Seeing **LC1** on a Samsung washing machine narrows the problem to **low-water-level or leak-detection error**. What you do next depends on whether the code is an issue, a normal status/test message, or a model-dependent interpretation. The exact stage when the code appears can be as important as the characters themselves. Note whether it happens at startup, during fill, heating, cooling, draining, spinning, drying, or after a power event. The recorded display form is **LC1**. Search normalization stores it as **LC1** while preserving the characters a homeowner actually sees.

Quick answer
Low-water-level or leak-detection error.
Model compatibility: Samsung can reuse or reformat codes across series and model years, so LC1 may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Seeing **LC1** on a Samsung washing machine narrows the problem to **low-water-level or leak-detection error**.

Signs
Symptoms you may notice
LC1 can be accompanied by this pattern: the appliance may receive too little water or fail to confirm the expected water level.
Depending on the exact model, the code often appears near the beginning of a fill stage.
A symptom that fits LC1 is that water may enter slowly, intermittently, or not at all.
On affected Samsung washing machine models, lC1 appears during the washer stage associated with low-water-level or leak-detection error.
While LC1 is active, the cycle may pause, stop, retry, drain, or refuse to advance until the condition is cleared.

Before you call
Safe checks you can make
These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.
For LC1, start by doing this: confirm the household water supply valve is fully open where the appliance uses one.
Before opening any service area, verify accessible supply hoses for kinks and clean inlet screens only as described by Samsung.
Before requesting service for LC1, verify whether water actually enters before the code appears.
With LC1 recorded, verify hot/cold hose routing and water pressure when relevant to the exact appliance.
As an external check for LC1, record the code and the cycle stage where it appears.
To rule out an accessible cause, verify owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Safety takes priority over clearing LC1. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips.

When to request repair service
If supply flow is proven good and the display returns, inlet valves, flow/level sensing, wiring, or control electronics may require diagnosis. If LC1 keeps returning, record the stage at which it reappears so the technician can test the low-water-level or leak-detection error path instead of replacing parts by guesswork.

Book a specialist visit for a clear estimate and approval before any repair.
Resetting can clear a temporary state, not a persistent issue. If **LC1** comes back, preserve the code and move to the safe checks or model-specific service path.
Continue only if the appliance is otherwise safe and the owner-level checks are appropriate. Stop for leakage near electrical parts, smoke, burning odor, arcing, gas concerns, repeated breaker trips, uncontrolled heating, or unsafe temperatures.
Treat **LC1** as a starting point, not a replacement instruction. Wiring, feedback signals, operating conditions, and electronic controls can mimic a failed component.
The same-looking code can be reused on another Samsung appliance family or reformatted by region/model year. Match the appliance type and exact model before applying a meaning. This page therefore keeps **Washer LC1** separate from same-looking codes used by other Samsung appliance families.
