Error Code: nF Difficulty: Easy
Problem: No fill – water not entering drum within 40 minutes
How to Fix nF Error
- Verify both hot/cold water valves fully open (turn counter-clockwise until stop).
- Disconnect inlet hoses at machine and check for screen filters clogged with sediment (clean with vinegar soak 15 minutes).
- Ensure hoses aren’t kinked behind machine – minimum bend radius 4 inches.
- Test water pressure at faucet (minimum 20 PSI required; use pressure gauge).
- Enter diagnostic mode: press Temp + Delay Start + Power simultaneously, then press Temp button 2 times to activate cold water valve.
- Listen for distinct valve click – if silent, check voltage at valve terminals (should read 120V AC during fill).
- Replace inlet valve assembly DC62-00243A if no voltage present at solenoid or screens clean but no water flow.
Samsung Washer NF Checks Before Replacing Parts
- Restart the washer and confirm the NF message returns under the same condition instead of after a one-time interruption.
- Check the simple causes first: load balance, water supply, drain flow, door or lid closure, visible leaks, and power stability.
- Inspect accessible wiring connectors and moisture-prone areas before assuming the control board has failed.
- Use the complete Samsung washer model number from the door, lid, or rear tag before matching any pump, valve, sensor, suspension, lock, or board category.
- If the NF code points to a specific system, test that system directly before ordering replacement parts.
Still Not Working?
If the replacement part didn’t fix the issue, you may have a wiring problem or main board failure.
