LG Dishwasher Error Code LE

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

1. Safety first: Turn off power to the dishwasher at the circuit breaker and shut off the water supply before inspecting for leaks.
2. 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.
3. Inspect door gasket and seals for cracks, tears, or debris that prevents a tight seal. Clean and reseat if needed.
4. Examine hoses and clamps (drain and inlet) for splits, pinholes, or loose clamps. Tighten or replace as necessary.
5. 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.
6. Inspect the drain and circulation pumps and their seals for signs of leakage. Replace leaking pump seals or pump assembly if necessary.
7. Clean filters and remove food debris; a clogged filter can cause overflow and trigger LE. Run a short cycle to test drain performance.
8. 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.
9. Check for error history or enter the service diagnostic mode (consult your model’s service manual) to confirm the trigger source of the LE code.
10. If you locate the leak and it is a simple component (hose clamp, gasket), replace or repair it. If the leak source is unclear or internal (cracked tub, faulty control), stop using the machine and call a qualified appliance technician.

Maintenance & Prevention Tips

• Inspect door gasket monthly for cracks or buildup; clean with mild detergent and a soft cloth.
• Clean filters and the dishwasher sump weekly or as recommended to prevent clogs and overflow.
• Check hose connections and clamps at least twice a year for tightness and wear.
• Replace rubber inlet and drain hoses every 5–7 years or sooner if showing wear.
• Run the dishwasher periodically on a hot cycle to reduce buildup and evaporate residual moisture.
• Avoid overloading the racks so water drains freely and does not pool in corners.
• Use the manufacturer-recommended detergents and rinse agents to minimize deposits that can clog drains.
• Level the dishwasher during installation — an unlevel unit can cause pooling and leaks.
• Keep the area under and around the dishwasher dry and periodically check for signs of past leakage (stains, soft wood).
• Inspect the pump seals during routine service visits and replace worn seals promptly.
• If you live in hard-water areas, consider a water softener to reduce mineral buildup on seals and valves.
• Run a maintenance cycle with dishwasher cleaner every few months to remove grease and limescale.
• Install a water-leak detector near the dishwasher to get early alerts before major damage.
• When replacing parts, use OEM or approved replacement components to ensure proper fit and performance.
• Schedule an annual professional inspection if the dishwasher is heavily used or part of a rental/communal property.

Conclusion & Safety Notice

Water leaks are one of the more serious issues a dishwasher can present because they can lead to hidden damage, mold, and electrical risk. Always cut power and water before inspecting the unit. If the leak source is not obvious, if the leak is internal (cracked tub or failed pump seal), or if you’re uncomfortable performing electrical or component tests, stop and call a qualified appliance technician. Continuing to operate a leaking dishwasher risks worsening damage and greater repair cost.

If you are handy and identify a simple external cause (loose clamp, cracked hose, worn gasket), you can often perform the repair safely with the power and water off and basic hand tools. For persistent LE codes, complex component replacement, or any electrical repairs, contact an authorized LG service provider or licensed appliance repair technician.
