Samsung Washer Error Code 4C
Not filling (water supply) error. 4C, 4E or nF means water is not entering the washer correctly. Samsung lists closed or kinked supply hoses, a missing hot water connection, a drain hose pushed too far into the standpipe, and clogged inlet screens as common causes.
- Code: 4C (also shown as 4E, nF)
- Appliance: Samsung washer
- Owner fix: Often fixable with the safe checks on this page. Call a pro if the code comes back.
- Repair cost: call for a quote
- Checked against the manufacturer sources below on October 27, 2026
Likely causes
- Water valves not fully open
- Kinked supply hoses, or hot and cold hoses swapped
- Hot water line not connected (the washer may call for hot water even on cold cycles)
- Clogged inlet filter screens from sediment
- Drain hose inserted too far into the drain pipe (siphoning)
Safe checks you can do
Safety: Unplug the washer before touching the pump filter, hoses or drum. Water left inside can be hot and heavy, so put towels down first.
- Open both hot and cold valves fully and leave them open while the washer runs.
- Check that hot goes to hot and cold to cold, and that the hoses are not bent. Samsung says not to use Flood Safe hoses.
- Check that the drain hose sits about 6 to 8 inches into the drain pipe, not deeper.
- Unplug the washer or switch off its breaker for 1 minute, then try again.
- With the valves off, disconnect the hoses and clean the small inlet screens if you see debris. Hard water and sediment can clog them over time.
When to call a pro
- Water still does not flow with valves open and screens clean
- You hear the valve buzz but no water comes in
- The code returns every cycle
- Any time you smell burning or gas, see sparks, or would need to open a panel
