Error Code: 4C Difficulty: Easy
Problem: Water inlet valve malfunction or reversed hot/cold hose connections
How to Fix 4C Error
- Confirm hot/cold hoses connected to correct valves (marked H/C on machine rear panel).
- Swap hose connections temporarily to test if error follows hose position.
- Clean inlet screens thoroughly with soft brush and vinegar solution.
- Test individual valve solenoids in diagnostic mode (Temp + Delay Start + Power, then Temp button cycles through valves).
- Measure resistance across each solenoid (should read 2-4kΩ).
- Replace inlet valve assembly DC62-00243A if one solenoid fails to activate while other works normally or resistance out of spec.
Samsung Washer 4C Checks Before Replacing Parts
- Restart the washer and confirm the 4C 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 4C code points to a specific system, test that system directly before ordering replacement parts.
