Daewoo Washer Error Code OF

OF stands for overfill on a Daewoo washer, indicating that water has risen above the safe maximum level inside the tub. This error is triggered when the machine cannot properly regulate water intake. The two most likely causes are a water inlet valve that is not closing completely or a water level sensor that is not accurately detecting the water volume in the tub.

No, you should not continue running the washer when the OF error is active. An overfill condition can lead to water leaking onto the floor, potential damage to the machine's components, or an electrical hazard if water contacts internal wiring. Unplug the washer and turn off the water supply until the fault is diagnosed and repaired.

Repair costs depend on which component has failed. A replacement water inlet valve typically costs between $20 and $65 for the part alone, while a water level pressure switch generally ranges from $15 to $50. If you hire a technician, labor charges will add to these part costs. Diagnosing the exact faulty component before purchasing parts can help avoid unnecessary expense.

The recommended first step is to replace the water inlet valve, as a faulty or weeping valve is the most common cause of this error. If replacing the valve does not resolve the issue, inspect the pressure hose connecting the tub to the water level sensor for kinks or blockages, and test the pressure switch itself for proper function. In rare cases, a failed control board may be responsible and would need to be addressed last.

A reset may temporarily clear the OF error code, but if the underlying cause is not repaired, the error will return as soon as the washer attempts to fill with water again. A faulty inlet valve or pressure switch will continue to cause overfill on every cycle until the defective part is replaced. Resetting without repairing the root cause is not a lasting solution.
