The LC error on your Samsung Washer means the machine has detected a possible leak inside the cabinet or base. The washer stops the cycle and drains water as a safety precaution, so check for standing water and loose hose connections before restarting.

Error code LC
Meaning Leak detected — water sensor in the base has picked up moisture where it shouldn’t be
Severity Medium — the washer won’t run a full cycle until the leak source is fixed
Time to fix 15–45 minutes
Tools needed Towels, flashlight, adjustable pliers

What the LC error means

Samsung washers with a leak-detection sensor in the base pan will trigger the LC code when water pools where the sensor sits. This is a built-in safety feature meant to stop a small leak from becoming a bigger problem, similar in purpose to how the Samsung Washer SE Error Code: Causes and Fixes protects against sensor faults. The washer will pause, drain, and display LC until it no longer detects moisture.

In most cases the leak is small and comes from a loose connection rather than a cracked tub, but it’s worth investigating right away since ignoring it can lead to water damage on your floor.

Common causes

  • Loose or worn drain hose connection at the back of the washer
  • Water supply hoses not fully tightened at the wall or washer inlet
  • Detergent drawer or dispenser overflowing and dripping down into the base
  • Door boot seal (on front-loaders) cracked or not sealing properly
  • Condensation buildup mistaken for a leak by the sensor
  • Damaged internal water line or pump seal

How to fix the LC error

  1. Unplug the washer and check the base: Tilt or pull the washer out carefully and look for pooled water in or under the cabinet.
  2. Inspect hose connections: Tighten the drain hose clamp and both hot/cold water inlet hoses at the wall and washer.
  3. Check the door seal and dispenser: Wipe down the door boot for tears and make sure detergent isn’t overflowing the drawer.
  4. Dry the base thoroughly: Use towels to soak up any moisture around the leak sensor before restarting.
  5. Run a test cycle: Plug the washer back in and run a short rinse cycle while watching for new leaks.
  6. Call a technician if it persists: A recurring LC code after these checks usually points to a failing pump seal or internal hose, which needs professional repair.

FAQ

Can I keep using the washer after an LC error?
It’s best not to run full loads until you’ve found and fixed the leak, since water damage can build up unnoticed each cycle.

Is the LC code the same as an SE or TE error?
No — LC is specific to leak detection, while codes like the Samsung Washer TE Error Code: Causes and Fixes relate to temperature sensor faults instead.

Why does LC appear even when I don’t see water?
The sensor can be triggered by condensation or a very small drip that evaporates quickly, so check hose fittings even if the base looks dry.
