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:

Condensation from Sanitize or high-heat cycle dripping into base pan (false positive)40%
Door gasket leaking at bottom corners24%
Cracked or loose sump hose connection14%
Leak sensor itself failed or water-logged12%
Tub stress crack near sump10%

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.

Frequently Asked Questions

Why does my Samsung dishwasher show LC with no water on the floor?
Samsung's base pan sensor is more sensitive than most brands. Steam condensation from Sanitize or high-temp cycles can drip off the door seal into the pan and trigger LC without any real leak. Unplug for 30 minutes and let the pan dry. If LC only appears after hot cycles and clears after drying, condensation is the cause.
How do I drain the base pan to clear the LC code?
Unplug the dishwasher, pull it out slightly, and tilt it 45 degrees forward (resting on the door edge) or to one side. Hold this position for 20 minutes so water drains out. Stand upright, wait 10 more minutes, then plug in.
Will the LC code clear on its own?
It will clear once the base pan sensor is completely dry. The unplugged drying method works for condensation. For a real leak, you must fix the source first, drain the pan by tilting, and then the code will clear.
My Samsung keeps getting LC every few weeks. What is wrong?
Recurring LC usually means a slow door gasket drip that collects between uses or a small sump hose seep. Pull the machine out, run a full cycle, and use a flashlight to find the drip point at the door bottom corners or sump area.
