Samsung Washer NF Error Code: No Fill Detected
Quick Answer
NF fires on some top-load Samsung models instead of 4E for the same water supply fault. Diagnosis and repair steps are identical to the 4C/4E error.
NF is the no-fill error displayed on certain Samsung top-load models, equivalent to the 4C and 4E codes on other models. The machine opened the inlet valve but the water level sensor did not detect any rise in pressure. Check both supply valves are open, inspect inlet screens for mineral buildup, and test the valve solenoid with a multimeter if those checks pass.
