Samsung Washer code **1 LC** is associated with **low-water-level or leak-detection error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **1 LC**. Search normalization stores it as **1LC** 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 1LC 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
Samsung Washer code **1 LC** is associated with **low-water-level or leak-detection error**. The display identifies the system or condition the control detected, but it does not by itself prove which individual part should be replaced. 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 **1 LC**. Search normalization stores it as **1LC** while preserving the characters a homeowner actually sees.
Signs
Symptoms you may notice
While 1 LC is active, the appliance can receive too little water or fail to confirm the expected water level.
On affected Samsung washing machine models, the code often appears near the beginning of a fill stage.
On affected Samsung washing machine models, water can enter slowly, intermittently, or not at all.
1 LC can be accompanied by this pattern: 1 LC appears during the washer stage associated with low-water-level or leak-detection error.
The 1 LC display becomes more meaningful if 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.
As an external check for 1 LC, confirm the household water supply valve is fully open where the appliance uses one.
With 1 LC recorded, inspect accessible supply hoses for kinks and clean inlet screens only as described by Samsung.
With 1 LC recorded, verify whether water actually enters before the code appears.
For 1 LC, start by doing this: verify hot/cold hose routing and water pressure when relevant to the exact appliance.
The next non-invasive check is to record the code and the cycle stage where it appears.
With 1 LC recorded, check owner-accessible water supply, drain hose/filter, load balance, door, detergent, or power only when relevant.
Important safety warning. Disconnect power and stop use for active leakage near electrical parts, smoke, burning smell, or repeated breaker trips. For 1 LC, stop troubleshooting immediately if the symptom crosses into a safety hazard rather than a normal diagnostic condition.

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. A repeatable 1 LC event is more useful diagnostically than repeated resets, because it shows when the low-water-level or leak-detection error check is failing.

Seeing this code on your Samsung appliance?
Book a specialist visit for a clear estimate and approval before any repair.
Resetting can clear a temporary state, not a persistent issue. If **1 LC** comes back, preserve the code and move to the safe checks or model-specific service path.
Do not keep operating the appliance through a hazardous symptom just to see whether **1 LC** clears. If there is heat, water, electrical, gas, or food-safety risk, stop and arrange diagnosis.
Treat **1 LC** 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 1 LC** separate from same-looking codes used by other Samsung appliance families.
