and corrected.

Repair costs depend on which component is at fault. A replacement water inlet valve typically costs between 25 and 75 dollars for the part, while a pressure sensor is generally in the 15 to 50 dollar range. If you hire a technician, labor charges can add 80 to 150 dollars or more depending on your location and the complexity of the repair. A control board replacement, if needed, is significantly more expensive and may factor into a repair versus replace decision.

Some steps are DIY-friendly, such as restarting the machine, inspecting the pressure sensor hose for kinks or blockages, and confirming the washer is not filling with water while powered off. If those checks do not resolve the issue, replacing the water inlet valve or pressure sensor involves working with water supply connections and internal components, which requires moderate appliance repair experience. If you are not comfortable with those repairs, a certified technician should handle them.

Turning off the power and restarting the washer is the first recommended diagnostic step and may clear the error if the overflow condition was a one-time anomaly. However, because this error requires three consecutive overflow detections to trigger, a simple reset is unlikely to permanently resolve a hardware fault such as a failing inlet valve or defective pressure sensor. If the error returns after a reset, further diagnosis is needed.
