Samsung Washer 4C / 4E Error Code - Water Supply Line Inflow Fault

What Caused This Error?

The control system reports 4C when the monitored condition described by the error code is outside the expected operating range. In this case, the most likely trigger is clogged mesh filter in water inlet hose connections. Other common contributors include frozen or kinked supply lines and defective water inlet solenoid valve.

Step-by-Step Diagnostic Check

1. Turn off supply tap, remove fill hoses, and flush mesh filter screens under running water.
2. Inspect supply hoses for severe kinks or pinches behind the machine.
3. Check water pressure from wall valve directly into a bucket.
4. Replace water inlet valve assembly if screens are clean but water flow is blocked electrically.
