Daewoo Washer Error Code blink

A blinking display lamp on a Daewoo washer indicates a drain failure. The machine detected that the drain cycle did not complete within 10 minutes, so it stopped the program and triggered an alarm. The blinking continues until the underlying drainage problem is resolved.

The washer halts the program automatically when the drain error is triggered, so it will not continue operating. However, the tub likely still contains water, which should not be left sitting for an extended period as it can cause odors or mildew inside the drum. Resolve the drain issue or manually drain the machine as soon as possible.

A reset may clear the blinking alarm temporarily and allow you to restart a cycle, but the error will return if the underlying drain problem has not been fixed. The 10-minute timer will trigger the fault again the next time the machine attempts to drain. A reset is only useful as part of testing after you have addressed the root cause such as clearing a clog or replacing a failed component.

Start by checking the drain hose for kinks or blockages and confirm it is installed at the correct height. Then inspect and clean out the pump housing to remove any foreign objects that may be jamming the impeller. If those steps do not resolve the issue, the drain pump output voltage should be checked to determine if the pump or the control board needs to be replaced.

If the fix is simply clearing a blocked pump housing or repositioning a kinked hose, there may be no parts cost at all, just your time. A replacement drain pump, if needed, typically costs in the range of $25 to $80 for the part alone, with additional labor costs if a technician performs the repair. Control board replacement, which is less common, is generally more expensive and can range from $80 to $200 or more depending on availability.
