LE
Leak Error — Base Flood Sensor Triggered
If your Samsung Dishwasher is displaying the error code LE, the control board has detected a fault identified as "Leak Error — Base Flood Sensor Triggered". Understanding the root cause helps you avoid an unnecessary service call.
Owner's Summary
The flood protection sensor under your Samsung dishwasher has activated. There is water in the base of the machine. Unplug it, find the leak, dry the base pan, and fix the source before restarting.
Symptoms
Samsung dishwasher stops immediately, LE shown, water under appliance
Common Causes
- Water leaked into base pan triggering float switch
- Torn or misaligned door gasket
- Cracked or loose pump hose inside machine
- Overfilling from defective inlet valve
How to Fix
- 1 Unplug machine and remove kick plate to inspect base pan
- 2 Locate and dry the base pan — use towels or a wet vacuum
- 3 Identify leak source by running a short cycle while observing internal hoses
- 4 Replace door gasket, pump hose or inlet valve depending on source
Tools You'll Need
Most of these fixes need only basic hand tools. If your repair requires opening electrical housings or testing live components, a multimeter and basic electrical safety knowledge are essential — when in doubt, call a technician.
Technical Explanation
The float switch in the base pan is a normally open switch that closes when water rises above a threshold. The closed switch signal is read by the PCB on a dedicated input pin — when this pin goes LOW, the PCB immediately halts all operations and posts LE regardless of current cycle state.
Is It Safe to Keep Using?
Urgent. Water in the base pan will cause rust, mold, and damage to the motor and PCB if left unaddressed.
Technician's Pro Tip
After drying the base pan and fixing the leak, the float switch must physically return to the open position for LE to clear. If the switch is stuck closed from scale or debris, clean it with a toothbrush — a stuck switch causes persistent LE even after the leak is fixed.
