Daewoo Washer Error Code E3

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.

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.

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.

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.

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.
