The Samsung washer 4C error code means the machine did not fill with water in time. It is one of the most searched washer faults because a kinked hose or dirty mesh filter often causes it—not a failed control board. Use the checks below before booking a technician.

What 4C means
4C (sometimes shown as 4E on older panels) is a water supply timeout. The board waits for the level sensor to rise; if pressure stays low, it stops the cycle and shows 4C.
Fix steps
- Open the water tap fully and confirm household pressure is normal.
- Straighten the inlet hose; replace it if crushed behind the cabinet.
- Shut off water, unscrew the hose at the washer, and clean the inlet mesh screen.
- Reconnect firmly, run a rinse cycle, and listen for the valve click and fill sound.
- If the drum never fills, test or replace the inlet valve assembly.
When to call a pro
If the valve clicks but no water enters, or the pressure switch hose is cracked, parts diagnosis is safer than forcing cycles. Persistent 4C after a clean filter usually points to the valve or sensor.
Quick FAQ
Is 4C the same as 4E?
On many Samsung models, yes—both flag a fill problem. Follow the same hose and filter workflow.
Can I reset 4C without tools?
Power-cycle for 60 seconds after clearing the tap and filter. If 4C returns immediately, keep troubleshooting supply parts.
Tip: Label hot/cold hoses before removal so you do not reverse them on dual-inlet machines.
