What E1 means on a Daewoo washer

The E1 error code on a Daewoo washer indicates a drain failure. The control board monitors how long the drain cycle takes, and if water is not fully expelled within the allowed time window, the machine halts and displays E1. This error points to a problem somewhere in the drain system, which includes the drain hose, the pump filter, and the drain motor itself.

The most frequent cause of E1 is a physical obstruction or installation problem with the drain hose. If the hose is kinked, crushed, or positioned too high on the standpipe, water cannot exit efficiently. Foreign matter such as lint, coins, or small clothing items can also lodge in the hose or pump filter, restricting flow enough to trigger the timeout. These are the first areas to inspect before assuming a component has failed.

If the hose and filter are clear and correctly installed, the drain motor itself may be defective. The drain pump motor drives the impeller that forces water out of the tub. A motor that is seized, has failed windings, or receives no voltage signal from the control board will prevent drainage entirely. Diagnosing a faulty drain motor typically involves checking for proper voltage supply to the motor during the drain cycle and testing the motor windings for continuity and correct resistance values.

Common causes of E1

  1. 01

    Drain hose improperly installed

    Wiring / connection

    If the drain hose is kinked, too long, or inserted too deeply into the standpipe, the washer cannot push water out fast enough. Check that the hose is routed without sharp bends and is positioned at the correct height for proper drainage.

  2. 02

    Drain hose blocked by foreign matter

    Wiring / connection

    Lint, small garments, coins, or debris can accumulate inside the drain hose or pump filter and restrict water flow. Remove the drain hose and inspect it for obstructions, and clean out the pump filter if accessible.

  3. 03

    Clogged pump filter

    Wiring / connection

    Many Daewoo washers have a pump filter that catches debris before it reaches the drain motor. A heavily clogged filter severely reduces drainage flow and can trigger E1 even when the hose is clear.

  4. 04

    Defective drain motor

    Part replacement

    If the drain pump motor has seized or has failed internal windings, it will not move water regardless of hose condition. This can be confirmed by checking for voltage at the motor during the drain cycle and testing the motor for continuity.

  5. 05

    Control board not signaling the drain motor

    Part replacement

    If the control board fails to send the proper voltage signal to the drain motor, the pump will not activate and E1 will result. This is the least common cause and is typically diagnosed after the motor and hose have been ruled out.

Frequently asked questions about E1

What does E1 mean on a Daewoo washer?
E1 on a Daewoo washer means the machine could not complete draining within the allowed time. The control board monitors the drain cycle, and if water remains in the tub too long, it stops the cycle and displays E1. This points to a problem in the drain system, such as a blocked hose, a clogged filter, or a failed drain motor.
How do I fix the E1 error on my Daewoo washer?
Start by checking the drain hose for kinks, clogs, or incorrect positioning on the standpipe. Remove any foreign matter from the hose and clean the pump filter if your model has one. If the hose and filter are clear, the drain motor may need to be tested for continuity and proper voltage supply, and replaced if it is found to be defective.
Is it safe to keep using my Daewoo washer when it shows E1?
You should not continue running wash cycles while E1 is active. The washer has stopped because it cannot drain properly, meaning water may still be sitting in the tub. Running additional cycles without resolving the drain issue can stress the motor and other components further.
Will resetting my Daewoo washer clear the E1 error?
Unplugging the washer and plugging it back in may temporarily clear the E1 display, but the error will return if the underlying drain problem is not fixed. The code is triggered by an actual drainage failure, so a reset alone does not solve anything. Address the hose, filter, or motor issue first.
How much does it cost to repair a Daewoo washer showing E1?
If the fix is simply clearing a clogged hose or filter, the cost is minimal, typically just your time. If the drain pump motor has failed and needs replacement, parts and labor combined can range from roughly $75 to $200 depending on your location and the cost of the replacement motor.
