Samsung Washer LC1 Error Code: What It Means & What to Check
Q: My Samsung washer is showing LC1. What does it mean, and what should I do first?
A: On many Samsung washers, LC1 is a leak / water level detection alert—very similar to LC. Translation: the washer thinks water is leaking (or the water level is changing in an abnormal way). It can be a real leak, a loose hose/clamp, oversudsing, a drain setup/siphoning issue, or a problem in the water-level sensing system.
What the Samsung LC1 Code Means
LC1 is commonly tied to the washer detecting moisture/leak conditions or unstable water level feedback. Many models will stop and/or drain as a protective measure to reduce the chance of overflow, floor damage, or electrical issues.
Common Symptoms
- Cycle stops and the washer drains
- LC1 appears during fill or wash
- Intermittent error that comes and goes
- Water under or behind the washer
- Soap suds lingering or foamy water
Safety First
- If you see water on the floor, pause the cycle and unplug the washer before inspecting.
- Turn off the hot and cold supply valves if you suspect an active leak.
- Avoid opening panels or working near wiring—leave internal inspection to a trained tech.
Quick Checks (Homeowner-Safe)
1) Look for small leaks (slow drips count)
- Inspect the fill hose connections at the wall and at the washer.
- Check around the drain hose where it meets the standpipe/laundry sink.
- Look for damp dust, streaks, or mineral marks under the washer (a clue for slow leaks).
2) Confirm hoses aren’t kinked or pinched
- Pull the washer forward slightly and make sure hoses have a smooth curve.
- Make sure the washer isn’t crushing hoses against the wall.
3) Rule out oversudsing
- Too much detergent (or non-HE detergent) can create excess foam and confuse water-level behavior.
- Run an empty rinse & spin. If suds remain, run a second rinse.
- On the next load, reduce detergent and verify the product is HE (for high-efficiency washers).
4) Check for siphoning / drain setup issues
- Make sure the drain hose isn’t pushed too far down into the standpipe (can cause siphoning).
- Confirm the standpipe/laundry sink drains freely (no backup that could spill water).
5) Power reset
- Unplug for 2 minutes, plug back in, and try a short cycle.
- If LC1 returns quickly, it’s likely not a one-time glitch.
Most Common Causes (and Likely Parts)
- External leak at fill hoses, drain hose, or loose connections
- Internal hose/clamp leak (slow seep that trips LC1 intermittently)
- Leak sensor / moisture detection triggered when water reaches the sensor area
- Water level/pressure sensing issue (pressure switch/sensor or pressure hose problem)
- Drain pump seal or pump housing seepage
- Main control board (less common; usually after other causes are ruled out)
When to Call Beacon
Call Beacon Services & Appliances if:
- LC1 keeps returning and you can’t find an obvious leak
- You see water under the washer (especially near the center/bottom)
- The washer drains unexpectedly or won’t complete cycles
- You want a confirmed diagnosis of the leak sensor, pressure system, or pump without guesswork
Our friendly technicians in yellow can track down the leak source (or confirm a sensing issue) and help you prevent repeat shutdowns. Request Service or call (352) 726-7530. You can also visit www.BeaconSaves.com.

FAQ: Samsung Washer LC1
Is LC1 different from LC on Samsung washers?
On many models they’re closely related and both point to leak detection or unstable water-level feedback. The safest approach is to treat LC1 like a leak/water-level warning and inspect for moisture, hose issues, oversudsing, and drain setup problems.
Can too much detergent cause LC1?
Yes. Oversudsing can interfere with normal water movement and cause the washer to react like there’s a leak condition. Run an empty rinse & spin and reduce detergent on the next load.
What’s the first place I should check for a leak?
Start at the simplest spots: fill hose connections at the wall and washer, then the drain hose area. Even a slow drip can trigger LC1 over time.
Why does my washer fill and then drain with an LC1 code?
The washer may be draining as a protective step if it thinks water is leaking or the water level reading is unstable. Also check for siphoning—don’t push the drain hose too deep into the standpipe.
What parts are commonly involved when LC1 won’t clear?
Common culprits include leak sensor/moisture detection, internal hoses/clamps, the pressure (water level) sensor/switch and its hose, and sometimes a drain pump seal or control board issues.
When should I stop and call Beacon right away?
If you see water pooling, notice repeated shutdowns, or smell anything electrical, stop use and call Beacon. Catching leaks early helps prevent floor damage and larger repairs.
