Load sensing error - after load sensing operates about 15 seconds, message is displayed during 0.5 second and water level is always fixed to high; water level sensing is inferior.

What LE means on a Daewoo washer

The LE error code on a Daewoo washer indicates a load sensing error. During normal operation, the washer's load sensing system activates to determine the size of the laundry load, which in turn controls how much water is introduced into the drum. When this sensing process runs for approximately 15 seconds without producing a usable result, the LE code is triggered. The error message itself displays briefly for about 0.5 seconds, and as a consequence, the washer defaults its water level to the highest fixed setting regardless of the actual load size.

The root cause is inferior or failed water level sensing. The water level sensing system typically relies on a pressure switch and associated wiring to detect how full the drum is. When this sensing capability is compromised, the load sensing routine cannot complete accurately, causing the control board to time out and lock the water level to high. This wastes water and prevents the machine from operating with correct cycle parameters.

Because the primary diagnostic step points directly to the PCB assembly (the main control board), the failure is most likely located in the control electronics that interpret and process the water level sensor signals. The PCB may be receiving no signal, an out-of-range signal, or corrupted feedback from the pressure sensing circuit. Replacing the PCB assembly is the recommended corrective action when this code appears and persists.

Common causes of LE

  1. 01

    Faulty PCB Assembly

    Part replacement

    The main control board is the primary suspect for the LE code, as it processes water level sensor data during load sensing. A failed or damaged PCB cannot interpret sensor feedback correctly, causing the 15-second timeout.

  2. 02

    Defective Water Level Pressure Switch

    Part replacement

    If the pressure switch that monitors water level has failed or is sending an erratic signal, the load sensing routine receives bad data and cannot complete. This would show up as inconsistent or missing feedback to the control board.

  3. 03

    Damaged or Disconnected Wiring to Pressure Switch

    Wiring / connection

    Broken, corroded, or loose wiring between the pressure switch and the PCB can interrupt the signal path entirely. Visually inspecting the harness connectors for damage or poor seating is a useful first check.

  4. 04

    Blocked or Kinked Pressure Hose

    Wiring / connection

    The small hose connecting the drum air trap to the pressure switch can become blocked with detergent residue or kinked during installation. A blocked hose prevents accurate pressure readings from reaching the switch.

Frequently asked questions about LE

What does LE mean on a Daewoo washer?
LE stands for Load Sensing Error on a Daewoo washer. It means the machine ran its load sensing routine for about 15 seconds and could not get a reliable water level reading. As a result, the washer locks the water level to the highest setting and briefly flashes the code for approximately 0.5 seconds. The fault points to a problem with the water level sensing system or the main control board.
Can I fix the LE error on my Daewoo washer myself?
Some causes, such as a kinked pressure hose or a loose wiring connector, can be checked and corrected without special tools. However, the primary recommended fix is replacing the PCB assembly, which is a more involved repair that requires sourcing the correct control board and basic electronics handling skills. If you are not comfortable working with appliance electronics, a qualified technician should perform the replacement.
Is it safe to keep using my Daewoo washer when the LE code is showing?
Running the washer with an active LE error is not recommended for normal use. The machine will default to the highest water level for every cycle, which wastes water and means load sensing is not functioning correctly. Continuing to run it this way puts extra strain on components and does not address the underlying fault. It is best to diagnose and repair the issue before regular use.
Will resetting my Daewoo washer clear the LE error code?
A power reset may temporarily clear the displayed code, but it will not fix the underlying hardware fault causing the LE error. If the PCB assembly or pressure sensing components are defective, the error will return once the load sensing routine runs again. A proper repair of the faulty component is required for the code to stay cleared.
How much does it cost to repair the LE error on a Daewoo washer?
Repair costs depend on which component has failed. If the fix involves a kinked hose or loose connector, the cost is minimal, mostly labor time. Replacing a pressure switch typically falls in the range of $30 to $80 for the part. A full PCB assembly replacement is the more expensive option, with parts and labor potentially ranging from $150 to $350 or more depending on part availability and local labor rates.
