What blink means on a Daewoo washer

The blinking display lamp on a Daewoo washer signals a drain failure condition. This error is triggered when the control system detects that the drain cycle has not completed within a 10-minute window. At that point, the program halts and an alarm is activated alongside the blinking lamp. The 10-minute threshold is built into the control logic as a safeguard to prevent the washer from running the drain pump indefinitely when water is not being removed at the expected rate.

The drain system on these machines relies on a pump that receives a voltage signal from the control board to begin operation. If that voltage is not reaching the pump, or if the pump itself has failed, water will not exit the tub and the timer will run out. Foreign matter such as coins, lint, or debris lodged in the pump housing can mechanically block the impeller, preventing water flow even when the pump motor is receiving power. The drain hose route and termination height are also critical factors, since improper installation can create a siphoning issue or a back-pressure condition that slows or prevents drainage.

Diagnosis should begin with a visual inspection of the drain hose for kinks, blockages, or incorrect installation height. Next, the pump housing should be inspected and cleared of any foreign material. Finally, the drain pump output voltage from the control board should be measured to confirm the pump is being commanded to run and is receiving adequate voltage to operate. This three-step sequence helps isolate whether the root cause is mechanical, plumbing-related, or electrical.

Common causes of blink

  1. 01

    Foreign matter blocking pump housing

    Wiring / connection

    Coins, lint, or small items can get past the drum and lodge in the pump housing, jamming the impeller so water cannot be pumped out. Inspect and clear the pump housing access point and look for any debris blocking the impeller.

  2. 02

    Kinked or improperly installed drain hose

    Wiring / connection

    A kinked, crushed, or incorrectly routed drain hose restricts water flow and can prevent the tub from emptying within the 10-minute window. Check that the hose is free of bends and installed at the correct height per the installation requirements.

  3. 03

    Failed drain pump motor

    Part replacement

    If the pump motor has burned out or seized, it will not move water even when the control board sends the correct output voltage. Confirming that proper voltage is present at the pump terminals while the pump fails to run points directly to a failed pump motor.

  4. 04

    No output voltage from control board

    Part replacement

    If the control board is not sending voltage to the drain pump during the drain cycle, the pump cannot activate. Measuring the drain pump output voltage at the pump connector during a drain attempt will confirm whether the board is commanding the pump correctly.

  5. 05

    Blocked or frozen drain hose at standpipe

    Wiring / connection

    A clog at the standpipe connection or a partially blocked household drain can create enough back-pressure to slow drainage beyond the 10-minute limit. Check that the standpipe is clear and that water exits freely when the hose is disconnected and water is poured through it.

Frequently asked questions about blink

What does blink mean on a Daewoo washer?
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.
How do I fix the drain error on my Daewoo washer?
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.
Is it safe to leave my Daewoo washer when it shows the drain error?
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.
How much does it cost to fix a Daewoo washer drain error?
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.
Will resetting my Daewoo washer clear the drain error?
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.
