Error Code Explained
What Does the Samsung LC Error Code Mean?
The LC error code on a Samsung dishwasher (also displayed as LE on some models) means the dishwasher's anti-flood sensor — a float switch in the base pan beneath the tub — has detected water. When water accumulates in the base, the float rises and triggers LC, locking out all dishwasher operations until the base is dry and the source of the leak is repaired.
LC is not always a sign of a major leak. Even a small amount of water from a loose hose clamp, a minor door seal leak, or suds overflow can trigger LC. However, the source must always be found and repaired — drying the base without fixing the leak simply results in LC returning on the next cycle.
Root Causes
Common Causes of the Samsung LC Error Code
-
1Door Gasket (Tub Seal) LeakA worn, torn, or deformed door gasket allows water to seep past the door edge during the wash cycle, accumulating in the base pan. This is the most common cause of LC.
-
2Loose Hose Clamp or FittingA hose clamp inside the dishwasher (at the pump, water inlet, or spray arm connection) has loosened, allowing water to drip into the base during operation.
-
3Pump Seal LeakThe circulation pump shaft seal can wear over time, allowing water to pass around the shaft and drip into the base.
-
4Excessive Detergent / SudsSuds overflow from using too much detergent or non-dishwasher soap can flow over the tub walls into the base pan, triggering LC without any actual component failure.
-
5Cracked Tub or HoseA cracked inner tub or cracked wash arm supply hose can cause significant water leakage into the base.
Step-by-Step Guide
How to Troubleshoot the LC Error Code
Safety First: Always disconnect the Dishwasher from power before inspecting any internal components. Do not attempt electrical repairs. If in doubt, call a certified technician.
-
1Tilt the dishwasher to drain the baseTurn off the water supply and unplug the dishwasher. Remove the kick plate at the bottom front. Carefully tilt the dishwasher forward approximately 45° to drain water from the base pan through the front. Set it back level. This deactivates the float switch.
-
2Run a short cycle and observeAfter clearing the base, run a short wash cycle and observe from the front (with the kick plate removed) using a flashlight. Look for drips from the door edge, pump area, or hose connections during the wash phase.
-
3Inspect the door gasketOpen the door and examine the full perimeter of the door gasket. Look for tears, deformation, hardening, or gaps. A gasket that has lost its flexibility cannot form a watertight seal.

When to Call a Samsung Technician
If the leak source is identified as a cracked component, a failed pump seal, or a damaged internal hose, professional repair is recommended. A technician can properly reseal or replace pump components and internal hoses without risk of damaging the dishwasher electronics during disassembly.
FAQ
Frequently Asked Questions — Samsung LC
-
No. LC locks out all dishwasher operation as a flood protection measure. Running the dishwasher with LC active is not possible — and attempting to bypass it risks water damage to the kitchen floor and cabinets.
-
The float switch in the base pan is very sensitive. Even a small amount of condensation or residual water from a one-time event (such as a suds overflow) can trigger LC. Tilt the unit to drain the base, then run a cycle while monitoring. If LC does not return, the trigger was a one-time event.
-
If LC was triggered quickly (after 1-2 cycles), the amount of water in the base is likely small and flooring damage is unlikely. If LC appeared after extended unnoticed leaking (months), check underneath the dishwasher for water damage to the subfloor.
