Understanding the LG Dishwasher ‘LE’ Error Code
The LG dishwasher ‘LE’ error code typically indicates a leak or a leak-detection event inside the appliance. When the dishwasher’s flood/float sensor or leak sensor detects water where it shouldn’t be (under the tub or on the base), the machine will often pause or stop operation and display the LE code to prevent further flooding and potential electrical hazards. Causes range from worn door gaskets and cracked tubs to loose hoses, failed seals, or a malfunctioning sensor. User impacts include interrupted wash cycles, standing water inside or under the unit, possible water damage to cabinetry and floors, unpleasant odors from trapped moisture, and a potential safety risk if the leak reaches electrical components. Even when visible water is minimal, an LE event should be treated seriously because prolonged leaks can cause mold growth, structural damage, and greater repair costs.
Common Causes of the LE Error
- Damaged or worn door gasket / tub seal allowing water to escape
- Cracked or corroded tub or sump area
- Loose or split drain hose, inlet hose, or hose clamps
- Failed flood sensor / float switch (false positives or stuck)
- Leaking drain pump or circulation pump seals
- Clogged filter or slow drain causing overflow
- Faulty or shorted control board sending incorrect signals
- Improper installation or dishwasher not level, causing water to pool
- Internal component failure (valves, fittings, or connections)
Troubleshooting Steps for LG Dishwasher LE Code
- Safety first: Turn off power to the dishwasher at the circuit breaker and shut off the water supply before inspecting for leaks.
- Check for visible water: Pull the unit out (if safely possible) and dry any water on the floor, base pan, or under the toe-kick area. Note the location of the water.
- Inspect door gasket and seals for cracks, tears, or debris that prevents a tight seal. Clean and reseat if needed.
- Examine hoses and clamps (drain and inlet) for splits, pinholes, or loose clamps. Tighten or replace as necessary.
- Lift or access the flood/float sensor (depending on model) and ensure it moves freely — a stuck float can cause false LE codes. Test continuity with a multimeter if you can safely access it.
- Inspect the drain and circulation pumps and their seals for signs of leakage. Replace leaking pump seals or pump assembly if necessary.
- Clean filters and remove food debris; a clogged filter can cause overflow and trigger LE. Run a short cycle to test drain performance.
- Reset the dishwasher: turn power off for 5 minutes, then restore power and run a short diagnostic or test cycle to see if the code returns.
- Check for error history or enter the service diagnostic mode (consult your model’s service manual) to confirm the tr
