Samsung Washer; United States. This page is not a brand-wide diagnosis.
The washer may pause, fail to fill, or show 4C, 4E, nF or a related not-filling code during a cycle.
Stop if water leaks, filling becomes abnormal, or the code returns after the official visible checks and one safe reset.
Record model code, supply state, hose condition, drain-hose position, reset attempt, and whether the code returned.

Samsung documents 4C, 1 4C, nF and 4E as not-filling errors and lists supply hoses, valves, drain-hose position, a one-minute power reset and inlet debris as first checks.
