Common interlock fault part on appliance no-start errors.
Samsung washers are sophisticated machines, but they are highly sensitive to load balance and water flow. When your washer stops mid-cycle and beeps with a code like DC or 5E, it’s usually not a broken part—it’s a safety sensor telling you that something is physically blocking the water or the drum.
Most Samsung washer errors can be resolved by redistributing the laundry or cleaning a filter.
What This Error Means
Samsung uses two-character codes (and sometimes their 4-character equivalents) to indicate sensor trips.
- DC / Ub: Unbalanced load. The drum can’t spin safely because the weight is lopsided.
- 4E / 4C: Water supply error. The washer isn’t getting water fast enough.
- 5E / 5C: Drain error. The water isn’t leaving the drum.
- LE / LC: Water leak detected or the drain hose is too low (siphoning).
Common Samsung Washer Error Codes
| Code | Meaning | Severity | Fix |
|---|---|---|---|
| DC / Ub | Unbalanced load | Low | Redistribute laundry |
| 4E / 4C | Water supply problem | Low | Check inlet screens |
| 5E / 5C | Drain problem | Moderate | Clean debris filter |
| LE / LC | Water leak / Siphoning | Moderate | Check drain hose height |
| nF | No fill (same as 4E) | Low | Check water valves |
Step-by-Step Fix
1. Resolving DC / Ub (Unbalanced Load)
This is the most common Samsung washer error.
- Open the door and check the laundry.
- The Fix: If you’re washing a single heavy item (like a rug or a heavy blanket), add a few towels to balance the weight. If the load is clumped on one side, spread it out evenly.
- Ensure the washer itself is level. Press down on the four corners; if it rocks, adjust the leveling legs.
2. Fixing 5E / 5C (Drain Problem)
If the washer is full of water and won’t spin:
- Locate the Debris Filter door at the bottom front of the machine.
- Place a towel and a shallow pan on the floor.
- Open the small drain tube to let the water out slowly.
- Unscrew the large filter cap. You will likely find coins, hairpins, or lint blocking the pump.
- Rinse the filter and screw it back in tightly.
3. Resolving 4E / 4C (Water Supply Problem)
- Ensure both the hot and cold water valves at the wall are fully turned on.
- Clean the Inlet Screens: Turn off the water, unscrew the hoses from the back of the washer, and use pliers to pull out the small mesh screens. Rinse them to remove sediment and reinstall.
- Check that the hoses aren’t kinked when you push the washer back against the wall.
4. Resolving LE / LC (Leak / Siphoning Error)
- Check the floor for water. If there’s no leak, check your Drain Hose.
- The Siphoning Fix: If the drain hose is pushed too far into the standpipe (more than 6 inches), it creates a vacuum that pulls water out of the machine while it fills. Pull the hose back and ensure there is an air gap.
- Ensure the drain hose is at least 24 inches high but no more than 96 inches.

When to Call a Professional
Samsung washers have a “Test Mode” that can diagnose motor and sensor failures.
- 3E / 3C: Motor error. This could be a failed hall sensor or a dead motor.
- Sud / Sd: Too many suds. You used too much detergent. The machine will wait for the suds to clear, but if it happens often, it can damage the pressure switch.
- Loud banging during spin: This usually indicates failed Suspension Rods (top-load) or Spider Arm (front-load). This is a major mechanical repair.
