Samsung fill troubleshooting starts with water supplies, hoses, drain installation, and inlet screens.
What this guide covers
Error codes: 4C, 4E, NF · Symptoms: Won’t fill / filling very slowly
This guide follows a structured decision tree built from manufacturer troubleshooting information. It does not assume that the most commonly replaced part is the failed part, and it does not show an exact-fit replacement part unless model compatibility has been independently verified.

Safe troubleshooting sequence
Start with the observations and external checks that can be verified without opening energized assemblies. The interactive version asks these in order and changes the path based on your answers.
- Start with the water supplySamsung says to confirm the faucets are open and hoses are connected correctly.
- Inspect the supply hosesWrong connections, kinks, and pinches can trigger fill errors.
- Check drain-hose installationIncorrect drain installation can contribute to siphoning or fill behavior.
- Check the inlet mesh filtersSamsung says debris buildup in inlet screens can restrict water and trigger fill errors such as 4C.

Evidence strength: Strong
Clean the inlet mesh filters
Samsung specifically identifies clogged mesh screens as a cause of restricted filling and fill errors.
Evidence strength: Strong

If supply, hoses, drain installation, and inlet screens are correct and the fill problem persists, internal testing may be needed.
Evidence strength: Strong that service is next
When professional diagnosis is the safer next step
If supply, hoses, drain installation, and inlet screens are correct and the fill problem persists, internal testing may be needed.
Appliance Verdict stops before energized electrical testing, gas-system work, sealed-system work, and other checks that can create unnecessary risk. A technician can use the model, issue, and completed checks from the interactive diagnostic as a starting point.
Repair or replace?
A diagnosis and a repair decision are different questions. Once you have a real repair quote, compare the total repair cost with the all-in price of a comparable replacement. Warranty or protection-plan coverage, appliance age, reliability history, efficiency, and likely future repairs can all matter. Appliance Verdict’s interactive result includes a transparent cost comparison rather than a black-box replacement recommendation.
