Daewoo Washer Error Code E3

Load sensing error

Daewoo codesDaewoo washer codes

Load sensing error: after load sensing operates about 7 seconds, message is displayed for 1 second and water level is always fixed to 'high'. Water level sensing is inferior.

First step from the service manual

Check the water level sensor and the contact part of the connector; change the P.C.B. ASS'Y if necessary.

What E3 means on a Daewoo washer

The E3 error code on a Daewoo washer indicates a load sensing fault. During the load sensing cycle, the machine attempts to detect the weight and size of the laundry load over approximately 7 seconds. If the sensing process fails to produce a valid reading, the error is displayed for 1 second and the washer defaults to the highest water level setting for the remainder of the cycle. This fallback behavior means the machine will continue operating, but it will use maximum water regardless of actual load size, resulting in wasted water and potentially poor wash performance.

The root cause of E3 is inferior or failed water level sensing. The water level sensor (also called a pressure switch or pressure sensor) is responsible for detecting water volume inside the drum. When this sensor cannot accurately report water level data back to the control board, the load sensing routine cannot complete correctly. The sensor communicates with the PCB (printed circuit board assembly) through a connector, and any fault in either the sensor itself or the connector contact points will disrupt this signal path.

Common failure points include a damaged or clogged water level sensor, corroded or loose connector pins between the sensor and the control board, and a defective PCB assembly that cannot properly interpret the sensor signal. Because load sensing relies on detecting subtle changes in water pressure or level, even a partially degraded sensor or intermittent connector contact can trigger this fault consistently.

Common causes of E3

  1. 01

    Faulty water level sensor

    Part replacement

    The water level sensor (pressure switch) may be worn out, clogged with debris, or internally damaged, preventing it from accurately reporting water level data to the control board. Inspect the sensor for physical damage and check that its pressure hose is clear and securely connected.

  2. 02

    Loose or corroded connector contact

    Wiring / connection

    The connector between the water level sensor and the PCB may have loose, corroded, or bent pins that cause an intermittent or absent signal. Unplug the connector, inspect the contacts visually, and reseat it firmly to rule out a contact issue.

  3. 03

    Damaged wiring harness

    Part replacement

    Wiring between the water level sensor and the control board can become pinched, broken, or corroded over time, interrupting the sensor signal. Trace the harness along its route for any visible damage or chafing.

  4. 04

    Defective PCB assembly

    Part replacement

    If the sensor and all wiring and connectors test correctly, the PCB assembly itself may be unable to process the water level sensor input. Replacing the PCB assembly is recommended as a final step after all other components have been ruled out.

Frequently asked questions about E3

What does E3 mean on a Daewoo washer?
E3 on a Daewoo washer indicates a load sensing error. After the machine runs its load sensing routine for about 7 seconds, it cannot get a reliable reading from the water level sensor. The washer responds by displaying the error for 1 second and then locking the water level to the highest setting for the cycle. The fault points to the water level sensor or its connector wiring.
Can I fix the E3 error on my Daewoo washer myself?
In many cases, yes. Start by locating the water level sensor and inspecting the connector that attaches it to the control board. Unplug the connector, check for corrosion or loose pins, and firmly reseat it. If the connector is in good condition and the error persists, the sensor itself or the PCB assembly will likely need to be replaced, which requires ordering the correct parts for your model.
Is it safe to keep using my Daewoo washer when E3 is showing?
The washer will continue to operate after the E3 error, defaulting to the high water level setting. There is no immediate safety hazard, but running every cycle at maximum water level wastes water and energy. It is best to address the underlying sensor or connector fault promptly rather than continuing to use the machine in this degraded state.
Will resetting my Daewoo washer clear the E3 error?
A simple reset may temporarily clear the error display, but it will not resolve the underlying cause. If the water level sensor or its connector is faulty, the E3 code will return the next time the load sensing routine runs. A permanent fix requires inspecting and repairing or replacing the sensor, connector, or PCB assembly as needed.
How much does it cost to repair a Daewoo washer E3 error?
Repair costs depend on which component has failed. If the issue is just a loose connector, the fix may cost nothing beyond your time. A replacement water level sensor typically runs in the range of $15 to $50 for the part alone. If the PCB assembly needs to be replaced, parts costs can range from $80 to $200 or more, and professional labor charges will add to that total.
