Error Code: E3 Difficulty: Hard
Problem: The washer detected an overflow level of water. This typically happens if the water inlet valve is stuck open and lets water in even when the machine is off.
How to Fix E3 Error
-
- UNPLUG washer from electrical power. Remove rear access panel.
- Manually rotate drum pulley. Listen for grinding noises or feel for excessive resistance indicating bearing failure.
- Disconnect motor wiring harness from main board. Label connections before removal.
- Test motor windings resistance between U-V, V-W, and W-U terminals. All readings must be equal (2-5Ω). Uneven readings indicate internal fault.
- Test hall sensor resistance per service manual pinout (typically
- 5-
- 5kΩ between sensor pins).
- If motor binds mechanically or electrical tests fail, replace entire motor assembly using OEM part DC34-00030A.
- Remove drive belt, stator mounting bolts (4-6 bolts), and rotor nut (requires rotor puller tool). Extract old motor.
- Install new motor assembly. Reattach rotor, stator bolts (torque to 22 ft-lbs), and drive belt with proper tension.
- Reconnect wiring. Run motor diagnostic test to verify rotation direction and speed.
Samsung Washer E3 Checks Before Replacing Parts
- Restart the washer and confirm the E3 message returns under the same condition instead of after a one-time interruption.
- Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability.
- Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed.
- Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
- If the E3 code points to a specific system, test that system directly before ordering replacement parts.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
