The LE error means leak detected — the flood sensor in the base has detected water.
The Samsung washer displays the LE error and halts the current cycle until the underlying problem is fixed.
Check these in order. The first cause accounts for the majority of LE errors.
The rubber door seal (gasket) develops tears, holes, or mold buildup that prevents a watertight seal. Water escapes during the wash phase and collects in the base.
The hoses connecting the water valve to the tub can develop hairline cracks or come loose at the clamp connection, dripping water into the base pan with every cycle.
Cracks in the corrugated drain hose or a loose clamp at the pump connection can allow water to escape during the drain phase rather than the fill phase.
A faulty inlet valve that doesn't close fully allows the tub to overfill — water overflows the tub seal and triggers the flood sensor.
Follow these in order. Stop as soon as the error clears.
The LE error indicates water in an area near electrical components. Unplug before investigating.
Open the door and run your fingers around the entire rubber seal. Look for tears, holes, worn spots, or areas where the gasket has pulled away from the tub. Also check for mold buildup that could compromise the seal.
Pull the machine forward and inspect every hose connection — inlet hoses at the back, the drain hose at the pump, and the internal fill hoses at the tub. Tighten loose clamps or replace cracked hoses.
The flood sensor sits in the base pan. Once water accumulates there, LE will trigger on every start until the pan is dry. Tilt the machine slightly forward to drain any standing water from the base pan.
After drying the base and fixing any visible leaks, run a short wash cycle with the front panel removed so you can see where water is originating during the fill, wash, and drain phases.
