Samsung Washer Error Code LC — What It Means & How to Fix It

What Does This Error Mean?

The LC error means your Samsung washer detected a water leak. A sensor inside the machine found water where it shouldn't be. This is a serious error — the washer stops immediately to prevent flooding. Do not ignore this. Water damage can be costly.

Affected Models

WF45R6100AW
WF50R8500AV
WF45T6000AW
WF42H5000AW
Most Samsung front-load washers

Common Causes

Loose or cracked water inlet hose connections at the back of the machine
Damaged door gasket (rubber seal) allowing water to leak past the door
Faulty or cracked internal hoses inside the washer cabinet
Leak detection sensor triggered by condensation or a small drip
Overloading the drum causing water to splash and reach the sensor

How to Fix It

Unplug the washer immediately and turn off the water supply valves.

Both steps are important. Unplugging stops the machine and turning off the valves stops more water from entering.
Check the water inlet hoses at the back of the machine.

Look for cracks, loose connections, or dripping. Hand-tighten any loose fittings. Replace cracked hoses — they cost about $10 at a hardware store.
Inspect the door gasket (the rubber ring around the door opening).

Look for tears, holes, or debris stuck in the folds. Clean the gasket with a damp cloth. A damaged gasket must be replaced.
Wipe dry the area under and around the washer.

The leak sensor can stay triggered if moisture remains. Dry the floor and base of the machine thoroughly before restarting.
Plug the washer back in and run an empty rinse cycle to test.

Watch closely for any dripping. If the LC error returns, a technician needs to inspect the internal hoses and sensor.

When to Call a Professional

If you cannot find a visible leak after checking hoses and the door seal, call a technician. Internal hose damage requires disassembling the machine. Samsung support or a licensed appliance tech is your best option. Expect repair costs of $100–$300 depending on the source of the leak.

Frequently Asked Questions

Is the LC error dangerous?

Yes — water leaks can damage floors, walls, and cabinets. Stop the washer and turn off the water immediately. Do not run the machine again until you find and fix the source of the leak. Act quickly to prevent expensive water damage.

Can the LC error be a false alarm?

Yes, it can. Condensation or a tiny splash can trigger the leak sensor. Try drying the area under the machine completely, then restarting. If the error returns on a dry machine, a real leak is likely present.

How do I reset the LC error on a Samsung washer?

Unplug the washer for 5 minutes, then plug it back in. This clears the error code from the display. But if the underlying leak is not fixed, the LC error will come back. Always find and fix the leak first.
