What Does Error Code LE Mean on a LG Dishwasher?

Leakage detected — flood protection activated.

Water has reached the base pan/flood sensor, so the dishwasher runs the drain pump and stops to prevent floor damage. The water is usually from a damaged door gasket, loose internal hose, or overfill from a sticking inlet valve rather than a bad control board.

Here are the most common causes in order of frequency. Start with the most likely cause before moving to the next:

1

Door gasket leaking or folded 35% of cases
2

Internal hose/clamp loose 30% of cases

How to Fix LG Dishwasher Error Code LE

🔧🔧 Moderate DIY Est. time: 30–60 min

⚡ Safety first: Unplug the appliance before opening any panels or touching internal components.

1

Drain the base pan

Turn power off and carefully tilt the unit forward enough to drain trapped water from the base pan.

⚠️ Disconnect power first and protect the floor with towels.
2

Inspect the door seal

Check the gasket for tears, folds, or debris preventing a tight seal; clean or replace it if damaged.

🔩 LG door seal ($25–$60)
3

Check hoses and clamps

Remove the kick plate and inspect fill, drain, and sump hose connections for drips during a short fill.
4

Test the inlet valve

If the tub overfills, replace a valve that continues feeding water after power is cut or the cycle stops.

🔩 LG dishwasher inlet valve ($35–$90)

How to Reset Error Code LE

After draining the base pan, do not just restart the dishwasher; dry the leak sensor area, fix the visible leak source, then run a short supervised cycle and stop immediately if water appears underneath.

Note: If the error returns after resetting, the underlying issue has not been resolved. Work through the fix steps above.

When to Call a Professional

Call a technician if LE returns but you cannot see a door, hose, or valve leak, because hidden sump seals, tub cracks, or wiring to the flood sensor require disassembly and leak testing under the machine.

Average professional repair cost for this issue: $150–$340

Frequently Asked Questions

Can I keep using my LG Dishwasher when error LE appears? +

It is not advisable. The dishwasher may still power on, but running it while LE is active can worsen the leak fault or damage related parts. Treat it as a soon-as-possible repair.

What most commonly causes LE on a LG Dishwasher? +

Across reported LG dishwasher repairs, the most frequent is door gasket leaking or folded (35% of cases), internal hose/clamp loose (30%), then overfill from stuck inlet valve (20%). Check them in that order before replacing any parts.

LE keeps coming back after a reset — what should I check next? +

A reset only clears the stored LE fault; if it returns, the leak problem is still present. Move on to the physical checks — drain the base pan, then inspect the door seal — since the code will reappear until the root cause is resolved. This is a moderate job — a multimeter and some disassembly are usually involved.

How much does it cost to fix LG Dishwasher error LE? +

A DIY repair typically runs $0–$100 in parts, versus $150–$340 for a professional service call, so handling it yourself saves around $150. Expect the work to take roughly 30–60 minutes.
