Applies to
- Samsung appliances covered by the cited Samsung washing machine information and error codes article
- Displayed 4C / 4E / nF code in that Samsung support scope
Region: United States. This page does not generalize the code to every Samsung washer.
What the code means
The washer is not getting water correctly for the selected cycle. Samsung warns that hose connection, supply valves, drain-hose position, and inlet debris can all matter before service.
Confirmed: Samsung documents 4C, 4E and nF as not-filling errors. The official first checks are water supply, hose routing, drain-hose insertion, a one-minute power reset, and inlet debris checks where safe.
Can you keep using it?
Only after safe supply checks and only if the code clears.
When to stop
Stop if hoses leak, valves cannot be operated safely, the washer fills unpredictably, or power access is unsafe.
When to call a professional
Request service if the code continues after correct supply, hose, drain-hose, reset and visible inlet checks.
Safe checks
- Confirm both hot and cold hoses are on the correct inlets.
- Open both water valves fully and check hoses for bends or kinks.
- Check that the drain hose is inserted properly and not kinked.
- Unplug the washer or flip the breaker for one minute only if power access is safe.
Confirmed by the manufacturer
- Water is not entering the washer correctly.
- Supply hoses may be connected incorrectly or kinked.
- Water valves may not be fully open.
- Drain-hose position can affect filling behavior.
Commonly associated with this fault
- Inlet debris or blocked inlet screens can be compatible with Samsung’s documented checks.
Not confirmed for this exact model
- A failed inlet valve, control board, pressure sensor, or harness is not confirmed by 4C, 4E or nF alone.
Reset instructions
Samsung documents unplugging the washer or flipping the breaker for one minute, then restoring power and trying a cycle.
Use the one-minute reset once after visible supply and hose checks; do not keep cycling power if the code returns.
Information to collect before calling service
Record the model code, exact displayed code, valve positions, hose routing, drain-hose insertion depth, and whether debris was visible at the inlet screens.
