Samsung Dishwasher LC / LE Error: Leak Sensor Fix & Part (#DD81-02132A)
Quick Answer: The LC (or LE on older models) blinking error code on a Samsung dishwasher means the moisture sensor in the bottom drip tray detected water or condensation. Unlike Bosch, Samsung uses an electronic two-prong moisture sensor (#DD81-02132A) that frequently triggers false LC alarms even when only 2 drops of moisture touch it.
⚠️ Why Samsung LC Keep Coming Back With a Dry Pan: Samsung's leak sensor doesn't use a mechanical float—it uses two exposed metal pins that detect electrical conductivity! Once soapy water touches that sensor, dried soap residue left between the pins conducts electricity from humid air and triggers false LC codes forever until wiped with rubbing alcohol or replaced.

Step 1: Free 2-Minute Reset & Test (Try This First)
Before ordering replacement parts, perform this quick reset sequence to rule out a temporary sensor trip:
- Turn off the circuit breaker to the Samsung dishwasher (you cannot turn it off with the power button while LC is blinking).
- Pull the dishwasher out, remove the bottom cover pan, and wipe the tray completely dry.
- Clean the two metal prongs of the plastic moisture sensor on the bottom tray with rubbing alcohol to remove conductive soap film, or dry it with a hairdryer for 5 minutes.
- Turn the breaker back on. If water actively drips from the left side wall, replace the Case Brake Water Inlet Assembly (#DD82-01111A).

Frequently Asked Questions (Samsung LC / LE)
Why won't my Samsung dishwasher turn off when LC is flashing?
When LC is active, Samsung locks out the front touch panel and runs the drain pump for safety. You must flip the kitchen circuit breaker off or unplug the unit under the sink to silence it.
