Samsung Dishwasher Error Code LE (Leakage Error)

LE means Samsung’s leak sensor detected water outside the tub, so the dishwasher drains itself and won’t run a normal cycle until the leak is found.

Risk: Moderate

Meaning

LE (sometimes shown as LC) triggers when Samsung’s leak sensor in the base of the dishwasher detects moisture where it shouldn’t be. Once that happens, the dishwasher turns itself on just enough to drain the water away, and it will keep doing that instead of running a normal cycle until the leak source is dealt with. On Waterwall models, the same code can also point to a blocked water reflector rather than an actual leak.

The information provided here is a diagnostic aid and does not replace the intervention of a qualified professional.

Possible causes

No cause is certain until it has been checked on the appliance.

Very likely Worn or misaligned door gasket letting water past during the wash
Likely Regular dish soap used instead of dishwasher detergent, causing suds to overflow the tub
Likely Blocked rotating water reflector, Waterwall models only
Rare Cracked supply line fitting or hose under the unit

Tools needed

Towels
Flashlight
Shallow tray

First checks

Let the dishwasher finish its automatic drain, then unplug it and check underneath for standing water.
Run a finger around the full length of the door gasket for cracks, gaps, or trapped food debris.
Confirm only dishwasher-specific detergent was used, never liquid dish soap or a diluted pod.
On Waterwall models, check the rotating reflector at the bottom of the tub for anything blocking it.

Step-by-step diagnosis

Let the automatic drain finish. Samsung keeps the pump running deliberately, and interrupting it just leaves water where you do not want it.
Unplug the unit and check underneath for standing water. Dry the pan and the sensor.
Open the door and look for foam clinging to the tub walls. If regular dish soap has been used, run two rinse-only cycles with no detergent to clear it before judging anything else.
Run a finger around the whole door gasket, corners included, feeling for a hardened section that no longer springs back.
On Waterwall models, check the rotating reflector along the bottom of the tub. If it cannot travel freely, water sprays where the seal was never meant to hold it.
Restore power. If the code has cleared, run a short cycle and watch the base.

What not to do

Restarting a cycle before finding the leak source. LE tends to come back and can soak the cabinet floor underneath.
Using regular dish soap even once as a substitute. It foams enough to trigger LE and is hard to rinse fully out of the tub.

When to stop

LE returns after the pan is dry, the gasket is sound, and the suds are gone.
You can see water arriving from under the tub rather than past the door.

An error code varies by brand

The same code can have a different meaning depending on the brand and model. Always check your appliance's manual before acting.

When to call a professional

If the simple checks turned up nothing, if the repair involves electricity, gas, or the sealed refrigerant system, or if you have any doubt at all: stop there and hand the appliance over to a qualified technician.
