Plain-language answer

What the 4C or 4E code means

The washer is not receiving water correctly. Samsung groups 4C, 4E, nF, and related variants under a not-filling or water-supply problem.

This code points to a problem category. It does not prove that a specific internal part has failed.

Do these in order

Safe checks to try

  1. 1

    Confirm both water valves are open

    Check that the hot and cold supply valves are fully open. Some cold-labelled cycles can still use a small amount of hot water.

    What to look for: A closed or partly closed valve can restrict filling.
  2. 2

    Inspect the supply hoses

    Look behind the washer without moving it unsafely. Make sure the hoses are not sharply bent, crushed, or twisted.

    What to look for: Straighten only accessible hose bends. Stop if a hose is damaged or leaking.
  3. 3

    Check hot and cold connections

    Confirm that the hot hose reaches the hot inlet and the cold hose reaches the cold inlet.

    What to look for: Swapped lines can cause related hot and cold supply errors.
  4. 4

    Retry once

    Restore the water supply, power the washer, and start a short cycle.

    What to look for: If the code returns, do not keep resetting it without fixing the cause.

Stop and arrange service when

Stop if a hose is leaking, a valve is damaged, water is near electrical connections, the washer must be pulled out unsafely, or the code returns after the visible checks.
