Samsung washer 4C or 4E error code
likely causes and what to check
What it means
4C or 4E means the control expected water and didn't get it. The machine believes the taps are closed, the hoses are blocked, or the fill is far too slow.
Start here before touching the machine itself — on this code the most common causes live at the wall, not in the washer.

Verdict, in general terms
A 4C is usually free — taps, hoses, screens — or a $20–$45 inlet valve. Worth fixing at any age; this is one of the cheapest codes a washer can show.
