Samsung Dishwasher LC Error Code: Leak Sensor Triggered
Quick Answer
The Samsung LC error code means the leak sensor in the base pan detected moisture. Samsung's base pan sensor is more sensitive than most competitors and frequently triggers from condensation after hot cycles, not a real leak. Before tilting the machine, unplug for 30 minutes to let condensation dry.
The Samsung LC error code means the leak sensor in the base pan detected moisture. Samsung's base pan sensor is more sensitive than most competitors and frequently triggers from condensation after hot cycles, not a real leak. Before tilting the machine, unplug for 30 minutes to let condensation dry. If LC returns immediately at startup with no cycle run, a real leak is present. To fully clear LC, unplug, tilt the unit 45 degrees forward to drain the base pan, wait 20 minutes, stand upright, then plug back in.
What Does the LC Code Mean?
LC fires when water reaches the drip tray at the bottom of the dishwasher. Samsung's sensor is unusually sensitive - condensation from a Sanitize or steam cycle can drip off the door seal and collect in the pan, triggering LC with no actual leak. A true leak feels wet under the machine and returns immediately after clearing.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Symptoms You May Notice
- LC code displayed, cycle stops or will not start
- Machine was running a Sanitize or high-temp cycle before the code appeared
- No visible water on floor under dishwasher
- Code clears after drying period but returns after next hot cycle
- Wet base pan when unit is pulled out and tilted
Can you reset a Samsung dishwasher to clear the LC code?
LC will NOT clear by holding Start/Cancel alone if water remains in the base pan. Procedure: (1) Unplug. (2) Tilt 45 degrees forward to drain the pan. (3) Wait 20 minutes upright. (4) Plug in. The sensor will reset automatically when the pan is dry. If the code returns within the next 2 cycles, a real leak source must be repaired.
