Samsung LC
Water Leak Detected

What Your Machine Is Actually Telling You
LC (also LC1, LE, LE1 on some models) means Samsung's leak detection system found moisture in the base pan or at the bottom of the machine. This is a safety feature — the machine stops to prevent flooding.
Samsung's leak detection: A moisture sensor or float switch sits in the base pan under the drum. When water pools there, it triggers LC and shuts down all water-entry operations.
LC vs LE:
- LC = leak detected (newer models).
- LE = leak error (older models).
- LC1 = leak at the bottom of the machine specifically.
Common causes:
1. Door seal leak (25%) — gasket torn, worn, or debris under seal.
2. Drain hose connection (15%) — loose clamp where hose connects.
3. Inlet hose leak (15%) — rubber washer worn or hose cracked.
4. Detergent dispenser overflow (10%) — too much detergent causing overflow.
5. Internal hose (10%) — drum-to-pump hose loose.
6. Tub seal (10%) — bearing seal failure, water leaking from shaft.
7. Condensation/splash (10%) — false alarm from splashing, not actual leak.
8. Sensor fault (5%) — moisture sensor corroded or faulty.

What You're Probably Seeing Right Now
- LC on display — machine stopped mid-cycle.
- Water visible under or behind the machine.
- Floor is wet around the base.
- LC appeared suddenly — a hose let go.
- LC appears only during spin — seal leak under pressure.
DIY Fix — From Easiest to Hardest
1
Turn Off Water Supply (Immediately)
1. Close BOTH water taps behind the machine.
2. This prevents further water entry.
3. Unplug the machine.
4. Place towels to contain any standing water.

Find the Leak Source (10 minutes)
1. Pull the machine out.
2. Wipe everything dry.
3. Turn on the water taps slowly.
4. Watch carefully for where water appears:
- **Back** = inlet hoses or connections.
- **Bottom front** = door seal or drain pump.
- **Under center** = tub seal or internal hose.

- **Under center** = tub seal or internal hose.
3
Check Door Seal (5 minutes — 25% of Leaks)
1. Inspect the rubber door gasket all the way around.
2. Feel for tears, cuts, or hardened sections.
3. Check for debris stuck in the seal (coins, hair pins).
4. Clean the seal with a damp cloth.
5. If torn: replace the gasket ($30-80).

4
Check Hose Connections (5 minutes — 30% of Leaks)
1. **Inlet hoses:** tighten by hand + 1/4 turn. Replace rubber washers.
2. **Drain hose:** check the clamp at the pump connection.
3. **Internal hoses:** tilt machine back, inspect clamps.
4. Tighten any loose clamps with pliers.

5
Dry the Base Pan Sensor (5 minutes)
If the leak was minor and is fixed:
1. Tilt the machine back slightly.
2. Allow the base pan to drain and dry.
3. Use a towel or hair dryer.
4. Once dry: the sensor resets.
5. Power on and test.

6
Tub Bearing Seal Check (If Leak Is from Center)
If water drips from the center of the drum:
1. This is the tub seal around the drum shaft.
2. When this fails, water reaches the bearings.
3. You may also notice **brown/rust stains** on laundry.
4. This is a major repair: bearing + seal kit.
**Bearing + seal kit:** $50-150 DIY, $250-500 professional.

When to Call a Pro
- •Tub seal/bearing — $250-$500 installed (major repair).
- •Door gasket — $100-$250 installed.
- •Internal hose — $80-$200 installed.
- •Do not ignore LC — ongoing leaks cause floor/subfloor damage.
