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.
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.

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