Samsung Dishwasher Error Code LE (Leakage)

The LE code indicates that the leakage sensor in the base pan of the dishwasher has detected a voltage at or below 4.5V for at least one second, which signals the presence of water in the base. The dishwasher shuts down automatically when this occurs to protect against water damage. The leak can originate from hose connections, the sump and tub assembly, or the drain pump assembly. In some cases, a faulty main control board can also trigger this code without an actual leak present.

No, you should not run the dishwasher while the LE error is active. The code indicates water is escaping from the wash system and pooling in the base of the machine, which creates a risk of water damage to surrounding cabinetry and flooring. There is also a potential electrical hazard if water contacts wiring or components in the base. Keep the dishwasher off until the leak source is identified and repaired.

Repair costs vary depending on the root cause. Replacing a drain pump or hose assembly typically runs in the range of $100 to $250 including parts and labor. A sump and tub assembly replacement can cost $150 to $350 or more depending on parts availability. If the main control board is the source of the fault, board replacement costs generally fall between $150 and $400 with labor. Getting a diagnostic visit from a technician before ordering parts helps avoid unnecessary expenses.

Some causes of the LE error, such as a loose hose clamp, are accessible to a confident DIYer who is comfortable removing the lower access panel and inspecting the base compartment. However, replacing components like the sump assembly, drain pump, or main control board typically requires disassembling significant portions of the dishwasher and is best handled by a technician. Always disconnect power to the unit before inspecting internal components. If water is present in the base pan, allow it to dry completely before attempting to identify the leak source.

Resetting the dishwasher may temporarily clear the LE code, but the error will return as soon as the leakage sensor detects low voltage again during the next cycle. The underlying cause, whether a physical leak or a faulty sensor or board, must be corrected for the code to stay clear. Repeatedly running the machine after a reset without fixing the leak can result in progressive water damage.
