Samsung Dishwasher Error Code LE

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

1. 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.
2. 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.
3. 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.
4. 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.
5. Inspect hoses and clamps: Check the drain hose, inlet hose, and all clamps for leaks, cracks, or loose fittings. Tighten or replace damaged parts.
6. 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.
7. Check the drain pump and filter: Remove debris from the filter and inspect the drain pump area for leaks or broken seals. A faulty pump may need replacement.
8. Test the leak sensor/float: Locate the float or moisture sensor in the base pan. Manually lift the float (if present) to see if it moves freely. If the sensor is corroded or stuck, clean or replace it.
9. Run diagnostic mode: If your model supports service mode, run diagnostics to read stored fault codes and perform sensor tests. This helps isolate the problem to a specific component.
10. Inspect wiring and control board: Look for water-damaged connectors, corroded contacts, or frayed wiring. A shorted board or harness can create false leak readings and may require professional repair.
11. Re-test with an empty cycle: After repairs, run a short rinse cycle empty and watch for leaks and the return of the LE code.
12. Call a professional: If the leak source is unclear, the tub is cracked, or electrical components are involved, contact an authorized Samsung technician to avoid safety risks and further damage.

Maintenance / Prevention Tips

• Inspect door gaskets monthly for signs of wear and replace them when cracked or compressed.
• Check hoses and clamps under the sink and at the dishwasher connection every 6 months.
• Replace rubber inlet and drain hoses every 5–7 years or at the first sign of wear.
• Keep the filter and sump free of food debris to prevent clogs and overflow.
• Ensure the dishwasher is level during installation to avoid improper draining or splashing.
• Avoid overloading the racks which can deflect spray and cause leaks.
• Use the manufacturer-recommended detergents and correct amounts to limit sudsing and overflow.
• Wipe the door edge and gasket dry after heavy use if you notice residual moisture.
• Secure hose connections with quality clamps and check them after service calls.
• Install a high loop or air gap in the drain line per code to prevent siphoning or backflow.
• Keep the area beneath and around the dishwasher dry and visible for early leak detection.
• Run a maintenance cycle with dishwasher cleaner every 1–3 months to reduce buildup.
• Consider installing a flood-safe automatic shutoff valve or flood sensor under the cabinet for peace of mind.
• Schedule professional inspections annually, especially for older units.
• Address small leaks quickly to avoid corrosion and electrical damage that can trigger false fault codes.

FAQs

What exactly does LE mean on my Samsung dishwasher?

LE indicates the dishwasher has detected a leak or moisture in the base pan. The machine usually halts and alerts you so you can inspect and prevent water damage.

Can I keep using the dishwasher after the LE code appears?

No — do not continue running cycles. Turn off power and water, check for visible leaks, and dry the base. Continuing to use the dishwasher risks further water damage and electrical hazards.

How do I reset the LE code?

After fixing the cause and ensuring the base is dry, reset by cutting power for a few minutes (unplug or turn off the breaker) then restoring power. Some models require a specific diagnostic reset; consult your manual.

Could condensation or a spill cause a false LE?

Yes. Condensation, a spill during loading, or lingering water from a prior incident can sometimes trigger the leak sensor. Drying the base and sensor often clears a false alarm.

Is this an expensive repair?

Costs vary: replacing a hose or gasket is relatively inexpensive, while a cracked tub or control board replacement is more costly. Labor and part prices depend on model and local rates.

Conclusion / Safety Notice

Water leaks present both property and electrical risks. If you find visible water, or if the LE code persists after drying and basic checks, stop using the appliance and contact a qualified technician. Do not attempt complex electrical or tub repairs unless you are trained and comfortable; water damage and improper repairs can create safety hazards and void warranties.

If you’re unsure or the problem involves the tub, pump seals, or control board, schedule a professional service call. Prompt, safe action helps protect your home and gets your dishwasher back to reliable operation quickly.
