4E (shown as 4C or nF on some models) means the washer didn’t detect enough incoming water within its expected window. Samsung’s own troubleshooting treats this as a water supply issue first: hoses, valves, and inlet filters, not an internal washer fault.
Samsung Washer Error Code 4E (Not Filling)
4E means the washer isn’t getting enough water in time. Samsung’s fix starts with the supply hoses and valves, not the washer itself.
Meaning
Possible causes
No cause is certain until it has been checked on the appliance.
- Very likely Water supply valves not fully open
- Likely Kinked, bent, or pinched supply hose
- Possible Debris clogging the inlet filters where the hoses connect
First checks
- Confirm both hot and cold water valves behind the washer are turned fully open, and stay open while a cycle runs.
- Check both supply hoses for kinks, and make sure hot is connected to the hot inlet and cold to the cold inlet.
- With the water supply off, disconnect the hoses and inspect the small mesh filters inside the inlet connections for debris. Clean them if clogged, this is a common cause Samsung specifically calls out.
- Power cycle the washer: unplug or switch off the breaker for 1 minute, then restore power and run a cycle.
What not to do
- Requesting a part replacement before checking the inlet filters. Samsung lists debris in the filters as a specific, common cause of this exact code.
- Leaving Flood Safe hoses installed if the washer came with them. Samsung's own instructions say not to use these hoses on this platform.
An error code varies by brand
The same code can have a different meaning depending on the brand and model. Always check your appliance's manual before acting.
