Understanding the Samsung “LE” Error on Dishwashers
The Samsung “LE” error code on a dishwasher stands for a leak or leakage detection. It appears when the appliance’s internal leak sensor (often a float or moisture sensor inside the base pan) senses water where it shouldn’t be. This condition can be caused by a real plumbing leak or a false trigger from residual moisture, condensation, or a failed sensor. User-facing impacts include interrupted wash cycles, puddles on the kitchen floor, potential water damage to cabinetry, longer drying or completion times as the unit may halt mid-cycle, and — in worst cases — electrical hazards if water contacts wiring. Addressing an LE fault promptly reduces the risk of structural damage and safety issues.
Common causes
- Damaged or worn door gasket (seal) allowing water to escape the tub.
- Cracked tub or loose fittings causing slow leaks.
- Loose, kinked, or damaged drain or supply hoses.
- Faulty drain pump or leaking pump seals.
- Malfunctioning float/LE sensor or moisture probe in the base pan.
- Clogged filter or drain leading to overflow.
- Loose hose clamps or improperly secured connections.
- Incorrect installation (not level) causing splashing or overflow.
- Faulty control board or wiring short producing a false alarm.
- Residual water left in the base from a previous leak or condensation buildup.
Troubleshooting steps
- Stop and power down: Immediately stop the cycle, turn off the dishwasher, and switch power off at the breaker or unplug it. Turn off the water supply to prevent further leakage.
- Check for visible water: Remove the kickplate or base access panel (if accessible) and inspect the base pan for standing water. Use towels or a small wet/dry vacuum to remove any water.
- Dry the base and sensor area: Thoroughly dry the sump/base area and the float or moisture sensor. Sometimes a false LE is caused by residual moisture; drying may clear the code.
- Reset the dishwasher: With the unit dry, restore power and run a reset: unplug or flip the breaker for 1–5 minutes, then power back on. Some Samsung models require a specific diagnostic reset — consult the manual.
- Inspect hoses and clamps: Check the drain hose, inlet hose, and all clamps for leaks, cracks, or loose fittings. Tighten or replace damaged parts.
- Examine door seal and tub: Inspect the door gasket for cracks or deformities and the tub for visible cracks or corrosion. Replace a compromised gasket or tub component.
- Check the drain pump and filter: Remove debris from the filter and inspect t
