A Samsung dishwasher LC (or LE) code means the leak sensor detected moisture—sometimes from a real leak, sometimes from suds or condensation. Here’s how Atlanta South homeowners can respond quickly.
First steps (prevent damage)
Cut power to the dishwasher.
Pull the unit forward slightly, place towels beneath.
Tilt gently (front up a few degrees) to drain the base pan if pooled water is present.
Let the base dry for a few hours; the sensor will often reset once dry if the cause was mild overflow or condensation.
If drainage is also slow, review Dishwasher Not Draining? 6 Reasons and Quick Fixes to rule out clogs that can cause overfills.
Common LC/LE triggers on Samsung
1) Excess suds (wrong detergent or too much rinse aid)
Use dishwasher-only detergent; avoid hand soap.
Reduce rinse-aid setting if you see persistent foam.
2) Misaligned drain hose / standpipe splashback
Secure a high loop under the counter.
Ensure the sink disposer knockout was removed on install.
3) Door gasket weeping
Inspect for nicks, debris, or warping.
Clean the gasket channel; replace if compressed.
4) Inlet valve weep
A slowly leaking inlet valve can drip into the base pan between cycles.
Fix: Valve replacement (pro recommended).
5) Leaky sump or diverter seal
Look for drips under the center of the tub.
Fix: Sump/diverter service kit (model-specific).
6) Float switch / leak sensor stuck
Debris or mineral build-up can fool the sensor.
Fix: Clean/replace the switch or sensor pad.
After drying the base
Run a short cycle and watch:
No LC: You likely had condensation or minor overflow.
LC returns: You have an active leak—book service to prevent floor damage.
