Samsung Dishwasher LC error code

The leak sensor in the base pan detected moisture where it should not be. When this code appears, the dishwasher may turn itself on and keep trying to drain.

Also shown as: LC, LE

Last updated: October 6, 2026

Quick answer: Samsung dishwasher error code LC: leak detected in base pan. The most common cause is water leaking from a hose, pump, or tub seal. Try this first — cut power and look for visible leaks. If that does not clear it, dry the base pan and sensor area.

What causes the LC error?

  • Water leaking from a hose, pump, or tub seal
  • Spilled water reaching the base pan during installation or moving
  • Condensation pooling under the tub
  • Cracked tub or sump
  • Loose hose clamp

How to fix Samsung LC — step by step

Work through these in order, from simplest and safest first. Stop as soon as the code clears.

  1. Cut power and look for visible leaks
    Switch the breaker off, then check under and around the dishwasher for drips - supply hose, drain hose, and door bottom are the usual suspects.
    Safety warning: Unplug or breaker-off before reaching under the machine.
  2. Dry the base pan and sensor area
    If you can access the base, wipe up all standing water and dry the leak sensor. On WaterWall models also check that the water reflector is not blocked, which Samsung notes can trigger LC.
  3. Let it dry for 24 hours
    After mopping up, leave the power off and let the base dry fully for a day. A sensor that stays damp keeps the code active even after the leak stops.
  4. Do not just disconnect the sensor
    Unplugging the leak sensor silences the alarm but leaves the leak. Find and fix the water source instead - a hidden leak rots flooring and cabinets.

When to call a technician

Stop and call a qualified technician if any of these apply:
  • LC returns with no visible spill or recent move
  • You find an active drip from a hose, pump, or seal
  • A hose, pump, or tub part needs replacement
  • Water damage to flooring or cabinets is spreading

Frequently asked questions

Why does the dishwasher turn itself on with LC?

That is by design. When the leak sensor trips, the dishwasher powers up and runs the drain pump to clear water, and it will not turn off until the sensor dries.

We just moved the dishwasher and now see LC. Is it a real leak?

Often not - moving sloshes water into the base pan and trips the sensor. Dry it thoroughly and the code clears.

Can I keep using the dishwasher with LC showing?

No. It will keep trying to drain and will not run a wash cycle. Fix the moisture source first.
