Samsung Washer NF Error Code
If your Samsung washer displays NF, it typically means the washer is not filling with water the way it expects to. The good news: many NF causes are simple (a closed valve, kinked hose, or clogged inlet screen).
Quick Answer
Q: What does the Samsung washer NF error code mean?
A: NF usually means a no-fill / fill error—water is not entering correctly or the washer isn’t detecting proper water flow during the fill portion of the cycle.
Common Symptoms
- Washer starts, then pauses and displays NF
- Little or no water enters the tub
- Long fill times, then an error
- You may hear the valve “click” but no steady water sound
Safety First
- If water is leaking, stop the cycle and turn off the supply valves behind the washer.
- Before inspecting hoses/screens, unplug the washer (or switch off the laundry circuit if needed).
- Avoid moving the washer alone—washers can be heavy and awkward in tight laundry spaces.
Homeowner Quick Checks
1) Confirm both water valves are fully open
Make sure the hot and cold shutoff valves behind the washer are turned all the way on (counterclockwise).
2) Check hose routing and kinks
Verify the hot/cold hoses aren’t pinched, kinked, or crushed behind the washer. Also confirm the hot hose is on hot and cold is on cold.
3) Confirm the drain hose isn’t causing a siphon
If the drain hose is shoved too far down the standpipe (or the standpipe is too low), the washer can siphon water out while it tries to fill—leading to an NF error. The drain hose should have an air gap and be secured so it isn’t sealed tightly into the pipe.
4) Clean the inlet screens
Sediment can clog the small screens where the hoses connect to the washer’s inlet ports. Turn off the water, relieve pressure, remove the hoses, and gently rinse/brush the screens (don’t puncture them).
5) Verify home water pressure
Weak water pressure can trigger fill errors. If other faucets in the home also have low flow, you may have a plumbing supply issue. If it’s isolated to the washer, clogged screens/valves are more likely.
6) Try a simple reset
Unplug the washer for 2 minutes, plug it back in, and run a quick rinse/spin or a short cycle to see if NF returns.
Most Common Causes and Likely Parts
Water supply issue
- Closed/partially closed valve
- Kinked hose or incorrect hose hookup
- Low water pressure
Restriction at the inlet
- Clogged inlet screens
- Debris/sediment in hose or valve
Fill components failing
- Water inlet valve assembly (not opening, weak coil, internal blockage)
- Flow sensing / pressure detection issue (model-dependent)
- Wiring/connector issue to valve or sensor
Control or detection issue
- Control board not driving the valve correctly
- Signal not returning properly from a flow/pressure circuit
When to Call Beacon
If you’ve confirmed water supply is on, hoses aren’t kinked, inlet screens are clean, and the washer still shows NF, it’s time for a diagnostic. Fill errors often come down to a failing inlet valve assembly, a sensing issue, or a control/wiring problem.

FAQ
Is Samsung NF the same as “no fill”?
Yes—NF generally points to a fill problem where the washer isn’t getting water into the tub as expected (or isn’t detecting proper flow during fill).
Can a partially closed valve really cause an NF code?
Absolutely. If the supply valve is only partly open, the washer may fill too slowly and time out, triggering NF.
What are inlet screens and where are they?
They’re small mesh filters located at the washer’s water inlet ports where the hoses connect. They catch sediment before it enters the valve.
Why does the drain hose installation matter for an NF error?
If the drain hose is installed in a way that allows siphoning, water can drain out while the washer tries to fill. The washer “thinks” it isn’t filling correctly and may display NF.
If I cleaned the screens and NF comes back, what’s next?
The next most common causes are a failing water inlet valve assembly, a wiring/connector issue, or a model-specific flow/pressure sensing problem.
Is it safe to keep retrying cycles when NF shows up?
If there’s no leaking, it’s usually safe to stop and do the basic checks. But repeated retries can be frustrating and won’t fix a weak valve or sensing issue—calling Beacon can save time.
